生物活性

Cercosporin is produced by a plant pathogen, Pseudocercosporella capsellae. Cercosporin is a potent photosensitizer with a short activation wavelength, mostly suitable for superficial photodynamic therapy (PDT) treatments, especially when it is necessary to avoid perforations[1]. Cercosporin contains the perylenequinone structural features necessary to PKC activity with an IC50 of 0.6-1.3 μM[2].

Cercosporin (0.8-8.0 μM;30 s,60 s,90 s,120 s) 光动力疗法 (PDT) 作用在 T98G 细胞中比在 U87 或 MCF7 细胞中更强,LD50 值对 T98G 细胞 (0.14 J cm2) 远小于 MCF-7 和 U87 细胞系的 LD50 值 (0.26 和 0.24 J cm2)[1]
Cercosporin (0-3 μM;24 小时) 与铜相互作用,在 MCF7 和 T98G 细胞中产生协同细胞毒性,即 S (CuSO4 + Cerco) ? S (CuSO4) x S (Cerco),在 U87 细胞中几乎没有累加效应[1]

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
