The present invention features compounds and methods for inhibiting hyper-proliferative cell growth. The compounds and method are preferably used to treat patients having a hyper-proliferative cell disorder. The compounds are preferably of formulas (I.A) and (I.B) wherein T is carbon or nitrogen; if T is carbon m is either 0, 1, 2, 3, 4 or 5; and if T is nitrogen m is either 0, 1, 2, 3 or 4; each X is independently selected from the group consisting of: SH, OH, lower alkyl, lower alkenyl, lower alkoxy, haloalkoxy, halogen, haloalkyl, cyano, sulfonyl-aryl, amino, aminosulfonyl, and NO2; R1 is hydrogen or lower alkyl; R3 is selected from the group consisting of: hydrogen, carboxy, alkoxy, and carbalkoxy; R4 is selected from the group consisting of: alkyl, alkenyl, alkyl-aryl, alkenyl-aryl, and alkynyl-aryl; R5 is hydrogen or a group which is cleavable in vivo; and pharmaceutically acceptable salts thereof. |
