RESUMEN
The development of a series of novel 4-substituted-2-aminopyrimidines as inhibitors of c-Jun N-terminal kinases is described. The synthesis, in vitro inhibitory values for JNK1, and the in vitro inhibitory value for a c-Jun cellular assay are discussed. Optimization of microsomal clearance led to the identification of 9c, whose kinase selectivity is reported.

A series of pyridine ether PPAR agonists were synthesized through an ADDP and PS-PPh3 modified Mitsunobu protocol, which eliminated significant by-product formation. This method proved to be versatile, efficient and amenable to parallel synthesis.
RESUMEN
A series of novel pyridine-2-propanoic acids was synthesized. A structure-activity relationship study of these compounds led to the identification of potent dual PPARalpha/gamma agonists with varied isoform selectivity. Based on the results of efficacy studies in diabetic (db/db) mice, and the desired pharmacokinetic parameters, compound (S)-13 was selected for further profiling.
