Pyrazoles can be selectively lithiated at different carbons and subsequently react with electrophiles depending on the substitution patterns. 269410-08-4, formula is C9H15BN2O2, Name is 4-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole. 1-Methyl-5-(trifluoromethyl)pyrazole underwent deprotonation and subsequent carboxylation mainly or exclusively at either the 4-position of the heterocycle or at the nitrogen-attached methyl group. Name: 4-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole.
Choi, Chang-Ju;Kim, Mira;Han, Sun Young;Jeon, Jiyoung;Lee, Jae Ho;Oh, Jeong-In;Suh, Kwee Hyun;Suh, Dong-Churl;Lee, Kwang-Ok research published 《 Discovery of a Novel HDAC3 Selective Inhibitor and its Evaluation in Lymphoma Model》, the research content is summarized as follows. Histone deacetylase (HDAC) inhibition is a potentially attractive approach to cancer therapy. A number of HDAC inhibitors are in clin. development stages for the treatment of cancer as well as immune and inflammatory disorders. Although there are several approved HDAC inhibitors by the US FDA, they show a broad inhibitory spectrum against HDAC subfamily. Herein, we synthesized a series of novel hydroxamate analogs, and evaluated them with lymphoma cancer cell. Conclusively, we identified an HDAC3 selective inhibitor which shows good anticancer activity for the lymphoma model, as well as a good drug metabolism and pharmacokinetics (DMPK) profile.
Name: 4-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole, 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.

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