At the forefront of new synthetic endeavors, such as drug discovery or natural product synthesis, large quantities of material are rarely available and timelines are tight. A miniaturized automation platform enabling high-throughput experimentation for synthetic route scouting to identify conditions for preparative reaction scale-up would be a transformative advance. Because automated, miniaturized chem. is difficult to carry out in the presence of solids or volatile organic solvents, most of the synthetic toolkit cannot be readily miniaturized. Using palladium-catalyzed cross-coupling reactions as a test case, we developed automation-friendly reactions to run in DMSO at room temperature This advance enabled us to couple the robotics used in biotechnol. with emerging mass spectrometry-based high-throughput anal. techniques. More than 1500 chem. experiments were carried out in less than a day, using as little as 0.02 mg of material per reaction. The synthesis of the target compounds was achieved using as starting materials N-(1,1-dimethylethyl)-4′-[(6-iodo-4-oxo-2-propyl-3(4H)-quinazolinyl)methyl][1,1′-biphenyl]-2-sulfonamide, (5R)-3-(3-fluoro-4-iodophenyl)-5-(1H-1,2,3-triazol-1-ylmethyl)-2-oxazolidinone, 7-[(3-bromo-4-methoxyphenyl)methyl]-1-ethyl-3,7-dihydro-8-[[(1R,2R)-2-hydroxycyclopentyl]amino]-3-(2-hydroxyethyl)-1H-purine-2,6-dione. Other reactants included (3R,4S)-3-[[[[3-bromo-5-(3-methoxypropyl)-4-methylphenyl]methyl]cyclopropylamino]carbonyl]-4-(1,2-dihydro-1-methyl-2-oxo-4-pyridinyl)-1-piperidinecarboxylic acid 1,1-dimethylethyl ester, 1-[(4-chlorophenyl)methyl]-3-[(1,1-dimethylethyl)thio]-5-(3-isoquinolinylmethoxy)-α,α-dimethyl-1H-indole-2-propanoic acid Me ester. Amine reactants included 1-piperazinecarboxylic acid Et ester, 1-(aminomethyl)cyclopropanecarboxylic acid ester, carbamic acid 1,1-dimethylethyl ester, 4-fluoro-2-pyridinamine, 2-thiophenesulfonamide, 2-(dimethylamino)acetamide, cyclopropanecarboximidamide, 1-methly-1H-pyrazole-2-ethanol, 2-cyano-N,N-dimethylacetamide, 1-methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole, 2-(ethynyl)pyrazine. A series of catalysts and reagents was evaluated. The experimental part of the paper was very detailed, including the reaction process of 1-Methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole(cas: 847818-74-0Safety 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, monoamine oxidase inhibitory, anti-inflammatory, antipyretic, neuroleptic, anticonvulsant, antiarrhythmic, sedative, muscle relaxant, antidiabetic and antibacterial activities.

The author of the article were Duraiswamy, Athisayamani Jeyaraj; Lee, May Ann; Madan, Babita; Ang, Shi Hua; Tan, Eldwin Sum Wai; Cheong, Wei Wen Vivien; Ke, Zhiyuan; Pendharkar, Vishal; Ding, Li Jun; Chew, Yun Shan; Manoharan, Vithya; Sangthongpitag, Kanda; Alam, Jenefer; Poulsen, Anders; Ho, Soo Yei; Virshup, David M.; Keller, Thomas H.. The article conveys some information:

Wnt proteins regulate various cellular functions and serve distinct roles in normal development throughout life. Wnt signaling is dysregulated in various diseases including cancers. Porcupine (PORCN) is a membrane-bound O-acyltransferase that palmitoleates the Wnts and hence is essential for their secretion and function. The inhibition of PORCN could serve as a therapeutic approach for the treatment of a number of Wnt-dependent cancers. Herein, the authors describe the identification of a Wnt secretion inhibitor from cellular high throughput screening. Classical SAR based cellular optimization provided us with a PORCN inhibitor I with nanomolar activity and excellent bioavailability that demonstrated efficacy in a Wnt-driven murine tumor model. Finally, the authors also discovered that enantiomeric PORCN inhibitors show very different activity in the reporter assay, suggesting that such compounds may be useful for mode of action studies on the PORCN O-acyltransferase. In the part of experimental materials, we found many familiar compounds, such as 1-Methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole(cas: 847818-74-0Application of 847818-74-0)

The author of the article were Le Brazidec, Jean-Yves; Pasis, Angela; Tam, Betty; Boykin, Christina; Wang, Deping; Marcotte, Douglas J.; Claassen, Gisela; Chong, Jer-Hong; Chao, Jianhua; Fan, Junhua; Nguyen, Khanh; Silvian, Laura; Ling, Leona; Zhang, Lin; Choi, Michael; Teng, Min; Pathan, Nuzhat; Zhao, Shuo; Li, Tony; Taveras, Art. The article conveys some information:

This Letter reports the optimization of a pyrrolopyrimidine series as dual inhibitors of Aurora A/B kinases. This series is derived from a pyrazolopyrimidine series previously reported as inhibitors of aurora kinases and CDKs. In an effort to improve the selectivity of this chemotype, we switched to the pyrrolopyrimidine core which allowed functionalization on C-2. In addition, the modeling rationale was based on superimposing the structures of Aurora-A kinase and CDK2 which revealed enough differences leading to a path for selectivity improvement. The synthesis of the new series of pyrrolopyrimidine analogs relied on the development of a different route for the two key intermediates, which led to analogs with both tunable activity against CDK1 and maintained cell potency. The experimental process involved the reaction of 1-Methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole(cas: 847818-74-0Product Details of 847818-74-0)
