The physical descriptors (constitutional and electronic) of tobramycin and its AOT-complex were calculated. The selected descriptors were the total polar surface area, number of hydrogen bond donors, number of hydrogen bond acceptors, molecular globularity, molecular flexibility, LogP (O/W) and the molecular weight. The descriptors were calculated using MOE version 2014.0901 (Chemical Computing Group Inc., Montreal, Canada) after constructing the two investigated drugs utilising the builder tool in the same software to generate the 3D structures of the investigated drugs from their isomeric SMILES obtained from The PubChem Project® [48 (link),49 (link)].
