Ciliobrevin D
Based on 6 publication(s) in Google Scholar
Ciliobrevin D is a cell-permeable, reversible and specific inhibitor of AAA+ ATPase motor cytoplasmic dynein. Ciliobrevin D inhibits Hedgehog (Hh) signaling and primary cilia formation. Ciliobrevin D inhibits dynein-dependent microtubule gliding and ATPase activity in vitro.

Biological Activity
Cells treated with Ciliobrevin D exhibits abnormal (unfocused, multipolar, or collapsed) spindles with disrupted γ-tubulin localization in NIH-3T3 cells. Similar Ciliobrevin-induced spindle defects are observed in HeLa cells, although to a lesser extent. Ciliobrevin D addition also reversibly disrupts the pre-formed spindles of metaphase-arrested cells and reduces overall microtubule levels[1].
.?
Ciliobrevin D reversibly inhibits melanosome aggregation, but the non-cilia-disrupting derivative had no discernible effect at comparable doses. Ciliobrevin D similarly abrogates the movement of peroxisomes in Drosophila S2 cells[1].
