Catalyst-free photoinduced processes in aqueous medium represent significant advancement toward development of green and sustainable pathways in organic synthesis. tert-Butyl hydroperoxide (TBHP) is a widely used oxidant in organic reactions, where the decomposition of TBHP into its radicals by metal catalysts or other reagents is a key factor for efficient catalytic outcome. Herein, we report a simple and environmentally friendly visible light-promoted synthetic pathway for the synthesis of N-heterocyclic moieties, such as quinazolinones and quinoxalines, in the presence of TBHP as an oxidizing agent in aqueous medium that requires no catalysts/photocatalysts. The enhanced rate of decomposition to generate free radicals from TBHP upon visible light irradiation is the driving force for the domino reaction.

Although carbon radicals generated from a variety of alcohol derivatives have proven valuable in coupling and addition reactions, the direct use of alcohols as synthetically useful radical sources is less known. In this report, benzylic alcohols are shown to be effective radical precursors for addition reactions to alkenes when treated with triphenylphosphine or piperidine with the catalyst ReIO2(PPh3)(2) (I).

Nitrogen (N)-doped nanocarbons (NDN) as metal-free catalysts have elicited considerable attention toward selective oxidation of alcohols with easily oxidizable groups to aldehydes in the past few years. However, finding a new NDN catalytic material that can meet the requirement of the feasibility on the aerobic catalytics for other complicated alcohols is a big challenge. The real active sites and the corresponding mechanisms on NDN are still unambiguous because of inevitable coexistence of diverse edge sites and N species based on recently reported doping methods. Here, four NDN catalysts with enriched pyridinic N species and without any graphitic N species are simply fabricated via a chemical-vapor-deposition-like method. The results of X-ray photoelectron spectroscopy and X-ray absorption near-edge structure spectra suggest that the dominating N species on NDN are pyridinic N. It is demonstrated that NDN catalysts perform impressive reactivity for aerobic oxidation of complicated alcohols at an atmospheric pressure. Eleven kinds of aromatic molecules with single N species and tunable pi conjugation systems are used as model catalysts to experimentally identify the actual role of each N species at a real molecular level. It is suggested that pyridinic N species play an unexpected role in catalytic reactions. Neighboring carbon atoms in pyridinic N species are responsible for facilitating the rate-determining step process clarified by kinetic isotope effects, in situ nuclear magnetic resonance, in situ attenuated total reflectance infrared, and theoretical calculation. Moreover, NDN catalysts exhibit a good catalytic feasibility on the synthesis of important natural products (e.g., intermediates of vitamin E and K3) from phenol oxidation.

Intermediates in aromatic amino acid biosynthesis can serve as substrates for the synthesis of bioactive compounds. In this study we used two intermediates in the shikimate pathway of Escherichia coli, chorismate and anthranilate, to synthesize three bioactive compounds: 4-hydroxycoumarin (4-HC), 2,4-dihydroxyquinoline (DHQ), and 4-hydroxy-1-methyl-2(1H)-quinolone (NMQ). We introduced genes for the synthesis of salicylic acid from chorismate to supply the substrate for 4-HC and the gene encoding N-methyltransferase for the synthesis of N-methylanthranilate from anthranilate. Polyketide synthases and coenzyme (Co)A ligases were tested to determine the optimal combination of genes for the synthesis of each compound. We also tested several constructs and identified the best one for increasing levels of endogenous substrates for chorismate, anthranilate, and malonyl-CoA. With the use of these strategies, 255.4 mg/L 4-HC, 753.7 mg/L DHQ, and 17.5 mg/L NMQwere synthesized. This work provides a basis for the synthesis of diverse coumarin and quinoline derivatives with potential medical applications.

Novel and efficient method for the synthesis of a series of beta,gamma-unsaturated-alpha-ketoesters under mild conditions was developed. This one-step protocol was achieved by the reaction of electron-rich aromatic aldehydes and pyruvates in the presence of 10 mol% of molecular iodine in solvent-free condition at 80 degrees C temperature. A wide variety of substrates bearing electron releasing groups on aromatic ring were well tolerated and delivered corresponding beta,gamma-unsaturated-alpha-ketoesters in moderate to good yields. These beta,gamma-unsaturated-alpha-ketoesters have been further utilized in the synthesis of 4,5-dihydropyrazole derivatives. [GRAPHICS] .

The Pot, Atom, and Step Economy (PASE) approach is based on the Pot economy principle and unites it with the Atom and Step Economy strategies; it ensures high efficiency, simplicity and low waste formation. The PASE approach is widely used in multicomponent chemistry. This approach was adopted for the synthesis of previously unknown hydroxyquinolinone substituted chromeno[2,3-b]pyridines via reaction of salicylaldehydes, malononitrile dimer and hydroxyquinolinone. It was shown that an ethanol-pyridine combination is more beneficial than other inorganic or organic catalysts. Quantum chemical studies showed that chromeno[2,3-b]pyridines has potential for corrosion inhibition. Real time H-1 NMR monitoring was used for the investigation of reaction mechanism and 2-((2H-chromen-3-yl)methylene)malononitrile was defined as a key intermediate in the reaction.

We report a synthetic route toward a family of functional COS/H2S-releasing N-substituted N-thiocarboxyanhydrides (NTAs) with functionalities to accommodate popular conjugation reactions, including olefin cross metathesis, thiol-ene, and copper-catalyzed azide alkyne cycloaddition. The N-substituted NTAs were attached to small molecules, polymers, and a protein to synthesize novel H2S donors convergently. All conjugates showed sustained H2S release kinetics.

Naturally derived drugs and plant-based products are attractive commodities that are being explored for cancer treatment. This in vitro study aimed to investigate the role of Hypericum triquetrifolium (50% ethanol: 50% water) extract (HTE) treatment on apoptosis, cell cycle modulation, and cell cycle arrest in human colon cancer cell line (HCT-116). HTE induced cell death via an apoptotic process, as assayed by an Annexin V-Cy3 assay. Exposing HCT-116 cells to 0.064, 0.125, 0.25, and 0.5 mg/mL of HTE for 24 h led to 50 +/- 9%, 71.6 +/- 8%, 85 +/- 5%, and 96 +/- 1.5% apoptotic cells, respectively. HCT-116 cells treated with 0.25 and 0.5 mg/mL HTE for 3 h resulted in 38.9 +/- 1.5% and 57.2 +/- 3% cleavage of caspase-3-specific substrate, respectively. RT-PCR analysis revealed that the HTE extract had no effect on mRNA levels of Apaf-1 and NOXA. Moreover, the addition of 0.125 mg/mL and 0.25 mg/mL HTE for 24 h was clearly shown to attenuate the cell cycle progression machinery in HCT-116 cells. GC/MS analysis of the extract identified 21 phytochemicals that are known as apoptosis inducers and cell cycle arrest agents. All the compounds detected are novel in H. triquetrifolium. These results suggest that HTE-induced apoptosis of human colon cells is mediated primarily through the caspase-dependent pathway. Thus, HTE appears to be a potent therapeutic agent for colon cancer treatment.

The aim of this study was to develop a microemulsion (ME) formulation containing an association of itraconazole (ITC) and clotrimazole (CLT) as a transdermal delivery system for the treatment of sporotrichosis. Pseudoternary phase diagrams were constructed to optimize the ME formulation. The ME formulation selected contained 1% (w/w) ITC and 1% (w/w) CLT and was composed of 23.07% Tween (R) 60 (surfactant), 23.07% propylene glycol (cosurfactant/cosolvent), 30.77% benzyl alcohol (oil), and 21.09% water. The ITC/CLT-loaded ME (ITC/ CLT-ME) had a droplet size value of 217 +/- 0.9 nm, with a poly-dispersity index of 0.5 +/- 0.1. Permeation experiments on pig ear skin were conducted for ITC/CLT-ME, and the results indicated that the drug permeation performance was influenced by CLT, indicating that CLT acts as a promoter enhancer. In the in vitro antifungal activity assay using Sporothrix brasiliensis yeast, the inhibition halo produced by ITC/CLT-ME exhibited a mean diameter of 43.67 +/- 2.31 mm. The ITC/CLT-ME formulation did not cause skin irritation in mice. The results suggest that ITC/CLT-ME is a promising tool for the transdermal treatment of sporotrichosis.
