Home Cell Cycle Rho inhibitor - p38 MAPK activator - Apoptosis related modulator ML141 For research use only.

ML141

Synonyms: CID-2950007

ML141 (CID-2950007) is demonstrated to be a potent, selective and reversible non-competitive inhibitor of Cdc42 GTPase suitable for in vitro assays, with IC50 of 200 nM and selectivity against other members of the Rho family of GTPases (Rac1, Rab2, Rab7). ML141 is associated with an increase in p38 activation and may induce p38-dependent apoptosis/senescence. ML141 also protects neuroblastoma cells from metformin-induced apoptosis.

Biological Activity

Description ML141 (CID-2950007) is demonstrated to be a potent, selective and reversible non-competitive inhibitor of Cdc42 GTPase suitable for in vitro assays, with IC50 of 200 nM and selectivity against other members of the Rho family of GTPases (Rac1, Rab2, Rab7). ML141 is associated with an increase in p38 activation and may induce p38-dependent apoptosis/senescence. ML141 also protects neuroblastoma cells from metformin-induced apoptosis.
Targets
cdc42 [1]
200 nM
In vitro
In vitro ML141 enhances the ability of TMX to suppress BLBC cell growth through both induction of cell death and suppression of cell division. [2] ML141 also significantly protects neuroblastoma cells from metformin-induced apoptosis. [3] Moreover, ML141 diminishes K. pneumoniae invasion in a dose-dependent manner. [4]
Kinase Assay Equilibrium binding assay
Wild-type GST-Cdc42 (4 μM) is bound to GSH-beads overnight at 4°C. Cdc42 on GSH-beads is depleted of nucleotide by incubating with 10 mM EDTA containing buffer for 20 min at 30°C, washing twice with NP- HPS buffer, then re-suspended in the same buffer containing 1 mM EDTA/or 1 mM MgCl2, 1 mM DTT and 0.1% BSA. Cdc42 unbound sites are blocked by incubation of protein–bead complex for 15 min at RT. Thirty μL of this suspension is incubated with 20 mM inhibitor for 3 min at RT and added 30 μL of various concentrations of ice cold BODIPY-FL-GTP. Samples incubated at 4° C for 45 min and binding of fluorescent nucleotide to enzyme is measured using an Accuri flow cytometer. Raw data are exported and plotted using GraphPad Prism software.
Cell Research Cell lines Basal-B (MDA-MB 231 and HCC38) and Basal-A with HER2 amplification (HCC1954) cells
Concentrations ~20 μM
Incubation Time 48 hours
Method

Cells are incubated with 500 nM Calcein-AM and 1 µM PI for 15 min, after which live cells and dead cells (represented by positivity of Calcein-AM and PI staining, respectively) are counted utilizing the adherent cell Celigo™ cytometer.

In Vivo
In vivo In NOD/SCID mice bearing MDA-MB 231 derived tumors, ML141 (1 mg/day i.p.), via inhibition of Cdc42, enables TMX to suppress growth of MDA-MB 231 derived tumors. [2] In addition, ML141 (10 mg/kg i.p.) enhances G-CSF-induced hematopoietic stem and progenitor cell mobilization in mice. [5]

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.
