Library Design and QSARRecent progress in high-throughput screening, combinatorial chemistry and molecular biology has radically changed the approach to drug discovery in the pharmaceutical industry. New challenges in synthesis result in new analytical methods. At present, typically 100,000 to one million molecules have to be tested within a short period and, therefore, highly effective screening methods are necessary for today's researchers - preparing and characterizing one compound after another belongs to the past. Intelligent, computer-based search agents are needed and ""virtual screening"" provides solutions Methods and principles in medicinal chemistry ;v. 10.DrugsDesignComputer simulationDrugsTestingComputer simulationElectronic books.DrugsDesignComputer simulation.DrugsTestingComputer simulation.615615.19615.1900285615/.19Böhm Hans-Joachim902275Schneider Gisbert1965-855861MiAaPQMiAaPQMiAaPQBOOK9910144110503321Virtual screening for bioactive molecules2170852UNINA
