  • Title: New jasmonate analogues as potential anti-inflammatory agents.
    Author: Dang HT, Lee HJ, Yoo ES, Hong J, Bao B, Choi JS, Jung JH.
    Journal: Bioorg Med Chem; 2008 Dec 15; 16(24):10228-35. PubMed ID: 18996699.
    Abstract:
    In an effort to develop new anti-inflammatory agents, methyl jasmonate analogues (2-20) were synthesized and evaluated for their inhibitory effects on the production of pro-inflammatory mediators (NO, IL-6, and TNF-alpha) in lipopolysaccharide (LPS)-activated RAW264.7 murine macrophage cells. The introduction of an enone functionality to the structure of a plant hormone (1) rendered the product (2) a significant anti-inflammatory activity. Analogues further derived from 2 (7, 9, 13, and 15) exhibited even more enhanced activity, and these compounds were much more potent than natural anti-inflammatory prostaglandins (PGA(1), PGA(2), and 15-deoxy-Delta(12,14)-PGJ(2)). Among them, compounds 9 and 15 showed the highest potency, while compounds 7 and 13 would be more desirable with respect to safety. This is the first study demonstrating the anti-inflammatory potential of jasmonate derivatives, and the present results suggest that alpha-haloenone jasmonates (7, 9, 13, and 15) may serve as potential anti-inflammatory leads.
