Descrição

Descrição geral

A cell-permeable, orally available, and metabolically stable macrocyclic hexapeptidomimetic compound that acts as a non-competitive antagonist of complement C5a receptor (C5aR; CD88; IC₅₀ = 240 nM) and as a low-affinity agonist for MrgX2, a GPCR, in human mast cells Shown to specifically bind to C5aR1 and not to CaR2 and C3aR. Displays a broad range of anti-inflammatory effects, both in vitro and in vivo. Shown to inhibit C5a-induced neutrophil myeloperoxidase release (IC₅₀ = 22 nM) and chemotaxis (IC₅₀ = 75 nM). Preincubation with PMX-53 (~10 nM) blocks C5a-induced Ca2+ responses in HMC-1 and RBL-2H3 cells, but does not affect C3a responses. Suppresses the growth of 4T1 mammary carcinoma tumor xenograft in mice (1 mg/kg/every 2-3 days, s.c.). Reported to diminish C5a-mediated increase in pluripotency in human embryonic stem cells in the absence of FGF2.
