In this research, authors synthesized the Fe₃O₄/CuO/ZnO@MWCNT magnetic nanocomposites using water extract of Petasites hybridus rhizome, and the high performance of synthesized catalyst was confirmed by using in the solvent-free multicomponent reactions of isatoic anhydride, N-methylimidazole, alkyl bromides, activated acetylenic compounds and 2-aminoacetonitrile at ambient temperature for the production of new cyanopyrroloazepine derivatives in high yields. This catalyst could be used several times in these reactions and have main role in the yield of product. The synthesized cyanopyrroloazepines have NH groups in their structure and for this reason have good antioxidant activity. Also, employing Gram-pos. and Gram-neg. bacteria in the disk diffusion procedure confirmed some cyanopyrroloazepines antimicrobial effect. The results showed that synthesized cyanopyrroloazepine prevented the bacterial growth. This used process for preparation of new cyanopyrroloazepine has some improvements such as low reaction time, product with high yields, simple separation of catalyst and products.

Yang, Zeyu;Ye, Wenjie;Xie, Youyu;Liu, Qinghai;Chen, Rong;Wang, Hualei;Wei, Dongzhi research published 《 Efficient Asymmetric Synthesis of Ethyl (S)-4-Chloro-3-hydroxybutyrate Using Alcohol Dehydrogenase SmADH31 with High Tolerance of Substrate and Product in a Monophasic Aqueous System》, the research content is summarized as follows. Bioredns. catalyzed by alc. dehydrogenases (ADHs) play an important role in the synthesis of chiral alcs. However, the synthesis of Et (S)-4-chloro-3-hydroxybutyrate [(S)-CHBE], an important drug intermediate, has significant challenges concerning high substrate or product inhibition toward ADHs, which complicates its production Herein, we evaluated a novel ADH, SmADH31, obtained from the Stenotrophomonas maltophilia genome, which can tolerate extremely high concentrations (6 M) of both substrate and product. The coexpression of SmADH31 and glucose dehydrogenase from Bacillus subtilis in Escherichia coli meant that as much as 660 g L^-1 (4.0 M) Et 4-chloroacetoacetate was completely converted into (S)-CHBE in a monophasic aqueous system with a >99.9% ee value and a high space-time yield (2664 g L^-1 d^-1). Mol. dynamics simulation shed light on the high activity and stereoselectivity of SmADH31. Moreover, five other optically pure chiral alcs. were synthesized at high concentrations (100-462 g L^-1) as a result of the broad substrate spectrum of SmADH31. All these compounds act as important drug intermediates, demonstrating the industrial potential of SmADH31-mediated bioredns.

Yao, Yongfang;Koshti, Rohit R.;Vyas, Akshay;Sangani, Chetan B.;Duan, Yongtao;Kumar Ameta, Rakesh;Tarpada, Umesh P.;Patel, H. N. research published 《 λ-shaped to T-shaped azo diester mesogens having methyl (-CH₃)/methoxy(-OCH₃) terminal substituents with trisubstituted benzene》, the research content is summarized as follows. A two homologous series of λ-shape to T-shape mesogenic azo diesters were synthesized and their thermotropic properties were studied by differential scanning calorimetry and a hot-stage polarizing optical microscope. The difference between these two series was in the structure of terminal substituents Me (-CH₃) for series I and methoxy (-OCH₃) for series II at one terminus. Structure variation from λ-shape to T-shape from lower members to higher members was discussed. In the series I, methoxy to n-pentyloxy derivatives were non-mesogenic. The n-hexyloxy derivative exhibited only monotropic nematic mesophase, n-heptyloxy to n-dodecyloxy derivatives exhibited monotropic smectic C mesophase and n-tetradecyloxy derivative exhibited enantiotropic SmA mesophase, whereas n-hexadecyloxy derivatives exhibited monotropic Smectic A mesophase. In series II, methoxy to n-hexyloxy derivatives were non-mesogenic, n-heptyloxy and n-octyloxy derivatives exhibited monotropic smectic C mesophase. Smectic A mesophase commences from the n-decyloxy derivative as a monotropic and persists up to the last member synthesized. The mesomorphic properties of the present series were compared with each other and with the structurally related mesogenic homologous series to evaluate the effect of Me (-CH₃)/methoxy (-OCH₃) substituents as well as variation in the shape of the mol. by varying the alkoxy chain length of the bulky lateral substituent on mesomorphism.

Ye, Zecheng;Chen, Jinzhu research published 《 Sulfonate-Grafted Metal-Organic Frameworks for Reductive Functionalization of CO₂ to Benzimidazoles and N-Formamides》, the research content is summarized as follows. Metal-organic frameworks (MOFs) with inner salt of 3-(pyridinylium)-1-propanesulfonate (PS) as the organic linkage were developed as catalysts (PS/MOFs) for reductive functionalization of carbon dioxide (CO₂) to benzimidazoles and N-formamides. The pendant -SO₃^– anion in the PS/MOFs acted as an organocatalytic active site for reductive cyclization of CO₂ with 1,2-phenylenediamine to afford 1H-benzo[d]imidazole. A linear correlation was observed between the catalytic performance (in terms of turnover frequencies) and the sp. surface area of PS/MOFs at a low conversion level of 1,2-phenylenediamine. The authors’ theor. study revealed significantly reduced energy barriers from 2.03 eV under catalyst-free conditions to 0.97 eV in the presence of the catalyst. The developed PS/MOFs can efficiently promote a broad range of benzimidazoles in 88-99% yields through reductive cyclization. Moreover, the PS/MOFs can readily catalyze N-formylation of various monoamines with CO₂ as the carbonyl source for quant. syntheses of N-formamides. The research thus highlights MOF-based catalysts for organocatalytic transformation of CO₂ into high value-added chems.

Yoshinaga, Hidefumi;Nishida, Tomoaki;Sasaki, Izumi;Kato, Taro;Oki, Hitomi;Yabuuchi, Kazuki;Toyoda, Tomohiro research published 《 Discovery of DSP-1053, a novel benzylpiperidine derivative with potent serotonin transporter inhibitory activity and partial 5-HT_1A receptor agonistic activity》, the research content is summarized as follows. The authors have previously shown that SMP-304, a serotonin uptake inhibitor with weak 5-HT_1A partial agonistic activity, may act under high serotonin levels as a 5-HT_1A antagonist that improves the onset of paroxetine in the rat swimming test. However, SMP-304 is mostly metabolized by CYP2D6, indicating limited efficacy among individuals and increased side effects. To reduce CYP2D6 metabolic contribution and enhance SERT/5-HT_1A binding affinity, the authors carried out a series of substitutions at the bromine atom in the left part of the benzene ring of SMP-304 and replaced the right part of SMP-304 with a chroman-4-one. This optimization work led to the identification of the antidepressant candidate DSP-1053 (6-(2-(4-[4-Bromo-3-(2-methoxyethoxy)benzyl]piperidin-1-yl)ethyl)-2,3-dihydro-4H-chromen-4-one) as a potent SERT inhibitor with partial 5-HT_1A receptor agonistic activity. DSP-1053 showed low CYP2D6 metabolic contribution and a robust increase in serotonin levels in the rat frontal cortex.

Research on ionic liquids is constantly providing information on their new and more advanced applications. Undoubtedly, the use of latent curing agents for epoxy resins is one of the most interesting applications of this group of compounds In this work, a detailed description of the synthesis and physicochem. studies of DABCO-based (1,4-diazabicylo[2.2.2]octane) ionic liquids is presented. Their most valuable feature is that they can be latent curing agents for polymerization of epoxy resins, which in turn can be used, when combined with fibers, as composites with special, new properties. The research includes detailed discussion of synthesis of new DABCO-ILs, focusing on obtaining pure compounds and expanding current knowledge on the subject. Thermal (DSC) and chromatog. (IC) properties have been discussed for all presented salts. Furthermore, ionic liquids with dicyanamide and triflate anion have demonstrated the ability to initiate polymerization of epoxy resins. Subsequently, all mixtures were cured into cubical shape and were subjected to the Shore hardness test (SHT). The main advantages of the obtained ILs are (i) the ability to store ionic liquids/epoxy resin mixture for prolonged periods of time without deterioration of curing properties and (ii) a significantly lower quantity of ionic liquids used in the process of curing epoxy resins.
