Carboxylesterase (CES) plays an important role in the hydrolysis metabolism of ester-type drugs and prodrugs. In this study, we investigated the change in the hydrolysis rate of hCE1 by focusing on the steric hindrance of the ester structure and the electron density. For 26 kinds of synthesized indomethacin prodrugs, the hydrolytic rate was measured in the presence of human liver microsomes (HLM), human small intestine microsomes (HIM), hCE1 and hCE2. The synthesized prodrugs were classified into three types: an alkyl ester type that is specifically metabolized by hCE1, a phenyl ester type that is more easily metabolized by hCE1 than by hCE2, and a carbonate ester type that is easily metabolized by both hCE1 and hCE2. The hydrolytic rate of 1-methylpentyl (hexan-2-yl) ester was 10-times lower than that of 4-methylpentyl ester in hCE1 solution. hCE2 was susceptible to electron density of the substrate, and there was a difference in the hydrolysis rate of up to 3.5-times between p-bromophenyl ester and p-acetylphenyl ester. By changing the steric hindrance and electron density of the alkoxy group, the factors that change the hydrolysis rate by CES were elucidated.

Discovered over a century ago, Beckmann rearrangement is still today fully compliant with all the green chemistry principles and consistent with the key aspects of sustainable development. Herein, we report on a sustainable mechanochemical procedure allowing the design of new amide frameworks via an eco-efficient cut-and-paste process of C-C and C-N bonds on the oxime backbone. We combined inexpensive and readily available reagents, such as p-tosyl imidazole (p-Ts-Im) and oxalic acid, to prepare smoothly and in good to high yields a library of structurally different amides, including value-added marketed compounds such as epsilon-caprolactam and the active pharmaceutical ingredient (API) paracetamol. This solvent-free mechanochemical procedure has also been optimized and successfully extended to several ketones serving as oxime precursors.

Though concept of oxygen bridged bimetallic catalyst for organic reaction is not well understood. Herein, we have tried to explain the concept by experimental as well as its support by full DFT study. We report here a competent protocol for dehydrogenative oxidation of benzylic alcohol using an oxygen bridged bimetallic CuMoO4 nano catalyst. Careful demonstration reveals that oxidation is not effective either with mono-metallic Cu (II) or Mo(VI); instead combination of both the metals through the oxygen bridge [Cu-O-Mo] unexpectedly and interestingly catalyzed the reaction efficiently. The new concept is strongly supported by computational DFT study. DFT study reveals dehydrogenative oxidation is preferred at copper centre over molybdenum and aromatic benzyl alcohols are greatly stabilised. Interaction barrier energy of monometallic CuO and MoO3 catalyst is much higher than bimetallic CuMoO4. Hydrogen transfer has larger barrier heights for CuO (31.5 kcal/mol) and MoO3 (40.3 kcal/mol) than bimetallic CuMoO4.

A new class of actinide complexes [(L)An(N{SiMe3}(2))(3)] (An = Th or U) (Th1-Th3 and U1-U3) supported by highly nucleophilic seven-membered N-heterocyclic iminato ligands were synthesized and fully characterized by single-crystal X-ray diffraction. These complexes were successfully exploited as powerful catalysts for the addition of alcohols to carbodiimides to yield the corresponding desirable isourea products at room temperature with short reaction times and excellent yields. Thorough stoichiometric, thermodynamic, and kinetic studies were carried out, allowing us to propose a plausible mechanism for the catalytic reaction.

Noscapine displays weak anticancer efficacy and numerous research efforts have attempted to generate more potent noscapine analogues. These modifications included the replacement of the N-methyl group in the 6 ‘-position with a range of substituents, where N-ethylcarbamoyl substitution was observed to possess enhanced anticancer activity. Herein, we describe advances in this area, namely the synthesis and pharmacological evaluation of a series of N-sulfonyl and N-sulfamoyl noscapine derivatives. A number of these sulfonyl-containing noscapinoids demonstrated improved activities compared to noscapine. ((R)-5-((S)-4,5-Dimethoxy-1,3-dihydroisobenzofuran-1-yl)-4-methoxy-6-((1-methyl-1H-imidazol-4-yl)sulfonyl)-5,6,7,8-tetrahydro[1,3]dioxolo[4,5-g]isoquinoline) (14 q) displayed sub-micromolar activities of 560, 980, 271 and 443 nM against MCF-7, PANC-1, MDA-MB-435 and SK-MEL-5 cells, respectively. This antiproliferative effect was also maintained against drug-resistant NCI/Adr(RES) cells despite high expression of the multidrug efflux pump, P-glycoprotein.

A straightforward synthesis of a library of largely new 3-vinylindoles via a clean dehydrative coupling reaction between ketones and indoles has been developed. Highly stable, non-nucleophilic aryl(2-methylindol-3-yl)methylium salts have been used as efficient Lewis acid catalysts. The advantages of the reaction are the use of equimolar amounts of inexpensive and easily available reagents, the low catalyst amount, high atom efficiency, the production of only one molecule of water as a by-product and the mild reaction conditions. Computational studies of two specific reaction mechanism instances show that both steric and electronic effects heavily influence the nature of the final products, whether a methyl group in position 2 of the indole is present or absent.

Cleavage of C-O bonds in lignin can afford the renewable aryl sources for fine chemicals. However, the high bond energies of these C-O bonds, especially the 4-O-5-type diaryl ether C-O bonds (similar to 314 kJ/mol) make the cleavage very challenging. Here, we report visible-light photoredox-catalyzed C-O bond cleavage of diaryl ethers by an acidolysis with an aryl carboxylic acid and a following one-pot hydrolysis. Two molecules of phenols are obtained from one molecule of diaryl ether at room temperature. The aryl carboxylic acid used for the acidolysis can be recovered. The key to success of the acidolysis is merging visible-light photoredox catalysis using an acridinium photocatalyst and Lewis acid catalysis using Cu (TMHD)(2). Preliminary mechanistic studies indicate that the catalytic cycle occurs via a rare selective electrophilic attack of the generated aryl carboxylic radical on the electron-rich aryl ring of the diphenyl ether. This transformation is applied to a gram-scale reaction and the model of 4-O-5 lignin linkages.

Ce-UiO-66 MOF, namely cerium-organic framework was prepared through a fast and efficient method under ultrasonic radiation. After preparation, it was identified using some different microscopic and spectroscopic techniques such as PXRD, FT-IR, TG/DTA, BET, BJH, and FE-SEM. The catalytic activity of Ce-UiO-66 MOF was checked in aerobic oxidation of methyl arenas, alcohols and styrene derivatives in a sustainable circumstance with no additives. Moreover, its catalytic activity was surveyed influenced by a number of variables in the ultrasonic synthesis method. Some parameters such as solvent, base, temperature, amount of the catalyst and time were also tested to optimize the aerobic oxidation reaction. After the 10th run, the recycled Ce-MOF showed an acceptable efficiency, which proved its high reusability and stability under optimized conditions. Furthermore, the Ce-UiO-66 was investigated structurally by PXRD method which demonstrated the catalyst stability after the aerobic oxidation reaction.

Pyroligneous acid (PA) was obtained by condensation of the vapors produced in the thermal decomposition of culms residues from Guadua angustifolia Kunth (G. angustifolia) cultivated in Colombia, with and without previous preservation treatment with borax salts. Chemical characterization by GC-MS showed that PA extracts has high content of phenolic compounds. Mequinol, isocreosol, 4-ethylphenol, 4-ethyl-2-methoxyphenol, 3,5-dimethoxy-4-hydroxytoluene and 2,6-dimethoxyphenol were the most abundant substances, identified. The total phenolic content (TPC) and DPPH free radical scavenging activity, were investigated. TPC showed a concentration of 1.959 mg GA g(-1) +/- 0.010 and 3.844 mg GA g(-1) +/- 0.027 to PAC and PAS samples. These samples also exhibited high DPPH activity of 70.975%+/- 0.921 and, 16.667%+/- 0.298, respectively. The chemical composition, TPC and DPPH results indicate that the PA extracts obtained from G. angustifolia may be used as a raw material in the food industry as natural preservative, in medicine as alternative to antibiotics and in agriculture as insect repellent and foliar fertilizer.
