New approaches to rational drug design

Rational drug design has emerged as a powerful technique. In this review, three new developments in rational drug design are explored. These developments include new methods to find binding sites for small molecules on the surface of a protein, the suggestion that the protein environment may change the shape of a protein sufficiently to alter drug design, and the use of data emerging from structural genomics in drug design. Although these are three new and distinct areas, the insights derived from these studies suggest a reason for the observation that similar drugs do not always bind to a protein in the same manner.
