The author of the article were Beatty, Joel W.; Lindsey, Erick A.; Thomas-Tran, Rhiannon; Debien, Laurent; Mandal, Debashis; Jeffrey, Jenna L.; Tran, Anh T.; Fournier, Jeremy; Jacob, Steven D.; Yan, Xuelei; Drew, Samuel L.; Ginn, Elaine; Chen, Ada; Pham, Amber T.; Zhao, Sharon; Jin, Lixia; Young, Stephen W.; Walker, Nigel P.; Leleti, Manmohan Reddy; Moschutz, Susanne; Strater, Norbert; Powers, Jay P.; Lawson, Kenneth V.. The article conveys some information:
CD73 is an extracellular mediator of purinergic signaling. When upregulated in the tumor microenvironment, CD73 has been implicated in the inhibition of immune function through overproduction of adenosine. Traditional efforts to inhibit CD73 have involved antibody therapy or the development of small mols., the most potent of which mimic the acidic and ionizable structure of the enzyme’s natural substrate, AMP (AMP). Here, we report the systematic discovery of a novel class of non-nucleotide CD73 inhibitors that are more potent than all other nonphosphonate inhibitor classes reported to date. These efforts have culminated in the discovery of 4-({5-[4-fluoro-1-(2H-indazol-6-yl)-1H-1,2,3-benzotriazol-6-yl]-1H-pyrazol-1-yl}methyl)benzonitrile (73, IC50 = 12 nM) and 4-({5-[4-chloro-1-(2H-indazol-6-yl)-1H-1,2,3-benzotriazol-6-yl]-1H-pyrazol-1-yl}methyl)benzonitrile (74, IC50 = 19 nM). Cocrystn. of 74 with human CD73 demonstrates a competitive binding mode. These compounds show promise for the improvement of drug-like character via the attenuation of the acidity and low membrane permeability inherent to known nucleoside inhibitors of CD73. In the experimental materials used by the author, we found 1-Methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole(cas: 847818-74-0Application In Synthesis of 1-Methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole)
1-Methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole(cas: 847818-74-0) belongs to pyrazoles. Pyrazoles are commonly used scaffold molecules in drug discovery projects. The use of pyrazole derivatives is based on their analgesic, neuroleptic, anticonvulsant, monoamine oxidase inhibitory, anti-inflammatory, antipyretic, antiarrhythmic, sedative, muscle relaxant, antidiabetic and antibacterial activities.
