Potential effective inhibitory compounds against Prostate Specific Membrane Antigen (PSMA): A molecular docking and...

Area of Science:

• Biochemistry
• Computational Chemistry
• Oncology

Background:

• Prostate cancer is a leading cancer in men.
• Prostate-Specific Membrane Antigen (PSMA) is a key target for cancer therapy.
• Developing novel inhibitors is crucial for effective treatment.

Purpose of the Study:

• To identify natural compounds that can suppress Prostate-Specific Membrane Antigen (PSMA) protein.
• To computationally screen and evaluate potential PSMA inhibitors.
• To design more effective inhibitors for prostate cancer treatment.

Main Methods:

• Pharmacophore and ADMET analysis of natural compounds from the ZINC database.
• Molecular docking and molecular dynamics simulations to assess ligand-protein interactions.
• MMPBSA/GBSA analysis to determine binding free energies and inhibition potential.

Main Results:

• Four compounds (Z10, Z06, Z01, Z03) showed significant interactions with PSMA active site residues.
• Binding free energies of selected compounds were comparable to the reference ligand.
• Analysis revealed critical interactions within the S1/S1' pockets, guiding inhibitor design.

Conclusions:

• Identified potent small molecules as potential inhibitors of PSMA.
• Computational approaches successfully guided the discovery of effective PSMA inhibitors.
• These findings pave the way for developing novel immunotoxins and antibody treatments for prostate cancer.
