      A cell-permeable, orally active, non-toxic, cyclobutenedione compound with anti-inflammatory properties. Acts as a specific, high-affinity, and potent allosteric antagonist of CXCR2 (IC50 = 2.6 nM for human; Kd = 49, 200, and 80 pM for human, rat, and cynomolgus, respectively). Also exhibits high potency against CXCR1 (IC50 = 36 nM for human, Kd = 3.9 and 41 nM for human and cynomolgus, respectively). Displays excellent selectivity over CXCR3, CCR5, and a large panel of GPCRs, enzymes and ion channels (~ 10 µM). Potently inhibits CXCL1- and CXCL8-induced chemotaxis in human neutrophils (hPMN; IC50 < 1 nM and 16 nM, respectively). Shown to suppress pulmonary neutrophilia (ED50 = 1.3 mg/kg), goblet cell hyperplasia (ED50 = 700 mg/kg), and increase bronchoalveolar lavage (BAL) mucin content (ED50 ≤ 1 mg/kg) in rats subjected to vanadium pentoxide induced pulmonary inflammation. Inhibits melanoma cell proliferation (~ 1 mg/ml) by suppressing the phosphorylation of ERK1/2. Diminishes the invasive potential of melanoma cells and blocks angiogenesis in mice (100 mg/kg, p.o., q.d for 21 days). Exhibits desirable pharmacokinetic properties.

      Please note that the molecular weight for this compound is batch-specific due to variable water content.

      DescriptionA cell-permeable orally available (plasma Cmax/AUC/dose = 17.0 µM/31.5 µM h-10-24 h/25 mg kg-1/mouse; 5.0 µM/23.0 µM h-10-48 h/10 mg kg-1/rat; 0.9 µM/4.0 µM h-10-48 h/3 mg kg-1/Cynomolgus monkey) cyclobutenedione compound that targets CXCR2 intracellular allosteric site via high affinity interaction (Kd = 49 pM/human, 80 pM/Cynomolgus monkey, 200 pM/ mouse & rat) in a reversible and slowly dissociating manner (k2 = 0.00058 min-1; t1/2 ≈ 22 h; human CXCR2), while exhibiting much reduced affinity toward CXCR1 (Kd = 3.9 nM/human & 41 nM/Cynomolgus monkey) due to a much faster dissociation rate (k2 = 0.141 min-1; t1/2 ≈ 5 min; human CXCR1) and displaying no significant efficacy toward a large panel of GPCRs, enzymes, and ion channels (IC50 >10 µM), including CXCR3 & CCR5. Likewise, Sch527123 is shown exhibit much higher potency against CXCR2- than CXCR1-mediated chemotaxis of Ba/F3 transfectants (IC50/ligand/CXCR2 species = 2.8 nM/3 nM hCXCL8/monkey, 3.4 nM/3 nM rCINC-3/rat, 5.6 nM/mCXCR2/3 nM mMIP-2, <<3 nM/0.1 to 60 nM hCXCL8/human; % inhibition/[Sch527123]/ligand/CXCR1 species = 35%/300 nM/3 nM hCXCL8/ human & 50%/9.667 µM/3 nM hCXCL8/monkey) without affecting C5a- or fMLP-induced human neutrophil chemotaxis. Oral administration is shown to effectively reduce pulmonary neutrophilia in vivo among LPS- or V2O5-treated mice & rats (ED50 1.3 to 1.8 mg/kg), as well as among Cynomolgus monkeys receiving repeat bronchoscopy & lung lavage (ED50 0.3 mg/kg). Also reported to inhibit hCXCL8-dependent human melanoma A375SM chemotaxis & invasion (79% & 69% inhibition, respectively, with 10 ng/mL = 25 nM Sch527123; overnight at 37 °C;10 ng/mL hCXCL8) and effectively suppress A375SM proliferation both in cultures in vitro (31% inhibition by MTT assay post 72 h treatment with 1 µg/mL = 2.5 µM Sch527123) and in mice in vivo (79% inhibition on D50 post cancer cells injection; 100 mg/kg/d p.o. D1 through D22) with concomitant increased apoptotic cells (203% of control) and decreased microvessel density in tumor tissues (55% of control).
