Abstract

HIV-1 non-nucleoside Reverse Transcriptase inhibitors (NNRTIs) play a crucial role in combination antiretroviral therapy (cART). To further enhance their Antiviral activity and anti-resistance properties, we developed a series of novel NNRTIs, by specifically targeting tolerant region I of the NNRTI binding pocket. Among them, compound 9t-2 displayed excellent anti-HIV-1 potency against wild-type and prevalent mutant strains with EC50 values between 0.0019 and 0.012 μM. This outperformed the positive drugs ETR, NVP and RPV. Aslo, ELISA results confirmed that these compounds can effectively inhibit the activity of HIV-1 RT. Molecular dynamics (MD) simulation studies indicated that the thiomorpholine-1,1-dioxide moiety of 9t-2 is capable of establishing additional interactions with residues P225, F227 and P236 in the tolerant region I, which contributed to its enhanced activity. Compound 9t-2 possessed negligible inhibitory effect on the five main CYP isoenzymes (IC50 > 10 μM), indicating a low potential for inducing CYP-mediated drug-drug interactions. In conclusion, compound 9t-2, with its enhanced anti-resistance properties, stands out as a promising lead compound for further optimization towards discovering the new generation of anti-HIV agents.
