    • Alomone Labs Quin-C7 partially inhibits FPR2 activation in HL-60 cells.
      Alomone Labs Quin-C7 partially inhibits FPR2 activation in HL-60 cells.
      Non-differentiated HL-60 human acute promyelocytic leukemia cells were loaded with Fluo-3 AM. Changes in intracellular Ca2+ were detected as changes in Fluo-3 emission following stimulation. Normalized fluorescence is shown before and after application (arrow) of 10 nM FPR agonist WKYMVm (#GPW-105) in absence (top trace) or in presence of 100 µM Quin-C7 (#Q-155) (middle trace), compared to baseline (bottom trace).

    Scientific background

    Quin-C7 is a synthetic quinazolinone derivative that acts as a nonpeptide antagonist of human formyl peptide receptor like 1 (FPRL1, FPR2)1. Quin-C7 can partially displace [(125)I]Trp-Lys-Tyr-Met-Val-d-Met-NH(2) (WKYMVm) binding to FPRL1 receptor1.

    The formyl peptide receptors include the FPR1, FPR2, and FPR3. FPR2 is primarily expressed in neutrophils and monocytes where it plays an important role in inflammation and in the immune system1,2.
