Isobergapten is a furanocoumarin that has been found in H. persicum and has diverse biological activities.1,2,3 It inhibits α-glucosidase and scavenges DPPH radicals in cell-free assays (IC50s = 0.385 and 28.6 ?M, respectively).1 Isobergapten is active against S. aureus, B. cereus, P. aeruginosa, and S. entritidis (MICs = 125 ?g/ml for all).2 It reduces tumor growth in a B16/F10 murine melanoma model when administered at a dose of 0.5 mg/kg in combination with ultraviolet A (UVA) radiation.3
