UORSY Mixed Shapes Library

Shape of small molecule compounds has been postulated as an important factor for efficient binding to a biological target. Principal moments of inertia (PMI) is one of the widely accepted1 approaches to characterize shape diversifying compounds as disc-like, rod-like, and sphere-like. According to PMI analysis, most commercially available collections are enriched with rods or discs but not spheres.2 3D shaped molecules, however, are commonly found among natural products and a number of publications showing advantages of 3D structures over planar ones has been released.3,4

We offer a mixed shapes library with enriched fraction of sphere-like molecules that allows for equal testing all possible shapes (Figure 1). To ensure high quality of the library, we applied PAINs filtering and “overused” substances removal that yielded a set of 867 lead-like compounds.
