  abstract = {{R}eported here are the novel free corallistin {B}, {C}, {D}, and {E}, isolated as methyl esters 2a, 3a, 4a, and 5a, respectively, from the sponge #{C}orallistes$ sp.(#{L}ithistida$) collected at the basis of the {S}outh {N}ew {C}aledonian coral reef. {A} protocol is also established for formulation of their {N}i{II} complexes, which show a different reactivity pattern toward {DMF}/{POCI}3 from metal complexes of deuteroporphyrin {IX} (isolate as 6a) also present in the sponge, the new corallistins, which may be thought to derive from protoporphyrin via heme, account for an amazing 60% of the et{OH} extract from the sponge.
