Related Products of 14660-52-7 And the article was included in Asian Journal of Chemistry in 2020. The article conveys some information:

A series of sixteen new ionic liquids (ILs) bearing imidazolium moiety I (R = 2-chlorobenzyl, 3-cyanopropyl, 4-acetoxybutyl, etc.; X = Cl, Br) were designed and synthesized under sustainable and green conditions which were confirmed by anal. and spectral techniques using 1H- & 13C-NMR, FT-IR, mass and elemental anal. A panel of clin. isolated strains was used for in vitro inhibitory antimicrobial activities screening of synthesized ionic liquids I. The results of antimicrobial assay showed that some of synthesized ionic liquids I showed moderate to good activity. Among these ILs, ionic liquids (bearing alkyl chain with a Ph group) I [R = (2-chlorophenyl)methyl, X = Cl; R = 2-phenoxyethyl, X = Br; R = 3-phenoxypropyl, X = Br] significantly inhibited cell growth of strains. In this regard, these ionic liquids I considered as promising antibacterial agents when compared with standard antibiotics. By encouraging in vitro antimicrobial screening, in silico ADMET evaluation has been performed and found excellent pharmacokinetic, bioavailability and toxicity profiles. Synthesized ionic liquids have found to be safe and non-toxic according to calculated in vivo computed LD50 values (2.49-2.80 mg/kg) for rat acute toxicity.

《Universal Antibacterial Surfaces Fabricated from Quaternary Ammonium Salt-Based PNIPAM Microgels》 was published in ACS Applied Materials & Interfaces in 2020. These research results belong to Zhao, Ziqing; Ma, Xiaoliang; Chen, Rui; Xue, Hui; Lei, Jiehua; Du, Hui; Zhang, Zexin; Chen, Hong. Name: 1,6-Dibromohexane The article mentions the following:

Because of the excellent film-forming ability of poly(N-isopropylacrylamide) (PNIPAM) microgel and high-efficient bactericidal property of quaternary ammonium salt (QAS), QAS-based PNIPAM (QAS-PNIPAM) microgels are synthesized and employed to modify the surface of a range of commonly used materials including metal, plastic, and elastomer. Bacterial culture is carried out on such QAS-PNIPAM microgel-modified surfaces to examine the viability of the attached bacteria. It is found that the bactericidal efficiency is nearly 100% on the modified surfaces of all the studied materials. We attribute the high-efficient bactericidal performance of QAS-PNIPAM microgel film to the QAS component rather than the topog. of the microgel film itself. In addition, the microgel film is robust and shows great integrity even after culture of the bacteria and repeated rinses, and the cell experiment demonstrates that this microgel film is cyto-compatible. Therefore, such a simple, versatile method of preparing antibacterial films paves the way for future bactericidal applications. In the experimental materials used by the author, we found 1,6-Dibromohexane(cas: 629-03-8Name: 1,6-Dibromohexane)

Formula: C6H5Br2NIn 2021 ,《Design, synthesis and biological evaluation of pyrazole-aromatic containing carboxamides as potent SDH inhibitors》 appeared in European Journal of Medicinal Chemistry. The author of the article were Yu, Bin; Zhao, Bin; Hao, Zesheng; Chen, Lei; Cao, Lixin; Guo, Xiaofeng; Zhang, Nailou; Yang, Dongyan; Tang, Liangfu; Fan, Zhijin. The article conveys some information:

To continue studies on discovery of new potent antifungal leads, 43 novel pyrazole-aromatic containing carboxamides were rationally designed and synthesized. Bioassays indicated that most target compounds displayed good in vitro antifungal activities against Botrytis cinerea, Rhizoctonia cerealis and Sclerotinia sclerotiorum and in vivo antifungal activity against R. solani. Compound I exhibited the most significant in vitro activity against R. cerealis (EC50 = 0.93μg/mL) with about 2-fold more potent than a previously reported lead compound N-(3-bromophenyl)-2-[3-(difluoromethyl)-1-methyl-1H-pyrazol-4-yl]-4-thiazolecarboxamide (EC50 = 2.01μg/mL), and about 11-fold more potent than the pos. control/com. succinate dehydrogenase inhibitor thifluzamide (EC50 = 23.09μg/mL). Structure-activity relationship anal. and mol. docking simulations indicated that the presence of difluoromethyl pyrazole-(m-benzene)carboxamide scaffold obviously increased the antifungal activity. The further enzymic bioassay showed that both thifluzamide and compound I displayed excellent SDH inhibitory effects, and fluorescence quenching anal. suggested that they may share the same target SDH. The results came from multiple reactions, including the reaction of 3,5-Dibromoaniline(cas: 626-40-4Formula: C6H5Br2N)

3,5-Dibromoaniline(cas: 626-40-4) belongs to anime. Amines have a free lone pair with which they can coordinate to metal centers. Amine–metal bonds are weaker because amines are incapable of backbonding, but they are still important for sensing applications.While stronger than hydrogen bonds, amine–metal bonds are still weaker than both covalent and ionic bonds.Formula: C6H5Br2N

Recommanded Product: 14660-52-7In 2019 ,《Synthesis, biological evaluation, and molecular docking study of novel allyl-retrochalcones as a new class of protein tyrosine phosphatase 1B inhibitors》 appeared in Bioorganic & Medicinal Chemistry. The author of the article were Zhao, Yunjie; Cao, Yongkai; Chen, Huizhen; Zhuang, Fei; Wu, Chao; Yoon, Goo; Zhu, Weiwei; Su, Ying; Zheng, Suqing; Liu, Zhiguo; Cheon, Seung Hoon. The article conveys some information:

We describe herein the design, synthesis, and biol. evaluation of a series of novel protein tyrosine phosphatase 1B (PTP1B) inhibitor retrochalcones having an allyl chain at the C-5 position of their B ring. Biol. screening results showed that the majority of these compounds exhibited an inhibitory activity against PTP1B. Thus, preliminary structure-activity relationship (SAR) and quant. SAR analyses were conducted. Among the compounds, 23 was the most potent inhibitor, exhibiting the highest in vitro inhibitory activity against PTP1B with an IC50 of 0.57 μM. Moreover, it displayed a significant hepatoprotective property via activation of the IR pathway in type 2 diabetic db/db mice. In addition, the results of our docking study showed that 23, as a specific inhibitor of PTP1B, effectively transformed the WPD loop from “”close”” to “”open”” in the active site. These results may reveal suitable compounds for the development of PTP1B inhibitors. The results came from multiple reactions, including the reaction of Ethyl 5-bromovalerate(cas: 14660-52-7Recommanded Product: 14660-52-7)
