Piceatannol

CAS No.: 10083-24-6

Piceatannol, a well-known Syk inhibitor, reduces TNF-induced iNOS expression and is effective in acute lung injury (ALI) research. This naturally occurring polyphenolic stilbene, found in various fruits and vegetables, exhibits anticancer and anti-inflammatory properties, induces apoptosis in DLBCL cell lines, and promotes autophagy and apoptosis in MOLT-4 human leukemia cells.

Synonyms: Astringenin; trans-Piceatannol; NSC 622471

Abstract: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has forced the development of direct-acting antiviral drugs due to the coronavirus disease 2019 (COVID-19) pandemic. The main protease of SARS-CoV-2 is a crucial enzyme that breaks down polyproteins synthesized from the viral RNA, making it a validated target for the development of SARS-CoV-2 therapeutics. New chem. phenotypes are frequently discovered in natural goods. In the current study, we used a fluorogenic assay to test a variety of natural products for their ability to inhibit SARS-CoV-2 Mpro. Several compounds were discovered to inhibit Mpro at low micromolar concentrations It was possible to crystallize robinetin together with SARS-CoV-2 Mpro, and the X-ray structure revealed covalent interaction with the protease's catalytic Cys145 site. Selected potent mols. also exhibited antiviral properties without cytotoxicity. Some of these powerful inhibitors might be utilized as lead compounds for future COVID-19 research.
