一般建议 | 为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同厂家不同批次产品溶解度各有差异,仅做参考。若实验所需浓度过大至产品溶解极限,请添加助溶剂助溶或自行调整浓度。溶液形式一般不宜长期储存,请尽快用完。 |
Tryptanthrin, a weakly basic alkaloid tryptophan derivative originally isolated from the dried roots of medicinal indigo plants, has anti-inflammatory and anticancer activities. And, tryptanthrin blocks 5-lipoxygenase (5-LO) and cyclooxygenase-2 (Cox-2) with IC50 values of 600 and 64 nM, respectively.
5-LO and Cox-2 are involved in cancer pathobiology. 5-LO is expressed by a variety of cancer cells including colon, lung, breast, and prostate and promotes cancer cell growth and neo-angiogenesis. Cox-2, overexpressed in cancer cells, promotes tumorigenesis and induces neo-angiogenesis.
In vitro: In human hepatocyte-derived HepG2 cells, tryptanthrin inhibited the reactive oxygen species formation, mitochondrial dysfunction, and cell death triggered by tert-butyl hydroperoxide (tBHP). Furthermore, tryptanthrin reversed the reduction of glutathione (GSH) induced by tBHP. Specifically, nuclear translocation, transactivation of nuclear factor erythroid 2-related factor 2 (Nrf2), and phosphorylation of extracellular signal-regulated kinase (ERK) were evoked by the treatment of tryptanthrin. Additionally, the expression of the heme oxygenase 1 and glutamate was upregulated by tryptanthrin [1].
In vivo: BALB/c (H-2d) mice, intraperitoneally (i.p.) inoculated with leukemia WEHI-3B JCS cells, were injected i.p with tryptanthrin at doses of 0.04 mg/kg, 0.08 mg/kg and 0.16 mg/kg body weight for 5 consecutive days. Tryptanthrin inhibited the growth of WEHI-3B JCS cells in BALB/c mice, and at the dosages of 0.08 mg/kg and 0.16 mg/kg, significant inhibition was seen. Moreover, tryptanthrin, in a dose-dependent fashion, triggered cell cycle arrest of the WEHI-3B JCS cells at G0/G1 phase [2].
