Cat.No. 4528 - (±)-NBI 74330 | C32H27F4N5O3 | CAS No. 473722-68-8
Description: Potent and selective CXCR3 antagonist
Chemical Name: N-1-[(3-4(-Ethoxyphenyl)-3,4-dihydro-4-oxopyrido[2,3-d]pyrimidin-2-yl]ethyl]-4-fluoro-N-(3-pyridinylmethyl)-3-(trifluoromethyl)benzeneacetamide
Purity: ≥98% (HPLC)

Biological Activity

Potent and selective CXCR3 antagonist; potently inhibits 125I-CXCL10 binding to CXCR3 (pKi = 8.13). Inhibits calcium mobilization in response to CXCL11 and CXCL10 in RBL cells. Exhibits no significant effect on chemotaxis induced by CXCR4 or CCR7. Displays a five-fold greater affinity for CXCR3 than (±)-AMG 487.

This product is racemic.
