Newpentacyclic sesterterpenes, lintenolide A (2 a, b) and lintenolide B (3 a, b), have been characterized from the caribbean spongeCacospongia cf. linteiformis. The structure elucidation of these compounds was accomplished by using 2D NMR experiments, including 1H-1H (COSY), 1H-13C (HETCORR and COLOC) and rotating frame NOE (ROESY). Compounds showed high ichthyotoxicity and antifeedant activity,
