trans-Resveratrol is a polyphenol that has been found in grapes and has diverse biological activities.^1,2 It inhibits the cyclooxygenase and hydroperoxidase activities of COX-1 (EC50s = 15 and 3.7 μM, respectively) but not COX-2 (EC50s = >100 μM and 85 μM, respectively).¹ trans-Resveratrol (200 μM) also activates sirtuin 1 (SIRT1), as well as inhibits a variety of targets including ERK1, JNK1, Src, PKCα, aromatase/CYP19, and DNA polymerases α and δ (IC50s = 37, 50, 20, <10, 25, 3.3, and 5 μM, respectively) in vitro.^3,2 It inhibits free radical formation induced by phorbol 12-myristate 13-acetate (TPA) in HL-60 cells and reduces the tumor incidence and number of tumors in a two-stage mouse model of skin cancer induced by TPA and 7,12-dimethyl-benz[a]anthracene (DMBA). trans-Resveratrol (3 and 8 mg/kg) inhibits carrageenan-induced paw edema in mice. Intravaginal administration of trans-resveratrol (12.5% v/v) inhibits herpes simplex virus 1 (HSV-1) and HSV-2 replication and delays the development of extravaginal disease in mouse models of vaginal HSV infection.⁴ It also prolongs lifespan in model organisms including C. elegans, D. melanogaster, and mice.²
