  Jaspines A and B: two new cytotoxic sphingosine derivatives from the marine sponge Jaspis sp.

  摘要：

  The ethanolic extract of the sponge Jaspis sp. collected in Vanuatu showed cytotoxicity against KB tumour cells (IC95 = 10 mug/ml). A bioassay-guided fractionation led to the isolation of two new cytotoxic sphingosine derivatives, jaspine A and jaspine B. Structures were elucidated by spectroscopic methods, and absolute configuration by chemical derivatisation. The cytotoxicity of jaspine B hydrochloride was evaluated against the A549 lung tumour cell line (IC50 = 3.4 x 10(-7) M). (C) 2002 Elsevier Science Ltd. All rights reserved.
