2nd Generation Database Searching with Chem-X!

Chemical Design announces the development of a new generation of search
engine which can dramatically improve database searching performance. This
will have immediate impact on the speed at which compounds are selected
from databases for biological activity testing by the pharmaceutical
industry. "We are very pleased with the performance of our new search
engine" commented Keith Davies, Technical Director of Chemical Design.
"Even on a Pentium, we can perform substructure searches on a database of
a million molecules in under 15 seconds!" The software can also be used
with UNIX and VMS servers. 

This exciting development ensures Chem-X can rapidly search in-house
databases of discrete molecules and libraries containing millions of
structures, as well as commercial catalogues. With new catalogues of tens
or even hundreds of thousands of molecules becoming available almost every
month, the speed of database searching and loading is critical to
cost-effective drug discovery. 

The new search engine uses functional group keys to accelerate exact,
substructure and similarity searching. Similarity searching is especially
important when selecting molecules from catalogues to test and developing
hypotheses for structure-activity relationships. Fast Clustering
technology, already present in Chem-X, can also be used to select
representative subsets of databases, further reducing the number of
molecules which need to be tested. 

Release of this latest software development coincides with the agreement
with Sigma-Aldrich to supply their catalogue as a Chem-X database and the
availability of the HTS Chemicals collection of current compound
databases. This means that Chemical Design now supplies the largest
collection of databases for searching on PC and Power Macintosh platforms.
