Objective: This study was taken to examine the cytotoxicity of the bioactive fraction isolated from marine sponge Calthropella sp. as a preliminary anticancer assay and identify its bioactive compounds.

Methods: The cytotoxic activity was assessed by 3-(4,5-dimethylthiazol-2-y1)-2,5-diphenyltetrazolium bromide assay against three human cancer cell lines, namely human breast (MCF-7), human lung (H-460), and human liver (HepG-2). The bioactive compounds were identified using a high-resolution liquid chromatography–mass spectroscopy (LC–MS).

Results: The active fraction 7 showed moderate to strong cytotoxic activity on all cell lines tested and promising a strong potent cytotoxicity against MCF-7 cell lines with IC50 value as low as 1.925 μg/mL comparable to control, cisplatin (IC50 0.977 μg/mL). In regard to the promising bioactive compounds, the high-resolution LC–MS predicted the existing of several known compounds such as bengamide Q, clavepictine A, 4’-N-methyl-5’- hydroxystaurosporine, carteriofenone A, and one strong possibility of a new compound.

Conclusion: This study has revealed that the isolated bioactive fraction of Indonesian tidal sponge, Calthropella sp., possesses potential anticancer properties with a promising significant cytotoxicity on MCF-7 cell lines (IC50 1.925 μg/mL).

Keywords: Calthropella sp., 3-(4, 5-Dimethylthiazol-2-y1)-2, 5-diphenyltetrazolium bromide assay, MCF-7, H-460, HepG-2.
