Carbonic anhydrase inhibitors. Identification of selective inhibitors of the human mitochondrial isozymes VA and VB over the cytosolic isozymes I and II from a natural product-based phenolic library was written by Davis, Rohan A.;Innocenti, Alessio;Poulsen, Sally-Ann;Supuran, Claudiu T.. And the article was included in Bioorganic & Medicinal Chemistry in 2010.Formula: C9H9ClO3 This article mentions the following:

We have investigated the enzyme inhibition characteristics of a natural product (NP)-based phenolic library against a panel of human carbonic anhydrases (hCAs, EC 4.2.1.1) which included hCAs I and II (cytosolic) and hCA VA/VB (mitochondrial isoforms). Most of these compounds were weak, micromolar inhibitors of the two cytosolic hCAs (K _Is >10 μM) but showed good hCA VA/VB inhibitory activity with inhibition constants in the range of 70-125 nM. The selectivity ratios for inhibiting the mitochondrial over the cytosolic isoforms for these phenol derivatives were in the range of 120-3800, making them the most isoform-selective compounds for inhibiting hCA VA/VB known to date. The CA VA/VB enzymes are involved in biosynthetic processes such as gluconeogenesis, lipogenesis and ureagenesis, and no pharmacol. inhibitors with good selectivity are currently available. Thus the NP inhibitors identified during these studies are excellent leads for obtaining even more effective compounds that selectively target mitochondrial hCAs, and also have the potential to be used as tools for understanding the physiol. processes that are regulated by the two mitochondrial CA isoforms. In the experiment, the researchers used many compounds, for example, Methyl 3-chloro-4-hydroxyphenylacetate (cas: 57017-95-5Formula: C9H9ClO3).

Methyl 3-chloro-4-hydroxyphenylacetate (cas: 57017-95-5) belongs to organic chlorides. Organic chlorides are compounds containing a carbon-chlorine bond, which are widely used in the oil field as a wax dissolver. Alkyl chlorides are versatile building blocks in organic chemistry. While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available.Formula: C9H9ClO3

Hierarchical Structure with Highly Ordered Macroporous-Mesoporous Metal-Organic Frameworks as Dual Function for CO₂ Fixation was written by Li, Zhenxing;Xing, Xiaofei;Meng, Dong;Wang, Zhengxu;Xue, Jingjing;Wang, Rui;Chu, Junmei;Li, Mingming;Yang, Yang. And the article was included in iScience in 2019.Quality Control of 1-(Chloromethyl)-3-methylbenzene This article mentions the following:

As a major greenhouse gas, the continuous increase of carbon dioxide (CO₂) in the atm. has caused serious environmental problems, although CO₂ is also an abundant, inexpensive, and nontoxic carbon source. Here, we use metal-organic framework (MOF) with highly ordered hierarchical structure as adsorbent and catalyst for chem. fixation of CO₂ at atm. pressure, and the CO₂ can be converted to the formate in excellent yields. Meanwhile, we have successfully integrated highly ordered macroporous and mesoporous structures into MOFs, and the macro-, meso-, and microporous structures have all been presented in one framework. Based on the unique hierarchical pores, high surface area (592 m²/g), and high CO₂ adsorption capacity (49.51 cm³/g), the ordered macroporous-mesoporous MOFs possess high activity for chem. fixation of CO₂ (yield of 77%). These results provide a promising route of chem. CO₂ fixation through MOF materials.

Exposure to environmental phenols and parabens, and relation to body mass index, eczema and respiratory outcomes in the Norwegian RHINESSA study was written by Vindenes, Hilde Kristin;Svanes, Cecilie;Lygre, Stein Haakon Laastad;Real, Francisco Gomez;Ringel-Kulka, Tamar;Bertelsen, Randi Jacobsen. And the article was included in Environmental Health (London, United Kingdom) in 2021.Category: chlorides-buliding-blocks This article mentions the following:

Many phenols and parabens are applied in cosmetics, pharmaceuticals and food, to prevent growth of bacteria and fungi. Whether these chems. affect inflammatory diseases like allergies and overweight is largely unexplored. We aimed to assess the associations of use of personal care products with urine biomarkers levels of phenols and paraben exposure, and whether urine levels (reflecting body burden of this chem. exposures) are associated with eczema, rhinitis, asthma, specific IgE and body mass index. Demographics, clin. variables, and self-report of personal care products use along with urine samples were collected concurrently from 496 adults (48% females, median age: 28 years) and 90 adolescents (10-17 years of age) from the RHINESSA study in Bergen, Norway. Urine biomarkers of triclosan (TCS), triclocarban (TCC), parabens and benzophenone-3, bisphenols and dichlorophenols (DCP) were quantified by mass spectrometry. Detection of the urine biomarkers varied according to chem. type and demographics. TCC was detected in 5% of adults and in 45% of adolescents, while Pr (PPB) and Me (MPB) parabens were detected in 95% of adults and in 94% (PPB) and 99% (MPB) of adolescents. Women had higher median urine concentrations of phenolic chems. and reported a higher frequency of use of personal care products than men. Urine concentration of MPB increased in a dose-dependent manner with increased frequency of use of several cosmetic products. Overall, urinary biomarker levels of parabens were lower in those with current eczema. The biomarker concentrations of bisphenol S was higher in participants with pos. specific IgE and females with current asthma, but did not differ by eczema or rhinitis status. MPB, ethylparaben (EPB), 2,4-DCP and TCS were inversely related to BMI in adults; interaction by gender were not significant. Reported frequency of use of personal care products correlated very well with urine biomarker levels of paraben and phenols. Several chems. were inversley related to BMI, and lower levels of parabens was observed for participants with current eczema. There is a need for further studies of health effects of chems. from personal care products, in particular in longitudinally designed studies. In the experiment, the researchers used many compounds, for example, 1-(4-Chlorophenyl)-3-(3,4-dichlorophenyl)urea (cas: 101-20-2Category: chlorides-buliding-blocks).

1-(4-Chlorophenyl)-3-(3,4-dichlorophenyl)urea (cas: 101-20-2) belongs to organic chlorides. Organic chlorides can cause corrosion in pipelines, valves and condensers, and cause catalyst poisoning. The hydrocarbon processing industry (HPI) and others are affected by damage caused by these substances. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light.

High-Performance PA Nanofiltration Membrane with Coral-Reef-Like Morphology atop Polydopamine Decorated EVOH Nanofiber Scaffold was written by Ma, Siqi;Liu, Nian;Cheng, Pan;Hu, Wei;Jia, Xiaodan;Guo, Qihao;Xia, Ming;Cheng, Qin;Liu, Ke;Wang, Dong. And the article was included in Macromolecular Chemistry and Physics in 2022.Category: chlorides-buliding-blocks This article mentions the following:

The pursuit of highly permeable thin-film nanocomposite (TFNC) nanofiltration (NF) membranes with desirable selectivity is an eternal topic for desalination and wastewater treatment. Herein, a facile route to engineer polyamide (PA) NF membranes is reported with a coral-reef-like thin PA active layer atop a polydopamine pre-decorated ethylene vinyl alc. copolymer (EVOH) nanofiber scaffold (EVOH-PDA) via interfacial polymerization (IP). EVOH-PDA possesses a submicron pore size and super-hydrophilic surface, which provides abundant thin water layers covering nanofibers in the IP process resulting in the PA layer with a morphol. of coral-reef-like highland surrounded by flat low-lying regions. The resultant NF membrane presents high permeance of 32.19 L m^-2h^-1bar^-1 and high rejection of 96.52% to 1000 ppm Na₂SO₄ feed solution with a stable performance against operation time and high salt concentration This work provides a new approach to fabricating PA TFNC membranes with outstanding NF performance in liquid separation applications.
