SwissBioisostere: a database of molecular replacements for ligand design

The SwissBioisostere database (http://www.swissbioisostere.ch) contains information on molecular replacements and their performance in biochemical assays. It is meant to provide researchers in drug discovery projects with ideas for bioisosteric modifications of their current lead molecule, as well as to give interested scientists access to the details on particular molecular replacements. As of...

Workflow-based identification of bioisosteric replacements for molecular scaffolds

Scaffolds are defined as the core structure of a molecule connecting different substituents or functional groups. Defining bioisosteric alternative scaffolds for lead structures is an important task in drug design to improve e.g. the activity, bioavailability or selectivity of the structures concerned [1]. In this context, bioisosteric replacement means changing the scaffold structure while ret...

Hard Tissue Replacements

The use of biomaterials to restore the function of traumatized or degenerated connective tissues and thus improve the quality of life of a patient has become widespread. In the past, implants were designed with insufficient cognizance of biomechanics. Accordingly, the clinical results were not very encouraging. An upsurge of research activities into the mechanics of joints and biomaterials has ...

Toxicology of chlorofluorocarbon replacements.

Chlorofluorocarbons (CFCs) are stable in the atmosphere and may reach the stratosphere. They are cleaved by UV-radiation in the stratosphere to yield chlorine radicals, which are thought to interfere with the catalytic cycle of ozone formation and destruction and deplete stratospheric ozone concentrations. Due to potential adverse health effects of ozone depletion, chlorofluorocarbon replacemen...
