Biological Activity

Description R-IMPP is an inhibitor of PCSK9 secretion, half maximal inhibitory concentration [IC50] = 4.8 μM.
Targets
PCSK9 [1]
In vitro R-IMPP promotes uptake of LDL-C in hepatoma cells by increasing LDL-R levels, without altering levels of secreted transferrin. R-IMPP does not decrease PCSK9 transcription or increase PCSK9 degradation, but instead causes transcript-dependent inhibition of PCSK9 translation. R-IMPP is discovered that exhibited weak PCSK9 anti-secretagogue activity (half maximal inhibitory concentration [IC50] = 4.8 μM), but does not affect intracellular ATP levels in the recombinant CHO-K1 cells, a measure of cytotoxicity, nor decrease secretion of a control protein, secreted alkaline phosphatase, a measure of relative selectivity. The inhibitory response of R-IMPP is stereospecific[1].

Protocol (from reference)

Cell Assay:

[1]

  • Cell lines

    Huh7 cells

  • Concentrations

    10, 30 μM

  • Incubation Time

    24 h

  • Method

    Huh7 cells are plated at 150,000 cells per well and transfected with the full-length and truncation mutants. After 24 hr, cells are treated with vehicle, 30 μMR-IMPP, or 30 μM S-IMPP. At 48 hr post-transfection, cells are washed three times with TBS +2 mg/mL BSA and lysed with 100 mL of RIPA buffer per well. Protein lysates are subjected to SDS-PAGE and western blot analysis for PCSK9 (V5) and b-actin.
