Abstract

Curacin-A, antillatoxin and kalkitoxin, natural products from the marine cyanobacterium Lyngbya majuscula, were tested for neurotoxicity in primary cultures of rat cerebellar granule neurons. Curacin-A was non-toxic, whereas antillatoxin and kalkitoxin produced concentration-dependent cytotoxicity with LC₅₀ values of 20.1±6.4 and 3.86±1.91 nM, respectively. Antillatoxin neurotoxicity was produced acutely, whereas kalkitoxin caused a delayed neurotoxic response. The cytotoxicity produced by both antillatoxin and kalkitoxin was prevented by the non-competitive NMDA receptor antagonists dextrorphan and MK-801. Copyright (C) 1999 Elsevier Science Ltd.
