Disclosed are compounds and methods for treating inflammatory and fibrotic disorders, including methods of modulating a stress activated protein kinase (SAPK) system with an active compound, wherein the active compound exhibits low potency for inhibition of the p38 MAPK; and wherein the contacting is conducted at a SAPK-modulating concentration that is at a low percentage inhibitory concentration for inhibition of the p38 MAPK by the compound. Also disclosed are derivatives and analogs of pirfenidone, useful for modulating a stress activated protein kinase (SAPK) system.

DOI:10.1039/c5ra26360c
日期:——
efficient production of functionalized furo[3,2-c]-pyridones-2 when terminal alkenes are utilized and 3-alkenyl-4-hydroxy-2-pyridones when more substituted reaction partners are involved. The mild reaction conditions allow easy, scalable access to pyridone derivatives that resemble core structures isolated from natural alkaloids.
在常规的乙酸钯催化下,已经实现了N-取代的-4-羟基-2-吡啶酮与未活化的烯烃的首次直接C-3烯基化。当使用末端烯烃时,提出的方案能够有效地生产官能化的呋喃并[3,2 - c ]-吡啶酮-2,而在涉及更多取代的反应伙伴时,则可以生产3-烯基-4-羟基-2-吡啶酮。温和的反应条件允许轻松,可扩展地获得类似于从天然生物碱中分离出的核心结构的吡啶酮衍生物。
Synthesis of Multifunctionalized 2,3-Dihydro-4-pyridones and 4-Pyridones via the Reaction of Carbamoylated Enaminones with Aldehydes

The novel and effective diastereoselective synthesis of multifunctionalized dihydropyridones, including CF3-substituted derivatives, has been developed on the basis of the piperidine-promoted domino reaction of carbamoylated enaminones with aldehydes. The products have been prepared in 38–90% yields and can be easily isolated by crystallization. Tautomerism, epimerization, and atropisomerism of dihydropyridones
