Research uncovers anticancer properties of a new stilbene in Macaranga aenigmatica, suggesting potential cancer treatment options.
An undescribed stilbene, macaenigmaticin A (1), together with two known compounds, mappain (2) and macapruinosin A (3), were isolated from Macaranga aenigmatica Whitmore leaves. The structure of 1 was determined from a combination of ESI-HRMS and NMR spectra. Cytotoxicity was tested against the HeLa (cervical cancer) and P-388 (murine leukaemia) cell lines. Macaenigmaticin A (1) and macapruinosin A (3) were potent against P-388 cells, with IC₅₀ values of 1.15 and 1.53 µg/mL, respectively. Stibenes 1-3 were inactive against HeLa cells.
