A triterpenoid with diverse biological activities
Lupenone is a triterpenoid that has been found in L. eriocalyx and has diverse biological activities.1,2,3,4 It inhibits HIV-1 reverse transcriptase (IC50 = 2.1 μM).1 Lupenone is active against the W2 and D6 strains of P. falciparum (IC50s = 208.1 and 394.7 ng/ml, respectively).2 It induces melanogenesis in (EC50 = 0.35 ?M), and inhibits the growth of, B16 2F2 melanoma cells in vitro (IC50 = 25.4 ?M).3 Topical application of lupenone (1 mg/ear) reduces ear edema induced by phorbol 12-myristate 13-acetate in mice.4 It also inhibits acetic acid-induced writhing in mice when administered at a dose of 100 mg/kg.2
