Caraphel A

Caraphenol A is a resveratrol trimer and is able to transiently reduce interferon-induced transmembrane (IFITM) protein expression. Caraphenol A safely enhances lentiviral vector gene delivery to hematopoietic stem and progenitor cells[1]. Caraphenol A also inhibits human cystathionine β-synthase (hCBS) and human cystathionine γ- lyase (hCSE) with IC50s of 5.9 μM and 12.1 μM, respectively[2].
