Physicochemical Information
[ α ]D -28.9°(C 0.36, 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.
Clavulone I was synthesized from cyclopentadiene and methyl 3-chloroformylpropionate as a racemic form. Corey_EJ et al.Clavulones were synthesized from L-(+)-diethyl tartarate and D-mannitol as a natural form. Nagaoka_H et al.Other synthesis of clavulone. Klunder_AJH et al. Takemoto_M et al. Zhu_J et al.
The biosynthesis of clavulone 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 I showed strong antiproliferative activity in the human myeloid leukemia (HL-60) cells (IC_{50} 0.2 mu g/ml). Clavulone arrests the cells in the G1-phase and inhibits the cell growth of HL-60 cells by inhibiting S-phase DNA synthesis. Honda_A et al.Clavulone showed positive chronotropic action on the cultured myocardial cells. Honda_A et al.
