Discovery of substituted 6-pheny-3H-pyridazin-3-one derivatives as novel c-Met kinase inhibitors
摘要:
We report a series of phenyl substituted pyridazin-3-ones substituted with morpholino-pyrimidines. The SAR of the phenyl was explored and their c-Met kinase and cell-based inhibitory activity toward c-Met driven cell lines were evaluated. Described herein is a potent c-Met inhibitor by structural modification of the parent morpholino-pyridazinone scaffold, with particular focus on the phenyl and pyrimidine substituents.

the compounds with a phenyl ring in the 6-position of the pyridazine ring exhibited appreciable anticonvulsant activity. Furthermore, a 4-hydroxypiperidine side chain in the 3-position of the pyridazine ring appeared essential for anticonvulsant activity. Substituting the phenyl ring with a Cl in the 2-position led to a substantial increase of activity; disubstituting the phenyl ring with a Cl in the
The present invention relates to both a novel method of preparing hydralazine hydrochloride and to a novel method of preparing hydrazine derivatives of compounds containing a pyridazine ring, including, for example, pyridazines, phthalazines and other compounds containing the pyridazine ring.
The present invention relates to stable and highly purified stable hydralazine hydrochloride compositions and stable hydralazine-containing pharmaceutical compositions. A sterile aqueous injectable pharmaceutical composition suitable for parenteral administration is described comprising a therapeutically effective dose of hydralazine hydrochloride in a pharmaceutically acceptable carrier or diluent wherein said hydralazine hydrochloride is essentially free of phthalazines, hydrazine and metal ions. In addition, a stable sterile aqueous pharmaceutical composition comprising hydralazine hydrochloride in a pharmaceutically acceptable salt or diluent is described that is colorless and has no visible particulate matter.
