ABSTRACT:
The invention is directed to acylhydrazones compounds of Formula I:where R1, R2and A are as defined herein, the use of such compounds as protein tyrosine kinase modulators, particularly inhibitors of c-Met, and the use of such compounds to reduce or inhibit kinase activity of c-Met in a cell or a subject, and modulate c-Met expression in a cell or subject, and the use of such compounds for preventing or treating in a subject a cell proliferative disorder and/or disorders related to c-Met. The present invention is further directed to pharmaceutical compositions comprising the compounds of the present invention and to methods for treating conditions such as cancers and other cell proliferative disorders.
