enzyme, which is a target for inhibition of the conversion of glycogen to glucose-1-phosphate. In this study we report the design and synthesis of 14 new pyridonederivatives, and seek to extend the SAR analysis of these compounds. The SAR revealed the minor influence of the amide group, importance of the pyridone ring both spatially around the pyridine ring and for possible π-stacking, and confirmed

The present application relates to novel Pyrimidine-2,4-diamine derivatives as kinase inhibitors derivatives of formula (I), as protein kinase inhibitors. Formula (I). The invention particularly relates to compounds of formula (I), preparation of compounds and pharmaceutical compositions thereof. The invention further relates to prodrugs, derivatives, polymorphs, pharmaceutically acceptable salts and compositions comprising the said novel Pyrimidine-2,4-diamine derivatives as kinase inhibitors and their derivatives and their use in the treatment of various disorders.
Herein, we report a novel regioselective [2 + 1] cyclization reaction of 2-pyridones with carbenes generated in situ via visible light irradiation, without the requirement for catalysts or additives. The diverse functional groups of 2-pyridones and diazo compounds exhibit good tolerance, enabling the rapidsynthesis of highly valuable cyclopropanated dihydro-2-pyridone scaffolds with exceptional regio-

A series of 3-urea-1-(phenylmethyl)-pyridones was discovered as novel EP3 antagonists via high-throughput screening and subsequent optimization. The synthesis, structure-activity relationships, and optimization of the initial hit that resulted in potent and selective EP3 receptor antagonists such as 11g are described. (C) 2010 Elsevier Ltd.

Alkylation of 3-nitropyridin-2(1H)-ones in the presence of bases affords N-alkylated products and sometimes O-alkylated products. The yields and relative amounts of N- and O-alkylated products depend substantially on the size of the substituent at the C(6) atom of pyridone.
