Thirty-four seco-3’R,4’R-disubstituted-2′,2′-dimethyldihydropyrano[2,3-f]chromone (seco-DSP) derivatives were designed, synthesized and evaluated for chemo-reversal activity when combined with paclitaxel or vincristine in P-gp overexpressing A2780/T and KB-VIN drug-resistant cancer cell lines. Most of the compounds displayed moderate to significant MDR reversal activities. Compound 7e showed the most potent chemo-sensitization activity with more than 1471 reversal ratio at a concentration of 10 mu M, which was higher than verapamil (VRP) (212-fold). Unexpectedly the newly synthesized compounds did not show chemosensitization activities in a non-P-gp overexpressing cisplatin resistant human ovarian cancer cell line (A2780/CDDP), implying that the MDR reversal effects might be associated with P-gp overexpression. Moreover, the compounds did not exhibit significant anti-proliferative activities against non-tumorigenic cell lines (HUVEC, HOSEC and T29) compared to VRP at the tested concentration and might be safer than VRP. In preliminary pharmacological mechanism studies, the compounds increased accumulation of DOX and promoted P-gp ATPase activity in A2780/T cell lines. Western blot analysis indicated they did not affect the expression level of P-gp in the tested MDR cell lines. Thus, further studies on these seco-DSP derivatives are merited with the goal of developing a desirable chemosensitizer drug candidate. (C) 2020 Elsevier Masson SAS. All rights reserved.

Etoxazole is a newly registered and widely used acaricide. However, its metabolites were not fully understood and might exhibit similar or even higher toxicity than parent compound. Therefore, in this study, the metabolites of etoxazole in citrus, soil and earthworms were firstly identified by an ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC-QTOF/MS). Four potential metabolites in citrus, 11 in soil, and 8 in earthworms were determined. These metabolites were then further structural elucidated based on the fragment pathways, and accurate mass measurement. The distributions of etoxazole and its main metabolites (M1, M2, M3, M4 and M5) which were identified as the dehydrogenation, hydrolysis, oxidation products of etoxazole (M0) were also monitored in citrus, soil and earthworms at different exposure periods. The 45 days exposure experiment showed that M0 gradually decreased in citrus and soil samples by 80% and 28% of the initial amounts, respectively. In earthworm samples, M0 accumulated in the bodies of the worms during 24 days exposure and then decreased with time. The dissipation rate of etoxazole were citrus > earthworms > soil. Concentrations of M1 and M3 in soil were found continuously increased with time during the experimental period. Moreover, the persistence of M1 in earthworm samples was also observed. Great attention should be paid to these two compounds due to their potential risks to both environmental and human health. (C) 2019 Published by Elsevier Ltd.

The reaction of zirconium salts with meso-tetra(4-carboxyphenyl)porphyrin (TCPP) in the presence of different modulators results in the formation of a diverse set of metal-organic frameworks (MOFs), each displaying distinct crystalline topologies. However, the synthesis of phase-pure crystalline frameworks remains challenging due to the concurrent formation of different polymorphs. The acidity and concentration of the modulator greatly influence the outcome of the MOF synthesis. By systematically varying these two parameters, selective framework formation can be achieved. In the present study, we aimed to elucidate the effect of modulator on the synthesis of zirconium-based TCPP MOFs. With the help of powder X-ray diffraction and scanning electron microscopy, modulator candidates and the optimal synthetic conditions yielding phase-pure PCN-222, PCN-223, and MOF-525 were identified. H-1 nuclear magnetic resonance analysis, thermogravimetric analysis, and N-2 gas sorption measurements were performed on select MOFs to gain insight into the relationship between their defectivity and modulator properties.

Application In Synthesis of 2,5-Dimethoxybenzaldehyde. I found the field of Chemistry very interesting. Saw the article Synthesis of new alpha-aminophosphonates using nanoscale nickel-based metal-organic framework as a heterogeneous catalyst and their antibacterial activity published in 2020.0, Reprint Addresses Shimpi, NG (corresponding author), Univ Mumbai, Lab Mat Sci, Dept Chem, Mumbai 400098, Maharashtra, India.. The CAS is 93-02-7. Through research, I have a further understanding and discovery of 2,5-Dimethoxybenzaldehyde.

An elegant approach was presented for the synthesis of novel alpha-aminophosphonates: a three-component one-pot condensation of 3-(trifluoromethyl)aniline, substituted aromatic aldehydes, and diethyl phosphite using a nickel-based metal-organic framework (Ni-MOF). The Ni-MOF was synthesized using 4,4 ‘-biphenyldicarboxylic acid and further characterized using various techniques such as X-ray diffraction, Fourier-transform infrared, thermogravimetry/differential thermal analysis, Brunauer-Emmett-Teller, and field-emission scanning electron microscopy analyses. Ni-MOF seems to be an eco-friendly, an easily recyclable, and heterogeneous catalyst up to the eighth run with minimal reduction in its catalytic activity. The synthesized alpha-aminophosphonates were also investigated for antibacterial and antioxidant activities. In few cases, compounds 4a-4x show similar as well as higher antibacterial activity. Among the synthesized alpha-aminophosphonates, 4a-4x had more potent antibacterial activity against pathogenic bacteria while compounds 4h, 4m, 4n, 4q, 4u, 4v, and 4w exhibited significant antioxidant activity.

The cyanosilylation of aromatic aldehydes and heteroaryl aldehydes with trimethylsilyl cyanide (TMSCN) is efficiently catalyzed by an iron complex of the type {[3-isopropyl-1-(1R-phenylethyl)imidazol-2-ylidene]Fe(CO)(2)}I (3) in presence of UV light (lambda = 294 nm) in moderate to excellent yields under ambient temperature. The heteroaryl aldehydes exhibited higher yields than the aromatic ones, and the aromatic aldehydes, bearing electron donating groups (EDG), exhibited higher yields over the ones with the electron withdrawing groups (EWG). A proposed catalytic cycle initiates with an active species (A), formed by the dissociation from the iron complex (3), and proceeds via an aldehyde activated species (B), and that upon reaction with TMSCN gives the desired cyanosilylated product. Quite significantly, the initial active iron species (A) and the iron-bound alpha-cyanobenzyloxy species (C) have been detected by mass spectrometry. Additionally, the formation of species (C) was further corroborated by the observation of the formation of TMSI in Si-29 NMR experiment.

This article presents a detailed comprehensive investigation of the ortho fluoro- and chloro- substituted benzoic acids both, as isolated molecules and in the crystalline phase. Quantum chemical calculations performed within the density functional theory (DFT) formalism are used to investigate the potential energy landscapes of the molecules, taking into special consideration the effects of the interactions between the carboxylic group and the ortho halogen substituents, as well as the nature of these later on the structure and properties of the investigated systems. The structures of the relevant conformers of the molecules are discussed in comparative terms, and used to rationalize experimental data obtained for the compounds in the gas phase and isolated in low-temperature inert matrices. The UV-induced photofragmentation reactions of two of the compounds isolated in cryogenic inert matrices were studied as illustrative cases. The structures of the crystals reported previously in the literature are revisited and discussed also in a comparative basis. Particular emphasis is given to the analysis of the intermolecular interactions in the different crystals, using Hirshfeld surface analysis, the CE-B3LYP energy decomposition model and the HOMA index, and to their correlation with thermodynamic data.

A solid acid catalyst bearing sulphamic acid on sawdust (SA@Sawdust) was designed as a novel heterogeneous catalyst. The structure of prepared catalyst was assessed by various spectroscopic techniques such as FT-IR, field emission scanning electron microscopy and energy dispersive X-ray, thermogravimetric analysis, solid-state CP/MAS C-13-NMR spectroscopy, and CHNS analysis. The efficiency of prepared catalyst was explored for synthesis of diverse 1,8-dioxo-octahydroxanthene derivatives. The mild reaction conditions are found to be more compatible with a wide range of functional groups. The obtained products could be conveniently separated from the reaction mixture by simple filtration, and the catalyst is recovered and reused for next cycle without significant loss in catalytic efficiency. The alluring features of this synthetic route are operational simplicity, shorter reaction time, high conversion, wide substrate scope, easy work-up procedure, and reusability of catalyst.

Solvent-free, atom-efficient, and mechanochemically activated reactions have emerged as synthetic strategy for sustainable chemistry. Herein we report a new mechanochemical approach for the amide coupling of carboxylic acids and amines, mediated by combination of (1-cyano-2-ethoxy-2-oxoethylidenaminooxy)-dimethylaminomorpholinocarbenium hexafluorophosphate (COMU) or N,N,N’,N’-tetramethylchloroformamidinium hexa-fluorophosphate (TCFH) and K2HPO4. The method delivers a range of amides in high yields (70-96%) and fast reaction rates. The reaction protocol is mild, keeps stereochemical integrity of the adjacent to carbonyl stereocenters, and streamlines isolation procedure for solid amide products. Minimal waste is generated due to the absence of bulk solvent. We show that K2HPO4 plays a dual role, acting as a base and a precursor of reactive acyl phosphate species. Amide bonds from hindered carboxylic acids and low-nucleophilic amines can be assembled within 90 minutes by using TCFH in combination with K2HPO4 or N-methylimidazole. The developed mechanochemical liquid-assisted amidation protocols were successfully applied to the challenging couplings of all six carboxylate functions of biotin[6]uril macrocycle with phenylalanine methyl ester, resulting in 80% yield of highly pure hexa-amide-biotin[6]uril. In addition, fast and high-yielding synthesis of peptides and versatile amide compounds can be performed in a safe and environmentally benign manner, as verified by green metrics.
