A number of very powerful molecular-modelling systems are now available commercially and we mention a few of these here. Typically, each consists of a suite of programs sharing a common data structure so that the components of a system may be acquired selectively.
The Chem-X system, from Chemical Design Ltd, enables models to be developed from sketch-pad input, provides for their geometrical optimization and interfaces the result to Gaussian80 for quantum-mechanical calculations.
MACCS , from Molecular Design Ltd, and related software (Allinger, 1976; Wipke et al., 1977; Potenzone et al., 1977) has similar features and also has extensive database-maintenance facilities including data on chemical reactions.
Sybyl , from Tripos Associates (van Opdenbosch et al., 1985), also builds from sketches with a standard fragment library, and provides interfaces to quantum-mechanical routines, to various databases and to MACCS.
Insight II (Section 3.3.3.1.7) is available from Biosym and GRAMPS (Section 3.3.3.1.4) is available from T. J. O'Donnell Associates.
