Ere, we mention some examples of such studies. Schwaighofer et al. [13] analyzed compounds examined by the Bayer Schering Pharma when it comes to the percentage of compound remaining after incubation with liver microsomes for 30 min. The human, mouse, and rat datasets have been employed with about 1000200 datapoints every single. The compounds were represented by molecular descriptors generated with Dragon application and both classification and regression probabilistic models were developed with all the AUC on the test set ranging from 0.690 to 0.835. Lee et al. [14] utilized MOE descriptors, E-State descriptors, ADME keys, and ECFP6 fingerprints to prepare Random Forest and Na e Bayes predictive models for evaluation of compound apparent intrinsic clearance with the most powerful Adiponectin Receptor Agonist manufacturer approach reaching 75 accuracy around the validation set. Bayesian method was also applied by Hu et al. [15] with accuracy of compound assignment for the steady or unstable class ranging from 75 to 78 . Jensen et al. [16] focused on additional structurally consistent group of ligands (calcitriol analogues) and developed predictive model determined by the Partial Least-Squares (PLS) regression, which was identified to become 85 efficient in the stable/unstable class assignment. Alternatively, Stratton et al. [17] focused around the antitubercular agents and applied Bayesian models to optimize metabolic stability of oneof the thienopyrimidine derivatives. Arylpiperazine core was deeply examined when it comes to in silico evaluation of metabolic stability by Ulenberg et al. [18] (Dragon descriptors and Help Vector PAR2 Compound Machines (SVM) have been used) who obtained functionality of R2 = 0.844 and MSE = 0.005 on the test set. QSPR models on a diverse compound sets had been constructed by Shen et al. [19] with R2 ranging from 0.five to 0.six in cross-validation experiments and stable/unstable classification with 85 accuracy around the test set. In silico evaluation of particular compound property constitutes excellent help from the drug design campaigns. Even so, offering explanation of predictive model answers and acquiring guidance on the most advantageous compound modifications is a lot more useful. Searching for such structural-activity and structural-property relationships is often a subject of Quantitative Structural-Activity Partnership (QSAR) and Quantitative Structural-Property Connection (QSPR) studies. Interpretation of such models might be performed e.g. by means of the application of Many Linear Regression (MLR) or PLS approaches [20, 21]. Descriptors significance may also be relatively easily derived from tree models [20, 21]. Not too long ago, researchers’ consideration is also attracted by the deep neural nets (DNNs) [21] and a variety of visualization methods, for example the `SAR Matrix’ technique developed by GuptaOstermann and Bajorath [22]. The `SAR Matrix’ is determined by the matched molecular pair (MMP) formalism, that is also extensively utilised for QSAR/QSPR models interpretation [23, 24]. The operate of Sasahara et al. [25] is among the most current examples on the improvement of interpretable models for research on metabolic stability. In our study, we concentrate on the ligand-based method to metabolic stability prediction. We use datasets of compounds for which the half-lifetime (T1/2) was determined in human- and rat-based in vitro experiments. Immediately after compound representation by two keybased fingerprints, namely MACCS keys fingerprint (MACCSFP) [26] and Klekota Roth Fingerprint (KRFP) [27], we create classification and regression models (separately for hu.
