Negative inotropic and calcium antagonistic activity of alkyl and arylalkyl phosphonates

Farmaco. 1989 Dec;44(12):1167-91.

Abstract

Several alkyl and arylalkyl diethylphosphonates related to fostedil have been synthetized and tested for negative inotropic activity (isolated guinea pig left atrium) and Ca++ antagonistic activity (isolated guinea pig aortic strips). The results show that negative inotropic and Ca++ antagonistic activity might depend from different molecular features.
