Preclinical virology profiles of the HIV-1 capsid inhibitors VH4004280 and VH4011499.

ABSTRACT: With its high degree of conservation and critical role in multiple steps of the HIV-1 life cycle, the HIV-1 capsid protein presents an attractive therapeutic target. Herein, the virologic properties of the HIV-1 capsid inhibitors VH4004280 (VH-280) and VH4011499 (VH-499), including potency, mechanisms of action, and resistance profiles, are described. VH-280 and VH-499 inhibited panels of HIV-1 laboratory strains and viruses containing capsid sequences from clinical isolates with half-maximal effective concentrations in the picomolar range. Time-of-addition experiments determined that the primary block to HIV-1 replication occurred after nuclear import and before integration; however, measurements of replication intermediates by quantitative polymerase chain reaction, Gag degradation, p24
