title: Automated site-directed drug design using molecular lattices.
abstract: Receptor-based drug design is predicated on the knowledge of the structure of a target receptor and the principles of molecule recognition. The objective is to produce a wide diversity of structures that are sterically and electrostatically complementary to a specified receptor site. Many drug-receptor interactions are controlled by a few key receptor groups. This observation leads to a design approach in which one focuses on chemical fragments that putatively interact with the key receptor groups. There then remains the difficult task of joining the fragments into molecular structures that match the spatial patterns of recognition forces in the receptor site. In this paper, we describe a new modeling program, BUILDER, that combines database searching techniques and structure generation algorithms within an interactive graphics modeling environment (MidasPlus). A novel tool for process communication (delegate) is introduced and examples of its use are given. To demonstrate the functionality of the package and its ability to produce novel structures, we examine the active site of HIV-1 protease.
