ALX 40-4C (Trifluoroacetate)

ALX 40-4C Trifluoroacetate is a small peptide inhibitor of the chemokine receptor CXCR4, inhibits SDF-1 from binding CXCR4 with a Ki of 1 μM, and suppresses the replication of X4 strains of HIV-1; ALX 40-4C Trifluoroacetate also acts as an antagonist of the APJ receptor, with an IC50 of 2.9 μM.
