A library of 1,2,4-oxadiazole functionalized quinoline derivatives (13a-j) were synthesized and their structures were confirmed by H-1 NMR, (CNMR)-C-13 and Mass Spectral analysis. Further, these compounds were evaluated for their anticancer activity against four human cancer cell lines, namely MCF-7 (breast), A549 (lung), DU-145 (prostate) and MDA MB-231 (breast) using Etoposide as the positive control. Most of these derivatives exhibited more potent activity towards the four cancer cell lines compared to Etoposide. Amongst all the compounds tested, compounds 13b, 13c, 13h, 13i and 13j exhibited promising activity. Further of these compounds 13b, 13i and 13j exhibited excellent activity, when compared with Etoposide.

The PYR/PYL/RCAR protein families have recently emerged as receptors of the phytohormone abscisic acid (ABA, 1), which regulates plant responses to environmental stress. These families have multiple members with different physiological actions, and so selective agonists or antagonists are needed both as tools to elucidate functional differences and as lead compounds for agrochemicals. We previously identified RK460 (rac-3 a) as a PYR1-selective antagonist, and showed that it possesses five stereocenters on a 6,5-cis-bicyclo skeleton. Here, we synthesized all the stereoisomers of RK460 and evaluated their activity towards a panel of receptors. Relative stereochemistry as well as absolute stereochemistry was important for selective action.

An operationally simple isothiourea-catalysed acylative kinetic resolution of unprotected 1,1 ‘-biaryl-2,2 ‘-diol derivatives has been developed to allow access to axially chiral compounds in highly enantioenriched form (s values up to 190). Investigation of the reaction scope and limitations provided three key observations: i) the diol motif of the substrate was essential for good conversion and high s values; ii) the use of an alpha,alpha-disubstituted mixed anhydride (2,2-diphenylacetic pivalic anhydride) was critical to minimize diacylation and give high selectivity; iii) the presence of substituents in the 3,3 ‘-positions of the diol hindered effective acylation. This final observation was exploited for the highly regioselective acylative kinetic resolution of unsymmetrical biaryl diol substrates bearing a single 3-substituent. Based on the key observations identified, acylation transition state models have been proposed to explain the atropselectivity of this kinetic resolution.

Supercritical fluid chromatography is becoming more prevalent, particularly in industry. This is due to the inexpensive, and more importantly, environmentally benign carbon dioxide that is used as the major component of the mobile phase. Water is minimally miscible with carbon dioxide at temperatures and pressures commonly used in SFC. However, the introduction of a polar alcohol modifier component increases the solubility of water in carbon dioxide. Previously, the addition of small amounts of water in the mobile phase was shown to provide significant gains in efficiency in chiral supercritical fluid chromatography, especially with polar stationary phases. In this work, we report the effect of the addition of small amounts of water on efficiency and retention factor with four different SFC stationary phases used for achiral analysis namely FructoShell-N (native cyclofructan-6), SilicaShell (bare silica), PoroShell 120 EC C18 (octadecyl silica) and Xselect C18 SB. This is the first reported use of FructoShell-N, a cyclofructan derivatized phase for SFC applications. We devised a predictive test to determine which analytes show an increase in efficiency using their known chemical constants (logK(ow), pK(a), PSA and H-sum). We also use discriminant analysis to elucidate the most important analyte parameters that contribute to water enhanced efficiency gains. (C) 2020 Elsevier B.V. All rights reserved.

A new series of Pyrazolo[3,4-d]pyrimidine containing amide derivatives (8 a-l) were designed, synthesized, and evaluated for their in vitro alpha-amylase inhibitory activity. The IC50 values of the target compounds ranged from 1.60 +/- 0.48 to 2.04 +/- 1.20 mu M as compared to the standard acarbose 1.73 +/- 0.05 mu M. All the Pyrazolo[3,4-d]pyrimidine amide derivatives displayed good inhibitory activities, while seven analogs (8 d, 8 f, 8 g, 8 h, 8 i, 8 j and 8 k) exhibited more or less equipotent activity with IC50 values 1.77 +/- 2.84, 1.65 +/- 0.45, 1.66 +/- 2.24, 1.73 +/- 0.37, 1.60 +/- 0.48, 1.75 +/- 0.36 and 1.64 +/- 0.03 mu M respectively. Further, the most potent alpha-amylase inhibitors 8 d and 8 k were also screened for their in vivo antidiabetic activity against alloxan induced diabetic rat model at the dose of 25 and 50 mg/kg. Oral administration of these tested compounds significantly reduced the fasting blood glucose levels in dose dependent manner. The hypoglycemic effects of these compounds were more evident at 3 h and 5 h after administration of tested compounds which was similar to the effect displayed by the positive control. In addition, the binding energies calculated from the docking studies with the alpha-amylase enzyme (PDB ID: 1HNY) and biological activities indicate that the compounds containing nitro moiety on the phenyl group contributed significantly towards the antidiabetic activity.

Fluorescent silicon nanoparticles (SiNPs) displayed different emission wavelengths have been synthesized, but it has not been reported that the preparation of wavelength controllable SiNPs by adjusting the nitrogen content of reducing agents. In this paper, the wavelength-controlled fluorescent SiNPs were prepared by selecting the dopamine (DA) with nitrogen content between catechol and 2-aminophenol as the reducing agent and N-[3-(trimethoxysilyl) propyl]-ethylenediamine (DAMO) as the silicon source via one-step hydrothermal method. The emission wavelength of the prepared SiNPs was in direct proportion to the nitrogen content in the reducing agent. To the best of our knowledge, this is the first time for exploring the nitrogen content in reducing agents could affect the optical properties of SiNPs so far. In addition, the obtained SiNPs could be applied to determinate 2-nitrophenol (2-NP). Based on the combination action of inner filter effect (IFE) and static quenching effect (SQE) mechanism, a wide linear range was obtained from 0.1 to 500 mu M, and the limit of detection was 0.029 mu M for 2-NP, which was comparable to or even lower than some previous reports. This SiNPs probe was also successfully employed for sensing of 2-NP in industrial effluent with satisfactory results (98.6%-103.4%).

An asymmetric [3 + 2] formal cycloaddition reaction between oxindole alpha-keto esters and enals has been developed. This alpha,gamma-regioselective reaction afforded multifunctional carbocyclic oxindoles via dienamine-enamine cascade reaction followed by isomerization. Furthermore, a highly enantioselective Diels-Alder reaction was demonstrated between 2,4-dienals and oxindole alpha-keto esters via trienamine intermediates. Chiral secondary amine catalyzed the both reactions under mild conditions and the cyclized products were isolated in moderate to good yields with good diastereoselectivities (>20:1 dr) and enantioselectivities (up to 99 %).

Application In Synthesis of 4-Nitrobenzoic acid. Qureshi, ZS; Jaseer, EA in [Qureshi, Ziyauddin S.; Jaseer, E. A.] King Fahd Univ Petr & Minerals, Ctr Refining & Petrochem, POB 5040, Dhahran 31261, Saudi Arabia published Effective and selective direct aminoformylation of nitroarenes utilizing palladium nanoparticles assisted by fibrous-structured silica nanospheres in 2020, Cited 67.

Palladium nanoparticles (similar to 1-3 nm, 0.4 wt% Pd) were uniformly distributed over the surface of fibrous silica nanospheres (KCC-1) modified via aminopropyltriethoxysilane using a fast and cost-effective palladium (II) chloride reduction process. The Pd nanoparticles (Pd NPs) distribution over the ensuing catalyst Pd/KCC-1-NH2 showed much more uniform distribution, and smaller size compared with the tedious hydrothermal reduction method. The morphological, chemical, and size analyses of Pd/KCC-1-NH2 by BET, UV-Vis spectra, XRD, HR-TEM, EDS and XPS analysis revealed that the succeeding material consist of a distinct fibrous silica nanospheres support adorn with Pd NPs. The resultant nanocatalyst was tested for the one-step reductive aminoformylation of aromatic nitro compounds using formic acid. A wide range of substituted nitroarenes including electron withdrawing, releasing, sterically hindered and multifunctional groups have been converted to corresponding aryl formamide in quantitative yields (yields up to 98%) at moderate temperature (70 degrees C). Optimization study has proved that the 6 equivalent of formic acid is required and toluene was found to be the better solvent. The established practice is beneficial due to the use of formic acid as H-2 source and formylating agent, easiness in handling of the catalyst and simple workup procedure with efficient catalyst reusability.
