Description Dalcetrapib, a rhCETP inhibitor (IC50=0.2 μM), increases the plasma HDL cholesterol.
Targets&IC50 rhCETP:0.2 μM
In vitro Dalcetrapib modulates CETP activity. Dalcetrapib induces a conformational change in CETP, when added to human plasma. CETP-induced pre-β-HDL formation in human plasma is unchanged by Dalcetrapib ≤3 μM and increased at 10 μM. Dalcetrapib statistically and significantly increases pre-β-HDL formation. [1] Dalcetrapib achieves 50% inhibition of CETP activity in human plasma at a concentration of 9 μM. [2] Dalcetrapib inhibits the CETP activity of media in HepG2 in a dose-dependent manner. [3]
In vivo Treatment with Dalcetrapib leads to significant increases in HDL-C levels. In hamsters injected with [3H]cholesterol-labeled autologous macrophages Dalcetrapib significantly increases fecal elimination of both [3H]neutral sterols and [3H]bile acids. Dalcetrapib increases plasma HDL-[3H]cholesterol. [1] Dalcetrapib has 95% inhibition of CETP activity in male Japanese white rabbits at an oral dose of 30 mg/kg. Dalcetrapib increases the plasma HDL cholesterol level by 27% and 54%, respectively, when given at oral doses of 30 mg/kg or 100 mg/kg once a day for 3 days to male Japanese white rabbits. [2] Treatment with Dalcetrapib markedly increases serum levels of HDL-C. The ratio of HDL2-C to HDL3-C is significantly higher in Dalcetrapib–treated rabbits than in control rabbits at 5 and 7 months, indicating that the inhibition of CETP activity by Dalcetrapib changes the distribution of HDL subfractions and preferentially increases HDL2-C levels. Dalcetrapib treatment increases serum paraoxonase activity and HDL-associated platelet-activating factor acetylhydrolase activity, but decreases the plasma lysophosphatidylcholine concentration. [4]
Kinase Assay Inhibition of rhCETP and C13S CETP-mediated transfer of CE from HDL to LDL: The inhibitory potency (IC50) of Dalcetrapib to decrease CE transfer from HDL to LDL by rhCETP and C13S CETP is measured using a scintillation proximity assay kit. Briefly, [3H]CE-labeled HDL donor particles are incubated in the presence of purified CETP proteins (final concentration 0.5 μg/mL) and biotinylated LDL acceptor particles for 3 hours at 37 °C. Subsequently, streptavidin-coupled polyvinyltoluene beads containing liquid scintillation cocktail binding selectively to biotinylated LDL are added, and the amount of [3H]CE molecules transferred to LDL is measured by β counting.
Cell Research The HepG2 cells are seeded in 6-well plates and cultured to 70–80% confluence. After being washed with PBS, the cells are incubated with growth medium and a different concentration (0 μM–30 μM) of chemical inhibitor Dalcetrapib and dissolved in 2% DMSO for 24 hours. Total RNA is used for RT-PCR.(Only for Reference)

  • Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Concentration of a solution resulting from a known mass of compound in a specific volume
See Example

An example of a molarity calculation using the molarity calculator
What is the mass of compound required to make a 10 mM stock solution in 10 ml of water given that the molecular weight of the compound is 197.13 g/mol?
Enter 197.13 into the Molecular Weight (MW) box
Enter 10 into the Concentration box and select the correct unit (millimolar)
Enter 10 into the Volume box and select the correct unit (milliliter)
Press calculate
The answer of 19.713 mg appears in the Mass box

Calculate the dilution required to prepare a stock solution
The dilution calculator is a useful tool which allows you to calculate how to dilute a stock solution of known concentration. Enter C1, C2 & V2 to calculate V1.

See Example

An example of a dilution calculation using the Tocris dilution calculator
What volume of a given 10 mM stock solution is required to make 20ml of a 50 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=50 μM, V2=20 ml and V1 is the unknown:
Enter 10 into the Concentration (start) box and select the correct unit (millimolar)
Enter 50 into the Concentration (final) box and select the correct unit (micromolar)
Enter 20 into the Volume (final) box and select the correct unit (milliliter)
Press calculate
The answer of 100 microliter (0.1 ml) appears in the Volume (start) box
