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)
Oligomeric N-methyl D-aspartate receptor (NMDAR) in brain is a ligand-gated ion channel that becomes selectively permeable to ions upon binding to ligands. For NMDAR channel, the binding of glutamate and glycine results in opening of the calcium permeable channel. Because the calcium influx mediated by NMDAR is important for synaptic plasticity and(More)
