Biochem/physiol Actions

Reversible: no

Product does not compete with ATP.

Primary TargetCOX-1 and COX-2 activities

Cell permeable: yes

Target IC₅₀: 19.8 µM, 83.9 µM against COX-1 and -2 activities, respectively; 70 µM for inducing apoptosis in HL60 cells; ED50 = 4.8 µM for preventing DMBA-induced preneoplastic lesions

General description

A cell-permeable methoxylated analog of Resveratrol (Cat. No. 554325) that displays antioxidant, antiproliferative, and hypoglycemic properties. Moderately inhibits COX-1 and -2 activities (IC₅₀ = 19.8 µM and 83.9 µM) respectively, induces apoptosis in HL60 cells (IC₅₀ = 70 µM), prevents DMBA-induced preneoplastic lesions (ED₅₀ = 4.8 µM) and decreases plasma glucose level in streptozotocin-induced diabetic rats comparable to that of Metformin.

A cell-permeable methoxylated analog of Resveratrol (Cat. No. 554325) that displays antioxidant, anti-proliferative, and hypoglycemic properties. Appears to be a better free radical scavenger than Trolox (Cat. No. 64847). Moderately inhibits COX-1 & COX-2 activities (IC₅₀ = 19.8 µM & 83.9 µM, respectively) and induces apoptosis in HL60 cells (IC₅₀ = 70 µM). Also prevents DMBA-induced pre-neoplastic lesions (ED₅₀ = 4.8 µM). Reported to decrease plasma glucose levels in streptozotocin-induced diabetic rats comparable to that of Metformin.
