Celecoxib containing pyrazole derivatives were synthesized by path aldol condensation of substituted ketone with trifluoroethyl acetate subsequently by cyclization of the formed chalcones with 4-methanesulfonylphenylhydrazine. Here, a one-pot synthesis of celecoxib and substituted analogues have been reported which are nonsteroidal anti-inflammatory drugs for their cyclooxygenase (COX) inhibition, anti-inflammatory activity and ulcerogenic liability. In order to intermediate work-up, a continuous one-pot synthesis has been developed, performing the entire reaction sequence that results in a shorter time with good yield.

The objective of this work is to apply yellow mustard seeds in the enzymatic reduction (biocatalysis) of acetophenone and its derivatives, providing a new biocatalyst for this type of reduction. The reaction parameters were optimized from acetophenone, resulting in 1-phenylethanol, with 68.5% conversion yield and 53% enantiomeric excess (e.e.), analyzed by GC and HPLC, respectively. Reactions to acetophenone and its derivatives were conducted in aqueous medium using buffers pH 6.0 and pH 6.5 in the presence of PVP. A polymer that can act as a protector preventing oxidation of peroxidase enzymes. The results for the derivatives presented low yields (4-18%: substances 5, 7 and 8), moderate (28-40%: substances 3, 4 and 6) and optimum (81%: substance 2) yields, with enantiomeric excesses varying from good to excellent results. Meta-substituted derivatives showed inversion of configuration in the presence of PVP. The biocatalyst was also tested in reactions with other carbonyl compounds, presenting moderate results. In this way, this work offers a new perspective of the application of PVP in biocatalysis reactions and a new biocatalyst for future applications.

Crystals of (2E)-1-(4-nitrophenyl)-3-(2,3,4-trimethoxyphenyl)prop-2-en-1-one (NPTMP) are grown by slow solvent evaporation technique. The compound purity and presence of functional group elements in the material were identified from the spectroscopic techniques (FT-IR and ?H-NMR). The single-phase formation in the bulk powder crystalline sample has been confirmed from powder XRD analysis. The intermolecular interaction and structure-related parameters were obtained and analyzed by utilizing single-crystal XRD data. Using single-crystal XRD data (CIF file), display of the intermolecular interactions and contribution of H center dot center dot center dot H and H center dot center dot center dot O/O center dot center dot center dot H interaction have been obtained. The molecule is mapped over dnorm, de, di, curvedness, shape index, and electrostatic potential by generating the Hirshfeld’s surface of NPTMP molecule. The linear optical absorbance and optical bandgap of the material have been confirmed by UV-VIS-NIR spectroscopic technique. The thermal stability of the crystal NPTMP is obtained from TGA/DTA/DSC techniques. The surface morphology of the crystal is collected from scanning electron microscopy (SEM) and the electronic contribution of hyperpolarizability parameters is obtained from MOPAC 2016 software. The third-order nonlinear optical properties were studied by the Z-scan technique using CW DPSS laser operating at 532 nm wavelength. The molecule exhibits a comparatively moderate optical limiting response due to reverse saturable absorption (RSA).

On water catalytic aldol reaction catalyzed by polyetheramine (D230) has been developed for easy access to 3-substituted 3-hydroxyindolin-2-ones through the reaction between various substituted isatins and acetophenones/cyclic ketones in high yields under room temperature. Systematic mechanism investigation uncovers the secret for the on water catalytic aldol reaction: comparison of the heterogeneous and homogeneous reaction circumstances with yields of 95 and 20%, respectively, indicates the on-water reaction dominating; interfacial hydrogen bonding between isatin with H2O is tested based on the downfield shift of the C2 and C3’s C-13 NMR signals when water was added to the CDCl3 solution of isatin; Lewis base polyetheramine D230 catalyzes the aldol reaction via the enamine mechanism verified by in situ NMR and ESI-MS analysis.

A brick pavement, tramped by humans, is exposed to atmospheric elements, thus allowing cyanobacteria and algae to colonise. In this article, we report on the factors that contribute to the slipperiness of a brick pavement at the University of Venda in the Limpopo province of the South Africa. Samples were collected from brick surfaces either colonised by green algae (treated) or not (control). The samples were acid-digested and analysed for metals by Inductively Coupled Plasma Mass Spectrometry (ICP MS) in parts per billion (ppb). The treated bricks, with green algae, had average high metal contents (ppb): Al 9456.02, Ti 731.23, V 46.44, Cr 78.85, Mn 862.93, Fe 16295.18, Co 23.57, Ni 59.36, Cu 66.31, Zn 160.57, As 7.92, Se 10.45, Mo 6.74, Cd 5.19, Sn 4.65, Sb 2.31 and Pb 19.51. In contrast, control bricks had a low average of metal content (ppb) as follows: Al 2.99, Ti 0.28, V 4.04, Cr 1.42, Mn 4.29, Fe 20.89, Co 0.36, Ni 2.74, Cu 5.64, Zn 4.21, As 0.56, Se <3.00, Mo 0.88, Cd 0.01, Sn 1.05, Sb 0.04 and Pb 0.04. Other factors that promote algae colonisation include high solar radiation, neutral pH, nutrients, low electrical conductivity and total dissolved solids. The algae colonisation of brick pavement results in an unaesthetic sighting and a slippery surface that is hazardous to humans.

The influence of previously synthesized 2-aroyl-1,1,3,3-tetracyanoprop-2-en-1-ides on the growth of conditionally normal and tumor cells was studied in continuation of a search for new anticancer drugs. Cytotoxicities of the compounds were studied with respect to human tumor cell lines from the ATCC. All compounds were ineffective against melanoma and lung and ovary cancer cell lines and exhibited moderate activity in the other cases. The tested compounds exhibited highly selective effects because they were safe for conditionally normal skin fibroblasts.

The aim of the present study is to design and synthesis of new pyrazole-triazolopyrimidine hybrids as potent alpha-glucosidase inhibitors. The target compounds 4a-n were synthesized by one-pot multicomponent approach with good yields and were characterized by various spectroscopic techniques and finally by single crystal X-ray diffraction method (4j). All the newly-synthesized derivatives have been screened for their alpha-glucosidase enzyme inhibition activity and acarbose taken as a standard drug. Among all the tested compounds, 4h has displayed excellent alpha-glucosidase enzyme inhibition activity with IC50 value 12.45 mu M to the standard drug acarbose (IC50: 12.68 mu M). Similarly, the compounds 4f and 4l have exhibited potent activity with IC50 values 14.47 mu M and 17.27 mu M respectively. Structure-activity relationship (SAR) studies of all the title compounds were established. The mode of binding interactions between the alpha-glucosidase enzyme and the compounds were studied. The drug-likeness properties (Lipinski parameters and in silico ADME properties) have predicted for the target compounds. The alpha-glucosidase inhibition, molecular docking and drug-likeness properties of the compounds 4h, 4f and 4l were suggested that these are promising hits for anti-diabetic activity.

The rearrangement of ene-aldimines is a useful reaction for affording homoallylic amines. Despite their utilities in synthetic chemistry, the rearrangement for accessing homoallylic amines substituted at the 2-position remains elusive. In this study, the Bronsted acid-initiated formal [1,3]-rearrangement of ene-aldimines was developed to synthesize 2,4,4-substituted homoallylic amines that were otherwise inaccessible previously. Our study reveals an intermolecular pathway in which the rearrangement proceeds via a protonation-mediated 2-azaallenium cation.

The reaction of LH [L = {(ArNH)(ArN)-C=N-C=(NAr)(NHAr)}; Ar =2,6-Et-2-C6H3] with a commercially available alane amine adduct (H3Al center dot NMe2Et) in toluene resulted in the formation of a conjugated bis-guanidinate (CBG)-supported aluminum dihydride complex, i.e., LAIH(2) (1), in good yield. The new complex has been thoroughly characterized by multinuclear magnetic resonance, IR, mass, and elemental analyses, including single-crystal structural studies. Further, we have demonstrated the aluminum-catalyzed hydroboration of a variety of nitriles and alkynes. Moreover, aluminum-catalyzed hydroboration is expanded to more challenging substrates such as alkene, pyridine, imine, carbodiimide, and isocyanides. More importantly, we have shown that the aluminum dihydride catalyzed both intra- and intermolecular chemoselective hydroboration of nitriles and alkynes over other reducible functionalities for the first time.
