Abstract :

As part of our ongoing efforts to identify biologically active compounds from marine invertebrates, the organic extract of the Red Sea sponge Hemimycale arabica was investigated. Bioassay-directed fractionation of the organic extract of the sponge gave two new hydantoin alkaloids, hemimycalin C and (E)-5-(4-hydroxybenzylidene)imidazolidine-2,4-dione in addition to the known compounds hemimycalins A and B and (Z)-5-(4-hydroxybenzylidene)imidazolidine-2,4-dione. The structure determinations of the isolated compounds were based on interpretation of the spectral data of the compounds including one- (1H and 13C) and two-dimensional NMR (COSY, HSQC and HMBC) studies as well as HRMS. The new compounds hemimycalin C and (E)-5-(4-hydroxybenzylidene)imidazolidine-2,4-dione displayed variable antimicrobial activities against E. coli, S. aureus and C. albicans. Finally, hemimycalin C showed moderate antiproliferative activity against the human cervical carcinoma (HeLa) cell line.
