Background:

Dipeptides play crucial roles in biological processes.
Predicting biological activities of dipeptides is essential for drug design.
Existing methods for predicting dipeptide properties have limitations.

Purpose of the Study:

To introduce and validate novel Cluj property indices.
To model the Angiotensin-Converting Enzyme (ACE) inhibition activity of 58 dipeptides.
To model the bitter taste activity of 48 dipeptides.

Main Methods:

Utilized Cluj property indices for quantitative structure-activity relationship (QSAR) modeling.
Collected dipeptide data and associated biological activities from existing literature.
Compared model performance against previously reported results.

Main Results:

Cluj property indices demonstrated effectiveness in modeling ACE inhibition.
The indices also showed promise in predicting bitter taste activity of dipeptides.
Results were consistent with and comparable to previous studies.

Conclusions:

Cluj property indices provide a valuable tool for predicting dipeptide biological activities.
This approach can aid in the rational design of peptides with desired properties.
The study highlights the potential of these indices in drug discovery and development.
