The use of an algorithmic method for small molecule superimpositions in the design of antiviral agents
The inability to reliably predict relative orientations of drug molecules within our series of antipicornavirus agents has severely limited the usefulness of available structure-activity data in the drug design process. A reported method of overlapping molecules has been evaluated to see if it could provide a solution to this problem. Although it initially succeeded remarkably well with a series of molecules whose bound X-ray structures were known, this success was shown to be only a function of the bound conformation of these molecules. Thus, this method did not provide a general solution to the problem at hand.
