De novo design, synthesis and biological evaluation of 1,4-dihydroquinolin- 4-ones and 1,2,3,4-tetrahydroquinazolin-4-ones as potent kinesin spindle protein (KSP) inhibitors

Kinesin spindle protein (KSP) inhibitors are a promising class of anticancer agents that cause mitotic arrest in cells from a failure to form functional bipolar mitotic spindles. Here, we report the design, synthesis and biological evaluation of a novel series of 1,4-dihydroquinolin-4-ones and 1,2,3,4-tetrahydroquinazolin-4-ones using de novo design method. The synthesized compound was evaluated and proved to have potent inhibitory activities in the KSP ATPase. Compounds 15j and 15p show potent inhibitory activities in cell proliferation assays. Preferred compound 15j markedly induced G2/M phase cell cycle arrest with characteristic monoastral spindles and subsequent cell death in A549 cells. In vivo evaluation of 15j on the growth of transplantable S180 sarcoma in mice suggested its therapeutic potential for further development.

PYRIDINE COMPOUNDS

The present invention relates to compounds that inhibit of focal adhesion kinase function, processes for their preparation, pharmaceutical compositions containing them as the active ingredient, to their use as medicaments and to their use in the manufacture of medicaments for use in the treatment in warm-blooded animals such as humans of diseases such as cancer.

INHIBITORS OF FOCAL ADHESION KINASE

The invention provides inhibitors of focal adhesion kinase, an enzyme involved in the attachment of the cytoskeleton of a cell to an extracellular matrix, which has been implicated in processes such as cell migration, cell proliferation, and cell survival. The inhibitors are derivatives of a 5-substituted 2,4-diaminopyridine wherein the substituents are as defined herein. The invention also provides a method of using the inhibitors in treatment of cancer, and methods of preparation of the inhibitors by use of coupling reactions.
