A new version of the award-winning site: ** WebMolecules.com ** is now available at http://www.webmolecules.com Visualize molecules in 3D - real-time on the Web - for FREE! New Features: -------------------------------------------------------------- - Improved SEARCH capabilities. You can search the entire WebMolecules Library by formula. Exact matching is used to search the entire database. Partial matching is also used to search our Top 2000. - SEARCH can now accept formula strings in any order. Previously, there was a "CH alpha" order restriction. http://www.webmolecules.com/search.shtml - Another 25,000 CAS-indexed molecular models have been added. We now have over 125,000 molecular models on-site. Search for these by CAS number or exact formula. http://www.webmolecules.com/search.shtml December's Molecule -------------------------------------------------------------- Thalidomide http://www.webmolecules.com/cgi-bin/webmolpage.cgi?thalidmd.m3d Formula: C13H10N2O4 Weight: 258.233(1) g/mol Originally prescribed as a sedative/hypnotic drug to fight morning-sickness in the '50's and '60's. Banned in the early 1960s after causing severe birth defects, mostly in Europe and Canada. The drug was never approved for distribution in the United States. Thalidomide is in a class of drugs called angiogenesis inhibitors. It disrupts growth of blood vessels by attacking the cells that form their walls. Without such vessels, tumors are starved of nutrients and cannot grow. Clinical trials indicate some effectiveness against: advanced multiple myeloma, prostate cancer, and glioblastoma. Second major mechanism of action: blocks overproduction of Tumor Necrosis Factor (TNF), a naturally-occurring inflammatory protein implicated in a number of diseases, such as: Crohn's, rheumatoid arthritis, diabetes, and the inflammatory complications of leprosy. Currently offered as Thalomid(R) by Celgene of Warren, NJ Other Recent WebMolecules.com Upgrades and New Features -------------------------------------------------------------- - Email Models to Friends.
