Computational analysis reveals restricted molecular shape diversity across commercial drugs, suggesting narrow exploration of chemical space.

To systematically analyze the structural shapes and evaluate framework diversity across commercially available drug molecules.
Categorized molecular structures of 5,120 commercial drugs into ring, linker, framework, and side-chain components.
Evaluated molecular diversity using two framework definitions: a 2D topological shape analysis excluding atom types and bond orders, and an atom-specific analysis incorporating hybridization and bond order.
Topological shape analysis identified 1,179 unique frameworks among 5,120 compounds, with the 32 most frequent frameworks accounting for 50% of all drugs.
Atom-specific framework analysis identified 2,506 distinct frameworks, with the 42 most common frameworks representing 25% of the drug database.

Bemis et al. (1996) studied this question.
