here we inspect the relation between active compounds and molecular complexity. For this study, the fractions of sp 3 atoms (Fsp 3 ) and chiral centers (FCC) were used as complexity metrics based on topological and physicochemical descriptors . Also, Complexity by Bertz and DataWarrior based on graph-theoretical methods were used. All metrics were calculated with RDKit [23] and DataWarrior 5.0.0 .
