The long-lived latent HIV-1 reservoir is the major barrier for complete cure of Acquired Immune Deficiency Syndrome (AIDS). Here we report that a novel bromodomain and extraterminal domain (BET) inhibitor bromosporine which can broadly target BETs, is able to potently reactivate HIV-1 replication in different latency models alone and more powerful when combined with prostratin or TNF-α. Furthermore, the treatment with bromosporine induced HIV-1 full-length transcripts in resting CD4+ T cells from infected individuals with suppressive antiretroviral therapy (ART) ex vivo, with no obvious cytotoxicity or global activation of T cell. Finally, our data suggest that Tat plays a critical role in the bromosporine-mediated reactivation of latent HIV-1, which involved the increase of CDK9 T-loop phosphorylation. In summary, we found that the BET inhibitor bromosporine, alone or with other activators, might be a candidate for future HIV-1 eradication strategies.
