analyses. The antiproliferative properties of some of the products against human cancer cell lines were comparable to those of cisplatin. Structureactivity analysis showed that the presence of hydrophobic substituents in both heterocyclic fused and phenyl rings of the compounds improves their biological effects. Further, an additional OH group in the resorcinol moiety reduced the antiproliferative activity
