Hedgehog acyltransferase (Hhat), a membrane-bound O-acyl transferase (MBOAT) protein, is responsible for the palmitoylation of Shh and is crucial to proper Shh signaling. Hhat inhibitors that are capable of preventing Shh palmitoylation and mitigating Shh signaling, and therefore can be used in the treatment and/or prevention of diseases (e.g., proliferative diseases, such as cancer). Provided herein are Hhat inhibitors, such as compounds of Formula (I), (II), and (III), which are useful for the treatment and/or prevention of disease.
