Introducing pyrimidine bases, the basic components of nucleic acid, to P2 ligands might enhance the potency of Human Immunodeficiency Virus-1 (HIV-1) protease inhibitors because of the carbonyl and amino groups promoting the formation of extensive hydrogen bonding interactions. In this work, we provide evidence that inhibitor 10e, with N-2-(2,4-Dioxo-3,4-dihydropyrimidin-1(2H)-yl) acetamide as the P2 ligand and a 4-methoxylphenylsulfonamide as the P2′ ligand, displayed remarkable enzyme inhibitory and antiviral activity, with the IC50 2.53 nM in vitro and a promising inhibition ratio with 68% against wild-type HIV-1 in vivo, with low cytotoxicity. This inhibitor also exhibited appreciable antiviral activity against DRV-resistant HIV-1 variants, which was of great value for further study.

Since dual inhibitors may yield lower toxicity and reduce the likelihood of drug resistance, as well as inhibitors of HIV-1 PR and RT constitute the core of chemotherapy for AIDS treatment, we herein designed and synthesized new coumarin derivatives characterized by various linkers that exhibited excellent potency against PR and a weak inhibition of RT. Among which, compounds 6f and 7c inhibited PR with IC50 values of 15.5 and 62.1 nM, respectively, and weakly affected also RT with IC50 values of 241.8 and 188.7 μM, respectively, showing the possibility in the future of developing dual HIV-1 PR/RT inhibitors. Creative stimulation for further research of more potent dual HIV-1 inhibitors was got according to the molecular docking studies.

We have discovered a potent low molecular weight series of HIV-1 protease inhibitors incorporating the (R)-(hydroxyethyl) sulfonamide isostere.

Upon the basis of both possible ligand-binding site interactions and the uniformity of key residues in active sites, a novel class of HIV-1 PR/RT dual inhibitors was designed and evaluated. Cinnamic acids or phenylpropionic acids with more flexible chain and smaller steric hindrance were introduced into the inhibitors, giving rise to significant improvement in HIV-1 RT inhibitory activity by one or two orders of magnitude, with comparable or even improved potency against PR at the same time, compared with coumarin anologues in our previous studies. Among these inhibitors, 38d displayed a 19-fold improvement in anti-PR activity with IC50 value of 0.081 nM compared to the control DRV. In addition, inhibitor 38c exhibited an excellent anti-RT IC50 value of 0.43 μM, only a 4.7-fold less potent activity than the control EFV. More significantly, the disparate ratio between HIV-1 PR and RT inhibition became more reasonable with ratio of 1: 10.4, just as 37b. Furthermore, the assays on HIV-1 late stage and early stage supported the rationality of designing dual inhibitors. The SAR data as well as molecular modeling studies provided new insight for further optimization of more potent HIV-1 PR/RT dual inhibitors.
