Phase I clinical studies of the advanced glycation end-product (AGE)-breaker TRC4186: safety, tolerability and pharmacokinetics in healthy subjects.

Background And Objective: Advanced glycation end-products (AGEs) have been implicated in the pathogenesis of diabetic complications through a variety of mechanisms including endothelial dysfunction and structural abnormalities in the vasculature and myocardium. Reducing the AGEs burden and their ensuing pro-inflammatory, pro-oxidative and pro-coagulant effect with associated dysfunctional proteins in various target tissues may retard the progression of and even reverse diabetic macro- and microvascular complications. Pyridinium, 3-[[2-(methylsulfonyl) hydrazino] carbonyl]-1-[2-oxo-2-2-thienyl) ethyl]-chloride (TRC4186) has demonstrated AGE-breaking activities in in vitro experiments and improvement in the endothelial and myocardial function in animal models of diabetes mellitus with reduction of AGEs accumulation in tissues over time.
