Application

尾孢菌素(C29H26O10)是一种从香蕉病原体培养物中分离出来的红色色素。它已被用于研究野油菜黄单胞菌百日菊致病变种(Bacterium Xanthomonas campestris pv. Zinniae )等物种的毒素生物降解

Biochem/physiol Actions

头孢菌素是一种聚酮化合物植物毒素,可以被光激活,并在激活状态下与氧气反应生成有毒氧物种,例如单线态氧(O2)和超氧化物(O2-)。活性氧的产生导致植物细胞膜中脂质的过氧化。
据报道,光诱导的聚酮化合物植物毒素在光催化下会产生单线态氧。

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
