Liu, Dachuan; Cheng, Xiu; Wang, Ying published the artcile< Design, synthesis and biological evaluation of benzo[d]thiazole with dimethylpyrazole derivatives>, Application of C7H6Cl2, the main research area is dimethylpyrazolyl benzothiazole preparation antitumor anticonvulsant SAR neurotoxicity; Benzothiazole; Dimethylpyrazol; MTT assay, GABAergic; Maximal Electroshock.

A series of new benzothiazole derivatives containing dimethylpyrazole I [R = H, n-pentyl, benzyl, etc.] were synthesized and evaluated for their anticonvulsant activity, neurotoxicity and cytotoxicity by using the maximal electroshock (MES), rotarod neurotoxicity (TOX) and MTT colorimetric assay. Among the compounds studied, four compounds I [R = Bu, n-pentyl, 2-fluorobenzyl, 2,6-dichlorobenzyl] showed better anticonvulsant than the others at 300 mg/kg and they also showed anticonvulsant activity at the dose of 100 mg/kg. All the synthetic compounds I showed lower neurotoxicity and little cytotoxicity, so that the compounds, which with better activities, also had higher protective index. In particular, the compound I [R = 2-fluorobenzyl] showed better activity with an ED50 value of 160.4 mg/kg and higher protective index (PI) values of 2.74 in the MES test than the standard drugs sodium valproate, which used as pos. controls in this study. After that the compound I [R = 2-fluorobenzyl] demonstrated antagonistic activity against seizures induced by pentylenetetrazol, which proved compound I [R = 2-fluorobenzyl] may be exert activity through effecting GABAergic neurotransmission.

Jeans, Rebekah J.; Chan, Antony P. Y.; Murrell, Ashton H.; Chouman, Heather A.; Rosair, Georgina M.; Welch, Alan J. published the artcile< Metalation of Bis(meta-carborane)>, Application In Synthesis of 67421-02-7, the main research area is bicarborane metalation preparation metallacarborane ruthenium cobalt sandwich complex; crystal structure ruthenium cobalt sandwich bicarborane arene cyclopentadienyl complex; mol structure ruthenium cobalt sandwich bicarborane arene cyclopentadienyl complex.

The first metallacarborane derivatives of 1,1′-bis(meta-carborane) I [vertex = BH; 2, M = Ru(p-cymene), Z = H; 3, M = Ru(p-cymene), Z = OEt; 4, M = Ru(C6Me6), Z = H; 5, M = Ru(C6Me6), Z = OEt; 6, M = CoCp, Z = H; 7, M = Co(C5Me5), Z = H], have been prepared by deboronation of one cage and subrogation of the {BH} fragment removed by an isolobal {Ru(arene)}, {CoCp} or {CoCp*} fragment. In the case of the Ru(arene) species, attack on the products 2 and 4 by EtO- resulted in derivatives 3 and 5, resp., in which an OEt group is attached to B6 of the metallacarborane cage. All products were characterised by multinuclear NMR spectroscopy and single-crystal X-ray diffraction. All are of the form the 2,1,7-MC2B9-1′,7′-C2B10, and even though the structural studies reveal clear evidence of steric crowding between the arene or Cp/Cp* ligand on the metal and the pendant carborane cage, no isomerization of the metallacarborane to either 2,1,8-MC2B9 or 2,1,12-MC2B9 occurs, even on heating to reflux in toluene.

The direct activation of cannabinoid receptors (CBRs) results in several beneficial effects; therefore several CBRs ligands have been synthesized and tested in vitro and in vivo. However, none of them reached an advanced phase of clin. development due mainly to side effects on the CNS. Medicinal chem. approaches are now engaged to develop allosteric modulators that might offer a novel therapeutic approach to achieve potential therapeutic benefits avoiding inherent side effects of orthosteric ligands. Here we identify the first ever synthesized pos. allosteric modulator (PAM) that targets CB2Rs. The evidence for this was obtained using [3H]CP55940 and [35S]GTPγS binding assays. This finding will be useful for the characterization of allosteric binding site(s) on CB2Rs which will be essential for the further development of CB2R allosteric modulators. Moreover, the new CB2R PAM displayed antinociceptive activity in vivo in an exptl. mouse model of neuropathic pain, raising the possibility that it might be a good candidate for clin. development.

Huang, Zaihui; Qi, Zheng; Ding, Xiaohu; Liu, Chunguang published the artcile< N-chlorosuccinimide enhancing the antimicrobial effect of benzalkonium chloride on biofilm Pseudomonas aeruginosa and its interaction mechanisms>, Application In Synthesis of 128-09-6, the main research area is chlorosuccinimide benzalkonium chloride antimicrobial biofilm Pseudomonas; Quaternary ammonium cationic surfactants; antimicrobial agents; cytotoxicity; ecotoxicology.

This study investigated the influence of N-chlorosuccinimide (NCS) pretreatment on the antimicrobial effect of benzalkonium chloride (BZC, representative of QACs) against biofilm bacteria and its mechanisms. Results show that 0.04 – 0.07 mmol/L NCS pretreatment significantly increased the antimicrobial efficacy of 0.03 mmol/L BZC on biofilm cells by 30% – 70%. The main mechanisms involved membrane permeability, oxidative damage, and metabolic disorder. More precisely, NCS pretreatment increased the permeability of bacteria and reduced the activity of the electron transport system (ETS) and dehydrogenase (DHA). At the same time, the oxidative damage of both endogenous and exogenous ROS and the disorder of the antioxidant enzymes (superoxide dismutase and catalase) further improved their combined antibacterial ability. Moreover, NCS pretreatment greatly reduced the resistance of biofilm Pseudomonas aeruginosa to BZC. The findings of the study provide a new method to effectively enhance the antimicrobial efficiency of quaternary ammonium cationic surfactants (e.g., BZC) and reduce bacterial resistance, as well as a scientific guidance for the development of new antimicrobial products.

A highly efficient aromatic chlorination of arenes such as 1-methyl-indazole, imidazo[1,2-a]pyrazine, phenylthiophene, anthracene, etc. that is catalyzed by DMSO with N-chlorosuccinimide as the chloro source is reported. The mild conditions, easy-availability and stability of the catalyst and reagents, as well as good functional-group tolerance, showed the approach to be a versatile protocol for the late-stage aromatic chlorination of complex natural products, e.g., papaverine, drugs, e.g., diclofenac and peptides, e.g., I. The multi-gram experiment and low-cost of N-chlorosuccinimide and DMSO show great potential for drug discovery and development in industrial applications.

Xu, Pin; Chen, Peng-Yu; Xu, Hai-Chao published the artcile< Scalable Photoelectrochemical Dehydrogenative Cross-Coupling of Heteroarenes with Aliphatic C-H Bonds>, Safety of 2,6-Dichloro-9-methyl-9H-purine, the main research area is heteroarene photoelectrochem dehydrogenative radical cross coupling light; alkylated heteroarene preparation; C−H functionalization; electrochemistry; heterocycles; photoelectrochemistry; radical reactions.

Heteroarenes are structural motifs found in many bioactive compounds and functional materials. Dehydrogenative cross-coupling of heteroarenes with aliphatic C-H bonds provides straightforward access to functionalized heteroarenes from readily available materials. Established methods employ stoichiometric chem. oxidants under conditions of heating or light irradiation By merging electrochem. and photochem., we have achieved efficient photoelectrochem. dehydrogenative cross-coupling of heteroarenes and C(sp3)-H donors through H2 evolution, without the addition of metal catalysts or chem. oxidants. Mechanistically, the C(sp3)-H donor is converted to a nucleophilic carbon radical through H-atom transfer with chlorine atom, which is produced by light irradiation of anodically generated Cl2 from Cl-. The carbon radical then undergoes radical substitution to the heteroarene to afford alkylated heteroarene products.

By combining “”N-chlorosuccinimide (NCS)”” as the safe chlorine source with “”Acr+-Mes”” as the photocatalyst, we successfully achieved benzylic C-H bond chlorination under visible light irradiation Furthermore, benzylic chlorides could be converted to benzylic ethers smoothly in a one-pot manner by adding sodium methoxide. This mild and scalable chlorination method worked effectively for diverse toluene derivatives, especially for electron-deficient substrates. Careful mechanistic studies supported that NCS provided a hydrogen abstractor “”N-centered succinimidyl radical,”” which was responsible for the cleavage of the benzylic C-H bond, relying on the reducing ability of Acr•-Mes.

Purely organic luminophores that exhibit room temperature phosphorescence (RTP) are receiving an ever-growing attention. The design of efficient RTP materials and the understanding of their emissive behavior, however, remain a challenging task. Herein, to gain further insights into metal-free RTP, we report the synthesis, characterization, and photophys. study of chloro-derivatives of [1,2-a:1′,2′-c:1”,2”-e][1,3,5]triazine or cyclic triimidazole (TT). Mono- (1Cl), di- (2Cl) and tri-chloro-TT (3Cl) derivatives are prepared by mild chlorination with N-chlorosuccinimide (NCS). The three compounds are characterized by aggregation-induced emission (AIE) comprising dual fluorescence and multiple phosphorescences, whose origin is disclosed by crystal structure anal. together with accurate DFT/TDDFT calculations Comparison with previously reported bromine and iodine TT derivatives reveals the new chlorinated compounds as the best performing halogenated AIE members of the family.
