  3. ML218

ML218 is a potent, selective and orally active T-type Ca2+ channels (Cav3.1, Cav3.2, Cav3.3) inhibitor with IC50s of 310 nM and 270 nM for Cav3.2 and Cav3.3, respectively. ML218 inhibits the burst activity in subthalamic nucleus (STN) neurons. ML218 has no significant inhibition of L- or N-type calcium channels, KATP or hERG potassium channels.

Description

ML218 is a potent, selective and orally active T-type Ca2+ channels (Cav3.1, Cav3.2, Cav3.3) inhibitor with IC50s of 310 nM and 270 nM for Cav3.2 and Cav3.3, respectively. ML218 inhibits the burst activity in subthalamic nucleus (STN) neurons. ML218 has no significant inhibition of L- or N-type calcium channels, KATP or hERG potassium channels. ML218 can penetrate the blood-brain barrier[1].

IC50 & Target

T-type calcium channel

 

In Vitro

In plasma protein binding studies (equilibrium dialysis), ML218 possesses good free fraction in both rat and human. Intrinsic clearance experiments in liver microsomes indicated that ML218 is highly cleared in rat (CLint = 115 mL/min/kg), but low to moderately cleared in human liver microsomes (CLint = 12.7 mL/min/kg)[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

ML218 (0.03-30 mg/kg; oral administration; once; male Sprague-Dawley rats) treatment reverses cataleptic behavior in rats induced by a 0.75 mg/kg dose of haloperidol[1].
Free brain and plasma concentrations of ML218 increases in a dose proportional manner across the dose range (3 mg/kg: [plasma] = 98 nM, [brain] = 1.66 μM; 10 mg/kg: [plasma] = 282 nM, [brain] = 5.03 μM; 30 mg/kg: 1.2 μM, [brain] = 17.7 μM)[1].
Noncompartmental pharmacokinetic analysis indicates ML218 (1 mg/kg, IV) has a mean residence time (MRT) of nearly 7 h, a value which is consistent with its terminal half-life (t1/2 = 7 h)[1].

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

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: ≥ 6.25 mg/mL (16.92 mM); Clear solution

    This protocol yields a clear solution of ≥ 6.25 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 (62.5 mg/mL) to 900 μL Corn oil, and mix evenly.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
