Biological Activity

Description

CU-CPT9a is a potent and specific antagonist of Toll-like receptor 8 (TLR8) with IC50 of 0.5 nM.

Targets
TLR8 [1]
(Cell-free assay)
0.5 nM
In vitro

PBMC treatment with R848 or RNA-40 induces IL-6 production, and this activation is suppressed by CU-CPT9a in a dose-dependent manner. A dose-dependent suppression of IL-6 production by CU-CPT9a is also observed when cells are stimulated with violacein. Previous addition of CU-CPT9a only blocks IL-1β stimulated by R848 and has no effect on violacein-induced IL-1β stimulation.[2]

Protocol (from reference)

Cell Research:

[2]

  • Cell lines: Human PBMCs
  • Concentrations: 0.02 μmol/L, 0.2 μmol/L, 2 μmol/L, 20 μmol/L
  • Incubation Time: 1 h
  • Method:

    Human PBMCs are cultured (50 μL of 6 × 106 live cells/mL) in a 96-well plate. Cells are treated with different concentrations of CU-CPT9a (0.02, 0.2, 2 and 20 μmol/L) or medium as a negative control and are incubated for 1 h at 37 °C, 5% CO2. After this, cells are treated with violacein (30 and 15 μmol/L), R848 (1 μmol/L), LPS (50 ng/mL) or RNA-40 (5 μg/mL). After incubating for 20 h, the culture supernatants are collected and used to measure the concentration of IL-6 or IL-1β by ELISA according to the manufacturer’s instructions.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
