Abstract

This study aims at synthesizing novel di-morpholine 1,3,5-triazine derivatives as antidiabetic agent via inhibition of dipeptidyl peptidase-4 (DPP-4). The molecules were developed via sequential nucleophilic reaction to afford target derivatives 5(a-f) and subsequently tested for inhibitory potency against DPP iso-enzymes, such as DPP-4, DPP-8, and DPP-9. The in vitro inhibition assay suggested that these derivatives prominently and selectively inhibit DPP-4 over -DPP-8 and DPP-9. These molecules also showed no presence of cardiotoxicity, as confirmed by no activity against human Ether-à-go-go related gene channel. The study disclosed compound 5c as the most potent inhibitor of DPP-4 with IC50 of 1.10 nmol/L as compared to the standard. Compound 5c was further evaluated for oral glucose tolerance test (OGTT) and antidiabetic activity in ICR mice and Wistar rats, respectively. In OGTT, compound 5c showed dose-dependent -improvement of glucose tolerance with a maximum at 30 mg/kg. It also showed reduction in area under the curve from 0 to 120 min, similar to alogliptin (standard). In Wistar rats, compound 5c causes reduction in the blood glucose level, total cholesterol, triglyceride, low density lipoprotein (LDL) and very LDL le...Continue Reading

ApoE, Lipids & Cholesterol

Serum cholesterol, triglycerides, apolipoprotein B (APOB)-containing lipoproteins (very low-density lipoprotein (VLDL), immediate-density lipoprotein (IDL), and low-density lipoprotein (LDL), lipoprotein A (LPA)) and the total cholesterol/high-density lipoprotein (HDL) cholesterol ratio are all connected in diseases. Here is the latest research.

Cardiotoxicity

Cardiotoxicity refers to the muscle damage or dysfunction of heart electrophysiology caused by drug intake or due to disease complications. It is a well-known side effect of several cytotoxic drugs, especially of the anthracyclines and can lead to long term morbidity. Here is the latest research.
