Pyrrothiogatain
Based on 1 publication(s) in Google Scholar
Pyrrothiogatain is a transcription factor GATA3 inhibitor with an IC50 of 54.7 μM. Pyrrothiogatain inhibits the DNA-binding activity of GATA3 and inhibits the T helper 2 (Th2) cell differentiation and expression of Th2 cytokines. Pyrrothiogatain shows anti-infection effect by inhibiting ACE2 expression. Pyrrothiogatain can be used for the researches of inflammation, immunology, infection and cancer, such as colon cancer and SARS-CoV-2 infection.
