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

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. (Résumé d'auteur
