Khan, Mohammad Rizwan published the artcileQuantitative determination of methylene blue in environmental samples by solid-phase extraction and ultra-performance liquid chromatography-tandem mass spectrometry: a green approach, COA of Formula: C22H23ClN4, the publication is RSC Advances (2014), 4(64), 34037-34044, database is CAplus.

Industrial effluents with dyes may contain appreciable concentrations of materials with high COD and suspended solids, posing adverse effects to both humans and aquatic life; therefore, these effluents require quant. monitoring. In the present study, an anal. method based on solid-phase extraction (SPE) and ultra-performance liquid chromatog.-tandem mass spectrometry (UPLC-MS/MS) has been optimized for the quant. anal. of methylene blue (MB) in environmental samples. For the extraction of MB, a variety of solvents, including formic acid, were investigated to obtain optimum recovery. MB extraction using the SPE method was best achieved using methanol with 1 M formic acid. Chromatog. separation of MB and methylene violet 3RAX (MV 3RAX, internal standard) was accomplished on an Acquity BEH C₁₈ column using water (64.99%) with formic acid (0.01%) and acetonitrile (35%) in isocratic elution mode. Chromatog. separation for both MB and MV 3RAX was achieved in <2 min with good resolution and superior peak symmetry. MB and MV 3RAX were quantified with electrospray ionization coupled with MS/MS in the multiple reaction monitoring mode. Good quality parameters were achieved for instance linearity (r² > 0.999), run-to-run and day-to-day precisions with relative standard deviations of <4%, sensitivity with a low limit of detection (LOD) of 0.1 ng mL^-1 and limit of quantification (LOQ) of 0.4 ng mL^-1 were obtained. Industrial wastewater samples (paper, textile, laundry and printing press) were analyzed, and an MB level was found in between 0.36 and 1.08 μg mL^-1 with excellent recovery rates (95-99%) depending on samples.

Zaib, Sumera published the artcileEvaluation of indole-picolinamide hybrid molecules as carbonic anhydrase-II inhibitors: Biological and computational studies, HPLC of Formula: 32333-53-2, the publication is Journal of Molecular Structure (2022), 133048, database is CAplus.

The present study reported the successful synthesis and evaluation of a series of indole-picolinamide hybrids I, II [Ar = Ph, 3-CF₃C₆H₄, 3,4-di-ClC₆H₃], III, IV and V as potent inhibitors of bovine carbonic anhydrase II, a promising therapeutic target for the treatment of neurol. disorders, osteoporosis, glaucoma, cancer and obesity. Various multistep synthetic approaches were utilized to access the desired structures having exclusive sites for chem. modifications and diverse spots for biol. interactions between the ligand and enzyme. Compound I was observed as a potent inhibitor of the bovine CA-II with an IC₅₀ value of 0.0440 ± 0.009μM. The inhibition potency was about 22-fold higher than the standard drug acetazolamide (IC₅₀ = 0.9618 ± 0.180μM). Several relevant structure-activity relationships were deduced that enlighten the crucial role of substituents as well as the key pharmacophores involved in the inhibition process. Mol. docking tools reinforced the in vitro assay results. The most active compound I was also investigated for anticancer potential using sulforhodamine B assay and results showed two-fold efficacy against HeLa cells when compared to standard drug cisplatin (IC₅₀ = 8.045 ± 3.791μg/mL and 4.128 ± 1.473μg/mL, resp.). These findings were also confirmed by flow cytometry and comet tests. Moreover, fluorescence microscopy with DAPI staining revealed apoptosis as a mechanism of cancer cell death.

Emami, Leila published the artcileNovel N-substituted isatin-ampyrone Schiff bases as a new class of antiproliferative agents: Design, synthesis, molecular modeling and in vitro cytotoxic activity, COA of Formula: C7H6Cl2, the publication is Journal of Heterocyclic Chemistry (2022), 59(7), 1144-1159, database is CAplus.

Thirteen novel isatin-ampyrone Schiff bases derivatives such as I [X = H, Cl; R = H, 3-F, 4-OMe, etc.] were synthesized by the reaction of isatins and benzyl halides followed by condensation with ampyrone. In vitro cytotoxic activity of these new Schiff bases against three human tumor cell lines (MCF-7, A549, and SCOV3) as well as normal breast cell line (MCF-10A) were evaluated by MTT assay. Structure-activity relationship of the tested compounds revealed that chlorine group at C-5 position of the isatin ring significantly increased the cytotoxic activity. This study generally led to introduce a highly active mol. I [X = Cl; R = 3-Cl] with IC₅₀ values of 5.12, 25.5, and 12.9μM, on MCF-7, A549, and SCOV3, resp. Furthermore, mol. docking studies of the synthesized compounds were also done to investigate their binding modes to toward VEGFR-2 and JNK3-MAP kinase as the main targets for isatin-containing anticancer agents. Binding free energy values of the compounds showed pos. correlation with their cytotoxic activities. To confirm the docking results, mol. docking simulations of potent compound I [X = Cl; R = 3-Cl] against VEGFR-2 and JNK3 MAP kinase were also performed. According to the cytotoxic results and in silico ADMET predictions together, I [X = Cl; R = 3-Cl] could be considered as a potent candidate for the future anticancer studies.

Goldberg, Frederick W. published the artcileGeneral synthetic strategies towards N-alkyl sulfoximine building blocks for medicinal chemistry and the use of dimethylsulfoximine as a versatile precursor, SDS of cas: 7080-50-4, the publication is Tetrahedron (2014), 70(37), 6613-6622, database is CAplus.

The sulfoximine group has great potential as a substituent in drug discovery, as evidenced by two new clin. candidates, and can be viewed as an isosteric alternative to the commonly used sulfone. Our aim was to improve the accessibility of this group by synthesizing a diverse range of S-alkyl and N-alkyl sulfoximine building blocks with procedures that are applicable on a practical scale (>10 g). In particular, synthesis of the less well exploited N-alkyl sulfoximines and the use of dimethylsulfoximine as a versatile, com. available precursor is discussed.

The present work describes the synthesis of alkyl substituted N,4-di-Ph thiazole-2-amines (I) and (II) through a three step pathway. Further, the structures were confirmed by single crystal X-ray diffraction studies which revealed that compound I crystallizes in triclinic system with P-1 space group whereas compound II crystallizes as monoclinic with P2₁/c space group. The asym. unit consists of only one mol. in both the structures. The study of torsional angles of compound I and compound II indicated that S1 and C4 are cis to each other whereas N2 and C4 are trans. A detailed anal. of intermol. hydrogen bonding interactions has been performed. Also their C-H···π and π···π stacking interactions have been explored using Hirshfeld surface anal. and their 2D fingerprint plots. The most significant contributions in both the compounds are due to H···H interactions which also account for their stability.

Hydrocarbon-bonded stationary phases were prepared by reacting CH₃(CH₂)_nSiMeCl₂, where n = 7, 10, 14, and 17, with silica and were investigated and compared with phases obtained by the reaction of silica with alkyltrichlorosilanes. The reversed-phase chromatog. of halobenzenes with aq MeOH as mobile phase showed a linear relationship between the capacity ratios k‘ and the amount of C in the phases in all cases. The alkylmethyl phases were superior to the alkyl phases; capacity ratios and selectivities were increased and the efficiencies, with one exception, were higher. The improved properties are discussed in relation to residual silanol groups on the stationary phase surface.
