| | Pinostrobin Usage And Synthesis |
| Description | Pinostrobin is a flavonoid with diverse biological activities, including antioxidant, anti-inflammatory, and anticancer properties. It induces quinone reductase (QR) in murine hepatoma cells with a QR doubling concentration of 500 nM. Pinostrobin inhibits TNF-α and IL-1β production in RAW 264.7 macrophages (IC50s = 17.28 and 23.5 μM, respectively) and in LPS-stimulated rats (48.6 and 55% reduction, respectively). Pinostrobin also shows selective cytotoxicity for CCRF-CEM leukemia cells (IC50 = 10.2 μM) in a panel of eight cancer cell lines (IC50s = >30 μM). | | Uses | Pinostrombin is a useful research chemical that can be used for chemical fingerprinting, isolating, and characterizing of polyphenol compounds. It can also be used as a potential compound for TMPRSS2 inhibition for Covid-19 therapy. | | Definition | ChEBI: A monohydroxyflavanone that is (2S)-flavanone substituted by a hydroxy group at position 5 and a methoxy group at position 7 respectively. | | References | [1] NEERAJ K.
