Field of application
Ciliobrevin D is a cell-permeable, reversible, specific inhibitor of cytoplasmic dynein, blocks dynein-dependent microtubule gliding and ATPase activity while sparing kinesin dependent cellular trafficking.

Description: 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[1][2].
Target: Cytoplasmic dynein[1][2]
In Vivo: Knockdown of Dync1h1 or inactivation of dynein 1 by Ciliobrevin D in the testis in vivo perturbs spermatogenesis. Knockdown of Dync1h1 or the use of Ciliobrevin D to inactivate dynein 1 in the testis in vivo perturbs MT organization through changes in the spatial expression of EB1, perturbs F-actin organization, and perturbs distribution of adhesion protein complexes at the BTB, leading to a loss of BTB integrity. F-actin disorganization in the seminiferous epithelium following Dync1h1 knockdown or dynein 1 inactivation by Ciliobrevin D is mediated by changes in the spatiotemporal expression of actin regulatory proteins Arp3 and Eps8[3].
In Vitro: 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].
