NEW APPROACHES FOR THE SYNTHESIS OF CHROMENE AND QUINOLINE DERIVATIVES AND THEIR ANTI-PROLIFERATIVE, MORPHOLOGICAL STUDIES.

This work aimed to evaluate the anticancer potential of the novel 5,6,7,8-tetrahydro-4H-chromenes against selected six cancer cell lines together with the prostate cancer cell line PC-3. A novel series of substituted 5,6,7,8-tetrahydro-4H-chromenes were synthesized through feasible synthetic strategy. The synthetic schemes involve firstly the multi-component reactions of dimedone with the aromatic aldehydes and ethyl acetoacetate to produce the 5,6,7,8-tetrahydro-4H-chromenes derivatives. On the other hand, carrying the same reactions using NH4OAc produced the hexahydroquinoline compounds. Anti-proliferative evaluations and inhibitions for all synthesized compounds toward selected cancer cell lines were carried out and the results revealed that many of them exhibited high inhibitions. Morphology of A549 cell line by the effect of compounds 14f and 16c was performed. [ABSTRACT FROM AUTHOR]
