PD-404182 is an inhibitor of bacterial 2-keto-3-deoxyctulosonic acid (KDO) 8-P synthase. It is a virucidal compound that compromises the structural integrity of both hepatitis C virus and human immunodeficiency virus, likely by interacting with a nonlipid structural element of these viruses. In vitro studies revealed that PD-404182 physically disrupts variously pseudotyped lentiviruses and exposes the viral genomic RNA in a time- and temperature-dependent manner. Also, PD-404182 might be a tightly bound, covalent, or an irreversible inhibitor of human dimethylarginine dimethylaminohydrolase 1.

Route of Administration: Unknown
Anti-human immunodeficiency virus (HIV)-1 50% inhibitory concentration (IC50) of PD-404182, when diluted in seminal plasma, is ∼1 uM, is similar to the IC50 determined in cell culture growth medium, also PD-404182 retains full anti-HIV-1 activity after incubation in the cervical fluid at 37°C for at least 24 h. In addition, PD-404182 is nontoxic toward vaginal commensal Lactobacillus species (50% cytotoxic concentration [CC50] >300 uM), freshly activated human peripheral blood mononuclear cells (CC50 ∼200 uM), and primary CD4(+) T cells, macrophages, and dendritic cells (CC50 >300 μM).
