Hedgehog/Smoothened antagonists are a class of compounds designed to inhibit the Hedgehog signaling pathway. This pathway plays a pivotal role in embryonic development and tissue regeneration, and its dysregulation is associated with various cancers, including basal cell carcinoma. By blocking the pathway's key components, such as Smoothened, these antagonists show potential in treating cancers driven by abnormal Hedgehog signaling. They're a promising area of research in the quest for innovative cancer therapies and could have applications in various other medical conditions connected to Hedgehog pathway dysfunction.
