By imitating the scaffold of lithocholic acid (LCA), a natural steroidal compound displaying Protein Tyrosine Phosphatase 1B (PTP1B) inhibitory activity, a series of stilbene derivatives containing phenyl-substituted isoxazoles were designed and synthesized. The structures of the title compounds were confirmed by 1H-NMR, 13C-NMR and HRMS. Activities of the title compounds were evaluated on PTP1B and the homologous enzyme TCPTP by using a colorimetric assay. Most of the target compounds had good activities against PTP1B. Among them, compound 29 (IC50 = 0.91 ± 0.33 μM), characterized by a 5-(2,3-dichlorophenyl) isoxazole moiety, exhibited an activity about 14-fold higher than the lead compound LCA and a 4.2-fold selectivity over TCPTP. Compound 29 was identified as a competitive inhibitor of PTP1B with a Ki value of 0.78 μM in enzyme kinetic studies. In the experiment, the researchers used Methyl 3-(bromomethyl)benzoate(cas: 1129-28-8Recommanded Product: Methyl 3-(bromomethyl)benzoate)

And the article was published in Small in 2019. Formula: C8H15BrO2 The author mentioned the following in the article:

Gold nanoparticles (AuNPs) covered with mixtures of immiscible ligands present potentially anisotropic surfaces that can modulate their interactions at complex nano-bio interfaces. Mixed, self-assembled, monolayer (SAM)-protected AuNPs, prepared with incompatible hydrocarbon and fluorocarbon amphiphilic ligands, are used here to probe the mol. basis of surface phase separation and disclose the role of fluorinated ligands on the interaction with lipid model membranes and cells, by integrating in silico and exptl. approaches. These results indicate that the presence of fluorinated amphiphilic ligands enhances the membrane binding ability and cellular uptake of gold nanoparticles with respect to those coated only with hydrogenated amphiphilic ligands. For mixed monolayers, computational results suggest that ligand phase separation occurs on the gold surface, and the resulting anisotropy affects the number of contacts and adhesion energies with a membrane bilayer. This reflects in a diverse membrane interaction for NPs with different surface morphologies, as determined by surface plasmon resonance, as well as differential effects on cells, as observed by flow cytometry and confocal microscopy. Overall, limited changes in monolayer features can significantly affect NP surface interfacial properties, which, in turn, affect the interaction of SAM-AuNPs with cellular membranes and subsequent effects on cells. The experimental process involved the reaction of 8-Bromooctanoic acid(cas: 17696-11-6Formula: C8H15BrO2)

In 2017,Lu, Zhiyong; Xing, Yue; Du, Liting; He, Haiyan; Zhang, Jianfeng; Hang, Cheng published 《Isostructural functionalization by -OH and -NH2: different contributions to CO2 adsorption》.RSC Advances published the findings.Formula: C6H5Br2N The information in the text is summarized as follows:

Two isostructural mfj-type metal-organic frameworks, [Cu2(ABDPB)(H2O)]n (HHU-3, HHU for Hohai University; H4ABDPB for 5-amino-1,3-bis(3,5-dicarboxylphenyl)-benzene) and [Cu2(OBDPB)(H2O)]n (HHU-4; H4OBDPB for 5-hydroxyl-1,3-bis(3,5-dicarboxylphenyl)-benzene) were successfully synthesized by V-shaped tetracarboxylic ligand with amino and hydroxyl groups, resp. Compared with the prototypical MOF, PCN-306, both MOFs exhibit obviouse decreases in BET surface area and pore volume, with the values of 2354 m2 g-1 and 0.920 cm3 g-1 for HHU-3, and 2353 m2 g-1 and 0.954 cm3 g-1 for HHU-4. Although both functional groups are believed to be effective in strengthen CO2 interactions with the framework, in this type of MOF, amino group works better due to its basic nature. Meanwhile, the decoration of amino groups grafted HHU-3 high CO2 adsorption capacity (25.6 wt% at 1 bar and 273 K) and high CO2 selectivity (SCO2/N2 = 129).3,5-Dibromoaniline(cas: 626-40-4Formula: C6H5Br2N) was used in this study.

《Trivalent ion mediated abnormal growth of all-inorganic perovskite nanocrystals and their divergent emission properties》 was written by Dong, Xunyi; Acheampong Tsiwah, Emmanuel; Li, Tan; Hu, Junjie; Li, Zixiong; Ding, Yanxi; Deng, Zhao; Chen, Wenhui; Xu, Like; Gao, Peng; Zhao, Xiujian; Xie, Yi. Related Products of 13465-09-3This research focused ontrivalent ion dopped inorganic perovskite nanocrystal photoluminescence optical absorption. The article conveys some information:

In this work, a new trivalent ion-mediated one-pot synthetic protocol is reported to create two well-defined optical absorbance and photoluminescence (PL) emissions in all-inorganic halide perovskite nanocrystals (NCs). The foreign M3+ cations (M = Bi, Al, In), typically from BiBr3, BiFeO3, BiCl3, AlBr3 or InBr3, function as capping ligands for generating a growth-constrained thinner nanoplatelet (NPL) population displaying the quantum confinement effect. The formation mechanism of the growth-constrained NPLs is proposed based on d. functional theory (DFT) on the different slab energy of the representative NPLs achieved in the presence of Bi3+ ions and the d. of states (DOS) of the supposed bulk perovskites. Notably, the formation of two groups of NCs with different sizes allows for the generation of dual optical absorbance and PL emissions. The influence of the M : Pb molar ratios on the precursors is systematically elucidated, from which the relative intensity and position of each PL emission can be fine-tuned. By virtue of the representative NPLs with well-defined green and blue emissions, the M3+-assisted synthetic protocol provides a facile and cost-effective route for producing unique NCs and nanostructures for optoelectronic device applications.
