摘要: A method of comparing two conformers in which any score is obtained by determining the field value for molecule A at the coordinates of molecule B's field point. Molecule B's field point does not have to be very close to molecule A's field point to get a good overlay score: it just needs to be in a region where molecule A's field is large. This overcomes a limitation of conventional pseudo-Coulombic scoring in which a low score is achieved when extrema of large extent overlap but have their minimum points widely separated. The method can be applied to molecular mechanics modelling using atom centred charges (ACCs) and extended electron distributions (XEDs) as well as to quantum mechanics models.

摘要: A computer system comprising a database (100) having a plurality of records, is provided. Each record comprises a filed point representation representing field extrema for a conformation of a chemical structure. The database may include records for multiple conformations of the same chemical structure. Each record can have a searchable index of the filed point representation. In one embodiment the index is bit string. An indexing mechanism for generating an index, a searching mechanism for searching the database and a graphical user interface to enable a user to interface with the database (100) are also provided.
