The Malaria Box molecules: a source for targeting the RBD and NTD cryptic pocket of the spike glycoprotein in SARS-CoV-2.

Context: SARS-CoV-2, responsible for COVID-19, has led to over 500 million infections and more than 6 million deaths globally. There have been limited effective treatments available. The study aims to find a drug that can prevent the virus from entering host cells by targeting specific sites on the virus's spike protein.

study revealed the inhibitory activity of selected phytomolecules of against VacA implicated in gastric ulcer.

Gastric ulcer is associated with weakening of the mucous coating of the stomach and damages to the intestinal lining. It is caused by assisted by enzymes including VacA, which necessitates the need for inhibitors of VacA. Bioactive compounds from have been documented to have anti-inflammatory activities.

Glycosylation is key for enhancing drug recognition into spike glycoprotein of SARS-CoV-2.

The emergence of COVID-19 caused by SARS-CoV-2 and its spread since 2019 represents the major public health problem worldwide nowadays, which has generated a high number of infections and deaths. The spike protein (S protein) is the most studied protein of SARS-CoV-2, and key to host-cell entry through ACE2 receptor. This protein presents a large pattern of glycosylations with important roles in immunity and infection mechanisms.

Novel multi-epitope protein containing conserved epitopes from different Leishmania species as potential vaccine candidate: Integrated immunoinformatics and molecular dynamics approach.

Leishmaniosis, caused by intracellular parasites of the genus Leishmania, has become a serious public health problem around the world, and for which there are currently extensive limitations. In this work, a theoretical model was proposed for the development of a multi-epitope vaccine. The protein GP63 of the parasite was selected for epitopes prediction, due to its important biological role for the infection process and abundance.

Potential novel inhibitors against emerging zoonotic pathogen : a virtual screening and molecular dynamics approach.

Nipah virus is a pathogen considered highly infectious, and its lethality can cause between 40% and 70% of deaths in those infected. At present, no effective treatment is available which results in an imperative need to explore new approaches to the search for drugs. Through virtual screening techniques, docking and molecular dynamics, 183 ligands were evaluated against the Nipah virus glycoprotein (NiV-G), involved throughout the process of virus entry to the host cell, resulting in a good target for blocking the infection.
