Cell-to-cell signaling molecules such as the Wnt proteins that directly influence
the expression of cell-type specific transcriptional programs are essential for
tissue generation in metazoans. The mechanisms supporting cellular responses to
these molecules represent potential points of intervention for directing cell
fate outcomes in therapeutic contexts. Small molecules that modulate Wnt-mediated
cellular responses have proven to be powerful probes for Wnt protein function in
diverse biological settings including cancer, development, and regeneration.
Whereas efforts to develop these chemicals as therapeutic agents have dominated
conversation, the unprecedented modes-of-action associated with these molecules
and their implications for drug development deserve greater examination. In this
review, we will discuss how medicinal chemistry efforts focused on first in class
small molecules targeting two Wnt pathway components--the polytopic Porcupine
(Porcn) acyltransferase and the cytoplasmic Tankyrase (Tnks)
poly-ADP-ribosylases--have contributed to our understanding of the druggable
genome and expanded the armamentarium of chemicals that can be used to influence
cell fate decision-making.
