| Name | ML141 |
| Description | ML141 (CID-2950007) is an effective, specific and reversible non-competitive inhibitor of Rho family GTPase cdc42 (IC50: 200 nM). |
| Cell Research | 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. (Only for Reference) |
| 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. |
| In vitro | In NOD/SCID mice carrying MDA-MB 231-derived tumors, ML141 (1 mg/day, intraperitoneally) inhibits the growth of these tumors by suppressing Cdc42, thereby enhancing the effectiveness of TMX. Additionally, ML141 (10 mg/kg, intraperitoneally) increases the mobilization of hematopoietic stem and progenitor cells induced by granulocyte colony-stimulating factors. |
| In vivo | ML141 significantly protects against apoptosis damage induced by metformin in neuroblastoma. It enhances the ability of caffeine to inhibit cell growth through the induction/suppression of cell death/division. Additionally, ML141 dose-dependently reduces the invasion of Klebsiella pneumoniae. |
| Storage | Powder: -20°C for 3 years | In solvent: -80°C for 1 year | Shipping with blue ice. |
| Solubility Information | DMSO : 65 mg/mL (159.51 mM)
