生物活性

Description

AMG 487 is an antagonist of the chemokine receptorCXCR3, which inhibits binding of125I-IP-10 and125I-ITAC to CXCR3 withIC50values of 8.0 and 8.2 nM, respectively.

IC50& Target

IC50: 8.0 nM (125I-IP-10 binding to CXCR3), 8.2 nM (125I-ITAC binding to CXCR3)

In Vitro

AMG 487 inhibits CXCR3-mediated cell migration by the three CXCR3 chemokines (IP-10 IC50=8 nM, ITAC IC50=15 nM, and MIG IC50=36 nM). Furthermore, AMG 487 inhibits calcium mobilization in response to ITAC (IC50=5 nM)[1]. AMG487 (1 μM) develops into fewer lung metastases, and the lungs are significantly smaller than vehicle-treated lungs[2]. AMG487 abrogates proliferation/survival of C26 tumour cells[3].

In Vivo

AMG 487 (0.03-10 mg/kg, s.c.) exhibits significant reduction in cellular infiltration into the lungs in a dose dependent manner[1]. AMG487 (5 mg/kg, s.c., twice daily) develops fewer metastases than that in vehicle-treated mice[2]. AMG487 (5?mg/kg, s.c.)-treated mice exhibits fewer pulmonary nodules than the control mice in both the models. AMG487 reduces the tumour volume[3].
