Synthesis, molecular modeling and anti-cancer evaluation of a series of quinazoline derivatives

Quinazolines were surveyed as biologically relevant moieties against different cancer cell lines, so in the present study, we analyzed novel derivatives as target-oriented chemotherapeutic anti-cancer drugs. A series of 3-substituted 2-thioxo-2,3-dihydro-1H-quinazolin-4-ones 4a-e were synthesized via the reaction of 2-aminobenzoic acid (1) with isothiocyanate derivatives 2a-e. S-alkylation and S-glycosylation were carried via the reaction of 4a-e with alkyl halides and alpha-glycopyranosyl bromides 7 a, b under anhydrous alkaline and glycoside conditions, respectively. The S-alkylated and S-glycosylated structures, and not that of the N-alkylated and N-glycosylated isomers, have been selected for the products. Conformational analysis has been studied by homo- and heteronuclear two-dimensional NMR methods (DQF-COSY, HMQC, and HMBC). The S site of alkylation and glycosylation were determined from the H-1, C-13 heteronuclear multiple-quantum coherence (HMQC) experiments. All derivatives were subjected to molecular docking calculations, which selected some derivatives (5n, 8c, 8g, 9c, and 9a) as promising ones based on their excellent binding affinities towards the EGFR tyrosine kinase molecular target. The in vitro cytotoxic activity against MCF-7 and HepG2 cell lines showed effective anti-proliferative activity of the analyzed derivatives with lower IC50 values especially 9a with IC50 = 2.09 and 2.08 mu M against MCF-7 and HepG2, respectively, and their treatments were safe against the normal cell line Gingival mesenchymal stem cells (GMSC). Moreover, RT-PCR reaction investigated the apoptotic pathway for the compound 9a, which activated the P53 genes and its related genes. So, further work is recommended for developing it as a chemotherapeutic drug.

miR-149 inhibits cell proliferation and enhances chemosensitivity by targeting CDC42 and BCL2 in neuroblastoma

Background Neuroblastoma (NB) is one of most common childhood tumors with high mortality among children worldwide. microRNAs (miRNAs) have been reported to play essential roles in the pathogenesis and therapeutics of NB. However, the role of miR-149 and its mechanism remain poorly understood. Main methods The expression levels of miR-149, cell division cycle 42 (CDC42) and B-cell lymphoma 2 (BCL2) were measured in NB tissues or cells by quantitative real-time polymerase chain reaction or western blot. Cell proliferation was measured by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) and colony formation assays. Cell apoptosis was detected by flow cytometry. Chemosensitivity of NB cells to doxorubicin (Dox) was analyzed by MTT assay. The interaction between miR-149 and CDC42 or BCL2 was explored by luciferase activity and RNA immunoprecipitation analyses. Results Our data indicated that low expression of miR-149 was displayed in NB tissues and cells and associated with poor survival rate. Overexpression of miR-149 inhibited cell proliferation and colony formation but promoted cell apoptosis and chemosensitivity to Dox in NB cells. Moreover, CDC42 and BCL2 were targeted by miR-149. Additionally, CDC42 and BCL2 mRNA levels were elevated in NB tissues and cells and restoration of CDC42 or BCL2 reversed the regulatory effect of miR-149 on NB progression. Conclusion Our data suggested that miR-149 suppressed cell proliferation and improved Dox chemosensitivity by regulating CDC42 and BCL2 in NB, providing a novel avenue for treatment of NB.

New perspective of Br-‘s role on NDMA formation from daminozide (DMNZD) during ozonation

N-nitrosodimethylamine (NDMA) has recently been discovered to generate from daminozide (DMNZD) during ozonation. Moreover, its formation is affected by the presence of bromine ion (Br-) in water, but the mechanism is still unclear. In this study, the effect of Br- on NDMA formation from DMNZD during ozonation at various oxidation conditions (ozone dosages, pH) and distinct water parameters was studied. In addition, the transformation pathways with/without Br- were determined. The results demonstrated that low levels of Br- promoted NDMA formation from DMNZD during ozonation. When Br- dosages increased from 0 to 1 mu M, the concentration of NDMA augmented from 138 to 195.5 mu g/L. However, when Br- concentration raised to 100 mu M, NDMA amounts dropped to 80 mu g/L. Increasing pH can raise the ratio of deprotonated DMNZD no matter with or without Br-, and promote its reaction with O-3 molecular to achieve the maximum NDMA formation at pH = 7. The amounts of NDMA decreased dramatically (from 155 to 74 mu g/L) when HCO3- dosages increased from 0 to 160 mu M with 0.1 mu M Br-, however, its concentration increased remarkably (from 155 to 225 mu g/L) with increasing SO42- (from 0 to 20 mu M). Low levels of HA (0.1-0.2mg/L) boosted NDMA formation while relatively abundant of HA (>= 0.4 mg/L) suppressed its formation. In addition, the presence of NOM inhibited NDMA formation from DMNZD during ozonation no matter Br- existed or not. Based on the results of LC/MS/MS, GC/MS and IC-MS, the transformation pathways of DMNZD with/without Br(-)during ozonation were proposed. This study provided new insights into the role of Br- on NDMA formation from typical amine compounds during ozonation. (C) 2019 Elsevier B.V. All rights reserved.

Effects of genistein on lipopolysaccharide-induced injury of mouse alveolar epithelial cells and its mechanism

Alveolar and bronchial epithelial cells have critical functions in acute respiratory distress syndrome progress. Genistein could protect the lungs from acute lung injury, however, whether genistein protects the alveolar epithelial cells from LPS-induced injury was less studied. Spectrophotometric method 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide (MTT) and enzyme-linked immunosorbent assay (ELISA) were performed to detect cell viability and levels of tumor necrosis factor-alpha (TNF-alpha), interleukin-1 beta (IL-1 beta), and IL-6. Flow cytometry and western blot assay were performed to detect cells apoptosis and protein levels. In LPS-induced model of mouse lung epithelial (MLE)-12 cells, PBEF (proinflammatory cytokine) expression, and cell apoptosis were increased and cell viability was decreased, whereas NF-kappa B was activated and expression levels of TNF-alpha, IL-1 beta, and IL-6 were increased. However, genistein partly reversed the effect of LPS, and it plays a protective role in lung injury by reducing expression of PBEF, inhibiting the activation of NF-kappa B and alleviating inflammatory response of cells.

Facile and rapid ultrasound-mediated synthesis of spherical mesoporous silica submicron particles with high surface area and worm-like mesoporosity

Here, a facile and rapid ultrasound-mediated synthesis at ambient conditions is proposed for production of novel spherical mesoporous silica submicron particles (MSP) with high specific surface area (SSA) and high worm-like mesoporosity. A one-pot synthesis was designed to involve soft-templating with cationic surfactant cetyltrimethylammonium bromide (CTAB), application of high-power ultrasound (Us) for hydrolysis/condensation of tetraethyl orthosilicate (TEOS) in methanol/NH4OH solution and vigorous magnetic stirring. Spherical MSP with worm-like mesoporous structure were produced with average particle diameter similar to 545 nm, SSA ca. 1544m(2)/g, total pore volume as high as 0.75 cm(3)/g and NLDFT pore diameter of 2.94 nm. The developed MSP hold great promise for applications e.g. H-2 storage, CO2 capture, removal of Hg from gas as well as drug delivery. (C) 2020 Elsevier B.V. All rights reserved.

A well-designed sandwich-like MS/Pd@MS hollow nanosphere for Suzuki coupling reactions of aryl bromides and arylboronic acids

A hollow core-shell nanosphere with sandwiched Pd nanoparticles between two-layered mesoporous silica was designed through layer-by-layer assembly. The nanocomposite exhibited outstanding catalytic activity and thermal stability in Suzuki coupling reactions of aryl bromides and arylboronic acids. The conversion of bromobenzene was up to 82.8% in 1 h and 68.2% in 5 min, and the sandwich structure was well-kept after running five cycles, with few Pd NPs mass loss.

Ethyl formate and phosphine fumigations on the two-spotted spider mite, Tetranychus urticae and their biochemical responses

Two spotted spider mite, Tetranychus urticae, is a polyphagous pest to a variety of plants and they are hard to be controlled due to occurrence of resistance to acaricides. In this study, biochemical evaluation after ethyl formate (EF) and phosphine (PH3) fumigation towards T. urticae might help officials to control them in quarantine purposes. PH3 fumigation controlled eggs (LC50; 0.158 mg/L), nymphs (LC50; 0.030 mg/L), and adults (LC50; 0.059 mg/L) of T. urticae, and EF effectively affected nymphs (LC50; 2.826 mg/L) rather than eggs (LC50; 6.797 mg/L) and adults (LC50; 5.836 mg/L). In a longer exposure time of 20 h, PH3 fumigation was 94.2-fold more effective tool for control of T. urticae than EF fumigant. EF and PH3 inhibited cytochrome c oxidase (COX) activity differently in both nymphs and adults of T. urticae. It confirmed COX is one of target sites of these fumigants in T. urticae and COX is involved in the respiratory chain as complex IV. Molecular approaches showed that EF fumigation completely down-regulated the expression of cox11 gene at the concentration of LC10 value, while PH3 up-regulated several genes greater than twofold in T. urticae nymphs treated with the concentration of LC50 value. These increased genes by PH3 fumigation are ndufv1, atpB, para, and ace, responsible for the expression of NADH dehydrogenase [ubiquinone] flavoprotein 1, ATP synthase, and acetylcholinesterase in insects, respectively. Lipidomic analyses exhibited a significant difference between two fumigants-exposed groups and the control, especially an ion with 815.46 m/z was analyzed less than twofold in the fumigants-treated group. It was identified as PI(15:1/18:3) and it may be used as a biomarker to EF and PH3 toxicity. These findings may contribute to set an effective control strategy on T. urticae by methyl bromide alternatives such as EF and PH3 because they have shared target sites on the respiratory chain in the pest.

CO2-switchable wormlike micelles based on a switchable ionic liquid and tetradecyl trimethyl ammonium bromide

CO2-responsive wormlike micelles based on ionic liquid 1,1,3,3-tetramethylguanidine-oleic acid (TMG-OA) and cationic surfactant tetradecyl trimethyl ammonium bromide (TTAB) was designed in this work, avoiding the volatileness and flammability of traditional wormlike micelles formed with amines. It provides a new method of preparing CO2-switchable wormlike micelles based on ionic liquid with acidic group. The ionic liquid TMG-OA was prepared by the direct neutralization reaction between TMG and HOA at the molar ratio of 1:1. Due to the excellent stability and switchability demonstrated by thermogravimetry (TGA) and pH, TMG-OA can be treated as nonvolatile surfactant with CO2-responsive acidic group. Then the worm-based viscoelastic fluid is formed by the electrostatic interaction between TTAB and TMG-OA, and the steady and dynamic rheology show that the viscoelastic fluid has CO2-switchable thinning behavior. The switchable behavior is consistent with the reversible transition of microstructure from wormlike micelles to emulsion, which were detected by the dynamic light scattering (DLS) and cryo-transmission electron microscope (Cryo-TEM). The microstructural transition is induced by the reversible conversation between TMG-OA component and HOA component upon CO2 and N-2/heat.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 615-36-1, in my other articles. Name: 2-Bromoaniline.
