Subditine, a New Monoterpenoid Indole Alkaloid from Bark of Nauclea subdita (Korth.) Steud. Induces Apoptosis in Human Prostate Cancer Cells

In this study, a new apoptotic monoterpenoid indole alkaloid, subditine (1), and four known compounds were isolated from the bark of Nauclea subdita. Complete 1H- and 13C- NMR data of the new compound were reported. The structures of isolated compounds were elucidated with various spectroscopic methods such as 1D- and 2D- NMR, IR, UV and LCMS. All five compounds were screened for cytotoxic activities on LNCaP and PC-3 human prostate cancer...
