Rumphellatins B and C, Two New Caryophyllane-Type Hemiketal Norsesquiterpenoids from the Formosan Gorgonian Coral Rumphella antipathies

Two new caryophyllane-type hemiketal norsesquiterpenoid alcohols, designated as rumphellatins B (1) and C (2), were obtained from the Formosan gorgonian coral Rumphella antipathies. The structures of natural products 1 and 2 were established by analyzing the spectral data. Rumphellatin B (1) showed...

Description
Summary:Two new caryophyllane-type hemiketal norsesquiterpenoid alcohols, designated as rumphellatins B (1) and C (2), were obtained from the Formosan gorgonian coral Rumphella antipathies. The structures of natural products 1 and 2 were established by analyzing the spectral data. Rumphellatin B (1) showed antibacterial activity toward the Gram-positive bacterium Staphylococcus aureus.
