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.
A rhodium(III)-catalyzed Satoh–Miura type oxidative annulation of N-aryl 2-pyridone derivatives is described using internal alkyne as a coupling partner. A weakly coordinating carbonyl group of the 2-pyridone ring is utilized for this transformation. The reaction proceeds with a broad scope and wide functional group tolerance. The solvent plays an important role in the developed method to furnish a

A weakly coordinating biorelevant intrinsic directing group (DG) assisted site-selective C–H alkenylation viasequential C–H/C–C bond activation has been accomplished under Ru(II)-catalysis using readily accessible cyclopropyl alcohol as an alkenyl surrogate. Utilization of an intrinsic DG, exclusive regioselectivity, functional group diversity, late-stage natural product and drug mutations are the

Palladium-catalyzed weak chelation-assisted oxidative cross-dehydrogenativecoupling of arenes has been accomplished. The use of medicinally important pyridones as the intrinsic directing group, regioselectivity, 2-fold C–H activation, and late-stage modification of bioactive compounds are the important practical features.
