[Study of the mechanism of action of novel fluoro-containing analogs of diazoxide on the vascular tonus]

Abstract

On the isolated preparations of rat aorta it was shown that the new fluoro-containing analogues of diazoxide (DiazoFp and DiazoFm) elicit vasodilatatory effects related to the activation of ATP-sensitive potassium channels. It was established that DiazoFp is a more powerful vasodilator than DiazoFm and diazoxide. It was proposed that DiazoFp action consists of two components: direct activation of sarcKATP channels and activation of sarcKATP channels, through activation of mitoKATP channels.
