Epolactaene, isolated from cultured Penicillium sp. BM 1689-P mycelium, induces neurite outgrowth and arrests the cell cycle of the human neuroblastoma cell line, SH-SY5Y, at the G1 phase. We have found that epolactaene and its derivatives induce apoptosis in the human leukemia B-cell line, BALL-1. In this study, we prepared fluorescent and biotinylated epolactaene derivatives. We characterized the cellular location and the identification of BALL-1 proteins that reacted with these compounds. The results obtained from the reaction of epolactaene or its derivative with N-acetylcysteine methyl ester indicate that these compounds induce the disulfide formation and the alpha-position of the epoxylactam core is the reactive site.
