Preparation and characterization of novel thin film composite forward osmosis membrane with halloysite nanotube interlayer was written by Cheng, Bohao;Wang, Yifan;Wu, Xiaowen;Fang, Minghao;Min, Xin;Huang, Zhaohui;Liu, Yan’gai;Mi, Ruiyu. And the article was included in Polymer in 2022.Synthetic Route of C9H3Cl3O3 This article mentions the following:

In this study, the electrospun polyacrylonitrile (ePAN) fiber mats were used as support layer and natural mineral-halloysite nanotubes (HNTs) was used to construct the interlayer. Polydopamine modification was utilized to enhance the hydrophilicity of ePAN substrates and dispersibility of HNTs. The mHNTs interlayer effectively minified the surface pore size of substrates providing a better interface for interfacial polymerization forming an integrated and thin PA selective layers. Compared to the unmodified membranes, the water flux of the optimized membrane with mHNTs interlayer about 61.60% and 79.70% higher and the reverse salt flux of which was 38.95% and 45.08% lower in AL-FS mode and AL-DS mode resp. These results suggested that introducing halloysite nanotube interlayer is an effective, and low-cost way to fabricate high-performance FO membrane. In the experiment, the researchers used many compounds, for example, Trimesoylchloride (cas: 4422-95-1Synthetic Route of C9H3Cl3O3).

Effective single and contest carcinogenic dyes adsorption onto A-zeolite/bacterial cellulose composite membrane: Adsorption isotherms, kinetics, and thermodynamics was written by Ibrahim, Shaimaa M.;Ghanem, Ahmed F.;Sheir, Donia H.;Badawy, Abdelrahman A.. And the article was included in Journal of Environmental Chemical Engineering in 2022.Safety of 3,7-Bis(dimethylamino)phenothiazin-5-ium chloride This article mentions the following:

This study reports loading of A-zeolite particles on the bacterial cellulose membrane for single and binary carcinogenic dye uptake from the aqueous solution The bio based membrane was obtained using Gluconobacter Oxydans NRRL 759 in liquid culture medium. Meanwhile, the incorporation of zeolite particles within the bacterial cellulose matrix and on its surface was implemented via in-situ synthesis. The crystallite structure and the morphol. of obtained composite membrane were characterized with X-ray diffraction (XRD) and SEM (SEM) hyphenated with energy dispersive X-ray (EDX). The surface characteristics were intensively investigated by N2 adsorption/desorption isotherm, SBET, pore size distribution, and zeta potential. The results indicate that the treatment of bacterial cellulose with zeolite particles reflected two folds in surface area and three folds in the point of zero charge (pHzpc 6.7) compared with un-modified one. The produced composite membrane was also examined against removal of sole cationic methylene blue “MB”, and anionic Congo-Red “CR” or in binary solutions included “MB” with Malachite green “MG”or “CR”with different percentages through batch adsorption technique. Different parameters affecting the adsorption process, such as dye concentration, adsorbent type, contact time, temperature, and pH, were optimized. The highest removal was recorded at optimum conditions for sole “MB” dye (99.2%),”CR” dye (81%), binary mixed “2MB/1CR” (96% after 15 min, 91% after 12 h, resp.), and “2MB/1MG”(98.6% after 30 min). Moreover, linear and nonlinear adsorption isotherm models confirmed that MB adsorption and CR obeys Freundlich isotherm model. Also, the kinetic studies revealed that the dyes′ adsorption on the composite membrane could be clarified using linear and nonlinear forms of pseudo-first order, pseudo-second order, and intra-particle diffusion models. Thermodn. findings emphasized the endothermic and spontaneous adsorption process as the adsorbent/ adsorbate phys. interaction decreased the entropy. Eventually, the recyclability test revealed that the composite matrix exhibits excellent removal efficiency up to 5 recycles. The primary adsorption mechanism was proposed and confirmed with Fourier transform IR (FTIR). Finally, the unprecedented composite membrane can be considered as an economically distinguished adsorbent for the removal of not only sol dyes but also mixtures of anionic and cationic dyes. In the experiment, the researchers used many compounds, for example, 3,7-Bis(dimethylamino)phenothiazin-5-ium chloride (cas: 61-73-4Safety of 3,7-Bis(dimethylamino)phenothiazin-5-ium chloride).

A small molecule inhibitor selective for a variant ATP-binding site of the chaperonin GroEL was written by Chapman, Eli;Farr, George W.;Furtak, Krystyna;Horwich, Arthur L.. And the article was included in Bioorganic & Medicinal Chemistry Letters in 2009.Formula: C9H9ClO2 This article mentions the following:

The chaperonin GroEL is a megadalton-sized mol. machine that plays an essential role in the bacterial cell assisting protein folding to the native state through actions requiring ATP binding and hydrolysis. A combination of medicinal chem. and genetics has been employed to generate an orthogonal pair, a small mol. that selectively inhibits ATPase activity of a GroEL ATP-binding pocket variant. An initial screen of kinase-directed inhibitors identified an active pyrazolo-pyrimidine scaffold that was iteratively modified and screened against a collective of GroEL nucleotide pocket variants to identify a cyclopentyl carboxamide derivative, EC3016, that specifically inhibits ATPase activity and protein folding by the GroEL mutant, I493C, involving a side chain positioned near the base of ATP. This orthogonal pair will enable in vitro studies of the action of ATP in triggering activation of GroEL-mediated protein folding and might enable further studies of GroEL action in vivo. The approach originated for studying kinases by Shokat and his colleagues may thus also be used to study large macromol. machines. In the experiment, the researchers used many compounds, for example, 2-(3-Methoxyphenyl)acetyl chloride (cas: 6834-42-0Formula: C9H9ClO2).

Novel bis-(arylsulfonamide) hydroxamate-based selective MMP inhibitors was written by Subramaniam, Rajesh;Haldar, Manas K.;Tobwala, Shakila;Ganguly, Bratati;Srivastava, D. K.;Mallik, Sanku. And the article was included in Bioorganic & Medicinal Chemistry Letters in 2008.Quality Control of 2,4-Dimethoxybenzene-1-sulfonyl chloride This article mentions the following:

A series of bis(arylsulfonamide) hydroxamate inhibitors were synthesized. These compounds exhibit good potency against MMP-7 and MMP-9 depending on the nature, steric bulk, and substitution pattern of the substituents in the benzene ring. In general, the preliminary structure-activity relationships (SAR) suggest that among the 2,3-diaminopropanoic acid hydroxamates (i) electron-rich benzene rings of the sulfonamides may produce better inhibitors than electron-poor analogs. However, potential H-bond acceptors can reverse the trend depending on the isoenzyme; (ii) isoenzyme selectivity between MMP-7 and -9 can be conferred through steric bulk and substitution pattern of the substituents in the benzene ring, and (iii) the MMP-10 inhibition pattern of the compounds paralleled that for MMP-9.
