Identification of Darunavir Derivatives for Inhibition of SARS-CoV-2 3CL pro. Int J Mol Sci 2022; 23:ijms232416011. [PMID: 36555652 PMCID: PMC9781983 DOI: 10.3390/ijms232416011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2022] [Revised: 11/24/2022] [Accepted: 12/08/2022] [Indexed: 12/23/2022] Open
Abstract
The effective antiviral agents that treat severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are urgently needed around the world. The 3C-like protease (3CLpro) of SARS-CoV-2 plays a pivotal role in virus replication; it also has become an important therapeutic target for the infection of SARS-CoV-2. In this work, we have identified Darunavir derivatives that inhibit the 3CLpro through a high-throughput screening method based on a fluorescence resonance energy transfer (FRET) assay in vitro. We found that the compounds 29# and 50# containing polyphenol and caffeine derivatives as the P2 ligand, respectively, exhibited favorable anti-3CLpro potency with EC50 values of 6.3 μM and 3.5 μM and were shown to bind to SARS-CoV-2 3CLpro in vitro. Moreover, we analyzed the binding mode of the DRV in the 3CLpro through molecular docking. Importantly, 29# and 50# exhibited a similar activity against the protease in Omicron variants. The inhibitory effect of compounds 29# and 50# on the SARS-CoV-2 3CLpro warrants that they are worth being the template to design functionally improved inhibitors for the treatment of COVID-19.

Bioorg Med Chem 2022; 64:116760. [PMID: 35483138 DOI: 10.1016/j.bmc.2022.116760] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2022] [Revised: 04/15/2022] [Accepted: 04/18/2022] [Indexed: 11/30/2022]
Abstract
Based upon the preliminary design of enhancing genetic barrier to drug-resistant viral mutants by maximizing hydrogen-bonding or other van der Waals contacts, we have designed, synthesized and biologically evaluated a new class of HIV-1 protease inhibitors with phenol derived P2 ligands and nitro or halogens in P2' ligands. Results indicate that a majority of inhibitors exhibit robust enzyme inhibitory with IC50 values in picomolar or single digit nanomolar ranges. Among which, compound 17d displays potency with IC50 value of 21 pM and high protease selectivity. Of note, 17d exhibits greater antiviral activity against the DRV-resistant variant than the efficacy against the wild type virus. Furthermore, the molecular modeling studies demonstrate important interactions between 17d and the active sites of both the wild-type and DRV-resistant HIV-1 protease, as well as furnish insights for further optimization of new inhibitors.

Eur J Med Chem 2021; 220:113450. [PMID: 33906049 DOI: 10.1016/j.ejmech.2021.113450] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2020] [Revised: 02/07/2021] [Accepted: 04/03/2021] [Indexed: 01/17/2023]
Abstract
A novel class of HIV-1 protease inhibitors with flexible piperidine as the P2 ligand was designed with the aim of improving extensive interactions with the active subsites. Many inhibitors exhibited good to excellent inhibitory effect on enzymatic activity and viral infectivity. In particular, inhibitor 3a with (R)-piperidine-3-carboxamide as the P2 ligand and 4-methoxybenzenesulfonamide as the P2' ligand showed an enzyme Ki value of 29 pM and antiviral IC50 value of 0.13 nM, more than six-fold enhancement of activity compared to DRV. Furthermore, there was no significant change in potency against DRV-resistant mutations and HIV-1NL4-3 variant for 3a. Besides, inhibitor 3a exhibited potent antiviral activity against subtype C variants with low nanomole EC50 values. In addition, the molecular modeling revealed important hydrogen bonds and other favorable van der Waals interactions with the backbone atoms of the protease and provided insight for designing and optimizing more potent HIV-1 protease inhibitors.
