Camalexin

Camalexin用途

Camalexin 是一种植物抗毒素,是从 Camelina sativa 和 Arabidopsis(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。

CAMILIXIN对人乳腺癌细胞系显示抗增殖活性〔2〕。对于oomycetes Phytophthora和腐霉NEP1样蛋白(坏死和乙烯诱导肽1样蛋白)是辣椒素合成和活性氧物种(ROS)形成的最初触发物。ROS似乎是樟脑素形成的普遍相关性。ROS的化学诱导,如应用氟虫胺,与樟脑素合成一致。在一个屏幕上,以增强对Alternaria油菜的敏感性,ESA1突变体被鉴定,显示延迟的樟脑素诱导。特别是响应于ROS诱导剂,合成樟脑素水平降低。ESA1的这一关键作用是由ESA1突变体不能响应于马尾松钩端螺旋体合成樟脑苷酸而证实的。一个额外的突变体,显示大大减少樟脑素积累是UPS1,这是孤立的基础上减少色氨酸生物合成酶的表达〔2〕。
