Study on Anticancer Activity of Extracts of Sponges Collected from Biak Water, Indonesia

Indonesia is center of biodiversity where marine sponges are abundant. a source of bioactive compounds with various pharmaceutical properties such as anticancer, antifungal, antibacterial, antioxidants, anti-inflammatory, and anti-malarial. In a continuation of a search for biologically active molecules from marine organisms we investigated the potency of marine sponges as anticancer. A total of 106 sponge specimens were collected between 3-40 m depths by SCUBA diving in Biak waters during August 2005. The specimens were extracted with methanol to provided crude extracts. The methanolic extracts were tested against NBT-T2 cell line. The assay result showed that 8.5 %, 29.2 % and 46.2 % of the extract have activity against the cell line at 0.1, 1.0 and 10.0 μg/mL. While, a 16.0 % of the extract did not showed activity against the cell line.
