title: Prenylated 2-arylbenzofurans from Artocarpus petelotii.
abstract: Further phytochemical investigation on the root barks of Artocarpus petelotii Gagnep afforded two new prenylated 2-arylbenzofurans, artopetelins L and M (1 and 2), as well as a known compound, lakoochin B (3). Their structures were identified by spectroscopic methods. Artopetelins B-E (5-8), four 2-arylbenzofurans previously isolated from this plant, and lakoochin B (3) were potent against HepG2 (IC(50) = 14.4-44.4 microM) and MCF-7 (IC(50) = 29.7-59.1 microM).
