Verapamil inhibits respiratory syncytial virus infection by regulating Ca 2+ influx. Life Sci 2024; 352:122877. [PMID: 38942358 DOI: 10.1016/j.lfs.2024.122877] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2024] [Revised: 06/24/2024] [Accepted: 06/25/2024] [Indexed: 06/30/2024]
Abstract
AIMS The study evaluated the antiviral effect of Verapamil against respiratory syncytial virus (RSV) and investigated its underlying mechanism. MATERIALS AND METHODS RSV-infected BALB/c mice were treated with Verapamil. Body weight, survival rates, viral load, lung damage, inflammatory factors, and the expression of RSV fusion (F) protein were analyzed. In cellular studies, intracellular Ca2+ and viral titers were measured in the presence of Verapamil, Calcium Chloride, and EGTA. A time-of-addition assay assessed the antiviral effect of Verapamil. KEY FINDINGS Mice infected with RSV and treated with Verapamil exhibited a significant decrease in weight loss, an increase in survival rates, and reductions in viral titers, RSV F protein expression, inflammatory responses, and lung tissue injury. Verapamil reduced intracellular calcium levels, which correlated with reduced viral titers. The addition of calcium chloride reversed the anti-viral effects mediated by Verapamil, while EGTA potentiated them. The antiviral activity of Verapamil was observed during the early phase of RSV infection, likely by blocking Ca2+ channels and inhibiting virus replication. SIGNIFICANCE Verapamil effectively inhibits RSV infection by blocking calcium channels and reducing intracellular calcium levels, thereby impeding viral replication. Thus, Verapamil shows promise as a treatment for RSV.

Abstract
Because of the hydrophobic nature of the membrane lipid bilayer, the majority of the hydrophilic solutes require special transportation mechanisms for passing through the cell membrane. Integral membrane transport proteins (MTPs), which belong to the Major Intrinsic Protein Family, facilitate the transport of these solutes across cell membranes. MTPs including aquaporins and carrier proteins are transmembrane proteins spanning across the cell membrane. The easy handling of microorganisms enabled the discovery of a remarkable number of transport proteins specific to different substances. It has been realized that these transporters have very important roles in the survival of microorganisms, their pathogenesis, and antimicrobial resistance. Astonishing features related to the solute specificity of these proteins have led to the acceleration of the research on the discovery of their properties and the development of innovative products in which these unique properties are used or imitated. Studies on microbial MTPs range from the discovery and characterization of a novel transporter protein to the mining and screening of them in a large transporter library for particular functions, from simulations and modeling of specific transporters to the preparation of biomimetic synthetic materials for different purposes such as biosensors or filtration membranes. This review presents recent discoveries on microbial membrane transport proteins and focuses especially on formate nitrite transport proteins and aquaporins, and advances in their biotechnological applications.

Abstract
A series of dye ligands are docked to three different proteins, E and 3a of severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) and E6 of human papilloma virus type 16 (HPV-16) using three different software. A four-level selection algorithm is used based on nonparametric statistics of numerical key values such as the "rank" derived from (i) averaged estimated binding energies (EBEs) and (ii) absolute EBE value of each of the software, (iii) frequency of ranking and (iv) rank of the area-under-curve values (AUCs) from decoy docking. A series of repurposing drugs and known antivirals used in experimental studies are docked for comparison. One dye ligand is ranked best for all proteins using the selection algorithm levels i - iii. Another three dye ligands are ranked top for the proteins individually when using all four levels.

Searching for Blockers of Dengue and West Nile Virus Viroporins. Viruses 2022; 14:v14081750. [PMID: 36016372 PMCID: PMC9413451 DOI: 10.3390/v14081750] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2022] [Revised: 08/02/2022] [Accepted: 08/09/2022] [Indexed: 11/19/2022] Open
Abstract
Flavivirus infections, such as those caused by dengue and West Nile viruses, emerge as new challenges for the global healthcare sector. It has been found that these two viruses encode ion channels collectively termed viroporins. Therefore, drug molecules that block such ion-channel activity can serve as potential antiviral agents and may play a primary role in therapeutic purposes. We screened 2839 FDA-approved drugs and compounds in advanced experimental phases using three bacteria-based channel assays to identify such ion channel blockers. We primarily followed a negative genetic screen in which the channel is harmful to the bacteria due to excessive membrane permeabilization that can be relieved by a blocker. Subsequently, we cross-checked the outcome with a positive genetic screen and a pH-dependent assay. The following drugs exhibited potential blocker activities: plerixafor, streptomycin, tranexamic acid, CI-1040, glecaprevir, kasugamycin, and mesna were effective against dengue virus DP1. In contrast, idasanutlin, benzbromarone, 5-azacytidine, and plerixafor were effective against West Nile Virus MgM. These drugs can serve as future antiviral therapeutic agents following subsequent in vitro and in vivo efficacy studies.
