TECHNICAL FIELD

[0002] The present disclosure relates to peptides useful for treatment of diabetes and associated disorders.

BACKGROUND

[0003] The peptide hormone insulin, which is produced by .beta.-cells in the islets of Langerhans in the pancreas, is released in response to increasing blood glucose levels. Thus, glucose is removed from the blood by insulin dependent stimulation of glucose transporters located in the cell membranes of the target tissue, e.g. adipose tissue, skeletal muscle and liver. Insulin exerts its biological effects by binding to and activating the membrane-bound insulin receptor (IR), thereby initiating a cascade of intracellular signalling events, which regulate multiple biological processes such as glucose and lipid metabolism.

[0004] Currently, the treatment of diabetes, both type 1 and type 2 diabetes, relies primarily on insulin treatment. A complement to insulin treatment is long-acting glucagon-like peptide-1 (GLP-1) receptor agonists, i.e. derivatives that act on the same receptor as GLP-1. GLP-1 is a metabolic hormone that stimulates insulin secretion. Besides increasing insulin secretion from the pancreas in a glucose-dependent manner, GLP-1 is known to increase insulin-sensitivity in both .alpha.- and .beta.-cells; to increase .beta.-cell mass and insulin expression, post-translational modification, and secretion; and to decrease glucagon secretion from the pancreas. Other medications used complementary to insulin treatment for the purpose of lowering plasma glucose levels include DPP-IV inhibitors, Metformin, SGLT-2 inhibitors and sulfonylurea.

[0005] Certain drawbacks are associated with long term use of insulin, such as weight gain and increased risks of cancer and hypoglycaemia. Thus, there is a growing demand in the field for novel non-insulin compounds capable of, not only treating diabetes, by addressing insulin resistance and hyperglycemia, but also reducing associated and consequential complications.

[0006] Identification of novel compounds that can restore glucose metabolism and treat diabetes and related disorders is thus highly relevant. Multiple approaches can be contemplated, albeit none of which are obvious to the person of skill in the art.

SUMMARY

[0007] The present inventors have found peptides which stimulate .beta.-cell proliferation, have the ability to rescue .beta.-cell from apoptosis induced by glucotoxic conditions, and stimulate insulin secretion from rat INS-1 .beta.-cells as well as isolated mouse pancreatic islets. Furthermore, the present inventors found that in a glucose tolerance test, the peptides lowered plasma glucose levels in vivo and delayed onset of diabetes disease in BB lyp/lyp rats, a model for type 1 diabetes. Hence, the peptides of the present disclosure are suitable for use in the treatment of endocrine, nutritional and metabolic diseases and disorders.

DESCRIPTION OF DRAWINGS

[0062] FIG. 1. FOL-005 and FOL-014 induced proliferation of .beta.-cells

[0063] Addition of increasing concentrations of FOL-005 in solution induced increasing proliferation of INS-1 cells after 48 hours (FIG. 1A). Wells coated with FOL-005 and blocked with Bovine Serum Albumin (BSA) induced more proliferation of .beta.-cells compared to only BSA coated control (ctrl) wells (FIG. 1B). Wells pre-coated with FOL-014 and blocked with BSA induced more proliferation compared to only BSA coated wells (FIG. 10). Data is presented as counts per minute (CPM) relative unstimulated control (ctrl) cells. Mean.+-.SD are presented for 10-12 different observations in each group.

[0064] FIG. 2. FOL-005 protected .beta.-cells against glucotoxicity

[0065] INS-1 cells incubated during 48 h in 20 mM glucose displayed more apoptotic cells (Annexin V positive) compared to cells incubated at 5 mM glucose. Addition of FOL-005 to cells incubated with 20 mM glucose reduced the level of apoptotic cells compared to 20 mM glucose alone (FIG. 2A). Apoptosis measured by caspase-3 activity was increased in INS-1 cells at 20 mM compared to 5 mM glucose. Addition of FOL-005 diminished the rate of glucotoxicity-induced caspse-3 activity (FIG. 2B). Mean.+-.SD are presented for 4-8 different observations in each group.

[0066] FIG. 3. Insulin secretion was increased from islets and .beta.-cells following FOL-005 stimulation

[0067] FOL-005 stimulated .beta.-cell and islet insulin secretion. Insulin release from INS-1 cells was increased after FOL-005 (6 .mu.M) stimulation in-non glucose containing media compared to non-stimulated control (ctrl) and to a scrambled control peptide (FOL-015) (FIG. 3A). FOL-005 stimulated insulin release from INS-1 at both low (5 mM) and high (20 mM) glucose (FIG. 3B). Isolated mouse pancreatic islets stimulated with FOL-005 (6 .mu.M) or GLP-1 (100 nM) secreted more insulin compared to unstimulated control islets (FIG. 3C). Mean.+-.SD are presented for 5-6 different observations in each group.

[0068] FIG. 4. Insulin secretion was increased from islets and .beta.-cells following FOL-014 stimulation

[0069] FOL-014 stimulated insulin secretion from .beta.-cells and pancreatic islets. INS-1 cells stimulated with FOL-014 (6 .mu.M) secreted more insulin compared to unstimulated control cells (FIG. 4A). Isolated mouse pancreatic islets stimulated with FOL-014 (6 .mu.M) secreted more insulin compared to control islets (FIG. 4B). Addition of GLP-1 (100 nM) or FOL-014 (0.6 .mu.M) had no effect on insulin secretion. Mean.+-.SD are presented for 5-6 different observations in each group.

[0070] FIG. 5. The effect of FOL-014 on insulin secretion was dose dependent. Stimulation of INS-1 cells by increasing doses of FOL-014 resulted in a significant increase in insulin secretion for all concentrations tested. The insulin secretion increased in a linear fashion in the presence of FOL-014 ranging from 0.6 nM to 60 nM. Higher concentrations appeared to result in a less pronounced effect on insulin secretion. Furthermore, FOL-014 induced insulin secretion was comparable to the effect of 100 nM GLP-1. Bars represent mean values and standard error of the mean (SEM).

[0071] FIG. 6. The effect on insulin secretion of FOL-014 was glucose concentration dependent. The insulin secretion from untreated or FOL-014 exposed INS-1 cells was measured in the presence of increasing glucose concentrations. At glucose levels 5.5 mM or higher, the insulin secretion was significantly higher in the FOL-014 treated cells, as compared to untreated control cells. Bars represent mean values and standard error of the mean (SEM).

[0072] FIG. 7. FOL-005 and FOL-014 dosed together with native GLP-1 elicited an additive effect on insulin secretion. The insulin release from INS-1 cells was measured following combination treatment of GLP-1 together with FOL-005 and FOL-014 (all three peptides in a concentration of 100 nM), respectively and compared with the effect of each peptide alone. The combination of GLP-1 and FOL-014 significantly increased the insulin secretion as compared with each peptide alone. An increase was also observed for the combination of FOL-005 and GLP-1. Bars represent mean values and standard error of the mean (SEM).

[0073] FIG. 8. FOL-014 affected insulin and glucagon secretion in pancreatic islets. Two different concentrations of FOL-014 were tested and compared with the effect of 100 nM GLP-1 on isolated mouse islets in low (2.8 mM) (A, C) and high (16.7 mM) (B, D) concentrations of glucose. In the low glucose samples, the presence of FOL-014 did not increase insulin secretion, but reduced glucagon secretion as compared with control and GLP-1. In the high glucose samples, 600 nM FOL-014 and GLP-1, but not 6 .mu.M FOL-014, significantly increased insulin secretion (B), and GLP-1 as well as both concentrations of FOL-014 efficiently reduced glucagon secretion (D). Bars represent mean values and standard error of the mean (SEM).

[0074] FIG. 9. FOL-014 lowered plasma glucose levels in vivo following a glucose injection. An intraperitoneal glucose tolerance test (IPGTT) was performed on wild type C57bl/6 mice. FOL-014 dosed at 200 nmol/kg significantly lowered the plasma glucose levels as compared to the control at 15 minutes, 30 minutes and 45 minutes (P=0.0027). At the 30 nmol/kg dose, FOL-014 lowered the glucose levels with a significant effect at 45 minutes after the glucose injection. The dotted line corresponds to mean non-fasting glucose levels. Data represents mean values and standard error of the mean (SEM). Statistical analysis was performed using student's t-test.

[0075] FIG. 10. FOL-014 delayed the onset of type-1 diabetes in BB lyp/lyp rats. BB lyp/lyp rats treated with FOL-014 showed a significant delay in the onset of diabetes defined as plasma glucose<11.1 mmol/l. Age of onset of diabetes for each rat was depicted in (A) with a significant difference between untreated and treated groups. The percentage of animals developing type 1 diabetes each day was depicted in (B) with a significant difference between groups. Error bars in (A) represent standard error of the mean (SEM).

[0076] FIG. 11. The effect on insulin secretion of peptide analogues derived from FOL-005 or FOL-014. Novel peptide analogues were tested in two separate INS-1 cell lines (A and B) for their ability to induce insulin secretion under high glucose (16.7 mM) conditions. The effect was compared with that of native GLP-1, FOL-005 and FOL-014 as well as the effect of high glucose alone. Analogues inducing insulin release below the average of the high glucose control were considered non-functional (not shown). The level of insulin secretion is depicted in black, filled bars for the novel analogues, and in contrasting patterns for the comparators. Bars represent mean values and standard error of the mean (SEM).

[0077] FIG. 12. FOL-005 and FOL-014 displayed specific distribution patterns following injection in mouse. Following subcutaneous administration of .sup.3H-FOL-005, the highest overall levels of radioactivity were present in pancreas and at the injection site, 1 hour (A) and 2 hours (B) after injection. Accumulation of the .sup.3H-FOL-005 is also visible in liver, kidney, salivary glands. Using Pearl Trilogy Small Animal Imaging System in vivo bio-distribution and tissue localization of Cy7.5 labelled FOL-005 (C) and FOL-014 (D) in NMRI nude mice via subcutaneous injection was investigated. Following initial control imaging, a dose of 10 nmol per mouse was administered and live imaging was performed at 5 min, 20 min, 50 min, 60 min, 2 hrs, 4 hrs, 6 hrs, 24 hrs and 48 hrs. High accumulation of both peptides was evident in the pancreatic region as well as at the injection site.

EXAMPLES

[0392] The disclosure is further illustrated by the following examples, which however should not be construed as being limiting for the disclosure. These examples demonstrate that exemplary peptides of the present disclosure stimulate .beta.-cell proliferation, and have the ability to protect and rescue .beta.-cells from apoptosis induced by glucotoxic conditions. It is also demonstrated that the exemplary peptides have the ability to stimulate insulin secretion from rat .beta.-cells as well as isolated mouse pancreatic islets, where the peptides also are demonstrated to reduce glucagon levels. Furthermore, the examples demonstrate that the peptides reduce plasma glucose levels in vivo in a glucose tolerance test and that the peptides delay onset of type 1 diabetes in BB lyp/lyp rats

Example 1: Peptide Design

[0393] The novel peptides were designed following rational structure activity investigations. For FOL-005 (SEQ ID NO: 1) the peptides were designed around the RGD site but mutated in order to generate different structures that potentially could interact with different integrins. A sequence similar to FOL-005 was identified in the third fibronectin type III repeat domain (TNfn3) in tenascin-C and found to be reasonably similar to the mutated RGD site of FOL-005. A peptide was designed from this sequence denoted FOL-014. The X-ray crystal structure of the tenascin-3 TNfn3 domain (PDB code 1TEN, Leahy et al. (1992) Science 258(5084):987-91) was analyzed. The FOL-014 (SEQ ID NO: 136) sequence span the beta-turn before and the entire 3rd beta sheet. FOL-014 variants were designed to allow for structural modification and stabilization of the 3-dimensional molecular structure. Specifically, the peptides variants covered the beta-turn region with exposed side chains and some cyclized variants to maintain geometry.

[0394] All peptides were synthesized by solid phase peptide synthesis using several peptide manufacturers. Mainly, the peptide variants have been provided by Biopeptide Inc., California.

Example 2: FOL-005 and FOL-014 Induced Proliferation of INS-1 Cells

[0395] To investigate if FOL-005 and FOL-014 could induce proliferation of .beta.-cells we used INS-1 cells. Rat INS-1 cells were seeded in 96-well plates in RPMI medium with supplement and after 2 hours the medium was changed to RPMI without supplement. During the proliferation experiment the cells were incubated at different test conditions (FOL-005, FOL-014, coated or in solution, 48 h incubation) and during the last 20 hours of culture period the cells were pulsed with 1.mu. Ci/well of [methyl-3H] thymidine. The cells were then harvested onto glass fiber filters using a FilterMate harvester. The filters were air dried, and the bound radioactivity was measured using a liquid scintillation counter. To study whether FOL-005 influenced .beta.-cell proliferation, INS-1 cells were treated with increasing amounts of soluble FOL-005 (0.06-6 .mu.M) during 48 hours and proliferation was measured with radiolabeled thymidine incorporation into newly synthesized DNA. FOL-005 stimulated INS-1 cell proliferation (FIG. 1A). Wells coated with either FOL-005 or FOL-014 and later blocked with bovine serum albumin (BSA) before addition of INS-1 cells also stimulated proliferation compared to control (ctrl) coated wells (FIG. 1B-C).

[0396] This demonstrated that FOL-005 and FOL-014 interacted with .beta.-cells and induced proliferation.

Example 3: FOL-005 Protected n-Cells from Glucotoxicity

[0397] Since glucotoxicity in pancreatic .beta.-cells is a well-established process in type 2 diabetes we next investigated the protective effects of FOL-005 on .beta.-cells during glucotoxic conditions. First we confirmed that 20 mM glucose induced cell apoptosis in INS cells after 48 h of exposure. High glucose (20 mM) containing RPMI medium induced more Annexin V positive cells and more caspase-3 activity in INS cells compared to cells incubated with medium containing 5 mM glucose (FIG. 2A-B). Exposure of INS-1 cells to 20 mM of glucose at the same time as FOL-005 decreased cell apoptosis as detected both by Annexin V staining and by caspase-3 activity (FIG. 2 A-B). The rate of apoptosis in INS-1 cells was measured with either Caspase-3 Assay Kit or stained with Annexin V Apoptosis Detection Kit with 7-AAD. Caspase-3 activity was measured with fluorescence at an excitation wavelength of 380 nm and an emission wavelength of 440 nm. Caspase-3 activity was then normalized to protein concentration in each well. Measurements of Annexin V stained cells were performed using a CyAn ADP flow cytometer and analyzed with Summit V4.3 software.

[0398] In conclusion, it is well known that glucotoxicity induces .beta.-cell apoptosis, however in the presence of FOL-005 glucotoxicity-induced apoptosis was diminished.

Example 4: FOL-005 Induced Insulin Secretion from INS-1 Cells

[0399] To investigate the stimulatory effect of FOL-005 on insulin secretion, INS-1 .beta.-cells were used in the following experiments. Cells were seeded overnight in cRPMI and then washed with PBS before pre-incubation for 60 min at 37.degree. C. in Krebs-Ringer bicarbonate buffer (KRB), pH 7.4, supplemented with 10 mM HEPES, 0.1% bovine serum albumin. After pre-incubation, the buffer was changed and the INS-1 cells were incubated at different test conditions (0 mM, 5 mM or 20 mM glucose) and stimulated with peptide FOL-005 or FOL-015 (SEQ ID NO: 158) or left untreated during 60 min at 37.degree. C. Immediately after incubation, an aliquot of the buffer was removed and frozen for subsequent assay of insulin with an insulin radioimmunoassay kit.

[0400] The results demonstrated that .beta.-cells stimulated with FOL-005 peptide secreted more insulin compared to unstimulated control cells or to cells stimulated with the FOL-015 control peptide (FIG. 3A) under conditions without glucose. INS-1 .beta.-cells subjected to glucose (5 mM or 20 mM) responded with insulin secretion after FOL-005 peptide (6 .mu.M) stimulation (FIG. 3B). INS-1 cells stimulated with 6 .mu.M FOL-005 peptide in the presence of 20 mM glucose responded with more insulin secretion compared to FOL-005 stimulated cells incubated with 5 mM glucose (FIG. 3B).

Example 5: FOL-005 Induced Insulin Secretion from Mouse Pancreatic Islets

[0401] Mouse pancreatic islets were isolated from 8-week old C57BL/6J male mice (Taconic). Mice were sacrificed by an overdose of isoflurane and cervical dislocation. 3 ml of 0.9 U/ml collagenase P was injected into the pancreatic duct to inflate the pancreas. The pancreas was then removed and collagen digested for 19 min at 37.degree. C. The samples were vigorously shaken to disrupt the tissue. The digest was transferred into ice cold Hank's Balanced Salt Solution (HBSS) with Ca.sup.2+ and Mg.sup.2+. The suspension was allowed to sit for 10 min to allow the islet to sink, and the islets were washed in fresh HBSS four times. The islets were then hand-picked and sorted according to size. Islets (n=3 per well in a 96 well plate) were pre-incubated in KRB buffer during 10 min 37.degree. C., pH 7.4, supplemented with 10 mM HEPES, 0.1%) bovine serum albumin. After pre-incubation, the buffer was changed and islets were incubated at different test conditions in new KRB buffer with 0.1%) bovine serum albumin (non-treated ctrl, FOL-005 peptide, or GLP-1) for 60 min at 37.degree. C. Immediately after incubation, an aliquot of the buffer was removed and frozen for subsequent assay of insulin.

[0402] The results demonstrated that isolated mouse pancreatic islets stimulated with GLP-1 (100 nM) or FOL-005 (6 .mu.M) secreted more insulin compared to unstimulated control islets (FIG. 3C).

Example 6: FOL-014 Induced Insulin Secretion from INS-1 Cells

[0403] INS-1 .beta.-cells were used to investigate the stimulatory effect of FOL-014 on insulin secretion. Cells were seeded overnight and then washed with PBS before pre-incubation for 60 min at 37.degree. C. in Krebs-Ringer bicarbonate buffer (KRB), pH 7.4, supplemented with 10 mM HEPES, 0.1% bovine serum albumin. After pre-incubation, the buffer was changed and the INS-1 cells were incubated in new KRB buffer supplemented with 10 mM HEPES, 0.1% bovine serum albumin and stimulated with peptide FOL-014 or left untreated during 60 min at 37.degree. C. Immediately after incubation, an aliquot of the buffer was removed and frozen for subsequent assay of insulin.

[0404] The results demonstrated that .beta.-cells stimulated with FOL-014 peptide secreted more insulin compared to unstimulated control cells (FIG. 4A).

Example 7: FOL-014 Induced Insulin Secretion from Mouse Pancreatic Islets

[0405] Mouse pancreatic islets were isolated from 8-week old C57BL/6J male mice as described under example 5. The islets were then hand-picked and sorted according to size. Islets (n=5 per well in a 96 well plate) were pre-incubated in 200 .mu.l KRB buffer during 10 min 37.degree. C., pH 7.4, supplemented with 10 mM HEPES, 0.1% bovine serum albumin. Following pre-incubation, the buffer was changed and islets were incubated in different test conditions in new KRB buffer with 0.1% bovine serum albumin (non-treated ctrl, FOL-014 peptide, and GLP-1) for 60 min at 37.degree. C. Immediately after incubation, an aliquot of the buffer was removed and frozen for subsequent assay of insulin. The result show that mouse pancreatic islets stimulated with FOL-014 (6 .mu.M) secreted more insulin compared to unstimulated control islets (FIG. 4B). GLP-1 (100 nM) or FOL-014 (0.6 .mu.M) did not affect insulin secretion (FIG. 4B).

Example 8-11: Stimulation of Insulin Secretion from INS-1 Cell Lines by FOL-014, FOL-005 and Related Peptides

[0406] Materials and methods: Rat INS-1 .beta.-cells (passages 60-70) were cultured at 37.degree. C. and 5% CO.sub.2 in cRPMI media (RPMI 1640 supplemented with 10% fetal bovine serum, 50 IU/mL penicillin, 50 mg/L streptomycin, 10 mM HEPES, 2 mM L-glutamine, 1 mM sodium pyruvate, and 50 .mu.M beta-mercaptoethanol) unless otherwise stated. INS-1 cells were seeded in 96-well plates (2.times.10.sup.3 cells/well) in cRPMI medium and following overnight incubation, the cells were washed in PBS before pre-incubation for 120 min at 37.degree. C. in Krebs-Ringer bicarbonate buffer, pH 7.4, supplemented with 10 mM HEPES, 0.1% bovine serum albumin and 2.8 mM glucose. Following pre-incubation, the buffer was exchanged with fresh Krebs-Ringer buffer as described above and supplemented with specific glucose concentrations and peptides for the individual experiments as described below. Immediately after 60 minutes incubation at 37.degree. C., an aliquot of the buffer was removed and frozen for subsequent insulin ELIZA assay.

Example 8. FOL-014 Induced Insulin Secretion is Dose-Dependent in a Non-Linear Manner

[0407] Insulin release from INS-1 cells were measured following exposure to increasing concentrations of FOL-014 and compared with the stimulatory effect of GLP-1 and untreated control during high glucose concentration (16.7 mM). All concentrations of FOL-014 tested elicited significantly higher insulin release as compared with the untreated control. At 6 nM or higher, FOL-014 triggered insulin release within the same range as 100 mM GLP-1. At concentrations ranging from 0.6-60 nM, insulin secretion increased in a linear fashion in relation to increasing FOL-014 concentrations. Exposure to FOL-014 concentrations 600 nM did not increase the insulin secretion (FIG. 5).

[0408] The results demonstrated that FOL-014 significantly increased insulin secretion from INS-1 .beta.-cells in vitro in a non-linear dose dependent fashion.

Example 9. The Capacity of FOL-014 to Induce Insulin Secretion is Glucose Dependent

[0409] Insulin release from INS-1 cells was measured following exposure to 60 nM FOL-014 at increasing concentrations of glucose. In untreated control samples, elevated glucose concentrations increased the insulin secretion at 11.1 mM glucose or higher. In the presence of FOL-014, insulin secretion increased significantly in a glucose dependent fashion already from 5.5 mM glucose. (FIG. 6).

[0410] The results demonstrated that the presence of FOL-014 significantly increased insulin secretion from INS-1 .beta.-cells in vitro in a glucose concentration dependent fashion and that FOL-014 was effective also at marginally elevated glucose levels.

Example 10. FOL-014 or FOL-005 in Combination with GLP-1 Increased Insulin Secretion as Compared with Either Peptide Alone

[0411] Insulin secretion from INS-1 cells was measured following exposure to FOL-005, FOL-014, GLP-1 or combinations of those, expressed as percentage of untreated control. The combined effect of GLP-1 and FOL-014 resulted in a significantly higher insulin release than GLP-1 or FOL-014 alone. The additive effect of the combination of FOL-005 and GLP-1 was less pronounced, but did however increase the insulin secretion as compared with GLP-1 alone. The experiments were performed in the presence of 16.7 mM glucose (FIG. 7).

[0412] The results demonstrated that the combination of GLP-1 and FOL-014 could further potentiate the insulin secretion from INS-1 cells in vitro as compared with each peptide alone. Furthermore, the combination of FOL-005 and GLP-1 tendentially increased insulin secretion.

Example 11. The Ability of Novel Peptide Analogues to Induce Insulin Secretion in Pancreatic .beta.-Cell-Lines was Investigated

[0413] Novel peptide analogues, derived from either FOL-005 or FOL-014 were tested concerning their ability to induce insulin secretion in two separate INS-1 cell lines in the presence of 16.7 mM glucose. FOL-005, FOL-014 and GLP-1 as well as a high glucose (16.7 mM) and a low glucose (2.8 mM) control (not shown) was included in each experiment and the peptide concentration was 100 nM. In order to correct for the variance between experiments, all values were normalized to, and expressed as percentage of the average value of the high glucose control in the individual experiments. The analogues were subsequently ranked according to performance (FIGS. 11A and 11B). Peptide analogues eliciting an insulin response below the high glucose control average value were considered non-functional and were hence excluded (not shown).

[0414] The results demonstrated the capacity of several novel peptide analogues to enhance insulin secretion from INS-1 .beta.-cells in vitro.

Example 12. FOL-014 Increase Insulin Secretion from Mouse-Derived Pancreatic Islets

[0415] Twelve-week-old male C57/bl6 mice were euthanized with isoflurane and cervical dislocation. After clamping the hepatic ducts, 3 ml of 0.9 U/ml collagenase P was injected into the bile duct to inflate the pancreas. The pancreas was then removed and digested for 19 min at 37.degree. C. The samples were vigorously shaken to disrupt the tissue. The digest was quickly transferred into ice cold Hank's Balanced Salts Solution with Ca.sup.2+ and Mg.sup.2+. The suspension was allowed to sit for 8 min to allow the islet to sink, and the islets were washed in the same manner our times. The islets were then handpicked and sorted according to size.

[0416] Freshly isolated islets were seeded in groups of 5 in a 96-well plate and preincubated for 1 h at 37.degree. C. in a Krebs-Ringer bicarbonate buffer (pH 7.4). The islets were incubated for 1 h at 37.degree. C. in Krebs-Ringer buffered solution supplemented with 0.6 or 6 .mu.M FOL-014 or 100 nM GLP-1 or left unsupplemented for control. Immediately after incubation, the medium was removed for assays of insulin and glucagon using Mercodia's ELISA kits. The effect of FOL-014 on insulin (FIGS. 8A and B) and glucagon (FIGS. 8C and D) secretion from isolated mouse islets was measured in the presence of low glucose (2.8 mM; FIGS. 8A and C) or high glucose (16.7 mM; FIGS. 8B and D) concentrations. A significant effect of FOL-014 was observed in the presence of high glucose for insulin and in the presence of both high and low glucose for glucagon. The effect of FOL-014 differed from that of GLP-1, which enhanced insulin secretion also in low glucose samples but failed to inhibit glucagon secretion in low glucose conditions.

[0417] The results demonstrated that FOL-014 enhanced insulin secretion and inhibited glucagon secretion in pancreatic islets.

Example 13. FOL-014 Reduced Plasma Glucose Levels in an Intraperitoneal Glucose Tolerance Test (IPGTT) in Mice

[0418] Whole blood was collected for glucose and insulin measurements from 10-week-old wild type male C57bl/6 mice. After a 4 hour fast, the mice were divided into three groups and given an intraperitoneal injection (ip) of either saline, 30 nmol/kg peptide (FIG. 9A) or 200 nmol/kg peptide (FIG. 9B). 15 min after the FOL-014 or saline (control) injections, the mice were administered 2 g of glucose/kg ip. Blood glucose concentrations were measured at 5, 15, 30, 45 and 60 minutes after the glucose injection. Statistical calculations were performed using student's t-test. FOL-014 dosed at 200 nmol/kg significantly lowered the plasma glucose levels as compared to the control when measured as area under the curve. In addition, the difference was significant at 15, 30 and 45 minutes. At the 30 nmol/kg dose, FOL-014 lowered the plasma glucose levels with a significant effect at 45 minutes after the glucose injection.

[0419] The results demonstrated that FOL-014 could lower plasma glucose levels in a glucose tolerance test performed on healthy wild type mice.

Example 14. FOL-014 Delayed Onset of Type 1 Diabetes in BB Lyp/Lyp Rats

[0420] BB lyp/lyp rats were randomized for placebo (sodium chloride, 9 mg/ml) or FOL-014 treatment 3 times/week from day 40 until onset of type 1 diabetes, defined as plasma glucose levels 11.1 mM. The dose of 100 nmol/kg FOL-014 peptide in saline or placebo (saline) was administered subcutaneously and the animals were terminated immediately upon exceeding critical plasma glucose levels. The difference between FOL-014 treated animals and animals receiving placebo treatment was significant both when expressed as average age for onset of type 1 diabetes (FIG. 10A) and when described as percentage of animals developing type 1 diabetes per day (FIG. 10B).

[0421] The results demonstrated that FOL-014 treatment significantly delayed the onset of type-1 diabetes in BB lyp/lyp rats.

Example 15. FOL-005 and FOL-014 Displayed Organ Specific Distribution Patterns in Mice

[0422] 057BI/6 mice were injected subcutaneously with H.sup.3 labelled FOL-005 and euthanized at 1 h (FIG. 12A) or 2 h (FIG. 12B) after injection. Following whole body sectioning the distribution of the labelled peptide was visualised. Strong binding was evident in pancreas and at the site of injection. Using Pearl Trilogy Small Animal Imaging System, in vivo bio-distribution and tissue localization of two Cy7.5 labelled peptides, FOL-005 (FIG. 12C) and FOL-014 (FIG. 12D) in NMRI nude mice via subcutaneous injection was investigated. High accumulation of the peptide was evident in the pancreatic tissue area. The same distribution pattern was found after i.v. administrations (not shown). The dose of each peptide was 10 nmol per mouse. The mice were imaged before injection, at 5 min, 20 min, 50 min, 60 min, 2 hrs, 4 hrs, 6 hrs, 24 hrs and 48 hrs post administration of labelled peptide.

Example 16. Tissue Specific Imaging for Diagnostic Use

[0423] Agents prepared as defined herein above are labelled by conjugation to suitable imaging probe or moiety, using methods known by those of skill in the art. The conjugated peptide-probe agents are subsequently administered to a subject and biodistribution is subsequently monitored e.g. up to 48 h after administration. The conjugated agent is thus used as a diagnostic or prognostic tool for investigation of pancreatic status. As such, the conjugated agents are suitable for detecting, diagnosing, or monitoring disease, disease processes and progression, susceptibility, as well as to determine efficacy of a treatment. The agents are particularly suited for monitoring the diabetic status of a subject. The conjugated agents are also used for monitoring and/or predicting risk of developing a disease, specifically diabetes.
