Biological target: RO-0335 is a novel diphenylether nonnucleoside reverse transcriptase inhibitor.
In vitro activity: To study potential pathways leading to resistance against the novel diphenylether NNRTI, RO-0335, sequential passage experiments at low multiplicity of infection (MOI) were performed to solicit a stepwise selection of resistance mutations. Two pathways to loss of susceptibility to RO-0335 were observed, containing patterns of amino acid changes at either V106I/A plus F227C (with additional contributions from A98G, V108I, E138K, M230L and P236L) or V106I/Y188L (with a potential contribution from L100I, E138K and Y181C). Characterization of the observed mutations by site-directed mutagenesis in the isogenic HXB2D background demonstrated that a minimum of two or more mutations were required for significant loss of susceptibility, with the exception of Y188L, which requires a two-nucleotide change. Patterns containing F227C or quadruple mutations selected by RO-0335 showed a low relative fitness value when compared to wild-type HXB2D.
