摘要：

Echinoclathrines A-C (3 - 5) have been isolated from an Okinawan sponge, Echinoclathria sp. and the structures elucidated by interpretation of spectral data These compounds are a new class of pyridine alkaloids possessing an 4-aryl-2-methylpyridine moiety as a common structural element. Echinoclathrines A and B exhibited weak immunosuppressive activity in a mixed lymphocyte reaction assay. (C) 1999 Elsevier Science Ltd. All rights reserved.
