| Cell experiment [1]: | |
|
Cell lines |
3T3-L1 preadipocytes |
|
Preparation method |
The solubility of this compound in ethanol is 25 mM. General tips for obtaining a higher concentration: Please warm the tube at 37℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months. |
|
Reacting condition |
2.5, 5, and 10 μM |
|
Applications |
In 3T3-L1 preadipocytes, radicicol dose-dependently reduced intracellular lipids, resulting in significantly lower lipid contents. Radicicol significantly decreased the protein expression of PPARγand C/EBPα protein, which then affected adipocyte differentiation. |
| Animal experiment [2]: | |
|
Animal models |
Male C57BL/6 mice |
|
Dosage form |
60 mg/kg; diluted in vehicle (PBS) |
|
Application |
In male C57BL/6 mice, radicicol (60 mg/kg) reduced cecal ligation and puncture (CLP)-induced leukocyte rolling by 15% and adhesion by 22%. In these septic mice, radicicol decreased CLP-induced MPO levels in the colon by 24%. Pretreatment with radicicol decreased CLP-evoked formation of MIP-2 and KC down to 68.4 ± 10.5 ng/g and 96.7 ± 15.2 ng/g, respectively, in the colon. |
|
Other notes |
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |

Radicicol is an inhibitor of the ATPase/kinase with IC50 values of ＜1μM, 100μM and 400μM, respectively for Hsp90, Topo VI and PDK3 [1].
Radicicol inhibits the activities of Hsp90, Topo VI and PDK3 by blocking ATP binding to them. Radicicol binds to the ATP-binding site in the C-terminal domain of PDK3 and competes with ATP. The inhibition does not cause the structure change of PDK3. Radicicol also shows a weak inhibition of PDK1 and PDK2 with IC50 value of 230mM and Ki value of 23μM, respectively [1].
As an inhibitor of Hsp90, radicicol is reported to downregulate the expression of PPARγ, C/EBPα , FAS and FABP4 results in the inhibition of lipid accumulation in 3T3-L1 adipocytes. Radicicol also has effects on cell cycle arrest and the PDK1/Akt pathway, thus causing the inhibition of the differentiation of 3T3-L1 preadipocytes. In addition, it is shown that radicicol increases the activation of the caspase-8- and Bid-dependent pathway and then enhances TRAIL-induced apoptosis in ovarian carcinoma cell lines [2, 3].
