the present Compound Compound 13 and Compound were injected subcutaneously at or nM dose alternate day up to day 28 The same dosage regimen was administered in semaglutide treatment Measurements of blood glucose levels and body weight were done Insulin was measured on Day day 14 and day Cumulative food intake and body weight change was calculated on day 14 and Insulin data was analyzed by two way ANOVA followed by posttests using PRISM Pad version Whereas Blood Glucose Body weight change and Cumulative food intake data was analyzed by one way ANOVA followed by posttests using PRISM Pad version From day 29 to day animals were kept on recovery period during which no drug treatment was Blood Glucose and Body weight was measured during this On day Body weight Insulin was The results are provided in Tables 11 and 12 Table HbAlC Compound 1 Compound 13 Compound 16 Table Insulin Compound 1 Compound 13 Compound 16 Table Cumulative food Blood Glucose and Body Weight Compound 1 Compound 13 Compound 16 vs Diabetic vs One way ANOVA followed by Bonferroni posttests The representative compounds of the present disclosure 13 and at about 3 nM and 6 nM dose showed significant reduction in blood food consumption and body weight when compared to control The reduction was comparable to that shown by semaglutide at about 12 nM the effect was seen even after 29 days 13 and which demonstrates the potential of compounds of present invention for developing long acting drug which do not require frequent administration and hence adding to the patient Table Recovery Glucose AUC Table Recovery and Insulin vs Diabetic Control and vs One Way ANOVA followed by posttests These results demonstrate that the compound of present invention can find potential use for the treatment of diabetes and insufficientOCRQuality
