Computational and experimental validation of morin as adenosine deaminase inhibitor

Area of Science:

• Biochemistry
• Enzymology
• Pharmacology

Background:

• Adenosine deaminase (ADA) is a key enzyme in purine metabolism, vital for cell growth and differentiation.
• Elevated ADA activity is linked to pathologies such as malignancy and inflammation, making it a therapeutic target.

Purpose of the Study:

• To investigate the adenosine deaminase inhibitory activity of morin, a bioactive flavonoid.
• To elucidate the interaction mechanism between morin and ADA using computational and biophysical approaches.

Main Methods:

• Enzyme kinetics assays to determine inhibition type.
• Isothermal Titration Calorimetry (ITC) for binding energy analysis.
• Fluorescence quenching, molecular docking, and molecular dynamics simulations to study protein-ligand interactions.

Main Results:

• Morin was identified as a competitive inhibitor of ADA.
• ITC analysis yielded a binding energy of -7.11 kcal/mol.
• Computational studies provided detailed insights into the structural basis of morin-ADA interaction and complex stability.

Conclusions:

• Morin exhibits significant inhibitory effects on ADA activity.
• The findings support morin as a potential therapeutic agent for ADA-related diseases.
• Detailed structural insights into the morin-ADA complex pave the way for further drug development.
