The April update of the award-winning site: ** WebMolecules.com ** is now online at http://www.webmolecules.com Visualize Molecules - in real time - on the Web - in 3D - for FREE! New Features: ----------------------------------------------------------------- - Another 25,000 molecular models have been added. We now have over 200,000 molecular models on-site. - Local (mirror) downloads of the 3D Viewer plug-ins added. No more *Site not responding* messages - hopefully! - Expanded Model Options services ------------------ WebMolecules News Sponsor ------------------ www.chemjobs.net Go to http://www.chemjobs.net for chemistry jobs worldwide - FREE e-mail bulletin of current openings - FREE job vacancy postings ------------------( Please Visit This Sponsor!)------------------ Molecule of the Month ----------------------------------------------------------------- Taxol (paclitaxel) http://www.webmolecules.com/cgi-bin/webmolpage.cgi?taxol.m3d Formula: C47 H51 N O14 Weight: 853.920(1) g/mol Taxol is in the news again. Dr./Sr. Angela M. Hoffman of the University of Portland, Oregon, while researching a cure for a blight that kills hazelnut trees discovered that the trees and their nuts contain paclitaxel (Taxol). Fortuitously, Hoffman had worked previously with yew trees, the heretofore only known natural source of paclitaxel. She said this is the only reason she recognized the chemical and the potential significance of the discovery. Hoffman announced her discovery at the recent national meeting of the American Chemical Society in San Francisco. Taxol(R), which is manufactured by Bristol-Myers Squibb, is used to treat breast and ovarian cancers, Kaposi's sarcoma, and some forms of lung cancer. It is also under investigation for treating psoriasis, polycystic kidney disease, multiple sclerosis and Alzheimer's disease. Although Taxol can be synthesized in the laboratory, this route is currently very complex and therefore too costly to be practical. ------------------ WebMolecules News Sponsor ------------------ Join the Elementalists at SCIENCEbase.com for the latest reactive science communication on the Web from award winning science writer David Bradley. http://www.sciencebase.com/ ------------------( Please Visit This Sponsor!)------------------ Suggestion Box ----------------------------------------------------------------- Is there a new feature you would like to see at WebMolecules?
