ATI-2341, pepducin targeting the C-X-C chemokine receptor type 4 (CXCR4), is an allosteric agonist activating the inhibitory heterotrimeric G protein (Gi) to promote inhibition of cAMP production and induce calcium mobilization.

CXCR4:194 nM(EC50)

Receptors(CXCR4-eGFP) are transiently transfected into HEK-293 cells and are plated 24 h after transfection on glass coverslips coated with poly-D-lysine. The next day, cells are treated with either vehicle alone or with varying concentrations of ATI-2341 for 30 min at 37 °C followed by fixation with methanol for 5 min at −20 °C. GFP fluorescence is visualized directly using a Zeiss Axiovert inverted microscope. Images are processed using Adobe Photoshop and Adobe Illustrator. (Only for Reference)
