Rein, Jonas;Annand, James R.;Wismer, Michael K.;Fu, Jiantao;Siu, Juno C.;Klapars, Artis;Strotman, Neil A.;Kalyani, Dipannita;Lehnherr, Dan;Lin, Song research published 《 Unlocking the Potential of High-Throughput Experimentation for Electrochemistry with a Standardized Microscale Reactor》, the research content is summarized as follows. Organic electrochem. has emerged as an enabling and sustainable technol. in modern organic synthesis. Despite the recent renaissance of electrosynthesis, the broad adoption of electrochem. in the synthetic community, and especially in industrial settings, has been hindered by the lack of general, standardized platforms for high-throughput experimentation (HTE). Herein, we disclose the design of the HTe^–Chem, a high-throughput microscale electrochem. reactor that is compatible with existing HTE infrastructure and enables the rapid evaluation of a broad array of electrochem. reaction parameters. Utilizing the HTe^–Chem to accelerate reaction optimization, reaction discovery, and chem. library synthesis is illustrated using a suite of oxidative and reductive transformations under constant current, constant voltage, and electrophotochem. conditions.

Ethyl pyrazole-4-carboxylate is a low yield, transition metal salt that is used in the synthesis of pyrazoles. It can be synthesized by the reaction of sodium ethoxide with ethyl chloroformate and a Grignard reagent. Sodium ethoxide is added to a suspension of sodium chloride and dried ethyl chloroformate, followed by addition of magnesium turnings. The mixture is refluxed for one hour, cooled, and filtered to give crystals. Ethyl pyrazole-4-carboxylate is used in the preparation of ethyl esters from aliphatic alcohols by reacting with boron trichloride or phosphorus pentachloride.

Examination of structure-activity relationships and preliminary assessment identified I (R¹ = 1-methyl-1H-pyrazol-4-yl) as a novel FGFR inhibitor that displayed excellent potency in vitro. Candidate I [R¹ = 1-methyl-1H-pyrazol-4-yl (III)] suppressed the phosphorylation of FGFR signaling pathways and induced cell cycle arrest and apoptosis at low nanomolar concentration In the kinase inhibition profile, III showed excellent kinase selectivity for the FGFR family. Furthermore, III showed higher aqueous solubility than Erdafitinib. Moreover, III exhibited potent antitumor activity (tumor growth inhibition = 106.4%) in FGFR2-amplified SNU-16 gastric cancer xenograft model using a daily oral dose of 30 mg/kg. These results suggest that III is a promising candidate for further drug development.

Signaling via the receptor tyrosine kinase CSF1R is thought to play an important role in recruitment and differentiation of tumor-associated macrophages (TAMs). TAMs play pro-tumorigenic roles, including the suppression of anti-tumor immune response, promotion of angiogenesis and tumor cell metastasis. Because of the role of this signaling pathway in the tumor microenvironment, several small mol. CSF1R kinase inhibitors are undergoing clin. evaluation for cancer therapy, either as a single agent or in combination with other cancer therapies, including immune checkpoint inhibitors. Herein the authors describe the authors’ lead optimization effort that resulted in the identification of a potent, cellular active and orally bioavailable bis-amide CSF1R inhibitor. Docking and biochem. anal. allowed the removal of a metabolically labile and poorly permeable Me piperazine group from an early lead compound Optimization led to improved metabolic stability and Caco2 permeability, which in turn resulted in good oral bioavailability in mice.

Powell, Chelsea E.;Hatcher, John M.;Jiang, Jie;Vatsan, Prasanna S.;Che, Jianwei;Gray, Nathanael S. research published 《 Selective Macrocyclic Inhibitors of DYRK1A/B》, the research content is summarized as follows. Dual-specificity tyrosine-(Y)-phosphorylation regulated kinase 1A (DYRK1A) is a therapeutic target of interest due to the roles it plays in both neurol. diseases and cancer. We present the development of the first macrocyclic inhibitors of DYRK1A. Initial lead inhibitor JH-XIV-68-3 (3) displayed selectivity for DYRK1A and close family member DYRK1B in biochem. and cellular assays, and demonstrated antitumor efficacy in head and neck squamous cell carcinoma (HNSCC) cell lines. However, we noted that it suffered from rapid aldehyde oxidase (AO)-mediated metabolism To overcome this liability, we generated a derivative (JH-XVII-10 (10)), where fluorine was introduced to block the 2-position of the azaindole and render the mol. resistant to AO activity. We showed that 10 maintains remarkable potency and selectivity in biochem. and cellular assays as well as antitumor efficacy in HNSCC cell lines and improved metabolic stability. Therefore, 10 represents a promising new scaffold for developing DYRK1A-targeting chem. probes and therapeutics.

Polunin, K. E.;Ul′yanov, A. V.;Polunina, I. A.;Buryak, A. K. research published 《 Detection and Neutralization of Unsymmetrical Dimethylhydrazine on the Surface of Construction Materials》, the research content is summarized as follows. The construction materials that contacted with unsym. dimethylhydrazine and the desorption solutions obtained when treating the contaminated surface of metals and alloys with water and reagents were studied by chromatog. and mass spectrometry.

Nucleophilic aromatic substitution (S_NAr) is a classical reaction with well-known reactivity toward electron-poor fluoroarenes. However, electron-neutral and electron-rich fluoro(hetero)arenes are considerably underrepresented. Herein, we present a method for the nucleophilic defluorination of unactivated fluoroarenes enabled by cation radical-accelerated nucleophilic aromatic substitution. The use of organic photoredox catalysis renders this method operationally simple under mild conditions and is amenable to various nucleophile classes, including azoles, amines, and carboxylic acids. Select fluorinated heterocycles can be functionalized using this method. In addition, the late-stage functionalization of pharmaceuticals is also presented. Computational studies demonstrate that the site selectivity of the reaction is dictated by arene electronics.

Multiparameter optimization included securing adequate potency in human whole blood, navigation away from Ames mutagenic amine fragments while balancing metabolic stability and PK properties allowing for clin. relevant exposures after oral dosing. The superior safety profile of AZD5718 compared to earlier front-runner compounds allowed us to perform a phase 1 clin. study in which AZD5718 demonstrated a dose dependent and greater than 90% suppression of leukotriene production over 24 h. Currently, AZD5718 is evaluated in a phase 2a study for treatment of coronary artery disease.
