QSAR(Quantitative Structure Activity Relationship) is a method to estimate physico-chemical properties and
eco-toxicity of a man-made chemical through the statistical analysis of the relation between molecular structure
and activity of the chemical. It can be advantageous since QSAR gives an idea to researchers how a man-made
chemical behaves in the environment where it is discharged without any time-consuming and labor intensive
laboratory experiment. In this study, physico-chemical and toxicological properties of 15 pharmaceuticals were
estimated by applying QSAR. In general, the predicted properties were reasonable good; some of them were
compared with experimental data available in literature. It was concluded that QSAR could be utilized as a tool
to initially screen eco-toxicologically harmful pharmaceuticals.
