And the article was included in European Journal of Medicinal Chemistry in 1999.Electric Literature of C8H7ClO3 This article mentions the following:

A number of new carboxamide derivatives, e.g. benzoxazinecarboxamides I (n = 0, 1, 2; m = 1, 0) and benzamides II (R = Et, Bu, hexyl, MeSO₂NHCH₂CH₂) were prepared The affinity of these compounds for the serotoninergic 5-HT₄ receptor was evaluated by use of radioligand-binding techniques. The agonistic activity was evaluated as the contractile effect of the ascending colon isolated from guinea-pigs. Among these compounds, II (R = MeSO₂NHCH₂CH₂) (III) showed a high affinity for the 5-HT₄ receptor. III displayed a higher affinity for 5-HT₄ receptors than the other receptors, including 5-HT₃ and dopamine D₂ receptors. In addition, III was confirmed to be a potent 5-HT₄ receptor agonist. An interaction model between III and 5-HT₄ receptor was proposed. In the experiment, the researchers used many compounds, for example, 5-Chloro-2-methoxybenzoic acid (cas: 3438-16-2Electric Literature of C8H7ClO3).

5-Chloro-2-methoxybenzoic acid (cas: 3438-16-2) 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. 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.Electric Literature of C8H7ClO3

Effect of dielectric barrier discharge cold plasma treatments on flavor fingerprints of brown rice was written by Liu, Qiang;Wu, Haijing;Luo, Ji;Liu, Jiwei;Zhao, Siqi;Hu, Qiuhui;Ding, Chao. And the article was included in Food Chemistry in 2021.SDS of cas: 57045-82-6 This article mentions the following:

A non-thermal processing method was developed to promote preservation of brown rice using dielec. barrier discharge cold plasma (DBD-CP). Physicochem. properties including free fatty acid (FFA) content, surface color change, volatile organic components (VOCs) and flavor fingerprints were evaluated in brown rice submitted to DBD-CP. FFA levels were 25.2% lower in treated samples compared to the control, and a more stable surface color was obtained at the end of the storage period. A total of 35 major VOCs could be detected in treated samples, and reduced levels of hexanal can be used as an indicator of DBD-CP treatment in brown rice during storage. Moreover, the flavor fingerprints in DBD-CP treated groups can be successfully distinguished through headspace gas chromatog. ion mobility spectrometry. Collectively, application of DBD-CP treatment could be utilized as a feasible approach to promote stabilization of brown rice and preserve flavor during storage. In the experiment, the researchers used many compounds, for example, Chloroformicacidn-nonylester (cas: 57045-82-6SDS of cas: 57045-82-6).

Chloroformicacidn-nonylester (cas: 57045-82-6) belongs to organic chlorides. An organic chloride is an organic compound containing at least one covalently bonded atom of chlorine. Their wide structural variety and divergent chemical properties lead to a broad range of names and applications. Alkyl chlorides readily react with amines to give substituted amines.

And the article was included in Medicinal Chemistry Research in 2021.COA of Formula: C19H15Cl This article mentions the following:

As 17β-estradiol and its derivatives have good affinity with estrogen receptors and have unique antitumor properties, O¹-propargyl-N⁴,N⁴-bis(2-chloroethyl)-4-aminophenol and N⁴,N⁴-dipropargyl-N¹,N¹-bis(2-chloroethyl)-1,4-phenylenediamine were resp. combined with 17β-estradiol through linkers of different lengths. These targeted novel nitrogen mustard 17β-estradiol derivatives were tested antiproliferative activity using the MTT assay. The results illustrated that these compounds were less toxicity to HL-7702 (human liver cells) and SKOV-3, though all their activity potency was moderate or weak against the MDA-MB-231, MCF-7 and BEL-7404 cell lines. The inhibitory activity of the O¹-propargyl-N⁴,N⁴-bis (2-chloroethyl)-4-aminophenol derivatives were obviously better than the N⁴-dipropargyl-N¹, N¹-bis (2-chloroethyl) -1,4-phenylenediamine derivatives against tested tumor cell lines. And three hybrids exhibited good inhibitory activity against BEL-7404 cell line (IC₅₀ = 13.5, 15.3 and 13.9μM, resp.).

Responsive Ionogel Surface with Renewable Antibiofouling Properties was written by Ye, Lijun;Chen, Fei;Liu, Jie;Gao, Aiting;Kircher, Gunnar;Liu, Wendong;Kappl, Michael;Wegner, Seraphine;Butt, Hans-Juergen;Steffen, Werner. And the article was included in Macromolecular Rapid Communications in 2019.Computed Properties of C18H37Cl This article mentions the following:

The synthesis of ionogels with a responsive, self-replenishing surface for combating biofouling is described. Ionogels are prepared by infiltrating poly(vinylidene fluoride-co-hexafluoropropylene) with binary mixtures of ionic liquids (IL): 1-octadecyl-3-methylimidazolium bis(trifluoromethyl sulfonyl)imide ([C₁₈C₁i.m.][NTf₂], m.p. T_m = 55 °C) and 1-hexyl-3-methylimidazolium bis(trifluoromethyl sulfonyl)imide ([C₆C₁i.m.][NTf₂], T_m = -9 °C). The IL mixtures release spontaneously from the gel matrix and eventually crystallize on the surface. This leads to self-replenishment of the surface of ionogels even after mech. damage. The incorporation of [C₆C₁i.m.][NTf₂] provides the antimicrobial efficacy of ionogels while the crystals of [C₁₈C₁i.m.][NTf₂] serve as a skeleton maintaining [C₆C₁i.m.][NTf₂] on the surface. By heating, the ionogel surface transforms from solid to liquid-infused state-the removal of biofilms/bacteria developed under a long time of colonization is facilitated. The antimicrobial efficacy is maintained even after several cycles of biofilm formation and detachment. This work provides an opportunity to apply ionogels as functional coatings with renewable antibiofouling properties. In the experiment, the researchers used many compounds, for example, 1-Chlorooctadecane (cas: 3386-33-2Computed Properties of C18H37Cl).

Pharmaceuticals and personal care products in the seawater around a typical subtropical tourist city of China and associated ecological risk was written by Chen, Hongzhe;Chen, Wenfeng;Guo, Huige;Lin, Hui;Zhang, Yuanbiao. And the article was included in Environmental Science and Pollution Research in 2021.Recommanded Product: 101-20-2 This article mentions the following:

Pharmaceuticals and personal care products (PPCPs) in the sea area surrounding a densely populated tourist city in southeastern China were investigated. In total, 32 PPCP pollutants classified into 23 categories were detected. Different spatial distribution patterns of PPCPs indicated possible contamination from runoff and multiple local sources. The labile-to-conservative ratios of PPCPs showed the influence of untreated domestic sewage. In addition, increased concentrations of ciprofloxacin, enrofloxacin, and erythromycin around aquaculture farms imply that aquaculture cannot be neglected as a source. The concentrations of oxytetracycline, ranitidine, ciprofloxacin, miconazole, and sulfamethizole were higher in the wet season than those in the dry season, and the difference in pharmaceutical consumption was suspected to be the main driving factor of this seasonal variation. The risk quotients calculated with the maximum concentrations of miconazole, triclosan, dehydronifedipine, and triclocarban exceeded 0.1, indicating potential moderate or high risks. Antibacterial agents in daily chems. and azole broad-spectrum antifungals were associated with the highest risks in this study; this might be another significant pollution characteristic in the sea area around this subtropical tourist city. In the experiment, the researchers used many compounds, for example, 1-(4-Chlorophenyl)-3-(3,4-dichlorophenyl)urea (cas: 101-20-2Recommanded Product: 101-20-2).

1-(4-Chlorophenyl)-3-(3,4-dichlorophenyl)urea (cas: 101-20-2) belongs to organic chlorides.

And the article was included in Organic & Biomolecular Chemistry in 2022.SDS of cas: 620-19-9 This article mentions the following:

An efficient and practical phosphine-catalyzed homo-coupling reaction of benzyl chlorides was described. The reactions proceed smoothly in the presence of CsF/B(OMe)₃ and NaH as the base, resp., to provide trans-stilbenes in good yields with a broad scope. Unsym. stilbenes was also generated from the reactions of benzyl chlorides with phosphonium salts. Several P-based key intermediates was detected by NMR and HRMS analyses, which shed light on the postulated catalytic cycle. In the presence of different bases, the transformations involve two different pathways, in which phenylcarbene and phosphonium alkoxide was considered as key intermediates, resp. The two pathways were complementary in synthesis but different in mechanisms. The synthetic utility, including gram-scale reactions and straightforward access to π-conjugated mols., was demonstrated as well. In the experiment, the researchers used many compounds, for example, 1-(Chloromethyl)-3-methylbenzene (cas: 620-19-9SDS of cas: 620-19-9).

Structure-activity Relationship Studies of Microbiologically Active Thiosemicarbazides Derived from Hydroxybenzoic Acid Hydrazides was written by Plech, Tomasz;Paneth, Agata;Kapron, Barbara;Kosikowska, Urszula;Malm, Anna;Strzelczyk, Aleksandra;Staczek, Pawel. And the article was included in Chemical Biology & Drug Design in 2015.Electric Literature of C7H3Cl2NS This article mentions the following:

Forty-five derivatives of thiosemicarbazide were synthesized, and their antibacterial activity against Gram-pos. and Gram-neg. bacteria was evaluated. Some of the described compounds exhibited interesting activity against reference strains of Gram-pos. bacteria, whereas only two derivatives had the ability to inhibit the growth of Gram-neg. species (Escherichia coli ATCC 25922, Klebsiella pneumoniae ATCC 13883, Proteus mirabilis ATCC 12453). The most potent antimicrobial activity was observed in the cases of salicylic acid hydrazide derivatives The differences in activity inspired us to conduct conformational anal. using mol. mechanics level. The obtained results suggest that the mol. geometry, especially at the N4-terminus of thiosemicarbazide skeleton, determines the antibacterial activity. Unfortunately, in opposition to what we expected, only one of the tested compounds inhibited the activity of the topoIV enzyme, and none of them was active against DNA gyrase. In the experiment, the researchers used many compounds, for example, 2,4-Dichlorophenylisothiocyanate (cas: 6590-96-1Electric Literature of C7H3Cl2NS).
