Coral reefs are the most biodiverse and biologically productive of all marine ecosystems. Corals harbor diverse and abundant prokaryotic groups. However, little is known about the diversity of coral-associated microorganisms. We used molecular techniques to identify and compare the culturable
This review reports the structural diversity of steroids from Sarcophyton species based on literature from the beginning of marine steroid research until now. There are 65 compounds studied from eight species. Most of them are polyhydroxy-type steroids of C-27-C-31 carbon skeleton. Their biological
Active compounds from natural products have been widely studied. The anti-tumor effects of 13-acetoxysarcocrassolide isolated from Formosan soft coral Sarcophyton crassocaule on bladder cancer cells were examined in this study. An MTT assay showed that 13-acetoxysarcocrassolide was cytotoxic to
Seven new polyoxygenated steroids (1-7) were isolated together with seven known analogues (8-14) from the South China Sea soft coral, Sarcophyton sp. The structures of the new compounds were identified on the basis of extensive spectroscopic analysis and comparison with reported data. All the
