Application

Cercosporin (C29H26O10) is a red pigment that has been isolated from cultures of a banana pathogen . It has been used to study toxin biodegredation in species such as Bacterium Xanthomonas campestris pv. Zinniae .

Biochem/physiol Actions

Cercosporin, a polyketide phytotoxin, is activated by light and in the activated state, reacts with oxygen to produce toxic oxygen species such as singlet oxygen (O2) and superoxide (O2-). Production of reactive oxygen species leads to peroxidation of lipids in the plant cell membranes.
A light-induced polyketide phytotoxin reported to produce singlet oxygen when photoactivated.

The total syntheses of the PKC inhibitors (+)-calphostin D, (+)-phleichrome, cercosporin, and 10 novel perylenequinones are detailed. The highly convergent and flexible strategy developed employed an enantioselective oxidative biaryl coupling and a double cuprate epoxide opening, allowing the selective syntheses

Cercosporin is a polyketide phytotoxin produced by many phytopathogenic Cercospora spp. We investigated environmental signals that have elaborate control of cercosporin production. Light is the most critical factor for cercosporin production. Cercospora nicotianae accumulated substantial quantities of cercosporin only when
