Trisubstituted pyridazines were synthesized and evaluated as in vitro inhibitors of p38 MAPK. The most active isomers were those possessing an aryl group alpha and a heteroaryl group beta relative to the nitrogen atom in the 2-position of the central pyridazine. Additionally, substitution in the 6-position of the central pyridazine with a variety of dialkylamino substituents afforded a set of inhibitors having good (p38 IC50 1-20 nM) in vitro activity.

Compound (II) is reacted with formate in the presence of an alkali metal alkoxide and the like to give compound (III); then this is reacted with compound (IVa) or compound (IVb) to give compound (V); then this is reacted with compound (VI) to give compound (VII); and then this is deprotected to give compound (I).
The present invention provides an industrially advantageous production method of a 4-acetylpyrimidine compound useful as a synthetic intermediate for a pharmaceutical product:
wherein X is a methylthio group and the like, R1 is a lower alkyl group and the like, R2 is a lower alkyl group optionally having substituent(s) and the like, M is an alkali metal and X1 is a halogen atom.
There are disclosed compounds of formula (I)
and pharmaceutically acceptable salts thereof which exhibit utility for the treatment of cytokine mediated diseases such as arthritis.

The present invention relates to 6,7-dihydro-5H-pyrazolo[1,2a]pyrazol-1-ones which inhibit the extracellular release of inflammatory cytokines, said cytokines responsible for one or more human or higher mammalian disease states. The present invention further relates to compositions comprising said 6,7-dihydro-5H-pyrazolo[1,2a]pyrazol-1-ones and methods for preventing, abating, or otherwise controlling enzymes which are understood to be the active components responsible for the herein described disease states.
The present invention relates to compounds which inhibit, regulate and/or modulate tyrosine kinase signal transduction, compositions which contain these compounds, and methods of using them to treat tyrosine kinase-dependent diseases and conditions, such as angiogenesis, cancer, tumor growth, atherosclerosis, age related macular degeneration, diabetic retinopathy, inflammatory diseases, and the like in mammals.
Described herein are compounds, pharmaceutical compositions and methods for the inhibition of RAF kinase mediated signaling. Said compounds, pharmaceutical compositions and methods have utility in the treatment of human disease and disorders.
