Method for characterizing and analyzing 3-D shapes of molecules utilizing steric multiplets

摘要

Steric features inherent in the three dimensional disposition of atoms in molecules can be represented as multiplets using a defined set of steric descriptors. The resulting multiplets can be encoded in a compressed form of bitstring known as a bitmap. Such bitmaps can be generated in compressed form and used to compare individual conformers or ensembles of conformers of molecules to each other without decompression. Such comparisons are useful in molecular similarity analysis, in molecular diversity analysis, in database searching, and in conformational analysis.
