Marine sources have long been known for their potential to produce unique skeletons and various biological activities. Fractionation of the ethanol extracts of an undescribed species of MonanchoraCarter, 1883 and a specimen closely comparable to Monanchora pulchra (Lambe, 1894/1895) (Class Demospongiae, Order Poecilosclerida, Family Crambeidae), yielded a known compound, monanchocidin A. Monanchocidin A, a secondary metabolite, showed very modest antibacterial, antifungal, and antiprotozoal activities with IC50 values ranging between 255.75 and 7288.92 μM. Monanchocidin A also exhibited potent selective activity for the melanoma panel in the NCI cancer cell screening panel.
