Abstract: Disclosed herein are, inter alia, inhibitors of protein arginine methyltransferase 9 and pharmaceutical compositions thereof, and methods comprising the use of protein arginine methyltransferase 9 inhibitors for the treatment of a protein arginine methyltransferase 9-modulated disease or disorder, such as a hematological cancer.

Abstract: Molecules that selectively inhibit or stimulate the activity of isoforms of calpains are presented. Methods for screening and characterizing such molecules are also presented. Specific functions of calpain-1 calpain-2 in long term potentiation (LTP), learning and memory, neurodegeneration and diseases of synaptic dysfunction are characterized using novel calpain inhibitors, substrates and related methods. The compounds, compositions, and methods described herein are expected to be useful, for treating neurodegenerative diseases and other diseases of synaptic function, and for modulating cognition in patients in need thereof.
