Similarity searching. CHIRBASE

Auto Search This button initiates from a structure query two or three automated series of search exact and substructure searches in local desktop versions exact, substructure and similarity searches in network version (under ISIS/Host). All the result lists are saved in CHIRBASE using exact-auto , SSS-auto and SIMXX %-auto names. XX is the highest similarity search value (from 80 % to 40 %) allowing to retrieve hits in CHIRBASE. The records in all the lists are unique. The SSS-auto list does not include records that are in the exact-auto list. The SIMXX %-auto list does not include records that are in exact and SSS-auto lists. 

CHIRBASE Database Current Status and Derived Research Applications using Molecular Similarity, Decision Tree and 3D Enantiophore Search... 

From these preliminary results, we can assume that such enantiophore queries could be used to search in a database of compounds with unknown enantioselectiv-ities. With respect to the percentage of resolved samples that are retrieved in CHIRBASE, the resulting list should contain a similar yield of compounds providing favorable specific interactions with the CSP receptor binding sites.
