Vismodegib

Vismodegib is an orally active small molecule that inhibits the hedgehog signaling pathway by binding to and inhibiting the transmembrane protein smoothened homologue (SMO). It was discovered by high-throughput screening of a library of small-molecule compounds and subsequent optimization through medicinal chemistry. Since it targets the hedgehog signaling pathway, vismodegib has anti-tumor activity in basal-cell carcinoma. The Hedgehog signaling pathway plays an important role in the development of organs and tissues during embryogenesis. Afterwards, it is silenced in all cells and tissues, except for hair, skin and stem cells. However, dysregulated or aberrant Hedgehog signaling has been associated with basal cell carcinoma pathogenesis. In January 2012, vismodegib was approved by the FDA for the treatment of adult basal cell carcinoma. In July 2013, it was approved by the EMA, and since then, it has been approved by several other countries.
