Physicochemical Information
[ α ]D +45.5°(C 0.22, CHCl3) KikuchiHet al.
Clavulones are soluble in MeOH, EtOH, CHCl3, or hexane.
Clavulones were isolated from Japanese soft coral, Stolonifer Clavularia viridis Quoy and Gaimard. Kikuchi_H et al. Kobayashi_M et al. Kikuchi_H et al. Kobayashi_M et al.
Clavulones were synthesized from L-(+)-diethyl tartarate and D-mannitol as a natural form. Nagaoka_H et al.Other synthesis of clavulone. Hashimoto_S et al. Klunder_AJH et al. Takemoto_M et al. Zhu_J et al.
The biosynthesis of clavulones is suggested to proceed from arachidonic acid via 8(R)-HEPETE and pre-clavulone A. Corey_EJ Corey_EJ et al. Corey_EJ et al. Corey_EJ et al.
Clavulones showed a significant anti-inflammatory effect at 30 mu g/ml by the fertile egg test. Kikuchi_H et al.Clavulone showed positive chronotropic action on the cultured myocardial cells. Honda_A et al.
