The effort to replace chemical rings forms a large part of the medicinal chemistry practice. This paper describes our effort in developing a comprehensive database of drug rings supported by a web-enabled searching system. Analysis of the rings found in several major chemical databases will be described. The use of the database will be illustrated through application to lead discovery programs for which bioisosteres and geometric isosteres were sought.
