Clear solution	5% DMSO 1 95% Corn oil	0.25mg/ml	Taking the 1 mL working solution as an example, add 50 μL of 5 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results.
Clear solution	5%DMSO 1 40%PEG300 2 5%Tween80 3 50%ddH2O	1.0mg/ml	Taking the 1 mL working solution as an example, add 50 μL of 20 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results.

* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description

Ciliobrevin D (compound 5) is a cell-permeable, reversible and specific antagonist of AAA+ (ATPases associated with diverse cellular activities) ATPase motor cytoplasmic dynein. Ciliobrevin D perturbs primary cilia formation and blocks Hedgehog (Hh) signaling.

Targets

cytoplasmic dynein ^[1]

Hedgehog ^[1]

In vitro

Ciliobrevin D inactivate dynein in Sertoli cells. The inactivation of dynein by ciliobrevin D also perturbs gross disruption of F-actin across the Sertoli cells in vitro.^[2] Ciliobrevin D perturbs protein trafficking within the primary cilium, leading to their malformation and Hedgehog signaling blockade. Ciliobrevin D also prevents spindle pole focusing, kinetochore-microtubule attachment, melanosome aggregation, and peroxisome motility in cultured cells.^[1]

In vivo

Ciliobrevin D inactivate dynein in the testis. The inactivation of dynein by ciliobrevin D also perturbs gross disruption of F-actin across the seminiferous epithelium in vivo, illustrating there are cross talks between the two cytoskeletons in the testis.^[2]

Protocol (from reference)

Cell Assay:^{^[2]}	Cell lines Sertoli cells Concentrations 15 µM, 30 µM Incubation Time 1 h Method Sertoli cells cultured in vitro on Matrigel-coated bicameral units at 1.0 × 10⁶ cells/cm² are used for quantifying the transepithelial electrical resistance in ohms (Ω) across the cell epithelium to assess the TJ-barrier function. In brief, each bicameral unit is placed inside the well of a 24-well dish with 0.5 ml F12/DMEM in the apical and the basal compartments. Dynein is inhibited in Sertoli cells on days 3 and 4 using Ciliobrevin D at 15 µM or 30 µM for 1hr, and Sertoli cell TJ-permeability barrier function is monitored daily by quantifying transepithelial electrical resistance across the cell epithelium.
