Despite the effectiveness of currently available human immunodeficiency virus type 1 (HIV-1) therapies, a continuing need exists for new drugs to treat HIV-1 infection. We investigated the mechanism by which 3-O-[3',3'-dimethylsuccinyl]-betulinic acid (DSB) inhibits HIV-1 replication. DSB functions at a late stage of the virus life cycle but does not(More)
BACKGROUND Despite the effectiveness of currently available antiretroviral therapies in the treatment of HIV-1 infection, a continuing need exists for novel compounds that can be used in combination with existing drugs to slow the emergence of drug-resistant viruses. We previously reported that the small molecule 3-O-{3',3'-dimethylsuccinyl}-betulinic acid(More)
Monoamine oxidase (MAO) A and B are important enzymes that metabolize biogenic amines throughout the body. Previous studies had suggested that both MAO A and B consist of two subunits of molecular masses of 63 and 60 kilodaltons, respectively. The cDNAs encoding one subunit of human liver MAO A and B have been expressed in mammalian cells by transfection of(More)
