Enlightened by the modification route from Camptothecin (CPT) to Topotecan and based on classical drug design theory, a series of Mannich derivatives of lamellarin D were designed and synthesized in 26-27 steps starting from vanillin and isovanilin. All synthesized compounds were then biologically evaluated for their in vitro anti-cancer activities and Topo I inhibitory activities. The results showed that most target compounds exhibited Topo I inhibitory activities in equivalent level with that of lamellarin D. Compound SL-9 exhibited better Topo I inhibitory activity than that of lamellarin D. Compounds SL-2, SL-3, SL-4, SL-5 and SL-11 exhibited better anti-proliferative activity against HT-29 cells than that of lamellarin D.

A new series of hybrids of lamellarin D and combretastatin A 4, 1,2-diphenyl-5,6-dihydropyrrolo [2,1-a] isoquinolines, were designed as cytotoxic agents based on principles of combination in medicinal chemistry and taking the parent compounds' different anti-proliferative mechanisms into consideration. Twenty-two novel hybrids were synthesized through a convenient route, with a key step of core pyrrole formation and evaluated for their anti-proliferative activities in vitro against K-562, A-549, SMMC-7721, SGC-7901 and HCT-116 cancer cell lines. The results showed that some hybrids had good anti-proliferative activities in low IC50 ranges.
