Herein, we describe novel iron-catalyzed transfer hydrogenation between alcohols and 1-(2-nitrophenyl)pyrroles for the synthesis of pyrrolo[1,2-alpha]quinoxalines. The tricarbonyl (eta(4)-cyclopentadienone) iron complex catalyzed the oxidation of alcohols and the reduction of nitroarenes, and the corresponding aldehydes and aniline were generated in situ. The resulting Pictet-Spengler-type annulation/oxidation completed the quinoxaline structure formation. The protocol tolerated various kinds of functional groups and provided 29 samples of 4-substituted pyrrolo[1,2-alpha]quinoxalines. The developed method was also applied for the synthesis of additional polyheterocycles.

We have synthesized and characterized two small libraries of 2-OMe or 2-NO2-benzene analogues 2a-i and 3a-i containing a wide variety of leaving groups. Irradiation of these compounds at 350 nm generated benzyl radicals that were spontaneously oxidized to benzyl cations directly producing DNA interstrand cross-links (ICLs). Compounds with a 2-methoxy substituent showed a faster cross-linking reaction rate and higher ICL efficiency than the corresponding 2-nitro analogues. Apart from the aromatic substituent, the benzylic leaving groups greatly affected DNA cross-linking efficiency. Higher ICL yields were observed for compounds with OCH3 (3b), OCH2Ph (3d), or Ph3P+ (3i) as leaving groups than those containing OAc (3a), NMe2 (3e), morpholine (3f), OCH2CH=CH2 (3c), SPh (3g), or SePh (3h). The heat stability study of the isolated ICL products indicated that dGs were the preferred alkylation sites in DNA for the benzyl cations produced from 2a-i, 3c, and 3e-i while 3a (L = OAc), 3b (L = OMe), and 3d (L = OCH2Ph) showed a similar photoreactivity toward dGs and dAs. Although the photogenerated benzyl cations alkylated dG, dC, and dA, ICL assay with variation of DNA sequences showed that the ICL reaction occurred with opposing dG/dC but not with staggered dA/dA.

In this work, two novel series of indole-thiosemicarbazone derivatives were designed, synthesized, and evaluated for their cytotoxic activity against MCF-7, A-549, and Hep-G2cell lines in comparison to etoposide and colchicine as the reference drugs. Generally, the synthesized compounds showed better cytotoxicity towards A-549 and Hep-G2 than MCF-7. Among them, (2E)-2-{[2-(4-chlorophenyl)-1H-indol-3-yl]methylidene}-N-(4-methoxyphenyl)hydrazinecarbothioamide (8l) was found to be the most potent compound against A-549 and Hep-G2, at least three times more potent than etoposide. The morphological analysis by the acridine orange/ethidium bromide double staining test and flow cytometry analysis indicated that compound 8l induced apoptosis in A-549 cells. Moreover, molecular docking methodology was exploited to elucidate the details of molecular interactions of the studied compounds with putative targets.

Human Immunodeficiency Virus (HIV) damages the immune system and leads to the life-threatening acquired immunodeficiency syndrome (AIDS). Despite the advances in the field of antiretroviral treatment, HIV remains a major public health challenge. Nucleosides represent a prominent chemotherapeutic class for treating viruses, however their cellular uptake, kinase-mediated activation and catabolism are limiting factors. Herein, we report the synthesis and in vitro evaluation of stavudine (d4T) ProTides containing polyfluorinated aryl groups against two strains; HIV-1 (IIIB) and HIV-2 (ROD). ProTide 5d containing a meta-substituted pentafluorosulfanyl (3-SF5) aryl group showed superior antiviral activity over the parent d4T and the nonfluorinated analogue 5a. ProTide 5d has low nano-molar antiviral activity; (IC50=30 nM, HIV-1) and (IC50=36 nM, HIV-2) which is over tenfold more potent than d4T. Interestingly, ProTide 5d showed a significantly high selectivity indices with SI=1753 (HIV-1) and 1461 (HIV-2) which is more than twice that of the d4T. All ProTides were screened in wild type as well as thymidine kinase deficient (TK-) cells. Enzymatic activation of ProTide 5d using carboxypeptidase Y enzyme and monitored using both P-31 and F-19 NMR is presented.

The resolution of samples containing unknown compounds of different nature, or without standards available, as is the case of chromatographic fingerprints, is still a challenge. Possibly, the most problematic aspect that prevents systematic method development is finding models that describe without bias the retention behaviour of the compounds in the samples. In this work, the use of global models (able to describe the whole sample) is proposed as an alternative to the use of individual models for each solute. Global models contain parameters that are specific for each solute, while other parameters -related to the column and solvent- are common for all solutes. A special regression procedure is presented for the construction of global models, which are applied to predict highly complex chromatograms, such as chromatographic fingerprints, for diverse experimental conditions in isocratic and gradient elution. Another interesting application is the prediction of molecular properties, such as log P-o/w from the specific solute parameters of the global models. The examined adapted models are based on the equations proposed by Snyder, Schoenmakers, Neue and Kuss, Jandera, and Bosch Roses to describe the retention. In all cases, the predictive capability was very satisfactory. Two cases of study were considered: chromatograms of camomile extracts analysed using acetonitrile gradients, and a set of 145 known compounds in a wide range of structures and functionalities, eluted isocratically with acetonitrile/water mobile phases.

To overcome the limitation of traditional photoluminescent materials, a cost-effective photoluminescence polymer was synthesized by a simple and one-step technique using benzyl alcohol as the starting material and aqueous sulfuric acid as the catalyst. The synthesized photoluminescent polymer showed photoluminescence properties independent of the excitation wavelength together with high thermal stability and excellent mechanical properties. The synthesized photoluminescent polymer was incorporated into different polymers viz. thermoplastic as well as thermoset polymers by melt and solution processes, respectively, to achieve photoluminescent polymer blends. The thermal, mechanical, and photoluminescent properties of the fabricated blends were improved or remained almost the same with the photoluminescence polymer contents, strongly proving that the photoluminescent polymer was well dispersed in the polymeric matrix. The potential applications of the photoluminescence polymer blends were investigated for 3D printing and a fluorescent ink. The study paves a way for the development of photoluminescent materials for various applications.

Molecular oxygen is the most important green-oxidant due to its excellent properties. However, the effective utilization of molecular oxygen remains a major challenge in modern chemistry. Herein, we report the development a rapid, green and efficient microwave-assisted protocol for the air oxidation of boronic acids to phenols and alcohols under transition metal-free conditions. In the presence of KOH and DMSO, high yields of the expected phenols and alcohol were obtained with microwave-assistance, and a variety of functional groups were tolerated in this procedure. Notably, this transition metal-free method represents a breakthrough in both organic synthesis and green chemistry for the oxidative hydroxylation of boronic acids to phenols and alcohols.

The essential oil of wintergreen, which is extracted by steam distillation from Gaultheria genus leaves, is mainly used in aromatherapy. However, due to its adulteration easiness with synthetic material, it is necessary to control samples naturalness with accuracy. The purpose of this work was to develop a methodology to authenticate the essential oil of wintergreen. Wintergreen essential oil is composed of more than 99% methyl salicylate. This aromatic ester can be easily synthesized and used to adulterate wintergreen essential oil. Authentic wintergreen essential oil can be distinguished from adulterated oils by examining their compositions. The detection of methyl salicylate synthetic marker compounds (methyl 4-hydroxybenzoate, dimethyl 4-hydroxyisophthalate or dimethyl 2-hydroxyisophthalate) or the absence of several naturally occurring minor secondary metabolites (ethyl salicylate and vitispirane) contribute to the authentication. Isotopic values of bulk wintergreen essential oil have also been determined using an isotope ratio mass spectrometer (IRMS): the delta C-13 values of authentic samples range from -36.78 to -33.36 parts per thousand, the delta H-2 values range from -173 to -115 parts per thousand and the delta O-18 values range from -1.3 to 5.7 parts per thousand. However, these analytical methods cannot account for the natural variability in the essential oils. To determine the boundaries of the natural isotopic values, C-14 radioactive isotope activity assessment was undertaken, which allows for the determination of the genuineness of samples that are not assessed using multistable isotope approaches. Additional studies evaluating C-14 activity of a noncompliant sample using IRMS identified a C-14-labeled synthetic methyl salicylate adulteration.

Since photocatalytic reactions are almost consistent with the concept of green chemistry, substance conversion using photocatalysts has recently attracted the attention of researchers in the fields of organic chemistry, physical chemistry and material chemistry. We investigated photoinduced ring hydrogenation of phenol over a metal-loaded titanium(IV) oxide (TiO2) photocatalyst without the use of H-2 gas and we report here the effects of various parameters, including the type and amount of metal co-catalyst loaded on TiO2 and the kinds of solvents and hole scavengers, on the ring hydrogenation. We found that the combination of an Rh co-catalyst, water and oxalic acid resulted in the highest yield of cyclohexanol. Detailed analyses revealed that phenol was first hydrogenated to cyclohexanone via keto-enol tautomerism of cyclohexenol followed by hydrogenation of cyclohexanone to cyclohexanol and that adsorption of phenol onto Rh-TiO2 is a factor of great importance for the ring hydrogenation.
