摘要:
This invention is in the field of antiinflammatory pharmaceutical agents and specifically relates to compounds, compositions and methods for treating disorders mediated by cyclooxygenase-2 or 5-lipoxygenase, such as inflammation. Compounds of particular interest are defined by Formula I wherein A, Y, R1, R2, R3, R4 and R5 are as defined in the specification.
摘要:
The present invention provides compounds of formula I and processes for the preparation and purification thereof. Compounds of formula I are useful as intermediates in the manufacture of 6-(arylcarbonyl)-4-oximino-dihydrobenzothiopyran herbicidal agents.
摘要:
aP2 inhibiting compounds are provided having the formula wherein R1, R2, R3, R4, X-Z and are as described herein. A method is also provided for treating diabetes and related diseases, especially Type II diabetes, employing such aP2 inhibitor or a combination of such aP2 inhibitor and another antidiabetic agent such as metformin, glyburide, troglitazone and/or insulin.
摘要:
Pyrazole derivatives are prepared by reacting carbonyl compounds R1—C(O)—CH(R2)—CH2R3 with hydrazine, its hydrate or its salts in 30 to 100% by weight sulfuric acid in the presence of catalytic amounts of iodine or of an iodine compound.
摘要:
1-Alkyl-pyrazole-5-carboxylic esters are obtained with surprisingly low proportions of 1-alkyl-pyrazole-3-carboxylic esters if a 2,4-diketo ester and/or an enolate thereof is reacted with an alkylhydrazine and/or a corresponding alkylhydrazinium salt, if appropriate, in the presence of a solvent and/or of water, in such a manner that during at least about 90% of the reaction free alkylhydrazine is present.
摘要:
A “one-pot” process is described herein for the production of pyrazole compounds of general formula (II) comprising the steps of reacting a compound of general formula (III) with an acylating agent in the presence of a base and an optional activating agent followed by the addition of a hydrazine compound in situ.
