Refractive Index
Solubility	Chlorovulones are soluble in MeOH, EtOH, CHCl3, or hexane.
Source	Chlorovulones were isolated from Japanese soft coral, Stolonifer Clavularia viridis Quoy and Gaimard. Iguchi_K et al. Nagaoka_H et al.
Chemical Synthesis	Photoisomerization of chlorovulone I (fluoresent lamp, benzene, 40 hr) gave a mixture of chlorovulones I, II and III. Iguchi_K et al.
Metabolism
Biological Activity	Chlorovulone I showed the strong antiproliferative and cytotoxic activities in himan promyelocytic leukemia (HL-60) ((IC_{50} 0.01 mu g/ml, cytotoxic effect >0.1 mu g/ml). Honda_A et al. Honda_A et al. Iguchi_K et al.Chlorovulone I was entrapped into lipid microspheres of 0.2 mu m diameter to lipo-drug. Daily treatment with lipo-chlorovulone I (1.6 mg/kg/day, i.p.) on days 1 through 5 markedly prolonged the survival time (135% ILS) of mice inoculated with sarcoma 180 as compared with that of corresponding dose of respective free chlorovulone I. Honda_A et al.
