PBP10 TFA is a cell-permeable formyl peptide receptor 2 (FPR2) antagonist[1-2]. PBP10 TFA exhibits multiple biological activities, including antibacterial, antiviral, and cancer-inhibitory effects[3-4].
In vitro, pretreatment of human keratinocytes (HaCaT) with PBP10 TFA (2-10μg/mL) for 20 minutes significantly suppresses the release of pro-inflammatory mediators such as nitric oxide (NO), reactive oxygen species (ROS), and interleukin-8 (IL-8) induced by stimulation with lipopolysaccharide (LPS; 1μg/mL) or lipoteichoic acid (LTA; 1μg/mL), while also reversing inflammation-related nanomechanical changes, such as the reduction in cell stiffness caused by LPS[5]. Pretreatment of RT4 Schwann cells with PBP10 TFA (1 μM) for 20 minutes, followed by stimulation with fMLF (10nM–100nM) for 6 hours, significantly inhibits fMLF-induced upregulation of Fpr2 protein expression and the decrease in p-NFκB levels, while also reversing changes in the expression of CCR2, CXCR4, and PKCβ[6].

| Cell experiment [1]: | |
Cell lines | HaCaT cells (human immortalized keratinocyte cell line) |
Preparation Method | HaCaT cells were maintained in high-glucose Dulbecco’s Modified Eagle Medium (DMEM) supplemented with 10% fetal bovine serum (FBS), 2mM L-glutamine, and antibiotics (50U/mL penicillin, 50µg/mL streptomycin) at 37°C, 5% CO₂. Cells were pretreated with PBP10 TFA (2–10µg/mL) for 20 min, followed by stimulation with bacterial lipopolysaccharide (LPS; 1µg/mL) or lipoteichoic acid (LTA; 1µg/mL) for 24h in serum-free conditions. |
Reaction Conditions | 2–10µg/mL; pretreatment for 20min |
Applications | PBP10 TFA significantly suppressed LPS/LTA-induced production of inflammatory mediators, including nitric oxide (NO), reactive oxygen species (ROS), and interleukin-8 (IL-8), in a dose-dependent manner. PBP10 TFA also reversed LPS-induced softening of cell stiffness, as measured by atomic force microscopy (AFM), indicating restoration of cytoskeletal integrity. |
