Background:

• Psychotomimetic phenylalkylamines represent a class of compounds with significant psychoactive properties.
• Understanding the structural determinants of their activity is crucial for developing targeted therapeutic or research agents.
• Existing predictive models may benefit from incorporating diverse computational approaches.

Purpose of the Study:

• To develop a predictive Quantitative Structure-Activity Relationship (QSAR) model for psychotomimetic phenylalkylamines.
• To explore the utility of combining topological descriptors with quantum chemical parameters for enhanced prediction.
• To validate the predictive power of the developed QSAR model using cross-validation techniques.

Main Methods:

• Application of the Minimum Topological Difference (MTD) method.
• Utilization of a comprehensive set of distance-based topological indices.
• Integration of quantum chemical parameters into a multiparametric regression model.
• Cross-validation analysis to assess model predictability.

Main Results:

• Excellent predictive results were achieved using a multiparametric model.
• The model effectively incorporated MTD parameters and topological indices.
• The inclusion of quantum chemical parameters significantly improved predictive accuracy.
• Cross-validation confirmed the robustness and predictive power of the developed QSAR model.

Conclusions:

• A robust QSAR model integrating MTD, topological, and quantum chemical parameters has been successfully developed.
• This integrated approach provides a powerful tool for predicting the activity of psychotomimetic phenylalkylamines.
• The findings highlight the importance of a multiparametric strategy in QSAR studies for drug discovery and design.
