Hu, Carol H.;Neissel Valente, Meriah W.;Halpern, O. Scott;Jusuf, Sutjano;Khan, Javed A.;Locke, Gregory A.;Duke, Gerald J.;Liu, Xiaoqin;Duclos, Franck J.;Wexler, Ruth R.;Kick, Ellen K.;Smallheer, Joanne M. research published \u300a Small molecule and macrocyclic pyrazole derived inhibitors of myeloperoxidase (MPO)\u300b, the research content is summarized as follows. Myeloperoxidase (MPO), a critical enzyme in antimicrobial host-defense, has been implicated in chronic inflammatory diseases such as coronary artery disease. The design and evaluation of MPO inhibitors for the treatment of cardiovascular disease are reported herein. Starting with the crystal structure of a triazolopyridine-MPO complex, novel inhibitors were designed incorporating a substituted pyrazole, which allowed for substituents to interact with hydrophobic and hydrophilic patches in the active site. SAR exploration of the substituted pyrazoles led to piperidinylbenzyl-substituted triazolopyridine, which inhibited HOCl production from activated neutrophils with an IC50<\/sub> value of 2.4\u03bcM and was selective for MPO over thyroid peroxidase (TPO). Optimization of alkylation chem. on the pyrazole nitrogen facilitated the preparation of many analogs, including macrocycles designed to bridge two hydrophobic regions of the active site. Multiple macrocyclization strategies were pursued to prepare analogs that optimally bound to the active site, leading to potent macrocyclic MPO inhibitors with TPO selectivity, such as I<\/strong>.<\/p>\n

Safety of 4-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole<\/a>, 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole, also known as 4-Pyrazoleboronic acid pinacol ester , is a useful research compound. Its molecular formula is C9H15BN2O2 and its molecular weight is 194.04 g\/mol. The purity is usually 95%.<\/p>\n

4-Pyrazoleboronic acid pinacol ester is a useful reagent for Suzuki-Miyaura cross-couplings as well as Ruthenium-catalyzed asymmetric hydrogenation. 4-Pyrazoleboronic acid pinacol ester is also a useful reagent for preparing VEGF, Aurora, RHO (ROCK), Janus Kinase 2, c-MET, ALK, S-nitrsoflutathione reductase, CDC7, Acetyl-CoA carboxylase inhibitors.<\/p>\n

4-Pyrazoleboronic acid pinacol ester is used in the preparation of Rho kinase (ROCK) inhibitors as wella s other biologically active compounds.<\/p>\n

4-Pyrazoleboronic acid pinacol ester is an organic compound that is the product of a bifunctional coupling reaction between 4-pyrazolecarboxylic acid and pinacol. It has been shown to inhibit protein S6 kinase, which is involved in the regulation of cell growth and proliferation. This compound has also been shown to be effective against cancer cells, including those that are resistant to conventional chemotherapeutic drugs. 4-Pyrazoleboronic acid pinacol ester may also be used as a precursor for other compounds with pharmaceutical activity., 269410-08-4.<\/p>\n
