Abstract

The world is witnessing severe health meltdown due to COVID-19. Generic antiviral drug remdesivir has been found to reduce time to clinical recovery but with insignificant clinical benefits and the antimalarial drug, hydroxychloroquine has been red flagged by USFDA for use as a prophylactic measure due to its cardiotoxicity. There is an acute requirement for a drug candidate that has significant clinical benefit with minimal to no side effects. With restricted access to wet laboratory techniques, an alternative approach is to engage in computational screening of lead molecules that could inhibit SARS-CoV-2 at different stages of its infectious cycle. Several in silico studies on natural derivatives, especially that present in daily refreshments (tea and fruit juices), staple food (black rice, red onions, soy beans etc) and traditional medicines (extracts of herbs, leaves and flowers) have been identified as potential drug candidates that bind efficiently with the key viral proteins. However, oral bioavailability of these nutriments is considerably low due to either poor permeability or loss of structure and function due to digestion in the gastrointestinal tract. Here we discuss few natural secondary metabolites (Delphinidin 3,...Continue Reading

Cardiotoxicity

Cardiotoxicity refers to the muscle damage or dysfunction of heart electrophysiology caused by drug intake or due to disease complications. It is a well-known side effect of several cytotoxic drugs, especially of the anthracyclines and can lead to long term morbidity. Here is the latest research.
