ml 204

ML204 是有效的TRPC4 TRPC5通道选择性抑制剂，相比于 TRPC6 ，对TRPC4 TRPC5通道的选择性高出 19 倍，不影响其他的 TRP 通道和电压门控的钠、钾或 Ca2+通道。

ML204 hydrochloride (ML204 HCl) 是一种具有选择性和高效性的 TRPC4 TRPC5 通道拮抗剂，可阻断通过 μ-阿片受体刺激或鸟苷 5'-3-O-（硫代）三磷酸 （GTPgammaS） 的细胞内透析激活的 TRPC4β 电流。

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.
