Novel pyridazinone compounds of formula (I), which inhibit the purinergic P2X7 receptor and are useful for prevention, therapy and improvement of inflammatory and immunological diseases.
radical cation of each was generated by photochemical oxidation using 1,4-dicyanobenzene as the sensitizer, and their reactivity was examined in methanol-acetonitrile mixtures with added tetraethylammonium cyanide. Although compound 2 reacted only by tautomerization, the other compounds all gave addition products. For the monoaryl alkenes 3, 4, and 5, comparable yields of both methanol and HCN addition

The present invention relates to novel pyrimide derivatives of formula (I): that are useful as kinase inhibitors. More particularly, the present invention relates to novel pyrimidine compounds, methods for their preparation, pharmaceutical compositions containing these compounds and uses of these compounds in the treatment of proliferative disorders.
Deuterium-based i.e. isotopic hydrogen chemiluminescent 1,2-dioxetanes derived from the photo-oxidation of new novel alkenes which are synthesized by the coupling reaction of (a) a saturated or unsaturated cyclic, polycylic, normal or branched chain alkyl, cycloalkyl and spiro-fused and (b) substituted aromatic esters or ketones wherein (a) or (b) or both at least have a deuterium atom or a deuterium atom-containing group. These deuterium-based 1,2-dioxetanes may also have electron donating or withdrawing groups at the four-membered peroxide ring. Thus, the added electronic charge and the isotopic hydrogen or isotopic hydrogen-containing group hereof affects the light producing efficiency of 1,2-dioxetanes.

Alkyl methyl ethers and alkyl methyl carbonates were synthesized by reaction of alcohols with dimethyl carbonate in the presence of tungsten and cobalt carbonyls. Optimal reactant and catalyst ratios, as well as reaction conditions, were found for selective formation of alkyl methyl ethers or alkyl methyl carbonates.
