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.

Due to the arising resistance of common drugs targeting the Hedgehog signaling pathway, the identification of new compound classes with inhibitory effect is urgently needed. We were able to identify S-alkylated 2-mercaptobenzoimidazoles as a new compound

A compound of the formula EQU1 or an acid addition salt thereof wherein R1 and R2 are the same or different and each is a phenyl or thien-2-yl group optionally substituted in one or more positions by a substituent selected from the class consisting of halogen, lower alkyl, lower alkoxy, hydroxy, lower alkylthio, phenyl, phenoxy, phenyl-(lower-alkyl) and phenyl-(lower-alkoxy), each of the said phenyl, phenoxy, phenyl-(lower-alkyl) and phenyl-(lower-alkoxy) substituent groups being optionally substituted in one or more positions by a member selected from the class consisting of halogen, lower alkyl, lower alkoxy, hydroxy, and lower alkylthio; A1 is a divalent straight or branched alkylene group containing from two to six carbon atoms and one or two divalent atoms which are each an oxygen or sulphur atom, provided that there are at least two carbon atoms between the divalent atom and the --NH-- group and between the two divalent atoms; and A2 is the methylene group --CH2 --.
