Synthesis and Cardiotropic Activity of Linear Methoxyphenyltriazaalkanes

A new group of potential pFOX inhibitors among linear methoxyphenyltriazaalkanes were designed and synthesized. Cardiotropic activity in rodent experiments was found for most of the synthesized compounds. The most active compound N 1 -(2,3,4-trimethoxybenzyl)-N 2 -{2-[(2,3,4-trimethoxybenzyl)amino]ethyl}-1,2-ethanediamine trihydrochloride (LM-1) combined anti-ischemic, antiarrhythmic, and antifibrillatory activities (1 mg/kg, i.v.) and low toxicity (LD 50 = 119 mg/kg, mice, i.p.) and was selected for development as a potential cardiotropic drug.
