Biological Activity

Description ZCL278 is a selective Cdc42 GTPase inhibitor with Kd of 11.4 μM.
Cdc42 GTPase [1]
11.4 μM(Kd)
In vitro

ZCL278 inhibits Cdc42 GTPase activity by the competition with GTP and inhibits Rac/Cdc42 phosphorylation in a time-dependent manner. ZCL278 (50 μM) inhibits Cdc42-mediated microspike formation and disrupts GM130-docked Golgi structures in serum-starved Swiss 3T3 fibroblasts. In addition, ZCL278 also suppresses Cdc42-mediated neuronal branching and growth cone dynamics as well as actin-based motility and migration in a metastatic prostate cancer PC-3 cell line without cytotoxicity.

Working concentration: mg/ml;

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.
