Antiviral Activity of Cholesteryl Esters of Cinnamic Acid Derivatives

Zeitschrift für Naturforschung C, 1998
Cholesteryl 3”,4”-dimethoxycinnamate (7) and a new synthesized o-coumaroyl ester of 3β- (2’-hydroxyethoxy)-cholest-5-en (13) exhibited a marked activity against poliovirus type 1 (Mahoney). Compound 7 showed an approximately 20-fold greater selectivity in its antiviral activity than compound 13. These compounds were selected from thirteen steryl esters
