Notes: Ciliobrevin A is a hedgehog pathway inhibitor that blocks sonic hedgehog (Shh)-induced hedgehog pathway activation (IC50 = 7 µM).{21061} It disrupts primary cilia formation and inhibits the dynein-dependent microtubial gliding and ATPase activities of the cytoplasmic ATPases associated with various cellular activities (AAA+) family. Ciliobrevin A also inhibits mammalian target of rapamycin complex 1 (mTORC1) activity in uninfected and human cytomegalovirus (HCMV)-infected cells, suggesting that mTORC1 activation requires dynein-dependent transport for cellular activation.{34791}
