Diabetes mellitus is a chronic metabolism disorder characterized by hyperglycemia due to insulin deficiency or insulin resistance. Associated complications include Myocardial infarction, cardiomyopathy, retinopathy, neuropathy, nephropathy, etc.
Cinnamic acid analogs (SSPC0-SSPC20) containing different amino acids were designed and docked into crystal structure of AMPK and PPARs. Among the 20 designed compounds five compounds namely SSPC5, SSPC8, SSPC11, SSPC14, SSPC15 showed good docking scores using Glide 5.0 Maestro program and were subjected to ADME prediction by using software Quickprop version 3.1. These were then selected for synthesis, characterized and antidiabetic activity carried out using Alloxan induced diabetic rat model by measuring blood glucose levels using glucometer at 0, 1, 2, 4, 6, 8 and 24 hrs through the tail vein puncture method. SSPC5, SSPC8, SSPC11, SSPC14 showed % reduction in blood glucose of 23.02%, 37.02%, 14.04% and 15.96% as compared to standard with 33.53% reduction.
As SSPC14 had good and comparable docking scores in both AMPK and PPAR γ receptor, so it was subjected for the Diabetic as well as diabetic cardiomyopathy activity by recording the electrocardiogram of both diabetic and control rat. It was found to be very efficient at low dose and had a prolong duration of action on the heart (Up to 54 hrs). Thus this study indicated that such hybrid antidiabetic drug with dual action on hyperglycemia and cardiac function is desirable and cost effective.
