The persistence of HIV-1 latent reservoir creates the major obstacle toward an HIV-1 cure. The “shock and kill” strategy aims to reverse HIV-1 proviral latency using latency-reversing agents (LRAs), thus boosting immune recognition and clearance to residual infected cells. Unfortunately, to date, none of these tested LRA candidates has been demonstrated effectiveness and/or safety in reactivation HIV-1 latency. The discovery and development of effective, safe and affordable LRA candidates are urgently needed for creating an HIV-1 functional cure. Here, we designed and synthesized a series of small-molecule phenoxyacetic acid derivatives based on the resveratrol scaffold and found one of them, named 5, 7-dimethoxy-2-(5-(methoxymethyl) furan-2-yl) quinazolin-4(3H)-one (Q205), effectively reactivated latent HIV-1 in latent HIV-1-infected cells without a corresponding increase in induction of potentially damaging cytokines. The molecular mechanism of Q205 is shown to increase the phosphorylation of the CDK9 T-loop at position Thr186, dissociate positive transcription elongation factor b (P-TEFb) from BRD4, and promote the Tat-mediated HIV-1 transcription and RNA polymerase II (RNAPII) C-terminal domain (CTD) on Ser (CTD-Ser2P) to bind to the HIV-1 promoter. This study provides a unique insight into resveratrol modified derivatives as promising leads for preclinical LRAs, which in turn may help toward inhibitor design and chemical optimization for improving HIV-1 shock-and kill-based efforts.

We have developed novel orally active quinazoline analogues as inhibitors of AP-1 and NF-κB mediated transcriptional activation. Among the derivatives prepared, 1-[2-(2-thienyl)quinazolin-4-ylamino]-3-methyl-3- pyrroline-2,5-dione (10) showed significant activity in an adjuvant-induced arthritis rat model by reducing the swelling by 65% in the non-injected foot. The synthesis, structure-activity relationship, and in vivo activity are described.
