| PROPERTY | Explanation |
| MOLECULAR WEIGHT |
Molecular mass weight(Da). Calculated from the structural formula. |
| MOLECULAR CHARGE |
Total charge of molecule. |
| NUMBER OF DONOR |
Number of hydrogen bond donor atoms. Oxygen or nitrogen bonded with hydrogen atom. |
| NUMBER OF ACCEPTOR |
Number of hydrogen bond acceptor atoms. Oxygen or nitrogen with lone pairs and fluorine. |
| NUMBER OF CHIRAL ATOMS |
Number of chiral atoms, such as asymmetric carbons. |
| LUMO |
Energy of lowest unoccupied molecular orbital (eV), calculated by MOPAC AM1. This value is closely related to photosensitiviy. |
| HOMO |
Energy of highest occupied molecular orbital (eV), calculated by MOPAC AM1. This value is closely related to photosensitivity. |
| LOGS |
Value of the aqueous solubility predicted by the machine learning method using features of chemical groups and the MD simulation (Mashimo et al, 2010). A compound with a higher LOGS is more soluble in water. |
| LOGP |
Octanol/water partition coefficient. The value is also known as a measure of lipophilicity. |
