Abstract

Cancer is still a major problem and common cause of death around the world. Various therapeutic agents have been developed to fight against cancer, but none of these agents give satisfactory results and without debilitating side effects. A number of researches have been conducted to search anticancer compounds with renewed vigour.Sponges, marine invertebrates, are known as rich sources of compounds which pronounced pharmacological activities. The aims of this study are to determine cytotoxic effect of two toxic compounds isolated from chloroform fraction of Petrosia sp sponges collected from Bunaken on myeloma cells.The two toxic compounds were isolated based on bioassay guidedisolation on brine shrimp larvae. Isolation was conducted using column chromatography followed by preparative TLC. Cytotoxic effect of the two compounds was conducted in 96 well plate using RPMI 1640 as medium. The number of viable cells was determined using MTT assay and LC50 (μg/mL) of the compounds was analysed using probit analysis.The results showed that the two compounds were alkaloid and toxic to larva A. salina with LC50 of 7.23 (compound 1) and 5.69 μg/mL (compound 2). These compounds were also toxic to myeloma cells with LC50 values of 16.95 μg/mL (compound 1) and 18.8 μg/mL (compound 2). The longer the incubation time, the compounds were more toxic as showed by the lower LC50 values .Key words: cytotoxic, Petrosia sp, Artemia salina Leach, myeloma

Abstract

Two alkaloid compounds have been isolated from sponge Petrosia sp collected from Bunaken Bay Menado. These compounds have been found to inhibit several human cancer cell proliferation in vitro. Structure elucidation is needed to further characterize these bioactive compounds. The structure is determined by analyzing Ultra Violet (UV), Infra Red (IR), Mass Spectra (MS) and Nuclear Magnetic Resonance (NMR) spectra. Based on spectroscopic data, Thin Layer Chromatography (TLC) co-chromatograph with authentic samples and comparison with reported data the two compounds were identified as Manzamine A and 8-OH Manzamine A, respectively. Keywords: Manzamine A, 8-OH Manzamine A, Petrosia sp, stucture elucidation
