Background
Bromosporine is a potent broad-spectrum bromodomain inhibitor (1). Bromodomain and extra-terminal (BET) protein family members BRD2, BRD3, BRD4, and BRDT associate with acetylated lysines on histones and transcription factors to regulate their function, and have emerged as targets for cancer therapy (2,3). Treatment with Bromosporine induced the expression of latent HIV-1 in primary CD4 T cells by inhibiting BET activity, leading to improved viral clearance in conjunction with antiretroviral therapy (4).
Alternate Names
