Choose New Chem-X for Lead Generation!

Chemical Design is pleased to announce an exciting new module within the
New Chem-X suite for Lead Generation: Fast Clustering. Random screening of
candidates for new drugs is expensive and time consuming for
pharmaceutical organizations - our innovative Fast Clustering can reduce
this overhead by up to 80% and conserve sample stocks.

Many pharmaceutical organizations store vast quantities of structural (and
other) data in chemical databases, including compounds available for
testing. Using a novel algorithm, Fast Clustering can group databases in
excess of 50,000 structures into subsets of similar compounds.
Representative members of these subsets are then easily extracted to
provide a further subset reflecting the diversity of the database
screening.

The algorithm used in Fast Clustering groups molecules in the 3D database
based on the similarity of their pharmacophores - the description of the
arrangement and nature of key functional groups. Tests show that databases
in excess of 40,000 structures can be clustered in under 13 hours on a
UNIX workstation.

The new Fast Clustering module for lead generation is part of New Chem-X's
powerful integrated modeling and database drug discovery tools. New Chem-X
is supported on a full range of hardware platforms including MS-Windows,
DOS, Apple Macintosh and UNIX workstations such as Silicon Graphics, IBM
RS/6000 and Digital Alpha AXP.

New Chem-X is used by over 600 research sites world-wide, including
divisions of most multi-national pharmaceutical companies. The software is
probably best known for its 3D database pharmacophore searching
capabilities where Chemical Design has demonstrated that its technology is
2 years ahead of the competition. Its advanced capabilities are proven for
success, yielding new patentable drugs now in development.
