Lu, Tong published the artcileDesign and synthesis of C-ring quinoxaline-substituted sinomenine 1,2,3-triazole derivatives via click reactions, Related Products of chlorides-buliding-blocks, the publication is Journal of Chemical Research (2020), 44(11-12), 699-704, database is CAplus.

The synthesis of C-ring quinoxaline-substituted sinomenine 1,2,3-triazole derivatives at the 4-OH via click reactions was accomplished, and a total of 16 novel sinomenine double N-heterocyclic derivatives are obtained in 74%-95% yields. The C-ring is first transformed into a 1,2-diketone structure under the action of hydrochloric acid, and then reacted with o-phenylenediamine to obtain a C-ring quinoxaline-substituted structure. The 4-OH of sinomenine reacted with chloropropyne to give an alkynyl sinomenine, and then reacts with sodium azide and various benzyl chlorides to give the target compounds All the synthesized derivatives were characterized by Fourier-transform IR spectrometry, high resolution mass spectrometry, ¹H NMR, and ¹³C NMR spectroscopy.

An efficient Chan-Lam-type methodol. for the selective synthesis of S-arylbenzimidazoles and N,S-diarylbenzimidazoles was developed. The selectivity was controlled by varying the amount of the catalyst Cu(OAc)₂·H₂O, temperature, and solvent switching. These transformations feature a simple protocol, broad functional group tolerance, high selectivity, and good to excellent yields. It is noteworthy that these reactions represent the first examples of the application of the selective Chan-Lam coupling.

Kemp, Laura R. published the artcileThe transcriptional regulator CprK detects chlorination by combining direct and indirect readout mechanisms, Computed Properties of 33697-81-3, the publication is Philosophical Transactions of the Royal Society, B: Biological Sciences (2013), 368(1616), 20120323/1-20120323/8, database is CAplus and MEDLINE.

The transcriptional regulator CprK controls the expression of the reductive dehalogenase CprA in organohalide-respiring bacteria. Desulfitobacterium hafniense CprA catalyzes the reductive dechlorination of the terminal electron acceptor o-chlorophenol acetic acid, generating the phenol acetic acid product. It has been shown that CprK has ability to distinguish between the chlorinated CprA substrate and the de-halogenated end product, with an estimated an estimated 10⁴-fold difference in affinity. Using a green fluorescent protein GFP_UV-based transcriptional reporter system, we establish that CprK can sense o-chlorophenol acetic acid at the nanomolar level, whereas phenol acetic acid leads to transcriptional activation only when approaching micromolar levels. A structure-activity relationship study, using a range of o-chlorophenol acetic-acid-related compounds and key CprK mutants, combined with pK_a calculations on the effector binding site, suggests that the sensitive detection of chlorination is achieved through a combination of direct and indirect readout mechanisms. Both the phys. presence of the bulky chloride substituent as well as the accompanying electronic effects lowering the inherent phenol pK_a are required for high affinity. Indeed, transcriptional activation by CprK appears strictly dependent on establishing a phenolate-K133 salt bridge interaction, rather than on the presence of a halogen atom per se. As K133 is strictly conserved within the CprK family, our data suggest that physiol. function and future applications in biosensing are probably restricted to phenolic compounds

Cid, Jose Maria published the artcileDiscovery of 1,4-Disubstituted 3-Cyano-2-pyridones: A New Class of Positive Allosteric Modulators of the Metabotropic Glutamate 2 Receptor, Category: chlorides-buliding-blocks, the publication is Journal of Medicinal Chemistry (2012), 55(5), 2388-2405, database is CAplus and MEDLINE.

The discovery and characterization of compound 48, a selective and in vivo active mGlu2 receptor pos. allosteric modulator (PAM), are described. A key to the discovery was the rational exploration of the initial HTS hit 13 guided by an overlay model built with reported mGlu2 receptor PAM chemotypes. The initial weak in vitro activity of the hit 13 was quickly improved, although compounds still had suboptimal druglike properties. Subsequent modulation of the physicochem. properties resulted in compounds having a more balanced profile, combining good potency and in vivo pharmacokinetic properties. Final refinement by addressing cardiovascular safety liabilities led to the discovery of compound (I). Besides good potency, selectivity, and ADME properties, I displayed robust in vivo activity in a sleep-wake EEG (sw-EEG) assay consistent with mGlu2 receptor activation, in accordance with previous work from our laboratories

Toader, Gabriela published the artcileEco-Friendly Peelable Active Nanocomposite Films Designed for Biological and Chemical Warfare Agents Decontamination, Safety of 1,2-Bis(2-chloroethyl)disulfane, the publication is Polymers (Basel, Switzerland) (2021), 13(22), 3999, database is CAplus and MEDLINE.

In the context of imminent threats concerning biol. and chem. warfare agents, the aim of this study was the development of a new method for biol. and chem. decontamination, employing non-toxic, film-forming, water-based biodegradable solutions, using a nano sized reagent together with bentonite as trapping agents for the biol. and chem. contaminants. Bentonite-supported nanoparticles of Cu, TiO₂, and Ag were successfully synthesized and dispersed in a polyvinyl alc. (PVA)/glycerol (GLY) aqueous solution The decontamination effectiveness of the proposed solutions was evaluated by qual. and quant. anal. techniques on various micro-organisms, with sulfur mustard (HD) and di-Me methylphosphonate (DMMP) as contaminants. The results indicate that the peelable active nanocomposite films can be successfully used on contaminated surfaces to neutralize and entrap the hazardous materials and their degradation products. Mech. and thermal characterization of the polymeric films was also performed to validate the decontamination solution′s potential as peelable-film generating materials. The removal efficacy from the contaminated surfaces for the tested micro-organisms varied between 93% and 97%, while for the chem. agent HD, the highest decontamination factor obtained was 90.89%. DMMP was almost completely removed from the contaminated surfaces, and a decontamination factor of 99.97% was obtained.

Stanford, Stephanie M. published the artcileDiscovery of Orally Bioavailable Purine-Based Inhibitors of the Low-Molecular-Weight Protein Tyrosine Phosphatase, SDS of cas: 620-20-2, the publication is Journal of Medicinal Chemistry (2021), 64(9), 5645-5653, database is CAplus and MEDLINE.

Obesity-associated insulin resistance plays a central role in the pathogenesis of type 2 diabetes. A promising approach to decrease insulin resistance in obesity is to inhibit the protein tyrosine phosphatases that neg. regulate insulin receptor signaling. The low-mol.-weight protein tyrosine phosphatase (LMPTP) acts as a critical promoter of insulin resistance in obesity by inhibiting phosphorylation of the liver insulin receptor activation motif. Here, we report development of a novel purine-based chem. series of LMPTP inhibitors. These compounds inhibit LMPTP with an uncompetitive mechanism and are highly selective for LMPTP over other protein tyrosine phosphatases. We also report the generation of a highly orally bioavailable purine-based analog that reverses obesity-induced diabetes in mice.

Broekhuysen, J. published the artcileAnalytical separation of various betaines and quaternary ammonium derivatives by paper electrorheophoresis, COA of Formula: C7H16ClNO2, the publication is Annales de Biologie Clinique (1961), 533-47, database is CAplus and MEDLINE.

Data are given on the electrophoretic behavior on paper of the betaine from crotonic acid and Me₃N, glycine betaine, γ-butyrobetaine, carnitine, choline, creatine, creatinine, Et ester of carnitine, β-homocholine, neurine, phosphocholine, phosphoethanolamine, tetramethylammonium ion, and Me₃N⁺. The elec. mobility was demonstrated to be a simple function of the specific charge on the ion, a relation which holds also for closely related compounds such as creatine and creatinine which were separated sharply by electrorheophoresis. The specific charges differed greatly at different pH values. It was possible, when dissociation constants were known, to determine the pH for optimum separation of the different compounds The advantage of electrorheophoresis is that the rate of migration may be modified by changing the ionic force of the buffer used without altering the pH. The method is applicable to the separation of substances of biol. origin from attendant impurities.
