Abstract: Compounds and methods useful for treating and prevention of cancer, particularly hormone-dependent breast cancer. Provided are compounds of formula I: wherein X is selected from O, N, S, SO, SO2, and S(CH2)n, wherein n=1-10; R1 and R2 may be the same or different and are selected from H, OH, OCH3, OCH2CH3, OCH2C6H5, NH2, NHCH3, N(CH3)2, CH3, CH2CH3, CH2CH2CH3, CH(CH3)2, C(CH3)3, NO2, F, Cl, Br, CF3, SH, SCH3, SCH2CH3, OCOCH3, OCOC(CH3)3, OCOCH2COOH, and CN; and R3 is a nitrogen-containing heterocyclic ring. Also provided are method for treating or preventing cancer in a subject by administering a therapeutically effective amount of a heteroaryl-containing isoflavone, or a pharmaceutically acceptable salt or prodrug thereof, to a subject in need of treatment.

Abstract: Compounds and methods for treating, inhibiting, or delaying the onset of cancer in a subject by administering a therapeutically effective amount of a keratinocyte growth factor receptor tyrosine kinase (KGFR TK) inhibitor to the subject in need of such treatment. Also provided are compounds and methods for the treating, inhibiting, or delaying the onset of metastasis in a subject with cancer by administering a therapeutically effective amount of a KGFR TK inhibitor to the subject in need of such treatment.
