Ethyl salvianolate A (Ethyl salvionolate A) is an anti-HIV-1 compound that can be extracted from the roots of Salvia yunnanensis. Ethyl salvianolate A inhibits P24 antigen in HIV-1 infected MT-4 cell cultures (EC50: 1.44 µg/mL). Ethyl salvianolate A inhibits HIV-1 replicative enzymes, with IC50s of 56.38 µM (Reverse transcriptase), 12.03 µM (Protease), 14.54 µM (Integrase), respectively[1].
