SALTS AND POLYMORPHIC FORMS OF 6-CHLORO-7-(4-(4-CHLOROBENZYL)PIPERAZIN-1-YL)-2-(1,3-DIMETHYL-1H-PYRAZOL-4-YL)-3H-IMIDAZO4,5-BPYRIDINE

摘要

The present invention relates to salts and polymorphic forms of Compound A (6-chloro-7-(4-(4- chlorobenzyl)piperazin-1-yl)-2-(1,3-dimethyl-1H-pyrazol-4-yl)-3H-imidazo[4,5-b]pyridine), an inhibitor of Aurora kinase and FMS-like tyrosine kinase 3 (FLT3) activity. The present invention also relates to processes for the preparation of the salts and polymorphic forms of the compound, to pharmaceutical compositions comprising them, and to their use in the treatment of proliferative disorders, such as cancer, as well as other diseases or conditions in which Aurora kinase and/or FLT3 activity is implicated.
