HT-2 Toxin-13C22 is 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
Pumiliotoxins (PTXs), are one of several toxins found in the skin of poison dart frogs. There are three different types of this toxin: A, B and C, of which toxins A and B are more toxic than C. Pumiliotoxins interfere with muscle contraction by affecting
Cytochalasin C is a cell-permeable fungal toxin that can induce the formation of nuclear sticks. Cytochalasin C is 10 times less toxic than cytochalasin D in mice.
