ML141 (CID-2950007) is a potent, allosteric, selective and reversible non-competitive inhibitor of Cdc42 GTPase. ML141 inhibits Cdc42 wild type and Cdc42 Q61L mutant with EC₅₀s of 2.1 and 2.6 μM, respectively. ML141 shows low micromolar potency and selectivity against other members of the Rho family of GTPases (Rac1, Rab2, Rab7). ML141 do not show cytotoxicity in multiple cell lines.

In Vitro

ML141 (CID-2950007) is not cytotoxic in either cell line at doses of 0.1-3 μM after treatment for 4 days. OVCA429 cells were insensitive to 10 μM compound, whereas some cytotoxicity was observed in SKOV3ip cells at this concentration after a 4-day treatment, although it did not reach statistical significance. ML141 is not cytotoxic toward Swiss 3T3 or Vero E6 cells up to 10 μM for 24 and 48 h, respectively^[1].
ML141 inhibits 3T3 fibroblast filopodia formation and inhibits ovarian cancer cell migration^[1].

Stock Solution Working Solution

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol 1

Add each solvent one by one: 10% DMSO 90% Corn Oil

Solubility: ≥ 2.5 mg/mL (6.14 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Protocol 2

Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline

Solubility: 2.08 mg/mL (5.10 mM); Suspended solution; Need ultrasonic

This protocol yields a suspended solution of 2.08 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

Protocol 3

Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)

Solubility: ≥ 2.08 mg/mL (5.10 mM); Clear solution

This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
