Biological Activity
ML141(CID-2950007) is a potent, selective and reversible non-competitive inhibitor of Cdc42 GTPase(IC50=200 nM) with low micromolar potency and selectivity against other members of the Rho family of GTPases (Rac1, Rab2, Rab7).
In Vitro
In the primary HTS bead-based assay using 1 mM EDTA and 100 nM BODIPY-FL-GTP, potency for CID2950007 was IC50 = 2.6 and 5.4 μM for Cdc42 wild type and activated mutant, respectively [1]. ML141 exposure also enhanced the ability of TMX to suppress BLBC cell growth, through both induction of cell death and suppression of cell division [2].
In Vivo
Treatment with ML141 + TMX caused a suppression of further tumour growth in vivo [2]. Parallel suppression of the conserved brain CDC42 activity by intracerebroventricular ML141 injection caused acute anxiety in mice [3]. using a pilocarpine-induced epileptic model, we found that pretreatment with ML141, a specific inhibitor of Cdc42, reduces seizure severity [4].
