Cas No.:473719-41-4
Sample solution is provided at 25 µL, 10mM.
AMG 487 is an oral, selective chemokine receptor 3 (CXCR3) antagonist that inhibits CXCL10 and CXCL11 binding to CXCR3 with IC50 values of 8.0 and 8.2 nM, respectively[1].
AMG 487(1 µM AMG 487;18 h (C26 cells) or 40 h (HT29 cells)), the CXCR3 antagonist, significantly inhibited the migratory responses of the cells to each of the three ligands(rCXCL9, rCXCL10 and rCXCL11)[2].
the AMG 487-treated mice(SCID mice:1 µM AMG 487;s.c.7-17day. Balb/c mice:5 mg/kg: s.c.˙twice daily.) exhibited fewer pulmonary nodules than the control mice in both the models: a 62% reduction in the human mode and 42% less nodules in the mouse model. The inhibitory effect of AMG 487 treatment was also detectable in the cumulative tumour volume with a reduction by 58% in the lungs of the HT29-injected immunodeficient mice and by 51% in the lungs of the C26-injected syngeneic mice[2]. During in vitro differentiation, the addition of AMG 487(3- 60µM) decreased the expression of DC co-stimulatory markers, indicating that DC was in a semi-mature state[4]. 66.1 tumor cells were pretreated with AMG 487 prior to i.v. injection into immune-competent female mice. Antagonism of CXCR3 on 66.1 tumor cells inhibited experimental lung metastasis, and this antimetastatic activity was compromised in mice depleted of natural killer cells. Systemic administration of AMG 487(5 mg/kg;s.c.;twice daily) also inhibited experimental lung metastasis[3]. In mice, injection of AMG-487 (i.c.v.)significantly attenuated the accumulation of c-fos in neurons induced by polyinosinic-polycytidylic acid (PIC)[5]. WT mice treated with AMG-487 (5 µg/g twice a day) showed a 45% reduction in bone loss and decreased osteoclasts after LPS injections[6]. Meanwhile, AMG 487 treatment significantly reduced bone loss in mice[7].

Cells treated or not with 1 µM AMG487 or dimethyl sulfoxide (DMSO) vehicle were placed in the upper well and various concentrations of human or mouse rCXCL9, rCXCL10 and rCXCL11 were added to the lower wells. After incubation of the plates for 18 h (C26 cells) or for 40 h (HT29 cells) at 37 C in 5% CO2 atmosphere, non-migrated cells were removed from the upper well and the migrated cells collected on the lower side of the insert were stained using crystal violet dye and enumerated. |

Preparation Method |
For the induction of pulmonary metastases, HT29 cells or C26 cells were delivered by intravenous tail injection into SCID or Balb/c mice, respectively. For the polymetastatic liver model, HT29 cells or C26 cells were injected intravenously into the portal vein of Nude or Balb/c mice, respectively. The curative treatment of the mice-bearing metastases was achieved by treating the animals twice daily on days +5 to +12 (syngeneic C26 model) or on days +5 to +23 (immunodeficient HT29 model) with subcutaneous injections of 5 mg/kg of AMG 487 or vehicle. The preventive treatment to antagonise CXCR3 was performed by incubating the colon cancer cells with 1 µM of AMG 487 or vehicle for 18 h in vitro before their injection into mice and by treating concomitantly the animals twice daily on days 1 and 0 with subcutaneous injections of 5 mg/kg of AMG487 or vehicle. |
