Effect of fluorine substitution of α- and β-hydrogen atoms in ethyl phenylacetate and phenylpropionate on their stereoselective hydrolysis by cultured cancer cells was written by Yamazaki, Yoshimitsu;Yusa, Shiro;Kageyama, Yu-ichi;Tsue, Hirohito;Hirao, Ken-ichi;Okuno, Hiroaki. And the article was included in Journal of Fluorine Chemistry in 1996.Recommanded Product: 7476-66-6 This article mentions the following:

(±)-Et 2-fluoro-2-phenylacetate was stereoselectively hydrolyzed by cultured cells of several rat cancer cell lines to give the carboxylic acid rich in the R enantiomer. The stereoselectivity increased for (±)-Et 2-fluoro-2-phenylpropionate (I) with all present cell lines and for (±)-Et 2-phenyl-3,3,3-trifluoropropionate with rat hepatoma McA-RH7777 cell line. The stereoselectivity was different for the different cell lines, as McA-RH7777 cells preferred (R)-I in contrast with the preference towards (S)-I by other cells such as ras oncogene-transformed rat liver Anr4 cells. These stereoselectivities were different from those for non-fluorinated (±)-Et 2-phenylpropionate. Thus fluorine atoms are recognized by ester hydrolases of cancer cells, and fluorine substitution on the acyl group will be useful for making ester-type anticancer prodrugs more specific to cancer cells. In the experiment, the researchers used many compounds, for example, Methyl 2-chloro-2-phenylacetate (cas: 7476-66-6Recommanded Product: 7476-66-6).

Methyl 2-chloro-2-phenylacetate (cas: 7476-66-6) belongs to organic chlorides. Organochlorines stimulate the central nervous system and cause convulsions, tremor, nausea, and mental confusion. Examples are dichlorodiphenyltrichloroethane (DDT), chlordane, lindane, endosulfan, and dieldrin. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control.Recommanded Product: 7476-66-6

And the article was included in Molecules in 2020.Recommanded Product: 3-(Trifluoromethyl)benzene-1-sulfonyl chloride This article mentions the following:

Novel 12N-substituted aloperine derivatives I [R = Et, 3,4,5-trimethylphenyl, oxan-4-yl, etc.; R¹ = H, Me, naphthalen-2-yl; RR¹ = -(CH₂)₄-] and 12N-N’-phenoxazinylcarbamoylmethyl aloperine, II [R² = naphthalen-1-yl, 3-(trifluoromethyl)phenyl, Ph, 4-bromo-3-(trifluoromethyl)phenyl], III [R² = Bu, 3-(trifluoromethoxy)phenyl, 3-bromophenyl, etc.]were synthesized and investigated for their inhibitory effects on collagen α1 (I) (COL1A1) promotor in human hepatic stellate LX-2 cells, taking aloperine (1) as the hit. A structure-activity relationship (SAR) study disclosed that the introduction of suitable substituents on the 12N atom might enhance the activity. Compound 12N-N’-phenoxazinylcarbamoylmethyl aloperine exhibited a good promise on down-regulating COL1A1 expression with the IC₅₀ value of 16.5μM. Its inhibitory activity against COL1A1 was further confirmed on both mRNA and protein levels. Meanwhile, it effectively inhibited the expression of other fibrogenic proteins, such as transforming growth factor β1 (TGF-α1) and smooth muscle actin (α-SMA). It also exhibited good in vivo safety profile with the oral LD₅₀ value of 400 mg kg^-1 in mice. The results initiated the anti-liver fibrogenic study of aloperine derivatives, and the key compound 12N-N’-phenoxazinylcarbamoylmethyl aloperine was selected as a novel lead for further investigation against liver fibrogenesis.

Synergistic degradation of Methylene Blue by novel Fe-Co bimetallic catalyst supported on waste silica in photo-Fenton-like system was written by Quiton, Khyle Glainmer N.;Lu, Ming-Chun;Huang, Yao-Hui. And the article was included in Sustainable Environment Research in 2022.Product Details of 61-73-4 This article mentions the following:

In this present study, a novel method to fabricate bimetallic Fe-Co catalyst supported on waste silica was investigated for the photo-Fenton-like (PFL) degradation of Methylene Blue (MB) dye. The uniqueness of this work is on the preparation of the catalyst via fluidized-bed crystallization (FBC) process. Under the optimum conditions of initial pH of 3.0, 3.0 mM of H2O2, and 1.0 g L-1 of FBC-derived Fe-Co/SiO2 catalyst (fFCS), the maximum response for the decoloration and mineralization efficiencies of 20 mg L-1 of MB in 60 min were 100 and 65%, resp. Compared to the impregnated Fe-Co/SiO2 catalyst, the fFCS catalyst exhibited comparable decoloration and mineralization efficiencies, and relatively lower metal leaching for both iron and cobalt. Superoxide radical was unveiled to be the dominant reactive oxygen species in the PFL system over the fFCS catalyst. The catalysts were characterized by Fourier Transform IR spectroscopy, Energy Dispersive X-ray spectroscopy and SEM. The results show the successful incorporation of iron and cobalt on the surface of the SiO2 support material.

Organic chlorides are compounds containing a carbon-chlorine bond, which are widely used in the oil field as a wax dissolver. Organochlorine compounds are lipophylic, meaning they are more soluble in fat than in water. This gives them a high tenancy to accumulate in the food chain (biomagnification).Reference of 63624-28-2

Scalable Pillar[5]arene-Integrated Poly(arylate-amide) Molecular Sieve Membranes to Separate Light Gases was written by Song, Woochul;Park, Jaesung;Dasgupta, Subhadeep;Yao, Chenhao;Maroli, Nikhil;Behera, Harekrushna;Yin, Xinyang;Acharya, Durga P.;Zhang, Xueyi;Doherty, Cara M.;Maiti, Prabal K.;Freeman, Benny D.;Kumar, Manish. And the article was included in Chemistry of Materials in 2022.Formula: C9H3Cl3O3 This article mentions the following:

Mol. sieve membranes and their analogs could potentially transform energy-intensive gas separation processes. However, many such membranes suffer from either limited processability or phys. stability including plasticization of semi-flexible microstructures. Here, we report on a new variation of all-polymer-based mol. sieve membranes that could tackle these specific challenges. These membranes were prepared by the interfacial polymerization of pillar[5]arene, m-phenylenediamine, and trimesoyl chloride to create characteristic poly(arylate-amide) heteropolymer microstructures. Pillar[5]arenes were crosslinked into the films with net weight fractions of up to ~47%, wherein the 4.7 Å cavities of pillar[5]arenes were interconnected with ~2.8 Å apertures. These microstructures provided preferred permeation paths for smaller mols. (He and H₂) among the tested light gases (He, H₂, CO₂, O₂, N₂, and CH₄) and resulted in significant mol. sieving effects with representative pure gas selectivities of 32 (H₂/CO₂), 150 (CO₂/CH₄), 4600 (H₂/CH₄), 13 (O₂/N₂), and 4.7 (N₂/CH₄) at 35°C and 10 atm. These separation factors outperform most polymer-based gas separation membranes, while providing membrane features such as thin film barriers, cross-linked polymer backbones, and excellent processability resulting from interfacial polymerization that are critical for large-scale operations. In the experiment, the researchers used many compounds, for example, Trimesoylchloride (cas: 4422-95-1Formula: C9H3Cl3O3).

Further, the compounds were screened for their antimicrobial and antiinflammatory activity against DNA gyrase A, COX-1 and COX-2 by using mol. docking approach. The bioactivity and toxicity risks were analyzed through Mol. Operating Environment. The results revealed that the compounds 8b, 8c, 8d, 8e, 8f, 8g and 9a exhibited the most promising antimicrobial activity against all the bacterial and fungal strains tested when compared with the standard drugs streptomycin and fluconazole.
