The enzymic evaluation highlighted compound I (R = H; Ar = Ph) as selective NPP1 inhibitor, however, compound I (R = H; Ar = 3-O2NC6H4) was observed as the most potent inhibitor of NPP1 with an IC50 value of 0.80 +/- 0.04μM. Compound I (R = 4-NMe2; Ar = Ph) was found to be the most potent and moderately selective inhibitor of NPP3 (IC50 = 0.55 +/- 0.01μM). Furthermore, in vitro cytotoxicity assays of compounds against MCF-7 and HT-29 cancer cell lines exhibited compound I (R = H; Ar = 3-O2NC6H4) (IC50 = 4.70 +/- 0.67μM), and I (R = 5-Br; Ar = 4-MeC6H4) (IC50 = 1.58 +/- 0.20μM) as the most cytotoxic compounds against MCF-7 and HT-29 cancer cell lines, resp. Both the investigated compounds showed high degree of selectivity towards cancer cells than normal cells (WI-38). Mol. docking studies of selective and potent enzyme inhibitors revealed promising mode of interactions with important binding sites residues of both isoenzymes i.e., Thr256, His380, Lys255, Asn277 residues of NPP1 and His329, Thr205, and Leu239 residues of NPP3. In addition, the most potent antiproliferative agent, compound I (R = 5-Br; Ar = 4-MeC6H4), doesn’t produce hypoglycemia as a side effect when injected to mice which is an addnl. merit of this promising compound After reading the article, we found that the author used Oxetan-3-ol(cas: 7748-36-9Formula: C3H6O2)

Synthetic Route of C9H6O6In 2019 ,《Tunable Redox Chemistry and Stability of Radical Intermediates in 2D Covalent Organic Frameworks for High Performance Sodium Ion Batteries》 was published in Journal of the American Chemical Society. The article was written by Gu, Shuai; Wu, Shaofei; Cao, Lujie; Li, Minchan; Qin, Ning; Zhu, Jian; Wang, Zhiqiang; Li, Yingzhi; Li, Zhiqiang; Chen, Jingjing; Lu, Zhouguang. The article contains the following contents:

Radicals are inevitable intermediates during the charging and discharging of organic redox electrodes. The increase of the reactivity of the radical intermediates is desirable to maximize the capacity and enhance the rate capability but is detrimental to cycling stability. Therefore, it is a great challenge to controllably balance the redox reactivity and stability of radical intermediates to optimize the electrochem. properties with a good combination of high specific capacity, excellent rate capability, and long-term cycle life. Herein, we reported the redox and tunable stability of radical intermediates in covalent organic frameworks (COFs) considered as high capacity and stable anode for sodium-ion batteries. The comprehensive characterizations combined with theor. simulation confirmed that the redox of C-O· and α-C radical intermediates play an important role in the sodiation/desodiation process. Specifically, the stacking behavior could be feasibly tuned by the thickness of 2D COFs, essentially determining the redox reactivity and stability of the α-C radical intermediates and their contributive capacity. The modulation of reversible redox chem. and stabilization mechanism of radical intermediates in COFs offers a novel entry to design novel high performance organic electrode materials for energy storage and conversion.

Application In Synthesis of (3,5-Difluoro-4-nitrophenyl)methanol And the article was included in Journal of Medicinal Chemistry on April 12 ,2012. The article conveys some information:

Structure-based design of a series of cyclic hydroxyethylamine BACE1 inhibitors allowed the rational incorporation of prime- and nonprime-side fragments to a central core template without any amide functionality. The core scaffold selection and the structure-activity relationship development were supported by mol. modeling studies and by x-ray anal. of BACE1 complexes with various ligands to expedite the optimization of the series. The direct extension from P1-aryl- and heteroaryl moieties into the S3 binding pocket allowed the enhancement of potency and selectivity over cathepsin D. Restraining the design and synthesis of compounds to a physicochem. property space consistent with central nervous system drugs led to inhibitors with improved blood-brain barrier permeability. Guided by structure-based optimization, highly potent compounds were obtained, such as I, with enzymic and cellular IC50 values of 2 and 50 nM, resp., and with >200-fold selectivity over cathepsin D. Pharmacodynamic studies in APP51/16 transgenic mice at oral doses of 180 μmol/kg demonstrated significant reduction of brain Aβ levels.

Enantioselective oxidation of racemic phenyl-1,2-ethanediol into (R)-(-)-mandelic acid by a newly isolated Brevibacterium lutescens CCZU12-1 was demonstrated. It was found that optically active (R)-(-)-mandelic acid (e.e.p > 99.9 %) is produced leaving the other enantiomer (S)-(+)-phenyl-1,2-ethanediol intact. Using fed-batch method, a total of 172.9 mM (R)-(-)-mandelic acid accumulated in the reaction mixture after the seventh feed. Moreover, oxidation of phenyl-1,2-ethanediol using calcium alginate-entrapped resting cells was carried out in the aqueous system, and efficient biocatalyst recycling was achieved as a result of cell immobilization in calcium alginate, with a product-to-biocatalyst ratio of 27.94 g (R)-(-)-mandelic acid g-1 dry cell weight cell after 16 cycles of repeated use.

A recombinant Escherichia coli system expressing anti-Prelog stereospecific alc. dehydrogenase from Candida parapsilosis was established as a whole-cell system for catalyzing asym. reduction of aryl ketones to anti-Prelog configured alcs. Using 2-hydroxyacetophenone as the substrate, reaction factors including pH, cell status, and substrate concentration had obvious impacts on the outcome of whole-cell biocatalysis, and xylose was found to be an available auxiliary substrate for intracellular cofactor regeneration, by which (S)-1-phenyl-1,2-ethanediol was achieved with an optical purity of 97%e.e. and yield of 89% under the substrate concentration of 5 g/L. Addnl., the feasibility of the recombinant cells toward different aryl ketones was investigated, and most of the corresponding chiral alc. products were obtained with an optical purity over 95%e.e. Therefore, the whole-cell system involving recombinant stereospecific alc. dehydrogenase was constructed as an efficient biocatalyst for highly enantioselective anti-Prelog synthesis of optically active aryl alcs. and would be promising in the pharmaceutical industry.

An ongoing challenge in trifluoromethylthiolation reactions is the use of less expensive and easily available trifluoromethylthio sources. Herein, we disclose an unprecedented usage of trifluoromethanesulfonic anhydride (Tf2O) as a radical trifluoromethylthiolating reagent. Hydrotrifluoromethylthiolation of unactivated alkenes and alkynes with Tf2O in the presence of PMePh2 and H2O under visible-light photoredox catalysis gave the addition products. The trifluoromethylthio radical (.SCF3) was first formed from Tf2O through a photoredox radical processes and deoxygenative reduction of PMePh2, and H2O serves as the H-atom donor for the hydrotrifluoromethylthiolation reaction. This reaction provides a new strategy for radical trifluoromethylthiolation.
