Lopinavir is a potent HIV protease inhibitor with Ki of 1.3 pM in a cell-free assay.
1 Customer Review
Low-micromolar amounts of chloroquine, chlorpromazine, loperamide, and lopinavir inhibit MERS-CoV-induced cytopathology. Huh7 cells in 96-well plates were infected with MERS-CoV isolate EMC/2012 (MOI, 0.005) in the presence of 0 to 20 uM LPV. Cells were incubated for 2 days, and cell viability was monitored using an MTS assay. In addition, the potential toxicity of compound treatment only was monitored in parallel mock-infected Huh7 cell cultures. Graphs show the results (averages and standard deviations [SD]) of a representative experiment that was performed in quadruplicate. All experiments were repeated at least twice. For each compound, the calculated EC50, CC50, and SI values are given.

|Description||Lopinavir is a potent HIV protease inhibitor with Ki of 1.3 pM in a cell-free assay.|
Lopinavir binds to mutant HIV protease (V82A, V82F and V82T) with Ki of 4.9 pM, 3.7 pM and 3.6 pM, respectively. Lopinavir inhibits 93% of wild-type HIV protease activity at 0.5 nM. Lopinavir inhibits HIV protease activity in the absence and presence of 50% HS with EC50 of 17 nM and 102 nM, respectively, in MT4 cells.  Lopinavir is converted to several metabolites in an NADPH-dependent manner in liver microsomes with the primary metabolites M-3 and M-4.  Lopinavir is a potent inhibitor of Rh123 efflux in Caco-2 monolayers with IC50 of 1.7 mM. Lopinavir exposure (72 hours) in LS 180V cells reduces the content of intracellular Rh123. Lopinavir induces P-glycoprotein immunoreactive protein and messenger RNA levels in LS 180V cells.  Lopinavir inhibits subtype C clone C6 with IC50 of 9.4 nM.  Lopinavir inhibits CYP3A with IC50 of 7.3 mM in human liver microsomes, while produces negligible or weak inhibition of human CYP1A2, 2B6, 2C9, 2C19 and 2D6. 
|In vivo||Lopinavir (10 mg/kg, orally) results in Cmax of 0.8 μg/mL and oral bioavailability of 25% in rats. |

* 1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
