Product Introduction

Bioactivity

Description	Lopinavir (ABT-378) is a peptidomimetic HIV protease inhibitor effective against HIV protease with the Val 82 mutation. It is less affected by serum protein binding compared to the structurally related drug ritonavir.
Targets&IC50	HIV protease:1.3 pM(Ki)
In vitro	Administering Lopinavir (10 mg/kg, p.o.) to rats resulted in a maximum concentration (Cmax) of 0.8 μg/mL, with the drug's bioavailability being 25%.
In vivo	Lopinavir is an effective inhibitor of Rh123, with an IC50 value of 1.7 mM for Caco-2 cell monolayers. It binds to mutant HIV proteases (V82A, V82T, and V82F) with Ki values of 4.9, 3.7, and 3.6 pM, respectively. At a concentration of 0.5 nM, Lopinavir inhibits the activity of wild-type HIV protease by 93%. It also inhibits HIV protease activity in MT4 cells both in the presence and absence of 50% HS, with EC50 values of 102 nM and 17 nM, respectively. In liver microsomes, Lopinavir is converted to primary metabolites M-3 and M-4, a process that is NADPH-dependent. After treating LS 180V cells with Lopinavir for 72 hours, there is a reduction in intracellular Rh123 content and induction of P-glycoprotein immunoreactive protein and mRNA levels. Lopinavir exhibits an IC50 of 9.4 nM against subtype C clone C6. When acting on human liver microsomes, Lopinavir shows an IC50 of 7.3 mM against CYP3A and exerts weak inhibition on human CYP1A2, 2B6, 2C9, 2C19, and 2D6.

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the stock solution preparation method and in vivo formula preparation method:

For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, TargetMol | Animal experiments

and a total of 10 animals are to be administered, using a formulation of TargetMol | reagent

10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH₂O , the resulting working solution concentration would be 2 mg/mL.

Stock Solution Preparation:

Dissolve 2 mg of the compound in 100 μL DMSO TargetMol | reagent to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.

Preparation of the In Vivo Formulation:

1) Add 100 μL of the DMSO TargetMol | reagent stock solution to 400 μL PEG300 and mix thoroughly until the solution becomes clear.

2) Add 50 μL Tween 80 and mix well until fully clarified.

3) Add 450 μL Saline,PBS or ddH₂O TargetMol | reagent and mix thoroughly until a homogeneous solution is obtained.

This example is provided solely to demonstrate the use of the In Vivo Formulation Calculator and does not constitute a recommended formulation for any specific compound. Please select an appropriate dissolution and formulation strategy based on your experimental model and route of administration.

All co-solvents required for this protocol, includingDMSO, PEG300/PEG400, Tween 80, SBE-β-CD, and Corn oil, are available for purchase on the TargetMol website.
