Synthesis and spectral properties of new hetarylazo indole dyes

A series of new hetarylazo indole dyes were synthesized by azo coupling of 2-phenyl-, 2-methyl-, and 1-methyl-1-phenyl-1H-indole with diazonium salts derived from 5-methylsulfanyl-1H-1,2,4-triazol-3-amine, 1H-1,2,4-triazol-3- amine, 5-methylisoxazol-3-amine, and 5-amino-1,3,4-thiadiazole-2-thiol. The dyes were characterized by the IR spectra, electronic absorption spectra in the UV and visible regions, and 1H NMR and mass spectra. The effects of solvent nature, acidity of the medium, temperature, and concentration on the electronic absorption spectra in the visible region and the dependence of the color of the dyes on the nature of heterocyclic fragment were examined.

An unusual substitution reaction directed by an intramolecular re-arrangement

Secondary amines and thiols undertake a substitution reaction on the side chain of 2-bromoethyl-pyridinium derivatives ‘directed’ by an intramolecular re-arrangement. Experimental investigations strongly indicate that the reaction is initiated by an alpha addition of the nucleophile onto the iminium moiety of the N-heteroaromatic cation, followed by a cyclisation and an oxidative ring opening. This novel substitution process is able to occur with less reactive nucleophiles that would not undergo conventional substitution with ‘isolated’ bromoethyl moieties.

Carbolithiation of S-alkenyl-N-aryl thiocarbamates: Carbanion arylation in a connective route to tertiary thiols

S-Alkenyl-N-arylthiocarbamates are formed from allylic alcohols by sigmatropic rearrangement and isomerization or C=C bond cleavage. They undergo carbolithiation with a range of organolithium reagents, generating benzyllithium intermediates in a stereospecific manner which may undergo N to C aryl migration to yield thiocarbamates with tertiary substituents. A simple base-promoted alcoholysis reveals a series of hindered tertiary thiols with branched carbon skeletons.

Synthesis of pyridine and spiropyridine derivatives derived from 2-aminoprop- 1-ene-1,1,3-tricarbonitrile together with their c-Met kinase and antiproliferative evaluations

Background: Among a wide range of pyridines, 3-cyanopyridines acquired a special attention due to their wide range of pharmacological activities especially the therapeutic activities. Many pharmacological drugs containing the pyridine nucleus were known in the market. Objective: The aim of this work was to synthesize target molecules not only possess anti-tumor activities but also kinase inhibitors. To achieve this goal, our strategy was to synthesize a series of 3-cyanopyridine derivatives using 2-aminoprop-1-ene-1,1,3-tricarbonitrile (1) as the key starting material for many heterocyclization reactions. Method: Muticoponent reactions were adopted using compound 1 to get different pyridine derivatives that were capable for different heterocyclization reactions. Results: Antiproliferative evaluations and c-Met kinase, Pim-1 kinse inhibitions were perform where some compounds gave high activities. Conclusion: Compounds that showed high antiprolifeative activity were tested gor c-Met-independent and the results showed that compounds 5c, 5e, 5f, 7c, 7f and 16d were more active than foretinib. The Pim-1 kinase inhibition activity of some selected compounds showed that compounds 5e and 16c were high potent to inhibit Pim-1 activity.

Effect of structural modification of enol-carboxamide-type nonsteroidal antiinflammatory drugs on COX-2/COX-1 selectivity

Meloxicam (5), an NSAID in the enol-carboxamide class, was developed on the basis of its antiinflammatory activity and relative safety in animal models. In subsequent screening in microsomal assays using human COX-1 and COX-2, we discovered that it possessed a selectivity profile for COX-2 superior to piroxicam and other marketed NSAIDs. We therefore embarked on a study of enol-carboxamide type compounds to determine if COX-2 selectivity and potency could be dramatically improved by structural modification. Substitution at the 6- and 7-positions of the 4-oxo-1,2-benzothiazine-3- carboxamide, alteration of the N-methyl substituent, and amide modification were all examined. In addition we explored several related systems including the isomeric 3-oxo-1,2-benzothiazine-4-carboxamides, thienothiazines, indolothiazines, benzothienothiazines, naphthothiazines, and 1,3- and 1,4- dioxoisoquinolines. While a few examples were found with greater potency in the COX-2 assay, no compound tested had a better COX-2/COX-1 selectivity profile than that of 5.

Pyridines and Imidazopyridines with medicinal significance

Pyridine and pyridine-fused ring systems are ubiquitous in medicinal research and demonstrate such diverse pharmacological benefits as anticonvulsant therapies, treatment for fungal and bacterial infections as well as chemotherapy agents. For example, imidazo[1,2-a]pyridines have exhibited a broad range of activity as antiviral, antibacterial, analgesic, antipyretic, and antiinflammatory agents. Indeed many advances in the development of novel synthetic approaches to the pyridines and their fused counterparts are designed around the relevance of these systems to pharmacological research. Moreover, pyridine-based natural products with interesting biological activity continue to be discovered each year. This article highlights recent (2004-2014) discoveries related to the medicinal and pharmacological significance of pyridines, imidazo[1,2-a]pyridines, quinolones and a few other pyridine-fused compounds and is organized around their type of biological activity.

Investigating the composition and degradation of wool through EGA/MS and Py-GC/MS

Wool has been the most widely used textile fiber in Europe since the Iron Age. It was largely employed to weave fabrics and clothes, and also for artistic purposes such as producing tapestries. This kind of artworks is among the most fragile of our heritage and is often in bad preservation conditions. Thus, the knowledge on the degradation processes of wool fibers is crucial for conservation issues. In the present study, we tested the potentialities of Pyrolysis coupled with Gas Chromatography and Mass Spectrometry (Py-GC/MS) and Evolved Gas Analysis coupled to Mass Spectrometry (EGA/MS) for the characterization of woolen reference samples, also subjected to artificial ageing, and of historical and archeological samples. The reference sheep wool yarns were prepared with different mordants and dyes, and have been analyzed both after storage in the dark for three years after preparation, and artificially aged for different time intervals and at different relative humidity values. We created a detailed pyrolysis database, evidencing the phenomena occurring with ageing and including camel wool for comparison. The ageing process undergone by the proteinaceous fraction of wool has also been investigated through monitoring specific fragment ions in the EGA profiles. The relevant parameters affecting the degradation process identified in this study match those assessed in previous investigations by different and complementary techniques, thus validating our approach. We proved that the novel approach based on EGA/MS is suitable for quickly assessing the conservation conditions of the woolen yarns and represents an advantage with respect to more time-consuming and complex methods, such as GC/MS or High Performance Liquid Chromatography (HPLC).

Facile Synthesis, Structural Activity Relationship, Molecular Modeling and In Vitro Biological Evaluation of New Urea Derivatives with Incorporated Isoxazole and Thiazole Moieties as Anticancer Agents

A new series of isoxazolyl and thiazolyl urea derivatives was synthesized, fully characterized and evaluated in vitro as anticancer agents. The chemistry involves a facile protocol for the preparation of urea derivatives 12?22 through the reaction of isocyanates (p-tolylsulfonyl isocyanate, p-tolyl isocyanate, benzoyl isocyanate and ethylisocyanate) 8?11 with the corresponding aminoisoxazoles and aminothiazoles 2, 3, 6 and 7. The cytotoxicity of the synthesized compounds 12?22 were evaluated using human lung adenocarcinoma cell line (A549), cervical cancer cell line (HeLa), and breast cancer cell line (MCF7). All novel compounds (except compounds 12, 17, and 18) were potential cytotoxic against lung cancer as it displayed IC50s less than the reference drug (5-Fluro uracil (5FU)). All tested compounds (except 15 and 19) showed strong inhibition of breast cancer cell line even much better than the 5FU. The tested compounds were less cytotoxic against cervical cancer except compounds 16, 19, 20, and 21. The molecular docking studies of the synthesized compounds against the three different proteins Janus kinase 2 (JAK2), cyclin dependent kinase-2 (CDK2), and B-cell lymphoma-2 (BCL2) that are major proteins involved in pathogenesis of cancer were discussed. The molecular-docking analyses revealed that compounds 13, 14 and 20 were the best docked ligand compared to reference docked ligands against the tested targeted proteins. In conclusion, the urea derivatives 13 and 14 were the most promising compounds with lowest IC50s against the tested cancer cell lines, and they displayed the lowest binding energies, critical hydrogen bonds and hydrophobic interactions with the molecular targets compared to other tested compounds.
