t​2 toxin

T-2 Toxin (T-2 Mycotoxin) 是饲料和谷物中的各种镰刀菌种产生的真菌次生代谢产物，具有很强的生殖毒性，可诱发多种心血管毒性。T-2 Toxin 是一种抑制肽基转移酶 (60s ribosomal 亚基) 结合和蛋白质合成的抑制剂，通过ROS诱导的细胞凋亡诱导TM4细胞功能障碍，抑制 DNA 和 RNA 的合成，增加肝脏脂质过氧化物的水平。

NT 2 Toxin 是一种有用的有机化合物，可用于生命科学领域的相关研究。其产品编号为 T124258，CAS号为 76348-84-0。

HT-2 Toxin, a deacetylated metabolite of T-2 toxin, impairs protein synthesis and hinders cell proliferation in plants.

HT-2 toxin-13C22is intended for use as an internal standard for the quantification of HT-2 toxin by GC- or LC-MS. HT-2 toxin is a type A trichothecene mycotoxin and an active, deacetylated metabolite of the trichothecene mycotoxin T-2 toxin .1,2Like T-2 toxin, HT-2 toxin inhibits protein synthesis and cell proliferation in plants.2HT-2 toxin also reduces viability of HepG2, A549, HEp-2, Caco-2, A-204, U937, Jurkat, and RPMI-8226 cancer cells with IC50values ranging from 3.1 to 23 ng ml and human umbilical vein endothelial cells with an IC50value of 56.4 ng ml.1It induces oxidative stress, DNA damage, and autophagy in, as well as halts the development of, cultured mouse embryos when used at a concentration of 10 nM.3HT-2 toxin has been found in cereal grains and food products.4,5 1.Nielsen, C., Casteel, M., Didier, A., et al.Trichothecene-induced cytotoxicity on human cell linesMycotoxin Res.25(2)77-84(2009) 2.Nathanail, A.V., Varga, E., Meng-Reiterer, J., et al.Metabolism of the fusarium mycotoxins T-2 toxin and HT-2 toxin in wheatJ.
