In Vivo

ML375 (10-30 mg/kg; i.p.; once) attenuates both the reinforcing effects and the relative strength of cocaine^[2].
ML375 exhibits low clearance (CL_p, 2.5 mL/min/kg) and a long elimination half-life (T_1/2, 80 hr) in rodents (male, Sprague-Dawley rat, 1 mg/kg IV,) and nonhuman primates (male, cynomolgus monkey, 1 mg/kg, CL_p, 3.0 mL/min/kg, T_1/2, 10 hr)^[1].
ML375 also demonstrates high oral bioavailability (%F, 80) following administration of a suspension-dose to male SD rats with a maximal plasma concentration (C_max) of 1.4 μM and a corresponding time to reach C_max (T_max) of 7 hours^[1].

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

Animal Model:

Male Sprague-Dawley rats (70 days old; 260-300 g) injected with cocaine^[2]
Dosage:

10 mg/kg, 30 mg/kg
Administration:

Result:

Produced dose-related reductions in cocaine self-administration.

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

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: ≥ 5 mg/mL (11.77 mM); Clear solution

This protocol yields a clear solution of ≥ 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 (50.0 mg/mL) to 900 μL Corn oil, 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.
