4-Allylcatechol is a phenol that has been found in P. betle and has diverse biological activities.1,2,3,4 It scavenges DPPH (Item No. 14805) radicals, reduces the formation of thiobarbituric acid reactive substances (TBARS), and inhibits xanthine oxidase in cell-free assays (IC50s = 20.17, 2, and 16.7 µM, respectively).1,2 4-Allylcatechol is cytotoxic to HT-29 colon cancer cells (IC50 = 30 µg/ml).3 It reduces paw edema and arthritic paw tissue homogenate levels of IL-1β, prostaglandin E2 (PGE2; Item No. 14010), leukotriene B4 (LTB4; Item No. 20110), and nitric oxide (NO) in a mouse model of steam-killed M. tuberculosis-induced arthritis when administered at a dose of 4 mg/kg.4 4-Allylcatechol has been used as a precursor in the synthesis of, and is a metabolite of, safrole.5,6
