Marine bioactive steryl esters from the red sea black coral antipathes dichotoma

bstract Two new marine steryl hexadecanoates, 3β-hexadecanoylcholest-5-en-7-one (1) 
and 3β-hexadecanoylcholest-5-en-7β-ol (2), along with seven known compounds, cholest-5-
en-3β-yl-formate (3), thymidine (4), indole-3-carboxaldehyde (5), 3β-hydroxycholest-5-en-7-
one (6), cholesterol (7), 22-dehydrocholestrol (8), and 24-methylenecholesterol (9), were 
isolated from the anthozoan black coral, Antipathes dichotoma. The structures of all isolated 
compounds were determined by interpretation of their spectral data 1D (1 H, 13 C and ...
