A 14-aa internally disulfide-bonded peptide that potently competes against SDF-1alpha/CXCL12 for CXCR4 binding (IC50 = 0.91nM; [SDF-1] = 100nM) and protects MT-4 cells against X4-HIV strain HIV-1IIIB infection (EC50 = 4nM in 5 d; MOI = 0.01) with no significant cytotoxicity (CC50 = 56uM; 5 d). Inhibits SDF-1-induced Ca2+ mobilization (IC50 = 4.5nM; [SDF-1] = 30nM; CXCR4-expressing CHO cells) in vitro and effectively prevents CXCR4-dependent 5BC-5 metastasis in NK-depleted SCID mice in vivo (10mg/kg i.p.) in vivo.Formula:C101H145FN34O18S2.xH2OSequence:N alpha-4-fluorobenzoyl-Arg-Arg-Nal-Cys4-Tyr-Cit-Lys-D-Lys-Pro-Tyr-Arg-Cit-Cys¹3-Arg-NH2 (Disulfide bond: 4 → 13; Nal = L-3-(2-naphthyl)alanine; Cit = L-citrulline)Solubility:H2OPrimary Target:CXCR4Primary Target IC50:0.9nMMolar Mass:2206.58Storage and Stability:Lyophilized powder may be stored at -20°C.
