Opis:
Coronavirus disease 2019 caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has affected 235.6 million people worldwide. In the present study, RNA-dependent RNA polymerase (RdRp) (PDB Id: 6M71) of SARS-CoV-2, an essential enzyme needed for subgenomic replication and amplification of RNA, was selected. Similar to other RdRps, it is a conserved protein and a popular target for antiviral drug therapy. Based on a computational approach, potential RdRp inhibitors were identified. The absorption, distribution, metabolism, excretion, and toxicity (ADMET) of selected molecules were determined using computation tools. The potential inhibitors were docked to the RdRp and later confirmed by Molecular Dynamics (MD) using the “Flare” module of Cresset software. Drummondin E and Flinderole B had higher drug similarity scores among the compounds selected in this study. Both these compounds are noncarcinogenic, nonirritant, nontumorigenic, and nonmutagenic. Molecular docking studies showed that both compounds can bind to RdRp. The best ligand interaction patterns were validated by MD using the “Flare” module. MD was performed for the period of 100 ns with the time step of 1 fs. The simulation results suggest that Thr-680, Arg-624, Lys-676, and Val-557 are key interacting partners in the Drummondin E-RdRp complex, while Asp-618, Asp-760, Asp-623, Arg-624, and Asp-761 are the interacting partners in the Flinderole B-RdRp complex. Based on the in silico drug-likeness score; ADMET properties; and molecular simulation result, we surmise that Flinderole B and Drummondin E could impede SARS-CoV-2 genome replication and transcription by targeting the RdRp protein.

Opis:
Candida auris is a major public health concern due to its high transmission and mortality rates, as well as the emergence of pan-resistant strains. This study aimed to identify an antifungal compound from Sarcochlamys pulcherrima , an ethnomedicinal plant, that can inhibit the growth of C. auris. Methanol and ethyl acetate extracts of the plant were obtained, and high-performance thin-layer chromatography (HPTLC) analysis was conducted to identify the major compounds in the extracts. The major compound detected by HPTLC was subjected to in vitro antifungal activity testing, and its antifungal mechanism was determined. The plant extracts inhibited the growth of both C. auris and Candida albicans. HPTLC analysis revealed the presence of gallic acid in the leaf extract. Furthermore, the in vitro antifungal assay showed that gallic acid inhibited the growth of different C. auris strains. In silico studies indicated that gallic acid can bind to the active sites of carbonic anhydrase (CA) proteins in both C. auris and C. albicans, affecting their catalytic activities. Compounds that target virulent proteins such as CA can aid in the reduction of drug-resistant fungi and the development of novel antifungal compounds with unique modes of action. However, additional in vivo and clinical studies are required to conclusively determine gallic acid’s antifungal properties. Gallic acid derivatives may be developed in the future to possess more potent antifungal properties and target various pathogenic fungi.
