TARTRATE SALTS OR COMPLEXES OF QUINAZOLINE BASED EGFR INHIBITORS CONTAINING A ZINC BINDING MOIETY

摘要

The present invention relates to tartrate salts of quinazoline containing zinc-binding moiety based derivatives of Formula II, below. These compounds are inhibitors of epidermal growth factor receptor tyrosine kinase (EGFR-TK) and may further act as HDAC inhibitors. The invention further relates to the use of these tartrate salts in the treatment of EGFR-TK related diseases and disorders such as cancer.
