Structure–activity relationships of natural and non-natural amino acid-based amide and 2-oxoamide inhibitors of human phospholipase A2 enzymes
摘要:
A variety of 2-oxoamides and related amides based on natural and non-natural amino acids were synthesized. Their activity on two human intracellular phospholipases (GIVA cPLA(2) and GVIA iPLA(2)) and one human secretory phospholipase (GV sPLA(2)) was evaluated. We show that an amide based on (R)-gamma-norleucine is a highly selective inhibitor of GV sPLA2. (C) 2008 Elsevier Ltd. All rights reserved.

A novel approach to 2-substituted-2-(dimethoxyphosphoryl)-pyrrolidines 7a–7o and 9a–9r has been developed, which features a TMSOTf-mediated one-pot intramolecular cyclization and phosphonylation of substituted tert-butyl 4-oxobutylcarbamates. The major advantages of this method include simple operation under mild reaction conditions, the use of cheap Lewis acid, and good to excellent yields with high
Functionalized Polyhydroquinolines from Amino Acids Using a Key One-Pot Cyclization Cascade and Application to the Synthesis of (±)-Δ<sup>7</sup>-Mesembrenone
developed a one-pot cyclization cascade with high chemocontrol and diastereoselectivity. The sequence generates two cycles, three carbon–carbon bonds, and an all-carbon quaternary center in a highly convergent process. Functionalized polyhydroquinolines and congeners can be accessed from commercially available amino acids. This versatile and robust strategy was applied to the synthesis of (±)-Δ7-mesembrenone
