title: New anti-inflammatory 4-methylated steroids from the Formosan soft coral Nephthea chabroli.
abstract: Eight new 4-methylated steroids, nebrosteroids A-H (1-8) were isolated from the acetone solubles of the Formosan soft coral Nephthea chabroli. The structures were elucidated by extensive NMR spectroscopic analysis and their anti-inflammatory activity was measured in vitro.
