hyperactivation of AKT and reactive oxygen species-mediated apoptosis. Herein, we report the identification of the novel potent and highly selectiveinhibitors BAY-091 and BAY-297 of the kinase PIP4K2A by high-throughput screening and subsequent structure-based optimization. Cellular target engagement of BAY-091 and BAY-297 was demonstrated using cellular thermal shift assay technology. However, inhibition of PIP4K2A
Provided are pyrazine compounds for inhibiting of Syk kinase, intermediates used in making such compounds, methods for their preparation, pharmaceutical compositions thereof, methods for inhibition Syk kinase activity, and methods for treating conditions mediated at least in part by Syk kinase activity.
(R)-alpha-ethyl-2-oxo-1-pyrrolidineacetamide, its preparation and pharmaceutical compositions containing the same. It can be prepared either by reacting (R)-alpha-ethyl-2-oxo-1-pyrrolidineacetic acid successively with an alkyl haloformate and with ammonia, or, by cyclizing an (R)-2-amino-butanamide of the formula X--CH.sub.2 CH.sub.2 --Y--NHCH(C.sub.2 H.sub.5)CONH.sub.2 wherein Y is a --CH.sub.2 -- radical when X represents a ZOOC-- radical and Y is a --CO-- radical when X represents a HalCH.sub.2 -- radical, Z being a C.sub.1 -C.sub.4 alkyl radical and Hal a halogen atom. This dextrorotatory enantiomer has been found to have significantly higher mnemic activity and lower toxicity than the corresponding racemate.
