A series of new building blocks consisting of 1H-pyrrolo[3,4-b]quinolin-3(2H)-one with potential as selective antitumor agents is described. Compounds were synthesized by using Heck reaction of N-allyl-1H-pyrrolo[3,4-b]quinolin-3(2H)-one with p-bromophenyl acetic acid followed by formation of amide (1a-h, 2a-d) by reaction with several secondary amines in good yields. The cytotoxicity of these compounds was evaluated against human cancer cell lines in vitro (SK-N-NH, A549). Studies suggest that most of these compounds were effective in inhibiting neuroblastoma cell growth, compound 1d was the most potent one (% IC50 = 8.62 mu M).
