excellent antitumor activity versus all cancer cell lines with IC50 values ranging from 0.2 to 1.7 μM. The cellcyclearrest behavior of compounds 4e, 4f, and 4m was investigated. The results illustrated that the potent cytotoxic compounds 4e, 4f, and 4m induce cellcyclearrest at the G2/M phases and trigger apoptosis in the different tested cancer cells. Finally, the structure activity relationship

AbstractA series of fifteen 2‐amino‐4‐aryl‐5‐oxo‐4,5‐dihydropyrano[3,2‐c]chromene‐3‐carbonitriles (1 a–o) were synthesized via a three‐component reaction of 4‐hydroxycoumarin, malononitrile, and diversely substituted benzaldehydes or pyridine carbaldehydes. The compounds were tested for anticancer activities against a panel of eight human tumor cell lines. A few derivatives with high antiproliferative activities and different cancer cell specificity were identified and investigated for their modes of action. They led to microtubule disruption, centrosome de‐clustering and G2/M cell cycle arrest in 518 A2 melanoma cells. They also showed anti‐angiogenic effects in vitro and in vivo.
