Biological Activity

Description Rhosin (G04) hydrochloride (HCl) is a potent, specific inhibitor of RhoA subfamily Rho GTPases with Kd of ~ 0.4 uM. Rhosin hydrochloride induces cell apoptosis.

0.4 μM(Kd)
In vitro
In vitro

In cells Rhosin specifically inhibits RhoA activity and RhoA-mediated cellular function without affecting Cdc42 or Rac1 signaling activities. By suppressing RhoA or RhoC activity Rhosin can inhibit mammary sphere formation by breast cancer cells, suppress invasion of mammary epithelial cells, and induce neurite outgrowth of PC12 cells in synergy with NGF.[1]
Cell Research Cell lines NIH3T3 cells, MCF7 cells, HME cells
Concentrations 10 μM, 30 μM, 50 μM
Incubation Time 24 h
Method

NIH3T3 cells, MCF7 cells, or HME cells are grown in log phase in a 10-cm dish or a sixwell dish, and are starved in serum-free medium in the presence or absence of G04 at indicated concentrations for 24 hours and are subsequently stimulated with 10% calf serum or fetal bovine serum for 15 min. Cells are lysed in a buffer containing 20 mM Tris-HCL, pH 7.6, 100 mM NaCl, 1% Triton X-100, 10 mM MgCl2, 2 mM NaF and protease inhibitors (2 mM PMSF, 10 μg/ml leupeptin, 10 μg/ml aprotinin). Lysates are clarified, the protein concentrations are normalized, and the GTP-bound RhoA, Rac1 or Cdc42 in the lysates are measured by respective anti-RhoA, Rac1 and Cdc42 Western blotting of the effector domain pull-downs.

In vivo

Treatment with rhosin abrogates the lung metastasis of B16BL6 and 4T1 cells in vivo.[2]

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
