Swiss scientists say they have determined there are more than 970 million chemicals suitable for study as potential new drugs. Professor Jean-Louis Reymond and researcher Lorenz Blum, both of the University of Berne, said their study has produced the largest publicly available database of virtual molecules ever reported. The researchers said the rules of chemical bonding allow simple elements such as carbon, hydrogen, oxygen, nitrogen and fluorine to potentially form millions of different...

Like astronomers counting stars in the familiar universe of outer space, chemists in Switzerland are reporting the latest results of a survey of chemical space "” the so-called chemical universe where tomorrow's miracle drugs may reside. The scientists conclude, based on this phase of the ongoing count, that there are 970 million chemicals suitable for study as new drugs. Scheduled for the July 1 issue of the Journal of the American Chemical Society, the study represents the largest...

By squeezing a typical metal alloy at pressures hundreds of thousands of times greater than normal atmospheric pressure, scientists at the California Institute of Technology (Caltech) have created a material that does not expand when heated, as does nearly every normal metal, and acts like a metal with an entirely different chemical composition.The discovery, described in a paper in Physical Review Letters (PRL), offers insight into the exotic behavior of materials existing at high...

Some 14 years ago, a family of biological compounds found in sponges in the South Pacific was shown to have very promising effects in fighting leukemia.  Further studies have been stifled for years however by the scarcity of the substance.But a group of researchers at the Scripps Research Institute has recently discovered a way to circumvent this problem.Using a few basic amino acids, acetylene gas and a tremendous bit of ingenuity, the research team has developed a technique for...

To be useful in real-world applications, a self-assembled monolayer (SAM) of molecules on a surface must have a stable and controllable geometry. Researchers at Penn State and the Sigma-Aldrich company have found a way to control geometry and stability by making SAMs out of different carboranethiol isomers, which are cage-like molecules. The research results will be published in the March 2009 issue of the journal ACS Nano."Our results allow us to control the chemical and physical properties...
