Oxidative stress is one of the major causative factors of many chronic and degenerative diseases. Plants have been used in traditional medicine in different parts of world for thousands of years and continue to provide new remedies for human kind. The present study was to investigate the preliminary phytochemical analysis of various extracts of roots and leaves of Trewia nudiflora (Euphorbiaceae) and antioxidant activity by 1,1,diphenyl-2-picryl hydrazyl (DPPH) radical scavenging method. The preliminary phytochemical screening showed the presence of several phytochemicals including alkaloids, glycosides, flavonoids, steroids, phenolic compounds and tannins. The ethanol and aqueous extracts of roots and leaves of Trewia nudiflora showed significant antioxidant activity compared to standard drug ascorbic acid.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
