Integrinmodulator 1 is a potent and selective α4β1 integrin agonist, with an IC50 of 9.8 nM for RGD-binding α4β1. Integrinmodulator 1 increases cell adhesion mediated by α4β1 integrin, with an EC50 of 12.9 nM[1]. Integrinmodulator 1 (2-10 μg mL; 30 min) significantly increases Jurkat E6.1 cell adhesion[1].Integrinmodulator 1 (1-100 nM; 1 h) strongly and significantly increases ERK1 2 phosphorylation in Jurkat E6.1 cells[1].Integrinmodulator 1 (1 nM-10 μM; 30 min) significantly increases the binding of HUTS-21 antibody to Jurkat E6.1 cells in a concentration-dependent manner[1].
