Titrimetric determination of iodine-bromine numbers of some edible oils using three N-chloroimides was written by Jayasree, Narayanan;Indrasenan, Parameswaran. And the article was included in Journal – Association of Official Analytical Chemists in 1987.Category: chlorides-buliding-blocks This article mentions the following:

Three simple titrimetric methods were developed to determine I-Br numbers of some edible oils, such as coconut, gingelly, peanut, mustard, olive, palm olein, and sunflower, by using 3 N-chloroimides. The chloroimides are N-chlorophthalimide, N-chlorosuccinimide, and N-chlorosaccharin, all of which have recently been developed as potential oxidimetric titrants for use in aqueous HOAc medium. The proposed excess back-titration methods have advantages over existing methods in terms of ease of extraction into aqueous HOAc layer, shorter reaction time of the N-chlorosaccharin method, and stability of N-chloroimides in solid state. In the experiment, the researchers used many compounds, for example, 2-Chlorobenzo[d]isothiazol-3(2H)-one 1,1-dioxide (cas: 14070-51-0Category: chlorides-buliding-blocks).

2-Chlorobenzo[d]isothiazol-3(2H)-one 1,1-dioxide (cas: 14070-51-0) belongs to organic chlorides.

K.;Ighalo, Joshua O.. And the article was included in Sustainable Environment Research in 2022.HPLC of Formula: 61-73-4 This article mentions the following:

Rhizome extract of Bergenia ciliata was used as a bio-functional reducing material for the green synthesis of copper oxide nanoparticles (CuO NPs). CuO NPs were characterized using UV-visible spectroscopy, Fourier transforms IR spectroscopy, X-ray diffraction (XRD), dynamic light scattering, SEM (SEM) and energy-dispersive X-ray anal. (EDX). XRD anal. revealed the monoclinic phase of synthesized CuO NPs with an average particle size of 20 nm. Spherical shaped nanoscale CuO particles were observed by EDX and SEM confirming the Cu and O presence in the synthesized NPs. CuO NPs showed antibacterial effects against Bacillus subtilis, Staphylococcus aureus, Escherichia coli, Salmonella typhi. The antioxidant effect was measured and IC50 values for 2,2′-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid (ABTS)), 2,2-diphenyl-1-picrylhydrazyl and Ferric reducing antioxidant power assays were found to be 91.2, 72.4 and 109μg mL- 1 resp.

Robust polyamide-PTFE hollow fibre membranes for harsh organic solvent nanofiltration was written by Francis, Verona Nithya;Chong, Jeng Yi;Yang, Guoying;Che, Lei;Wang, Rong. And the article was included in Chemical Engineering Journal (Amsterdam, Netherlands) in 2023.Category: chlorides-buliding-blocks This article mentions the following:

Polymeric membranes have been extensively studied for organic solvent nanofiltration (OSN) but many fail to show sufficient chem. resistance in strong solvents like DMF (DMF) and DMSO (DMSO). This study focuses on harnessing the outstanding chem. resistance of polytetrafluoroethylene (PTFE), to develop polyamide-PTFE thin film composite (TFC) membranes that are resistant to such aprotic solvents. A defect-free polyamide thin film layer was successfully synthesized on the microfiltration PTFE hollow fiber substrates, overcoming challenges such as large and uneven pore size, and hydrophobicity of the PTFE substrates. A simple polydopamine (PDA) coating was carried out to improve the substrate’s hydrophilicity prior to the polyamide synthesis via interfacial polymerization (IP). Polyethyleneimine (PEI) and trimesoyl chloride (TMC) were used as the monomers and a two-time IP method was employed to obtain a defect-free polyamide coating. The synthesized membranes showed high acetonitrile (ACN) and DMF permeabilities of 7.94 and 3.70 lm^-2h^-1bar^-1, resp., with acid fuchsin (585 Da) rejections of > 90%. The mol. weight cut-off (MWCO) of the membranes could be further reduced to ∼300 Da by the addition of piperazine (PIP) monomers. The membranes also showed excellent stability and performance in a 72-h OSN test performed in DMF indicating their great potential in effective mol. separation in harsh solvents. This study demonstrates how a simple modification and coating technique can transform com. available microfiltration PTFE hollow fibers into durable and high value OSN membranes. In the experiment, the researchers used many compounds, for example, Trimesoylchloride (cas: 4422-95-1Category: chlorides-buliding-blocks).

Trimesoylchloride (cas: 4422-95-1) belongs to organic chlorides.

Extending from a study we recently published examining the anti-trypanosomal effects of a series of GroEL/ES inhibitors based on a pseudo-sym. bis-sulfonamido-2-phenylbenzoxazole scaffold, here, we report the antibiotic effects of asym. analogs of this scaffold against a panel of bacteria known as the ESKAPE pathogens (Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter species). While GroEL/ES inhibitors were largely ineffective against K. pneumoniae, A. baumannii, P. aeruginosa, and E. cloacae (Gram-neg. bacteria), many analogs were potent inhibitors of E. faecium and S. aureus proliferation (Gram-pos. bacteria – EC₅₀ values of the most potent analogs were in the 1-2 μM range). Furthermore, even though some compounds inhibit human HSP60/10 biochem. functions in vitro (IC₅₀ values in the 1-10 μM range), many of these exhibited moderate to low cytotoxicity to human liver and kidney cells (CC₅₀ values >20 μM). In the experiment, the researchers used many compounds, for example, 3-(Trifluoromethyl)benzene-1-sulfonyl chloride (cas: 777-44-6Name: 3-(Trifluoromethyl)benzene-1-sulfonyl chloride).

Finding of the low molecular weight inhibitors of resuscitation promoting factor enzymatic and resuscitation activity was written by Demina, Galina R.;Makarov, Vadim A.;Nikitushkin, Vadim D.;Ryabova, Olga B.;Vostroknutova, Galina N.;Salina, Elena G.;Shleeva, Margarita O.;Goncharenko, Anna V.;Kaprelyants, Arseny S.. And the article was included in PLoS One in 2009.Recommanded Product: 16588-16-2 This article mentions the following:

Background: Resuscitation promoting factors (RPF) are secreted proteins involved in reactivation of dormant actinobacteria, including Mycobacterium tuberculosis. They have been considered as prospective targets for the development of new anti-tuberculosis drugs preventing reactivation of dormant tubercle bacilli, generally associated with latent tuberculosis. However, no inhibitors of Rpf activity have been reported so far. The goal of this study was to find low mol. weight compounds inhibiting the enzymic and biol. activities of Rpfs. Methodol./Principal Findings: Here the authors describe a novel class of 2-nitrophenylthiocyanates (NPT) compounds that inhibit muralytic activity of Rpfs with IC₅₀ 1-7 μg/mL. Fluorescence studies revealed interaction of active NPTs with the internal regions of the Rpf mol. Candidate inhibitors of Rpf enzymic activity showed a bacteriostatic effect on growth of Micrococcus luteus (in which Rpf is essential for growth protein) at concentrations close to IC₅₀. The candidate compounds suppressed resuscitation of dormant (“non-culturable”) cells of M. smegmatis at 1 μg/mL or delayed resuscitation of dormant M. tuberculosis obtained in laboratory conditions at 10 μg/mL. However, they did not inhibit growth of active mycobacteria under these concentrations Conclusions/Significance: NPT are the first example of low mol. weight compounds that inhibit the enzymic and biol. activities of Rpf proteins.

Effect of meta-substituents on aromatic nucleophilic substitution was written by Bevan, C. W. L.;Hirst, J.;Una, S. J.. And the article was included in Chemistry & Industry (London, United Kingdom) in 1966.Recommanded Product: 4815-64-9 This article mentions the following:

Displacement of F in 3,5-R(O₂N)C₆H₃F by OMe ions in MeOH varied by a factor of 10⁴ depending on the group R. The rate decreased as A varied in the order NO₂ > SO₂Me > CF₃ > Br > Cl > I > F > Ac > H > OMe > Me > CMe₃ > CO₂^– > NH₂. For PhF (no other substituent on the ring), the rate was 10^-4 which was the slowest of the meta-nitro-substituted series. All reactions were run at 100°. Despite an overall difference of 10⁸ in rates, the log B factor in the Arrhenius equation k = Be^-Ε/RT remained constant at approx. 12.5. The vast difference in rates was attributed to the changes in the activation energy. The reaction series was sensitive to electronic effects. Somewhat abnormal results, obtained where R was NH₂ or OMe, were attributed to 2nd-order effects in reactions especially sensitive to the charge d. on the C atoms ortho to that bonded to F. In the experiment, the researchers used many compounds, for example, 1-Chloro-3-fluoro-5-nitrobenzene (cas: 4815-64-9Recommanded Product: 4815-64-9).
