The curated Nat-UV DB database was characterized by calculating six physicochemical properties of pharmaceutical interest, namely: molecular weight (MW), octanol/water partition coefficient (ClogP), topological surface area (TPSA), number of rotatable bonds (RB), number of H-bond donor atoms (HBD), and number of H-bond acceptor atoms (HBA). The statistical analysis was done with the program DataWarrior v.06 , by calculating the mean, median, and standard deviation of the calculated properties. Based on these statistics Nat-UV DB was further compared with other databases (LANAPDB, BIOFACQUIM, UNIIQUIM, and approved drugs from DrugBank) (Table ). The systematic comparison was generated using the Python programming language. The code is freely available at .
