Hydroboration of carbonyl compounds is an important transformation in organic chemistry, and a growing interest in catalysis has focused on abundant and nontoxic base metals. Herein we describe an efficient salen manganese catalyst for the hydroboration of a broad range of carbonyl compounds with pinacolborane. The catalytic reactions proceeded rapidly (>99% conversion in <5 min) at room temperature with very low catalyst loadings. High turnover frequency (up to 5700 h(-1)) was observed under these conditions. Several synthetically important functional groups were tolerated, and chemoselective hydroboration of aldehydes over ketones was achieved. The H/D kinetic isotopic effect of borane was determined to be 2.3. The Hammett correlation plot of a series of para-substituted acetophenone substrates, p-X-C6H6COCH3 (X = H, Me, OMe, NO2, Cl, Br, and CF3) yielded a positive slope of rho = +0.99. The crossover products were detected in the competition reaction of catecholborane and deuterated pinacolborane with acetophenone. The findings indicated a potential borane-mediated pathway that could account for the observation of the crossover products.

A divergent strategy for the facile preparation of various enantioenriched phenylthio-substituted lactones was developed based on Lewis base/Bronsted acid co-catalyzed thiolation of homoallylic acids. The acid-controlled regiodivergent cyclization (6-endo vs. 5-exo) and acid-mediated stereoselective rearrangement of phenylthio-substituted lactones were explored. Experimental and computational studies were performed to clarify the origins of the regioselectivity and enantioselectivity. The calculation results suggest that C-O and C-S bond formation might occur simultaneously, without formation of a commonly supposed catalyst-coordinated thiiranium ion intermediate and the potential pi-pi stacking between substrate and SPh as an important factor in the enantio-determining step. Finally, this methodology was applied in the rapid syntheses of the bioactive natural products (+)-ricciocarpin A and (R)-dodecan-4-olide.

The condensation of 4H-1,2,4-triazol-3-amine with ortho esters derived from acetic, propionic, and benzoic acids gave the corresponding N-(4H-1,2,4-triazol-3-yl) carboximidates which were treated with cyanamide, carbon disulfide, and sodium thiocyanate to afford 7-substituted [1,2,4]triazolo[4,3-a][1,3,5]triazin-5-amines, [1,2,4]triazolo[4,3-c][1,3,5]thiadiazine-5-thiones, and [1,2,4]triazolo[4,3-c][1,3,5]thiadiazin-5-imines, respectively.

Inspired by the synergistic effects of hetero-aromatic scaffolds on curcumin, a novel array of pyrazoline substituted curcumin analogs was designed. Multi-scale computational studies were carried out to target the proposed analogs on human kinase beta (IKK-beta), a potential anti-cancer target. In molecular docking analysis, all the eleven molecules were observed to bind the target site and 4-bromo-4′-chloro analog displayed three hydrogen bond interactions with a docking score of -11.534 kcal/mol higher than parent molecule, curcumin (docking score = -7.12 kcal/mol) as the propellant shaped of analogs aided in proper binding with Kinase Domain binding pocket. The molecular dynamics and simulations studies revealed that the stable complexes of lead molecule were developed as the minimal deviations per residue of protein found within the range of 0.11 to 0.92 angstrom. The proposed compounds were synthesized, characterized and biologically evaluated against human cervical cancer cell line, HeLa, using standard MTT cell assay. Bio-evaluation studies exhibited superior cytotoxic profile for many analogs as Chloro bromo analog with IC50 value (8.7 mu g/mL) exhibited fivefolds improvement in the potency in comparison to curcumin (IC50 = 42.4 mu g/mL) but was less potent than the standard drug, paclitaxel (IC50 = 0.008 mu g/mL). The apoptotic effect was evaluated in the terms of caspase-3 enzyme cleavage and exhibited 70.5% of apoptosis significantly (p < 0.05) higher than 19.9% induced by curcumin. In short, 4-bromo-4'-chloro analog was the potent cytotoxic agent in this structural class and must be evaluated further under a set of stringent parameters for transforming in to a clinically viable therapeutic molecule.

The chalcone derivatives 3a-d reacted with either malononitrile or ethyl cyanoacetate in ethanol in the presence of catalytic amount of ammonium acetate in an oil bath at 120 degrees C to give the Knowevenagel condensation products 5a-h. The latter compounds reacted with hydrazine hydrate and afforded the 4H-pyrazole derivatives 7a-h, respectively. The reaction of compounds 7a-h with ethyl cyanoacetate in dimethylformamide under refluxing condition afforded the cyanoacetamido derivatives 8a-h, respectively. When compounds 8a-h reacted with elemental sulfur and either of malononitrile or ethyl cyanoacetate in ethanol containing triethylamine, the thiophene derivatives 9a-h and 10a-h, respectively, were obtained. The structure of the newly synthesized compounds was established by the analytical and spectral data. All the newly synthesized compounds were evaluated against the six cancer cell lines: A549, HT-29, MKN-45, U87MG, and SMMC-7721 and H460. Compounds 3c, 5h, 7g, 7h, 8f, 9e, 9g, and 10g were selected to examine their Pim-1 kinase inhibition activity as these compounds showed high inhibition toward the c-Met kinase and the tested cancer cell lines. Furthermore, compounds 3b, 3c, 5g, 5h, 7f, 7g, 7h, 8e, 8f, 8g, 8h, 9e, 9f, 9g, 9h, 10g and 10h were selected to be tested for pan-assay interference compounds analysis (PAINS).

A method is developed for in situ generation of 1,3-dioxan-5-one derivatives 2. These compounds are simple precursors for accessing carbohydrate structures and previously had to be produced via stepwise procedures using excessive amounts of reagents. In the present work, three different derivatives of 2 were synthesized via the reaction of trialkoxyalkanes with dihydroxyacetone dimer 1 in the presence of acetic acid as the catalyst. In the same pot, derivatives of 2 were reacted with aromatic aldehydes and 30 mol% of pyrrolidine to obtain high yields of the respective bischalcones 3 within short time periods.

A group of novel 1,4-bis(3,5-dialkyl-4H-1,2,4-triazol-4-yl)bencene and 5-aryltriaz- 1-en-1-yl-1-phenyl-1H-pyrazole-4-carbonitrile derivatives have been successfully synthesized and characterized by spectroscopic analyses. The triazenes were obtained in moderate yield by a coupling reaction between 5-aminopyrazol-4-carbonitrile and aryl diazonium chlorides, and their structures were confirmed by detecting the CN functional group in both IR and C-13 NMR spectra. Conversely, the novel 1,4-bis(3,5-dialkyl-4H-1,2,4-triazol-4-yl)benzene derivatives were obtained using a previously unreported and facile pathway starting with p-phenylenediamine with selected triethyl orthoalkylates and then hydrazine monohydrate, followed by refluxing in triethyl orthoalkylates. The structure of the methyl derivative was confirmed by X-ray analysis. The synthesized compounds were tested and evaluated as antimicrobial agents.

Various phytochemicals have been reported to protect against oxidative stress. However, the mechanism underlying has not been systematically evaluated, which limited their application in disease treatment. Nuclear factor erythroid 2 – related factor 2 (Nrf2), a central transcription factor in oxidative stress response related to numerous diseases, is activated after dissociating from the cytoskeleton – anchored Kelch – like ECH – associated protein 1 (Keap1). The Keap1-Nrf2 protein-protein interaction has become an important drug target. This study was designed to clarify whether antioxidantive phytochemicals inhibit the Keap1-Nrf2 protein-protein interaction and activate the Nrf2-ARE signaling pathway efficiently. Molecular docking and 3D – QSAR were applied to evaluate the interaction effects between 178 antioxidant phytochemicals and the Nrf2 binding site in Keap1. The Nrf2 activation effect was tested on a H2O2 – induced oxidative – injured cell model. Results showed that the 178 phytochemicals could be divided into high – , medium – , and low – total -score groups depending on their binding affinity with Keap1, and the high total – score group consisted of 24 compounds with abundant oxygen or glycosides. Meanwhile, these compounds could bind with key amino acids in the structure of the Keap1 – Nrf2 interface. Compounds from high – total – score group show effective activation effects on Nrf2. In conclusion, phytochemicals showed high binding affinity with Keapi are promising new Nrf2 activators.
