Databases of molecular structures

There are now extensive databases of molecular structures and properties. There are some research efforts, such as drug design, in which it is desirable to hnd all molecules that are very similai to a molecule which has the desired property. Thus, there are now techniques for searching large databases of structures to hnd compounds with the highest molecular similarity. This results in hnding a collection of known structures that are most similar to a specihc compound.
