Abstract
Objective: Drug candidate compounds that are going to be
synthesized have to reach body tissues and show minimum toxic effects within
the body. Partition coefficient (log P), which is a physicochemical parameter
of Quantitative Structure- Activity Relationship subject, effects the
pharmacokinetical characteristic of the compound. In this context, researchers
tend to use log P prediction softwares to save both time and resources in their
drug development studies. Although, these softwares do not give a true value.
In this study, softwares that have being used were tested. The one that gets
approved for its accuracy can give some clues on the value of partition
coefficient, before determining it experimentally.
Material and Method: In the following dataset, which
comprises of 94 compounds, logP values from literature and values that have
been calculated with softwares such as ACD/iLab 2.0, ALOGPS 2.1 ve
Molinspiration have been compared. By calculating the deviations, most reliable
of these three has been selected. SMILES notations of the compounds has been
used as an input for the calculation.
Result and Discussion: According to the calculation results of 94 compounds, Molinspiration log
P, which has the lowest average deviation value, was selected as most reliable
log P prediction software. By using this software, scholars can comment on
partition coefficients of their synthesized compounds. Therefore, hopefully
they can save both time and resources.
