Drug Design:An Emerging Era of Modern Pharmaceutical Medicines

The term drug design represents mainly to develop new drug, manipulate and/or representation of three-dimensional structure of the molecule and association of physico-chemical properties. A drug has become a valuable and essential tool to medicinal chemists for development of new drugs. Different techniques of drug designing that extend from simply visualizing a small drug molecule on computers for computing the intricate of drug targets interactions on a super computer. Computerized drug designing provides medicinal chemist with information regarding three dimensional structure of molecule, chemical and physical characteristics of a molecule, comparing the structures of drug molecules for visualization of complex formed, prediction about how new related molecules look. Based on these fundamentals we try to explain drug design concept and its need related to pharmaceutical medicines.
