MuDRA-Based Virtual Screening of Terpenes for Anti-Leishmania Infantum Activity: In Vitro Validation and Mechanistic Insights from Molecular Docking.

Leishmaniasis, caused by Leishmania parasites, presents a major global health challenge due to limitations of existing treatments, including toxicity, side effects, drug resistance, and high costs. This study utilized the MuDRA (Multi-Descriptor Read Across) model for virtual screening to identify potential anti-Leishmania infantum compounds. A set of 15 terpenes and steroids was screened, leading to the identification of four promising candidates-lupeol, xylodiol, morolic acid, and trachyloban-18-oic acid.

Cytotoxic and Antileishmanial Effects of the Monoterpene β-Ocimene.

Leishmaniasis is a group of infectious-parasitic diseases with high mortality rates, and endemic in many regions of the globe. The currently available drugs present serious problems such as high toxicity, costs, and the emergence of drug resistance. This has stimulated research into new antileishmania drugs based on natural products and their derivatives.

Alterations of the male and female reproductive systems induced by COVID-19.

A variety of pneumonia cases of unknown cause emerged in China in December 2019. A new virus belonging to the Coronaviridae family, called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes coronavirus disease 2019 (COVID-19). Within a few days, COVID-19 became a pandemic disease.
