Chemical Disruption of Wnt-dependent Cell Fate Decision-making Mechanisms in Cancer and Regenerative Medicine

Area of Science:

• Biochemistry
• Molecular Biology
• Medicinal Chemistry

Background:

• Wnt proteins are key cell-to-cell signaling molecules regulating transcriptional programs essential for tissue generation.
• Cellular responses to Wnt signaling are critical intervention points for directing cell fate in therapeutic applications.
• Small molecules modulating Wnt signaling serve as vital tools for studying Wnt protein function in various biological contexts.

Purpose of the Study:

• To review medicinal chemistry efforts focused on small molecules targeting Porcupine (Porcn) and Tankyrase (Tnks).
• To examine the implications of these molecules' novel mechanisms of action for drug development.
• To highlight their contribution to understanding the druggable genome and cell fate decision-making.

Main Methods:

• Focus on first-in-class small molecules targeting Wnt pathway components.
• Analysis of medicinal chemistry strategies for developing these targeted molecules.
• Review of biological contexts including cancer, development, and regeneration.

Main Results:

• Development of small molecules targeting Porcupine (Porcn) acyltransferase and Tankyrase (Tnks) poly-ADP-ribosylases.
• Demonstration of these molecules as powerful probes for Wnt protein function.
• Expansion of the chemical toolkit for influencing cell fate decisions.

Conclusions:

• Medicinal chemistry targeting Porcn and Tnks has significantly advanced the understanding of the druggable genome.
• These small molecules provide unprecedented opportunities for therapeutic interventions in Wnt-related diseases.
• The study underscores the potential of chemical modulators in directing cell fate for regenerative and therapeutic purposes.
