Corallistin A, a second example of a free porphyrin from a living organism : isolation from the demosponge #Corallistes$ sp. of the coral see and inhibition of abnormal cells D'Ambrosio Michèle auteur aut IRD Guerriero, A. /Debitus, Cécile auteur aut IRD Ribes Olivier auteur aut IRD Richer de Forges Bertrand auteur aut IRD Pietra F. auteur aut IRD text journalArticle eng text/pdf reformatted digital access It is shown that the demosponge Corallistes sp. (Tetractinomorpha, Lithistida, Corallistidae) collected in the Coral Sea, contains corallistin A, the second example, of a free porphyrin from a living organism. The compound proved to be active against the Kb cell line. In contrast with the geoporphyrins which do not bear any O-atom corallistin A carries two carboxylic groups.
