Synthesis and biological evaluation of [4-(2-phenylethenesulfonylmethyl)phenyl]-quinazolin-4-yl-amines as orally active anti-cancer agents.

ABSTRACT

A new series of [4-(2-phenylethenesulfonylmethyl)phenyl]quinazolin-4-yl-amines was prepared and tested for its in vitro cytotoxic activity against a panel of 12 human cancer cell lines. Compounds 9, 15, 24 and 31 showed good in vitro activity and were further tested for their in vivo efficacy in the HT-29 human colon adeno carcinoma xenograft model. Compound 9 exhibited promising activity in this model. Dose-response studies for this compound against HT-29 human colon adeno carcinoma xenografts at 100, 200 and 400mg/kg doses were performed.
