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.

Phospholipase A
2
(PLA
2
) forms are expressed in spinal cord whose inhibition induces a potent antihyperalgesia. PLA
2
inhibitor compounds are provided that include a common motif consisting of a 2-oxoamide with a hydrocarbon tail and a four carbon tether. The compounds block Group IVA calcium dependent PLA
2
(cPLA
2
) and/or Group VIA calcium independent PLA
2
(iPLA
2
) and/or Group V secreted PLA
2
(sPLA
2
). Pharmaceutical compositions of compounds having cPLA
2
inhibitory activity (but not iPLA
2
or sPLA
2
inhibitory activity) are useful in treating multiple sclerosis, while compositions of compounds having sPLA
2
inhibitory activity (as well as iPLA
2
and CPLA
2
activity) are useful in treating spinal cord injuries (with related functional recovery).
