Identification of novel PPARα ligands by the structural modification of a PPARγ ligand
摘要:
To develop novel PPAR alpha ligands, we designed and synthesized several 3-{3-[2-(nonylpyridin-2-ylamino)ethoxy]phenyl}-propanoic acid derivatives. Compound 10, the meta isomer of a PPAR gamma agonist 1, has been identified as a PPAR alpha ligand. The introduction of methyl and ethyl groups at the C-2 position of the propanoic acid of 10 further improved the PPAR alpha-binding potency. (c) 2006 Elsevier Ltd. All rights reserved.
A general and efficient protocol for the Michaeladdition reactions of β-ketoesters in pure water has been developed. The reactions are successfully catalyzed by newly designed DMAP-related organocatalysts such as 4-(didecylamino)pyridine, and the desired Michael adducts are obtained in good to high yields

Reduction of alkyl, aryl and aroyl azides to the parent primary amines or amides, respectively, occurs in good yield upon treatment with an excess of SmI2 in THF at room temperature. A radical mechanism is proposed.
To develop novel PPAR gamma ligands, we synthesized thirteen 3-4-(2-aminoethoxy)phenyl}propanoic acid derivatives, which are designed based on the structures of rosiglitazone and 15d-PGJ(2). Among these compounds, compound 9 was found to be as potent as rosiglitazone in a binding assay and a preadipocyte differentiation test. Molecular modeling suggested that the nonyl group of 9 interacted with hydrophobic amino acid residues constructing the hydrophobic region of PPAR gamma protein where the alkyl chain of 15d-PGJ(2) is expected to be located.
