Synthesis and antibacterial activity of thiazolo-, oxazolo-, and imidazolo[3,2-a][1,8]naphthyridinecarboxylic acids was written by Kondo, Hirosato;Taguchi, Masahiro;Inoue, Yoshimasa;Sakamoto, Fumio;Tsukamoto, Goro. And the article was included in Journal of Medicinal Chemistry in 1990.Application of 96568-04-6 This article mentions the following:

Title compounds I (R = H, X = S; R = Me, X = O; R = H, X = NMe) were synthesized from dichlorofluoropyridyloxopropionate II and evaluated for antibacterial activity in vitro and for inhibitory activity against DNA gyrase of Escherichia coli K-12 C600. I (R = H, X = S) exhibited antibacterial activity comparable to that of ofloxacin and enoxacin against Gram-pos. and Gram-neg. bacteria and displayed antibacterial activity superior to that of I (R = Me, X = O; R = H, X = NMe), whereas, the antibacterial activity of I (R = Me, X = O) was greater than that of I (R = H, X = NMe). The DNA gyrase inhibitory activities of I paralleled their in vitro antibacterial activity. In the experiment, the researchers used many compounds, for example, Ethyl 3-(2,6-Dichloro-5-fluoro-3-pyridyl)-3-oxopropionate (cas: 96568-04-6Application of 96568-04-6).

Ethyl 3-(2,6-Dichloro-5-fluoro-3-pyridyl)-3-oxopropionate (cas: 96568-04-6) 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. Aliphatic organochlorides are often alkylating agents as chlorine can act as a leaving group, which can result in cellular damage.Application of 96568-04-6

Synthesis of quinolin-2-one alkaloid derivatives and their inhibitory activities against HIV-1 reverse transcriptase was written by Cheng, Pi;Gu, Qiong;Liu, Wei;Zou, Jian-Feng;Ou, Yang-Yong;Luo, Zhong-Yong;Zeng, Jian-Guo. And the article was included in Molecules in 2011.Recommanded Product: 18437-66-6 This article mentions the following:

Based on an established common pharmacophore of HIV-1 non-nucleoside reverse transcriptase inhibitors (NNTTIs), several quinolinone derivatives were designed and the synthesis of the target compounds [4-(phenylthio)-2(1H)-quinolinone derivatives, 4-(phenoxy)-2(1H)-quinolinone derivatives, 4-phenyl-2(1H)-quinolinone derivatives] was achieved using chloroquinolines as key intermediates. The title compounds were assayed for their in-vitro activity against HIV-1 reverse transcriptase (RT) for the first time and it was discovered that some of the tested compounds were active against HIV-1 RT [RNA-dependent deoxyribonucleate nucleotidyltransferase (human immunodeficiency virus 1)]. Two compounds displayed inhibitory activities with IC₅₀ values of 0.21 and 0.15 μM, resp., with a mode of interaction with RT residues of the allosteric pocket similar to that of Efavirenz. In the experiment, the researchers used many compounds, for example, tert-Butyl (4-chlorophenyl)carbamate (cas: 18437-66-6Recommanded Product: 18437-66-6).

tert-Butyl (4-chlorophenyl)carbamate (cas: 18437-66-6) belongs to organic chlorides. Chlorination modifies the physical properties of hydrocarbons in several ways. These compounds are typically denser than water due to the higher atomic weight of chlorine versus hydrogen. 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).Recommanded Product: 18437-66-6

Removal of organic pollutants from super heavy oil wastewater by lignite activated coke was written by Tong, Kun;Zhang, Yihe;Fu, Dan;Meng, Xianghai;An, Qi;Chu, Paul K.. And the article was included in Colloids and Surfaces, A: Physicochemical and Engineering Aspects in 2014.Application In Synthesis of 1-Chlorooctadecane This article mentions the following:

Extraction of organic pollutants from super heavy oil wastewater (SHOW) by lignite activated coke (LAC) is investigated. The factors studied include the exposure time, temperature, and different pollutant concentrations in the wastewater. The equilibrium adsorption data are analyzed by the Langmuir, Freundlich, Temkin, and Dubinin-Radushkevich (D-R) isotherms. The best match is obtained by the Freundlich isotherm and a chem. mechanism is suggested based on the D-R model. The adsorption kinetics follows the pseudo second order model and the mass transfer model suggests that external and intra-particle diffusion influences the adsorption process. Thermodn. studies show that adsorption of organic materials is spontaneous at high temperature (303 and 313 K) but not so at lower temperature (293 K) and reveals an endothermic process and increase in randomness during adsorption. The pilot dynamic adsorption test indicates that LAC can remove not only organic pollutants such as COD, NH₃-N, oils, but also inorganic pollutants such as Mg²⁺, Ca²⁺, and salts. In the experiment, the researchers used many compounds, for example, 1-Chlorooctadecane (cas: 3386-33-2Application In Synthesis of 1-Chlorooctadecane).

1-Chlorooctadecane (cas: 3386-33-2) belongs to organic chlorides.

Alkyl chlorides readily undergo attack by nucleophiles.Application In Synthesis of 1-Chlorooctadecane

Synthesis of Furans and Pyrroles from 2-Alkoxy-2,3-dihydrofurans Through a Nucleophilic Substitution-Triggered Heteroaromatization was written by Liu, Changhui;Zhou, Li;Huang, Wenbo;Wang, Man;Gu, Yanlong. And the article was included in Advanced Synthesis & Catalysis in 2016.Reference of 96568-04-6 This article mentions the following:

An effective method to synthesize α-functionalized furan and pyrrole derivatives was developed using 2-alkoxy-2,3-dihydrofurans as modular precursors. This protocol featured a previously unreported tandem nucleophilic substitution/heteroaromatization reaction. Nucleophiles such as indole, α-oxoketene dithioacetal, trimethoxybenzene, and dimethoxynaphthalene can react readily with 2-alkoxy-2,3-dihydrofurans to afford α-functionalized five-membered ring heterocycles in the presence of acid catalysts, such as copper bromide and iron chloride. The mechanism of the reaction was also discussed, in which the first step, nucleophilic substitution, is the key in triggering the succeeding heteroaromatization. This method can also be extended to the synthesis of dihydrothiophenes. In the experiment, the researchers used many compounds, for example, Ethyl 3-(2,6-Dichloro-5-fluoro-3-pyridyl)-3-oxopropionate (cas: 96568-04-6Reference of 96568-04-6).

CON4EI: Selection of the reference chemicals for hazard identification and labelling of eye irritating chemicals was written by Adriaens, E.;Alepee, N.;Kandarova, H.;Drzewieckac, A.;Gruszka, K.;Guest, R.;Willoughby, J. A. Sr.;Verstraelen, S.;Van Rompay, A. R.. And the article was included in Toxicology In Vitro in 2017.SDS of cas: 96568-04-6 This article mentions the following:

Assessment of the acute eye irritation potential is part of the international regulatory requirements for testing of chems. In the past, several prospective and retrospective validation studies have taken place in the area of serious eye damage/eye irritation testing. Success in terms of complete replacement of the regulatory in vivo Draize rabbit eye test has not yet been achieved. A very important aspect to ensure development of successful alternative test methods and/or strategies for serious eye damage/eye irritation testing is the selection of appropriate reference chems. A set of 80 reference chems. was selected for the CEFIC-LRI-AIMT6-VITO CON4EI (CONsortium for in vitro Eye Irritation testing strategy) project, in collaboration with Cosmetics Europe, from the Draize Reference Database published by Cosmetics Europe based on key criteria that were set in their paper (e.g. balanced by important driver of classification and phys. state). The most important goals of the CON4EI project were to identify the performance of eight in vitro alternative tests in terms of driver of classification and to identify similarities/differences between the methods in order the build a successful testing strategy that can discriminate between all UN GHS categories. This paper provides background on selection of the test chems. In the experiment, the researchers used many compounds, for example, Ethyl 3-(2,6-Dichloro-5-fluoro-3-pyridyl)-3-oxopropionate (cas: 96568-04-6SDS of cas: 96568-04-6).
