Camalexin 是一种植物抗毒素,是从Camelina sativa(十字花科植物)中分离出来的,具有抗菌,抗真菌,抗增殖和抗癌活性。Camalexin 可诱导活性氧 (ROS) 的产生。
生物活性 | Camalexin is a phytoalexin isolated fromCamelina sativa(Cruciferae) with antibacterial, antifungal, antiproliferative and anticancer activities. Camalexin can inducereactive oxygen species(ROS)production[1][2][3]. |
IC50& Target | Reactive oxygen species (ROS)[1][2] |
体外研究 (In Vitro) | Camalexin shows antiproliferative activity against a human breast cancer cell line[2]. For the oomycetesPhytophthoraandPythiumNep1-like proteins (necrosis and ethylene-inducing peptide 1-like proteins) are the initial triggers of Camalexin synthesis and formation of reactive oxygen species (ROS). ROS appear to be of general relevance for Camalexin formation. Chemical induction of ROS, such as by application of acifluorfen, coincided with Camalexin synthesis. In a screen for enhanced susceptibility toAlternaria brassicicolatheesa1mutant is identified, which shows delayed Camalexin induction. Particularly in response to ROS inducing agents reduced Camalexin levels are synthesized. This crucial role forESA1is confirmed by the inability ofesa1mutants to synthesize Camalexin in response toLeptosphaeria maculans. An additional mutant that exhibits greatly reduced Camalexin accumulation isups1, which is isolated on the basis of diminished expression of a tryptophan biosynthetic enzyme[2].
