Description: Bevirimat, also known as MPC-4326 and PA-457, is an anti-HIV drug derived from a betulinic acid-like compound, first isolated from Syzygium claviflorum, a Chinese herb. It is believed to inhibit HIV by a novel mechanism, so-called maturation inhibition. Like protease inhibitors, bevirimat and other maturation inhibitors interfere with protease processing of newly translated HIV polyprotein precursor, called gag. Bevirimat prevents this viral replication by specifically inhibiting cleavage of the capsid protein (CA) from the SP1 spacer protein.
