GW844520 is a potent and selective inhibitor of the cytochrome bc1 complex of mitochondrial electron transport in P. falciparum.

GW848687X, a potent and selective prostaglandin EP1 receptor antagonist, is used for the treatment of inflammatory pain.

GW841819X is an analogue of (+)-JQ1 and a novel inhibitor of BET bromodomains. GW841819X was a single enantiomer but of undefined chirality at the 4-position of the benzodiazepine ring3. GW841819X and JQ1 were recently discovered that bind to the acetyl-lysine binding pocket of BET bromodomains with Kd ranges from 50 to 370 nM [1]. GW841819X bounded to both the individual BD1 and BD2 domains with affinities of 46 and 52.5 nM, respectively. GW841819X-Brd3 interaction was estimated to be around 70 nM4. GW841819X displayed activity in vivo against NUT-midline carcinoma, multiple myeloma, mixed-lineage leukemia, and acute myeloid leukemia1. It also potent induced the ApoA1 reporter gene with an EC50 of 440 nM. It had very little effect on LDL-R luciferase activity at the concentrations at which it induces ApoA1 expression, suggesting that the effect is indeed specific3. GW841819X competed directly with GATA1 site for BD1 binding and also specifically blocked the interaction between Brd3 and acetylated GATA14. Recent findings reported that GW841819X are chose as an interest compound to further develop into potential drugs against diseases including cancer, HIV infection and heart disease2.

PF1070A is a natural cyclic tetrapeptide HDAC Inhibitor through the inhibition of PfHDAC1 catalytic activity, potently inducing the synthesis of metallothionein.

GW841819X is an analogue of (+)-JQ1 and a novel inhibitor of BET bromodomains. GW841819X displayed activity in vivo against NUT-midline carcinoma, multiple myeloma, mixed-lineage leukemia, and acute myeloid leukemia. Bromodomain and extra-terminal (BET) proteins belong to a class of proteins collectively called epigenetic readers . BET bromodomains have emerged as promising drug targets for treatment of cancers

Retelliptine, a DNA topoisomerase II inhibitor, is used potentially for the treatment of cancer.

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.
