A Quantitative Structure-Activity Relationship (QSAR) approach for classification was used for the prediction of compounds as active/inactive relatively to overall biological activity, antitumor and antibiotic activities using a data set of 1746 compounds from PubChem with empirical CDK descriptors and semi-empirical quantum-chemical descriptors. A data set of 183 active pharmaceutical ingredie...

The silylium ion-catalysed reduction of carbonyl compounds to the alcohol oxidation level is accomplished by exploiting the unique reactivity of a ferrocenyl-substituted silane.

Although traditionally natural products have played an important role in drug discovery, in the past few years most Big Pharma companies have either terminated or considerably scaled down their natural product operations. This is despite a significant number of natural product-derived drugs being ranked in the top 35 worldwide selling ethical drugs in 2000, 2001, and 2002. There were 15 new nat...

Nitrogen-containing compounds are core parts not only of natural and synthetic medicines but also of biologically active compounds including natural products. This review focuses on the development of new synthetic reactions for nitrogen-containing compounds via three methodologies: the reductive photocycloaddition reaction of enamides, radical addition reaction, and nucleophilic addition react...

benzyl chloride and tin powder were used to prepare dibenzyltin dichloride according to a literatureprocedure. in this study, ir spectroscopy, homo-lumo energy gap, nbo analysis, polarizability,some geometrical parameters, natural charge and electrical potential of atoms, global hardness,electronic chemical potential, global electrophilicity index, and molar volume of dibenzyltindichloride were...
