In silico screening and identification of potential GSK3β inhibitors

Area of Science:

• Biochemistry
• Pharmacology
• Computational Chemistry

Background:

• Glycogen synthase kinase-3β (GSK3β) plays a crucial role in various biological processes, including cell proliferation and apoptosis.
• An elevated active/inactive GSK3β ratio is implicated in the development of psychiatric disorders, diabetes, neurodegenerative diseases, and certain cancers.
• GSK3β is recognized as a significant therapeutic target, driving research into novel inhibitors with improved efficacy and reduced side effects.

Purpose of the Study:

• To virtually discover potent inhibitors of GSK3β from a chemical library using computational methods.
• To identify compounds with potential therapeutic value for diseases associated with GSK3β dysregulation.
• To evaluate the safety profile and binding characteristics of identified potential inhibitors.

Main Methods:

• Virtual screening of a chemical library against GSK3β using a multi-step filtering approach.
• Computational analysis including docking simulations to predict binding modes and interactions.
• Assessment of potential toxicity of identified compounds.

Main Results:

• Five compounds from the chemical library were identified as potential GSK3β inhibitors.
• These compounds demonstrated no predicted toxic effects.
• Binding mode analysis indicated that all identified compounds interact with the ATP binding site of GSK3β, with conserved hydrogen bonding patterns.

Conclusions:

• The study successfully identified potential GSK3β inhibitors through computational screening.
• The identified compounds represent promising candidates for further drug development targeting GSK3β-related diseases.
• The conserved binding interactions suggest a viable mechanism for inhibiting GSK3β activity.
