Synthesis and evaluation of novel marine bromopyrrole alkaloid-based hybrids as anticancer agents.

A series of twenty three novel hybrids of marine bromopyrrole alkaloids with chalcone, isoxazole and flavone structural features were synthesized and evaluated for in vitro anticancer activity by MTT assay against five human cancer cell lines. Among the synthesized chalcones, hybrids 4a and 4h (IC50 range: 0.18 μM-12.

Synthesis and evaluation of novel 1,3,4-oxadiazole derivatives of marine bromopyrrole alkaloids as antimicrobial agent.

In an attempt to identify new potential lead as antimicrobial agent, twenty hybrids of marine bromopyrrole alkaloids with 1,3,4-oxadiazole were designed based on molecular hybridization technique and synthesized. Synthesized molecules were evaluated for their antibacterial, antifungal and antitubercular activities. Hybrids 5d, 5i, 5j and 5k exhibited equivalent antibacterial activity (MIC of 1.
