Making use of computational approaches like virtual screening of compound libraries are essential steps in drug discovery mission. Several thousands of ligands and their analogs need to be computationally modeled and tested during early stages of drug discovery in order to identify the best molecule with desired characteristics against the target protein which causing the disease. Manual sketching of ligands and their analogs is a time consuming approach with high degree of human errors involved. eAnalogs is a novel computational algorithm to override the manual methods. eAnalogs is a fast, reliable web-accessible software for construction of automated ligand analog libraries. The algorithm is based on simple random sample statistical approach to create each analog of pre-defined atoms or functional groups with equal selection probability. The de novo ligand design tool helps medicinal chemists to rapidly and accurately generate hundreds of analogs from basic 2-dimensional chemical scaffold. The algorithm is capable of generating multiple analogs from single input chemical structure by adding user-defined atoms, functional groups and ring structures to the selected positions in a combinatorial manner. Software allows users to download result library in PDF and Structure Data Formats (SDF) that can be further used for processing virtual High Throughput Screening (vHTS), Quantitative Structure-Activity Relationship (QSAR), Lead Identification and Optimization techniques.

Based on the current economic and environmental analysis of the textile waste streams, textile waste alone can be a promising source of renewable energy. To realize that, catalyst-supported pyrolysis was used in the present research to treat textile waste and convert it into value-added energy carriers while attempting to minimize consumption of consumable chemicals (catalysts) and pyrolysis time and maximize the yield of valuable bio-oil and gases (Methane and Hydrogen). Pyrolysis was conducted on waste jeans (a major fraction of textile waste, rich in cellulose/cotton) with different dye colors (black and blue) and dye-originating heavy metals (used as a self-catalysts). Waste jeans of both colors were pyrolyzed in original condition and after acid leaching to remove the heavy metals for comparison. Also, the pyrolysis experiments were performed according to Technology Readiness Levels (TRL) concept, particularly in laboratory and pilot scale phases. At the first phase, Differential thermal analysis/Thermogravimetric analysis/3D-Fourier-Transform Infrared spectroscopy was employed to simulate the pyrolysis on a lab scale (fundamental level of TRL) and study the thermal and chemical decomposition of the selected samples up to 800 C. At the second stage, a pilot pyrolysis plant was built (based on the fundamental results received from lab scale) to simulate the industrial energy conversion conditions and obtain the data needed to apply the developed approach at industrial scale. The developed plant consisted of four units: pyrolysis reactor (capacity 300 g, Nitrogen ambient, and max. temp. 800 C), gas purification unit, instantaneous gas composition analysis unit (to study the effect of pyrolysis temperature on the generated Oxygen, Nitrogen, Carbon Monoxide, Carbon dioxide, Methane, and Hydrogen gases), and gas products collection unit. The pyrolysis products were analyzed using Gas Chromatography?Mass Spectrometry, Fourier-Transform Infrared Spectroscopy, elemental analysis, and Scanning Electron Microscope- Energy-dispersive X-ray Spectroscopy. The results showed that the developed technology successfully converted more than 82% of the feedstock into liquid-gas products and that the untreated feedstock had effective bio-oil yield 36?37.6% (depending on the composition of self-catalysts), which was ?20% higher compared to the treated batches; 18% reduction in pyrolysis time of untreated feedstock was achieved as well.

Theories about the origin of life require chemical pathways that allow formation of life?s key building blocks under prebiotically plausible conditions. Complex molecules like RNA must have originated from small molecules whose reactivity was guided by physico-chemical processes. RNA is constructed from purine and pyrimidine nucleosides, both of which are required for accurate information transfer, and thus Darwinian evolution. Separate pathways to purines and pyrimidines have been reported, but their concurrent syntheses remain a challenge. We report the synthesis of the pyrimidine nucleosides from small molecules and ribose, driven solely by wet-dry cycles. In the presence of phosphate-containing minerals, 5?-mono- and diphosphates also form selectively in one-pot reactions. The pathway is compatible with purine synthesis, allowing the concurrent formation of all Watson-Crick bases.

A series of novel quinazolines as tubulin inhibitors occupying three zones of colchicine domain have been designed and synthesized inspired by the recently disclosed crystal structure of verubulin analogue 6 with tubulin. Among the newly synthesized compounds, 19c showed noteworthy potency against K562, HepG2, KB, HCT-8 and MDB-MB-231 cancer cells. In vitro microtubule polymerization assays identified 19c as a potent tubulin assembly inhibitor, the binding mode of which with tubulin was confirmed by molecular modeling studies to occupy three zones of tubulin domain. Furthermore, 19c disrupted the intracellular microtubule network, caused G2/M phase arrest, induced cell apoptosis and depolarized mitochondria of K562 cells. 19c also reduced the cell migration and disrupted the capillary-like tube formation of human umbilical vein endothelial cells (HUVECs). Importantly, 19c significantly and dose dependently inhibited tumor growth in H22 liver cancer xenograft mouse model. All these results suggested that 19c deserves further research as a novel and potential anti-tubulin agent for the treatment of cancers.

The reactions of enaminones with dimethyl diazomalonate were investigated in the presence of copper(II) acetylacetonate. From the reaction of (E)-3-[methyl(phenyl)amino]-1-phenylprop-2-en-1-one (6c), dimethyl 2-[methyl(phenyl)amino]-4-oxonaphthalene-1,1-(4H)-dicarboxylate, was unexpectedly obtained as the major product. Quinoline derivatives were formed as the major products in the case of N-methyl-p-anisidino and N-methyl-p-toluidino enaminones. The reactions of acetyl enaminones were also realized, and quinoline derivatives were isolated as the major products. 3H- and 5H-dihydrofurans were also formed as side products in these reactions. These results differ from those reported earlier on the reactions of tertiary enaminones with carbenes/metal carbenes.

Systematic SAR studies on the HTS hit pyridine-2-carboxylic acid thiazol-2-ylamide (PACT) analogues revealed that the scaffold of PCAT is indispensable for the inhibition of type I MetAP. For effective inhibition of the enzyme, the most suitable position to modify is the 3-position of the pyridine ring of PCAT, and the best substituents are those containing O or N atoms connected directly with the pyridine ring. These findings provide useful information for the design and discovery of more potent inhibitors of type I MetAPs.

Calorimetry provides an accurate and reliable method to determine the enthalpies of formation of organic molecules in the gas phase. From the experimental formation enthalpies and the absolute entropies, obtained by theoretical calculations, it is possible to perform Gibbs energy calculations. This thermodynamic function is widely used to describe various thermodynamic processes, such as chemical equilibrium, and allows the calculation of equilibrium constants. The specific standard combustion energies of 3,5-dimethylisoxazole-4-carboxylic acid, 5-methylisoxazole-3-carboxylic acid, 5-amino-3-methylisoxazole, and 3-amino-5-methylisoxazole were determined by using a combustion calorimeter. The sublimation enthalpies of the compounds were determined by means of the Knudsen effusion technique. From these values, the molar standard enthalpy of formation in gaseous phase of each compound was calculated. Theoretical calculations at the G3 and G4 levels were performed, and a study of the molecular and electronic structure of these compounds was carried out. The calculated enthalpies of formation are in very good agreement with the experimental values. From both the experimental and theoretical results, five gas phase chemical equilibria were studied: one of isomerization, two of CO2 loss, and two of NH3 loss. The equilibrium constants for each process were calculated, which allow prediction of the direction of the chemical process from a thermodynamic viewpoint.
