RNA processing plays a key role in gene expression, allowing for increased protein diversity and functional complexity. Consequently, modulating RNA processing can impact gene function. Given HIV-1's reliance on host RNA processing machinery for viral protein production/replication, modulators of this process could serve as novel anti-virals to complement and/or enhance existing therapies. In this study, screening of several serine-arginine-rich (SR) kinase inhibitors for their impact on HIV-1 gene expression identified harmine as an inhibitor of HIV-1 gene expression in several cell lines and primary CD4+ T cells/macrophages at low micromolar concentrations with limited cell toxicity...
