C17 Ceramide is a synthetic ceramide that contains a non-natural C17:0 fatty acid acylated to sphingosine. It has been used as a marker of arylsulfatase A and sphingolipid activator B activity in patients undergoing enzyme replacement therapy for the genetic disease metachromatic leukodystrophy.
C17 Globotriaosylceramide is a sphingolipid that has been used as an internal standard for the quantification of globotriaosylceramides in plasma and urine from patients with Fabry disease by GC-MS.
C17 Lactosylceramide is a naturally occurring sphingolipid that has been found in human brain metastases of lung adenocarcinomas but not in healthy brain tissue.
3-Acetyldeoxy nivalenol-13C17is intended for use as an internal standard for the quantification of 3-acetyldeoxy nivalenol by GC- or LC-MS. 3-Acetyldeoxy nivalenol is a mycotoxin that has been found inF. graminearum.1In vivo, 3-acetyldeoxy nivalenol (40 mg kg) induces duodenal and splenic cell necrosis, as well as lethality (LD50= 70 mg kg) in mice.2 1.Jiao, F., Kawakami, A., and Nakajima, T.Effects of different carbon sources on trichothecene production and Tri gene expression by Fusarium graminearum in liquid cultureFEMS Microbiol.Lett.285(2)212-219(2008) 2.Schiefer, H.B., Nicholson, S., Kasali, O.B., et al.Pathology of acute 3-acetyldeoxynivalenol toxicity in miceCan.

Aflatoxin B2-13C17(AFB2-13C17) is intended for use as an internal standard for the quantification of AFB2by GC- or LC-MS. AFB2is a mycotoxin that has been found inA. terricola.1It induces hepatic autophagy and apoptosis in broiler chickens when administered at doses of 0.2, 0.4, and 0.8 mg kg.2AFB2(0.5 and 1 mg animal) also induces parenchymal cell hyperplasia in rats.3 1.Moubasher, A.H., el-Kady, I.A., and Shoriet, A.Toxigenic Aspergilli isolated from different sources in EgyptAnn.

Aflatoxin G1-13C17is intended for use as an internal standard for the quantification of aflatoxin G1by GC- or LC-MS. Aflatoxin G1is a mycotoxin that has been found inA. terricola.1In vivo, aflatoxin G1is lethal to ducklings (LD50= 1.18 mg kg).2It induces hepatocellular carcinoma tumor formation and lethality in rats when administered at doses of 1.4 and 3 mg animal, respectively. Aflatoxin G1also inhibits liver and kidney succinate dehydrogenase and fumarase, as well as kidney cytochrome oxidase, NADH oxidase, α-glycerophosphate dehydrogenase, isocitrate dehydrogenase, and malate dehydrogenase in rats.3 1.Moubasher, A.H., el-Kady, I.A., and Shoriet, A.Toxigenic Aspergilli isolated from different sources in EgyptAnn.

Aflatoxin G2-13C17is intended for use as an internal standard for the quantification of aflatoxin G2by GC- or LC-MS. Aflatoxin G2is a mycotoxin that has been found inAspergillus.1It is lethal to ducklings (LD50= 2.83 mg kg) but is non-toxic to rats when administered at a dose of 200 mg kg.2 1.Bennett, J.W., and Klich, M.MycotoxinsClin.

CAY17c is an inhibitor of bromodomain-containing protein 4 (BRD4; IC50= 0.71 μM), as well as class I histone deacetylases (HDACs; IC50s = 0.046, 0.058, 0.075, and 0.167 μM for HDAC1, -2, -3, and -8, respectively) and class IIb HDACs (IC50s = 0.073 and 0.923 μM for HDAC6 and HDAC10, respectively).1It is selective for these enzymes over BRD2, -3, and -T (IC50s = >20 μM for all), as well as over HDAC4, -5, -7, -9, and -11 (IC50s = >10 μM for all). CAY17c inhibits the proliferation of HCT116, SW620, and DLD-1 colorectal cancer cells (IC50s = 0.45, 1.78, and 2.11 μM, respectively), as well as induces apoptosis and autophagy in HCT116 cells. It reduces tumor growth in an HCT116 mouse xenograft model when administered at doses of 15 and 30 mg/kg. 1.Pan, Z., Li, X., Wang, Y., et al.Discovery of thieno[2,3-d]pyrimidine-based hydroxamic acid derivatives as bromodomain-containing protein 4/histone deacetylase dual inhibitors induce autophagic cell death in colorectal carcinoma cellsJ.
