Applications 1-(2,3-Epoxypropyl)-2-nitroimidazole is an intermediate in the synthesis of Pimonidazole-d10 (P447814). Isotope labelled Pimonidazole (P447813) is an effective and nontoxic hypoxia detection reagent. Pimonidazole forms adducts with thiol groups in proteins, peptides and amino acids. It abels hypoxic tumor cells in vivo. Also labels hypoxic mesenchymal stem cells in mouse bone marrow.

Stability Desiccate and Store at -20°C
Applications Kifunensine is an alkaloid produced by the fungus, Kitasatosporia kifunense, and has been shown to be a weak inhibitor of aryl mannosidase. It is a unique oxamide derivative of mannojirimycin and a potent inhibitor of the glycoprotein processing enzyme mannosidase I. Kifunenesine is ineffective in inhibiting either mannosidase II or the endoplasmic reticulum (ER) a-mannosidase. It also possesses immunomodulating properties based on chemical, physicochemical and x-ray crystallographic analysis.When tested in cell culture using influenza virus-infected MDCK cells, kifunensine, at 1 mg/ml or less, caused almost complete inhibition of complex chain formation with the accumulation of Man9(GlcNAc)2. Thus, kifunensine was proven to be 50 to 100 times more effective than deoxymannojirimycin.Ph

Applications Apatinib is an orally available, small molecule multitargeted tyrosine kinase inhibitor. Apatinib selectively inhibits the vascular endothelial growth factor receptor-2 (VEGFR2). Apatinib functions by inhibiting VEGF-mediated endothelial cell migration and proliferation thus blocking new blood vessel formation in tumor tissue. Recent studies have shown that Apatinib enhances the efficacy of conventional chemotherapeutical drugs in side population (SP) cells and ABCB1-overexpressing leukemia cells.
