Novel compounds and methods of using those compounds for the treatment of inflammatory conditions are provided. In a preferred embodiment, modulation of the activation state of p38 kinase protein comprises the step of contacting the kinase protein with the novel compounds.
Abnormal Diels-Alder Reaction of 5-Alkoxythiazoles with Highly Reactive Dienophiles; 4-Phenyl-3<i>H</i>-1,2,4-triazole-3,5(4<i>H</i>)-dione, Diethyl Azodicarboxylate, and Diethyl Oxomalonate
thiazole ring opening. Diethylazodicarboxylate also gave 2,3-dihydro-1H-1,2,4-triazole derivatives in moderate yields. High pressure improved the yields a little. On the other hand, the reaction of diethyl oxomalonate in the presence of tin tetrachloride with 4-unsubstituted thiazoles did not give an adduct of similar type but gave diethyl 2-hydroxy-2-(4-thiazolyl)malonate through the usual electrophilic
