The degradation of colored dyes through the photocatalysis process has been proved to be a promising technique for wastewater treatment. Herein, we report the synthesis of cerium titanate (CeTiO₄) nanoparticles (NPs) immobilized with a blend of caffeine (Caf) grafted alginate (Alg) biopolymer resulting in the formation of Caf-Alg@CeTiO₄ bionanocomposite (BNC) material. The material was characterized by various instrumental techniques such as Fourier transform IR (FTIR), X-ray diffraction (XRD), Scanning electron microscope- Electron dispersive X-ray (SEM-EDX), Transmission electron microscope (TEM), Brunauer, Emmett and Teller (BET), XPS and UV-visible (UV-VIS) spectroscopy. The XRD data and results suggested the presence of anatase phase of TiO₂ which is a little bit mitigated due to doping of Ce⁴⁺ at the grain sides resulting in an orthorhombic structure with 16.23 nm crystallite size. Further, the material was probed as a photocatalyst to degrade methylene blue (MB) under visible solar radiation. The antagonistic and synergistic effects of reaction variables like irradiation time (30-60 min), pH (6-10), MB concentration (50-100 mg L^-1), and catalyst dose (0.5-1.5 g L^-1) on MB degradation was designed by a combination of statistical model response surface methodol. (RSM) and Box-Behnken design (BBD). The statistically optimized results with min. error were computed as irradiation time as 50 min, pH as 6.6, MB concentration as 98.60 mg L^-1 and catalyst dose as 0.57 g L^-1 with maximum MB degradation of 98%. The kinetic studies revealed that the photocatalytic degradation process followed pseudo-first-order path associated with Langmuir- Hinshelwood (L-H) kinetic model. The values of intrinsic coefficient (kr) and adsorption constant (ks) were found to be 0.22 mg L^-1 min^-1 and 0.48 L mg^-1 resp. Trapping experiments revealed peroxide radical (O^–·₂ radicals) as primary reactive oxygen species (ROS) for 98% degradation of MB under visible solar radiation. In the experiment, the researchers used many compounds, for example, 3,7-Bis(dimethylamino)phenothiazin-5-ium chloride (cas: 61-73-4Related Products of 61-73-4).

Nitrophenyl Derivatives as Aldose Reductase Inhibitors was written by Costantino, Luca;Ferrari, Anna Maria;Gamberini, Maria Cristina;Rastelli, Giulio. And the article was included in Bioorganic & Medicinal Chemistry in 2002.SDS of cas: 16588-16-2 This article mentions the following:

Nitrophenyl derivatives were recently discovered as a new class of ALR2 inhibitors by means of docking and database screening of the National Cancer Institute database of organic mols. The nitro group was predicted to bind to the Tyr48 and His110 active site residues of the enzyme, the site where acidic ALR2 inhibitors such as carboxylic acids bind in their anionic form. Given the novelty of these compounds, we decided to expand their structure-activity relationships by synthesizing and testing a series of derivatives and the corresponding compounds having a carboxylic group instead of the nitro moiety; the results obtained were rationalized by means of docking and mol. dynamics simulations. On the whole there is an agreement between inhibitory data and the results of mol. modeling experiments, supporting the hypothesized binding mode of these compounds In the experiment, the researchers used many compounds, for example, Ethyl 4-chloro-3-nitrobenzoate (cas: 16588-16-2SDS of cas: 16588-16-2).

Quinolone antibacterials containing the new 7-[3-(1-aminoethyl)-1-pyrrolidinyl] side chain: the effects of the 1-aminoethyl moiety and its stereochemical configurations on potency and in vivo efficacy was written by Domagala, John M.;Hagen, Susan E.;Joannides, Themis;Kiely, John S.;Laborde, Edgardo;Schroeder, Mel C.;Sesnie, Josephine A.;Shapiro, Martin A.;Suto, Mark J.;Vanderroest, Steven. And the article was included in Journal of Medicinal Chemistry in 1993.Computed Properties of C10H8Cl2FNO3 This article mentions the following:

A series of stereochemically pure 7-[3-(1-aminoethyl)-1-pyrrolidinyl]-1,4-dihydro-4-oxoquinoline and 1,8-naphthyridine-3-carboxylic acids, with varied substituents at the 1-, 5-, and 8-positions, were synthesized to study the effects of the 7-[3-(1-aminoethyl)-1-pyrrolidinyl] moiety on potency and in vivo efficacy relative to the known 7-[3-(aminomethyl)-1-pyrrolidinyl] derivatives The antibacterial efficacies of the target compounds and their relevant reference agents were determined in vitro using an assortment of Gram-neg. and Gram-pos. organisms and in vivo using Escherichia coli and Streptococcus pyogenes mouse infection models. The effects of the 7-[3-(1-aminoethyl)-1-pyrrolidinyl] moiety were also examined at the level of the target enzyme by employing a DNA-gyrase supercoiling inhibition assay. Selected compounds were further evaluated for potential phototoxic and clastogenic liabilities using a phototoxicity mouse model and an in vitro mammalian cell cytotoxicity assay. It was found that the differences in in vitro antibacterial activity between the stereoisomers were significantly greater than previously reported for other optically pure 3-substituted pyrrolidinyl side chains. Relative to their 7-[3-(aminomethyl)-1-pyrrolidinyl] analogs, the (3R,1S)-3-(1-aminoethyl)pyrrolidines generally conferred a 2-4-fold increase in Gram-pos. in vitro activity and an average of 10-fold improvement in oral efficacy. The level of phototoxicity and cytotoxicity of the product quinolones was ultimately determined by the combined influence of the 7-[3-(1-aminoethyl)-1-pyrrolidinyl] side chains and the other quinolone substituents. From this study, several compounds were identified with outstanding antibacterial activity and low degrees of phototoxicity and mammalian cell cytotoxicity. One such agent, R,S–I (PD 140248), showed the best overall blend of safety and efficacy.

And the article was included in European Journal of Medicinal Chemistry in 2020.Electric Literature of C8H9ClO4S This article mentions the following:

In order to identify new aromatase enzyme inhibitors, thirty aryl sulfonamide derivatives containing an indole nucleus have been synthesized. The enzyme inhibition assay showed that four compounds inhibit aromatase in the sub-micromolar range. Loading concentrations of these four compounds were afterwards tested for cell viability and cytotoxicity on MCF7 human breast cancer cells, revealing a time- and dose-dependent decrease of active metabolizing cells over the time of the culture (0-72 h), starting from a concentration of 100μM. Likewise LDH released raised up to 40% at early time of exposures (24 h). Finally, the docking study showed that the best active compounds efficiently bound in the active site of the aromatase; high values of HBD and low levels of HBA are the principal requirement evidenced by the QSAR model.

New kinds of Pd-coordinating azo-based liquid crystalline polysilsesquioxanes, Pd-H-FBA and Pd-C-FBA, have been synthesized first by hydrosilylation reactions of a vinyl-terminated mesomorphic azo compound with ladder-like homopolyhydrosilsesquioxane (H-T) and copolymethylhydrosilsesquioxane (MH-T) to produce fishbone-like, azo-based liquid crystalline polysilsesquioxanes H-FBA and C-FBA, resp., followed by a further ortho-palladation reaction with palladium chloride. The mesomorphic properties have been investigated by DSC, optical polarizing microscopy and temperature-variable x-ray diffraction. Their clearing temperatures, T_cl, are much higher and the mesophase ranges, ΔT, are much wider than those of the corresponding comb-like polymers with a single main chain,i.e., by more than 100°.
