COMPOSITIONS FOR MODULATING A KINASE CASCADE AND METHODS OF USE THEREOF
The invention relates to compositions comprising 2-(5-(4-(2-morpholinoethoxy)phenyl) pyridin-2-yl)-N-benzylacetamide and its mesylate and dihydrochloride salts. The invention provides an efficient process for the synthesis of 2-(5-(4-(2-morpholinoethoxy)phenyl)pyridin-2-yl)-N-benzylacetamide and its mesylate and dihydrochloride salts and methods for modulating one or more components of a kinase cascade using the compositions of the invention. The present invention also provides a novel polymorph of the mesylate salt of 2-(5-(4-(2-morpholinoethoxy)phenyl)pyridin-2-yl)-N-benzylacetamide (Form A), characterized by a unique X-ray diffraction pattern and Differential Scanning calorimetry profile, as well as a unique crystalline structure.
1 . A composition comprising 2-(5-(4-(2-morpholinoethoxy)phenyl) pyridin-2-yl)-N-benzylacetamide, or a pharmaceutically acceptable salt or solvate thereof.
2 . A polymorph of 2-(5-(4-(2-morpholinoethoxy)phenyl) pyridin-2-yl)-N-benzylacetamide, or a pharmaceutically acceptable salt or solvate thereof.
3 . A method of treating or preventing a disease or disorder modulated by a kinase, comprising administering to a subject in need thereof, a pharmaceutically effective amount of the composition of claim 1 .
4 . A method of treating or preventing a disease or disorder modulated by a kinase, comprising administering to a subject in need thereof, a pharmaceutically effective amount of the polymorph of claim 2 .
5 . A method of preparing a polymorph of 2-(5-(4-(2-morpholinoethoxy)phenyl) pyridin-2-yl)-N-benzylacetamide, or a pharmaceutically acceptable salt or solvate thereof.
