Abstract: |
A number of substituted 3-phenylquinazolin-4-ones, 12H-benzoxazolo-[2, 3-b]quinazolin-12-ones and 12H-benzothiazolo[2, 3-b]quinazolin-12-ones were designed and synthesized on the basis of a "2-phenylnaphthalene-type" structural pattern hypothesis. The postulated pattern, which was uncovered among a substantial number of compounds of both natural and synthetic origins, was noted to be associated with compounds possessing a variety of biological properties which include the antineoplastic activity. Several compounds designed for the present study were found to exhibit potent cytotoxicity against the growth of human promyelocytic leukemia (HL-60) cells. © 1993. |
