Design and biological evaluation of cinnamic and phenylpropionic amide derivatives as novel dual inhibitors of HIV-1 protease and reverse transcriptase. Eur J Med Chem 2021; 220:113498. [PMID: 33933756 DOI: 10.1016/j.ejmech.2021.113498] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2020] [Revised: 04/15/2021] [Accepted: 04/17/2021] [Indexed: 01/16/2023]
Abstract
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.

Design, synthesis and biological evaluation of HIV-1 protease inhibitors with morpholine derivatives as P2 ligands in combination with cyclopropyl as P1' ligand. Bioorg Med Chem Lett 2020; 30:127019.

Abstract
A series of novel HIV-1 protease inhibitors has been designed and synthesized, which contained morpholine derivatives as the P2 ligands and hydrophobic cyclopropyl as the P1' ligand at the meantime in this study, with the aim of improving the interactions between the active sites of HIV-1 protease and the inhibitors. Twenty-eight compounds were synthesized and assessed, among which inhibitors m18 and m1 exhibited excellent inhibitory effect on the activity of HIV-1 protease with IC50 value of 47 nM and 53 nM, respectively. The molecular modeling of m1 revealed possible hydrogen bondings or van der Waals between the inhibitor and the protease, worthy of in-depth study.

Abstract
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.

Abstract
The HIV-1 life cycle consists of different events, such as cell entry and fusion, virus replication, assembly and release of the newly formed virions. The more logical way to inhibit HIV transmission among individuals is to inhibit its entry into the immune host cells rather than targeting the intracellular viral enzymes. Both viral and host cell surface receptors and co-receptors are regarded as potential targets in anti-HIV-1 drug design process. Because of the importance of this topic it was decided to summarize recent reports on small-molecule HIV-1 entry inhibitors that have not been considered in the latest released reviews. All the computational studies reported in the literature regarding HIV-1 entry inhibitors since 2014 was also considered in this review.

Abstract
GPCRs play a pervasive physiological role and, in turn, are the leading target class for pharmaceuticals. Beginning with the determination of the structure of rhodopsin, and dramatically accelerating since the reporting of the first ligand-mediated GPCR X-ray structures, our understanding of the structural and functional characteristics of these proteins has grown dramatically. Deploying this now rapidly emerging information for drug discovery has already been extensively demonstrated through a watershed of studies appearing in numerous scientific reports. Included in these expositions are areas such as sites and characteristics of ligand to GPCR binding, protein activation, effector bias, allosteric mechanisms, dimerization, polypharmacology and others. Computational chemistry studies are demonstrating an increasing role in capitalizing on the structural studies to further advance our understanding of these proteins as well as to drive drug discovery. Such drug discovery activities range from the design of orthosteric site inhibitors through, for example, allosteric modulators, biased ligands, partial agonists and bitopic ligands. Herein, these topics are outlined through specific examples in the hopes of providing a glimpse of the state of the field.
