EHop-016
目录号 : GC10030A Rac1 and Rac3 inhibitor
Cas No.:1380432-32-5
Sample solution is provided at 25 µL, 10mM.
EHop-016 is a novel and specific inhibitor of Rac1 and Rac3 activity (IC50= 1.1 μm).
Rac is a member of the RAS superfamily of small GTPase. It functions in various cellular processes including regulation of secretory processes, membrane ruffles, cell polarization and phagocytosis of apoptotic cells etc. It is contributed to malignant progression.
Ehop-016 inhibited Rac activity in metastatic cancer cell MDA-MB-435 which overexpressed Rac and inhibited high endogenous Rac activity as well. In metastatic breast cancer cell MDA-MB-231, Ehop-016 blocked the Rac activity and reduced Rac-mediated lamelipodia formation. It also attenuated the effects of Rac downstream protein p21-activated kinase 1 and directed migration of metastatic cancer cells. [1]
In C3H/HeJ mice carrying KITD814V following overnight treatment of 2.5 μM EHop-016 or 25 μM NSC23766, EHop-016 reduced spleen size and PB counts thus significantly promoted the survival of leukemic mice compared with NSC23766. [2]

Rac Activity Assays |
Rac activity is determined from lysates of the MDA-MB-435 and MDA-MB-231 human metastatic cancer cell lines. Cancer cells in culture medium (DMEM, 10% FBS, pH 7.5) are treated with vehicle (0.1% DMSO) or varying concentrations of EHop-016 (0–10 μM) for 24 h. Rac1 activity is determined using the G-LISA Rac1 activation assay kit. |

Preparation method |
The solubility of this compound in DMSO is >10 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 |
0–10 μM for 24 h |
Applications |
EHop-016 inhibited Rac activity and reduced Rac-directed lamellipodia formation in both MDA-MB-435 and MDA-MB-231 metastatic cancer cells. Moreover, EHop-016 decreased Rac downstream effects of PAK1 (p21-activated kinase 1) activity and directed metastatic cancer cells migration. |

Dosage form |
2.5 μM; i.v. injection, for 45 days; |
Applications |
Treatment of KITD814V-bearing cells with EHop-016 significantly enhanced leukemic mice survival and delayed disease progression. |
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. |
