Optimization of a small molecule probe that restores e-cadherin expression.

Area of Science:

• Molecular Biology
• Cell Biology
• Medicinal Chemistry

Background:

• E-cadherin is a key transmembrane protein involved in cell-cell adhesion.
• E-cadherin plays a critical role in the epithelial mesenchymal transition (EMT).
• Loss of E-cadherin is associated with cancer progression.

Purpose of the Study:

• To optimize compounds identified through HTS that restore E-cadherin expression in cancer cells.
• To develop novel small molecules targeting E-cadherin restoration.
• To characterize the pharmacokinetic properties of a probe compound for E-cadherin restoration.

Main Methods:

• Medicinal chemistry optimization of previously identified hit compounds.
• In vitro assays to assess E-cadherin restoration at the protein and mRNA level.
• Preliminary pharmacokinetic studies of the optimized compound ML327.

Main Results:

• Optimized compounds restored E-cadherin expression at low micromolar concentrations.
• New chemical entities with improved potency were synthesized.
• Compound ML327 demonstrated suitable properties for use as a research probe.

Conclusions:

• Medicinal chemistry efforts successfully yielded potent E-cadherin-restoring agents.
• The developed compounds represent promising leads for further investigation in cancer therapy.
• ML327 serves as a valuable tool for studying E-cadherin function and restoration.
