CAS:Native Melan-A (26-35) decapeptide derives from the melanocyte lineage-specific protein Melan-A/MART-1, which is expressed in almost 75-100% of primary and metastatic melanomas. The region 26-35 of Melan-A protein acts as an antigenic peptide that is recognized by CD8+ tumor-reactive cytolytic T lymphocytes (CTLs) for designing antigen-specific cancer vaccines1. It has been shown that CD8+ Melan-A-specific CTLs isolated from melanoma patients efficiently lyse the Melan-A-expressing HLA-A*0201+ melanoma cell line. However, CTLs preferentially recognize the Melan-A (26-35) peptide as compared with the Melan-A (27-35) peptide. Moreover, the Melan-A (26-35) A27L analog (ELAGIGILTV) has a higher binding affinity to HLA-A*0201 than the native Melan-A (26-35) peptide (EAAGIGILTV), and consequently displays more potent antigenicity and immunogenicity. It has been reported that the concentration of Melan-A (26-35) A27L analog required to obtain 50% of maximal antigenic activity (EC50) is 0.01nM, whereas that of the native Melan-A (26-35) peptide is 0.25nM1. Therefore, the relative activity of Melan-A (26-35) A27L analog is 25 fold higher than that of the native Melan-A (26-35) peptide. Furthermore, functional competition assay has shown that the concentration of Melan-A (26-35) A27L analog required to achieve 50% inhibition (IC50) of tumor lysis is 2nM, which is 10 fold lower than that of the native Melan-A (26-35) peptide. Regarding peptide stability in human serum, the half-lifes (t1/2) of the native Melan-A (26-35) peptide and the A27L analog are quite similar (45 and 40min, respectively) as measured by HPLC-ESI-MS, but much higher than that of the Melan-A (27-35) nonapeptide (5min).Fórmula:C42H74N10O14Pureza:Min. 95%Peso molecular:943.1 g/mol4,5-Dichloro-2-nitroaniline

CAS:o-Toluoyl chloride is an antidiabetic agent that inhibits the production of glucose by inhibiting the enzyme glucosidase. It also prevents the absorption of glucose in the small intestine and blocks pancreatic alpha-amylase, which is an enzyme that breaks down starch into maltose. The chemical reaction mechanism for o-toluoyl chloride is a substitution reaction with a hydroxyl group and a benzoate, forming a cation channel. This leads to an increase in the intracellular concentration of cations, which can contribute to inflammatory bowel disease. The biological studies have shown that light emission is generated when o-toluoyl chloride reacts with 2-methyl-4-nitrobenzoic acid. This process has been used as a method for detecting this compound.Fórmula:C8H7ClOPureza:Min. 95%Forma y color:Clear LiquidPeso molecular:154.59 g/molAllylpalladium(II) chloride dimer
CAS:Allylpalladium(II) chloride dimer is a homogeneous catalyst that can be used for the asymmetric synthesis of organosilicon compounds. It is an allylation agent and has been shown to react with certain nitrogen-containing compounds to form a palladium nitride complex.
