A persistent latent reservoir of virus in CD4+ T cells is a major barrier to cure HIV. Activating viral transcription in latently infected cells using small molecules is one strategy being explored to eliminate latency. We previously described the use of a FlpIn.FM HEK293 cellular assay to identify and then optimize the 2-acylaminothiazole class to exhibit modest activation of HIV gene expression. Here, we implement two strategies to further improve the activation of viral gene expression and physicochemical properties of this class. Firstly, we explored rigidification of the central oxy-carbon linker with a variety of saturated heterocycles, and secondly, investigated bioisosteric replacement of the 2-acylaminothiazole moiety. The optimization process afforded lead compounds (74 and 91) from the 2-piperazinyl thiazolyl urea and the imidazopyridine class. The lead compounds from each class demonstrate potent activation of HIV gene expression in the FlpIn.FM HEK293 cellular assay (both with LTR EC50s of 80 nM) and in the Jurkat Latency 10.6 cell model (LTR EC50 220 and 320 nM respectively), but consequently activate gene expression non-specifically in the FlpIn.FM HEK293 cellular assay (CMV EC50 70 and 270 nM respectively) manifesting in cellular cytotoxicity. The lead compounds have potential for further development as novel latency reversing agents.

The persistent reservoir of cells latently infected with human immunodeficiency virus (HIV)-integrated proviral DNA necessitates lifelong suppressive antiretroviral therapy (ART). Epigenetic targeted compounds have shown promise as potential latency-reversing agents; however, these drugs have undesirable toxicity and lack specificity for HIV. We utilized a novel HEK293-derived FlpIn dual-reporter cell line, which quantifies specific HIV provirus reactivation (LTR promoter) relative to nonspecific host cell gene expression (CMV promoter), to identify the 5-substituted 2-acylaminothiazole hit class. Here, we describe the optimization of the hit class, defining the functionality necessary for HIV gene activation and for improving in vitro metabolism and solubility. The optimized compounds displayed enhanced HIV gene expression in HEK293 and Jurkat 10.6 latency cellular models and increased unspliced HIV RNA in resting CD4+ T cells isolated from HIV-infected individuals on ART, demonstrating the potential of the 2-acylaminothiazole class as latency-reversing agents.
