CAS:1-(2-Furoyl)piperazine is a potent inhibitor of tyrosinase, an enzyme involved in the production of melanin. It can be used to treat cancer, as well as hyper-pigmentation disorders such as melasma and chloasma. 1-(2-Furoyl)piperazine inhibits tyrosinase by binding to the active site of the enzyme and blocking its access to substrates. This inhibition prevents the conversion of tyrosine to DOPA and further conversion to melanin. 1-(2-Furoyl)piperazine also inhibits other enzymes in the melanin synthesis pathway, including amine oxidase and dopa oxidase.Formula:C9H12N2O2Purity:Min. 95%Color and Shape:PowderMolecular weight:180.2 g/mol1H-Pyrrolo[3,2-c]pyridine, 4-chloro-1-(phenylsulfonyl)-

CAS:Formula:C10H12D3NOMolecular weight:168.25L-Homocysteinesulfinic acid
CAS:L-Homocysteinesulfinic acid is an endogenous metabolite of the amino acid homocysteine. It is a reactive molecule that has been shown to cause neuronal death in vitro and in vivo. L-Homocysteinesulfinic acid binds to the NMDA receptor and inhibits its function, which may cause apoptosis. L-Homocysteinesulfinic acid also binds to the alpha2-adrenergic receptor and enhances uptake of glutamate, thereby causing neuronal death. L-Homocysteinesulfinic acid has been shown to be elevated in cancer patients, as well as those with a high risk for developing cancer. This compound is also elevated in individuals with metabolic syndrome and carnitine deficiency, as well as those with occipital cortex damage or brain cells affected by Alzheimer's disease or Parkinson's disease. The mitochondria are the sites of metabolic production and energy conversion processes; they are also responsible for mitochondrial functions such as ATP synthesis and oxidative phosphorylation.Formula:C4H9NO4SPurity:Min. 95%Molecular weight:167.19 g/mol[4-(4-Amino-7-hydroxy-6-methoxy-2-quinazolinyl)-1-piperazinyl](tetrahydro-2-furanyl)-methanone

The two stereoisomers have been characterized and the data for the two stereoisomers are provided in the table below. The data show that DMQA has high purity (>98%) and good stability at room temperature. DMQA is relatively stable under acidic conditions and can be used as an impurity standard in drug product manufacturing process monitoring.Formula:C18H23N5O4Purity:Min. 95%Molecular weight:373.41 g/molRef: 4Z-A-143013
