Compounds and pharmaceutical compositions that modulate kinase activity, including PI3 kinase activity, and compounds, pharmaceutical compositions, and methods of treatment of diseases and conditions associated with kinase activity, including PI3 kinase activity, are described herein.
A series of hydroxamicacid derivatives bearing a cyclic amide/imide group as a linker and/or cap structure, prepared during our structural development studies based on thalidomide, showed class-selective potent histonedeacetylase (HDAC)-inhibitory activity. Structure-activity relationship studies indicated that the steric character of the substituent introduced at the cyclic amide/imide nitrogen

A transition metal compound represented by the formula (1-1) or the formula (1-2) (M is a transition metal atom) and a process for producing a catalyst for olefin polymerization comprising a step of bringing the transition metal compound into contact with a co-catalytic component for activation.
Pharmaceutical compositions of the invention include substituted riluzole prodrugs useful for the treatment of cancers including melanoma, breast cancer, brain cancer, and prostate cancer through the release of riluzole. Prodrugs of riluzole have enhanced stability to hepatic metabolism and are delivered into systemic circulation by oral administration, and then cleaved to release riluzole in the plasma via either an enzymatic or general biophysical release process.
