Calyculins are natural products originally isolated from the marine sponge Discodermia calyx.[2] Calyculins have proven to be strong serine/threonine protein phosphatase inhibitors and based on this property, calyculins might be potential tumor-promoting agents.

A laboratory synthesis of calyculin A has been reported.[3]

Biosynthesis

[edit]

Calyculin A is biosynthesized as a pyrophosphate containing phosphocalyculin A protoxins by a hybrid PKS-NRPS pathway within the sponge bacterial symbiont, "Candidatus Entotheonella" sp.[4]
