Aplicación

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 .

Acciones bioquímicas o fisiológicas

A light-induced polyketide phytotoxin reported to produce singlet oxygen when photoactivated.
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.

Cercosporin is a non-host-selective, photoactivated polyketide toxin produced by many phytopathogenic Cercospora species, which plays a crucial role during pathogenesis on host plants. Upon illumination, cercosporin converts oxygen molecules to toxic superoxide and singlet oxygen that damage various cellular components

The malaria parasite Plasmodium falciparum proliferates within human erythrocytes and is thereby exposed to a variety of reactive oxygen species (ROS) such as hydrogen peroxide, hydroxyl radical, superoxide anion, and highly reactive singlet oxygen ((1)O(2)). While most ROS are already

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
