Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 10239-34-6, molcular formula is C17H22N2, introducing its new discovery. Product Details of 10239-34-6
Human myeloperoxidase (MPO) plays an important role in innate immunity but also aggravates tissue damage by oxidation of biomolecules at sites of inflammation. As a result from a recent high-throughput virtual screening approach for MPO inhibitors, bis-2,2?-[(dihydro-1,3(2H,4H) pyrimidinediyl)bis(methylene)]phenol was detected as a promising lead compound for inhibition of the MPO-typical two-electron oxidation of chloride to hypochlorous acid (IC50= 0.5 muM). In the present pharmacomodulation study, 37 derivatives of this lead compound were designed and synthesized driven by comprehensive docking studies and the impact on the chlorination activity of MPO. We describe the structural requirements for optimum (i) binding to the heme periphery and (ii) inhibition capacity. Finally, the best three inhibitors (bis-arylalkylamine derivatives) were probed for interaction with the MPO redox intermediates Compound I and Compound II. Determined apparent bimolecular rate constants together with determination of reduction potential and nucleophilicity of the selected compounds allowed us to propose a mechanism of inhibition. The best inhibitor was found to promote the accumulation of inactive form of MPO-Compound II and has IC50= 54 nM, demonstrating the successful approach of the drug design. Due to the similarity of ligand interactions between MPO and serotonine transporter, the selectivity of this inhibitor was also tested on the serotonin transporter providing a selectivity index of 14 (KiSERT/IC50MPO).
