Vercirnon (GSK1605786A, CCX282-B) is a potent, selective, orally bioavailable antagonist of CCR9, inhibits CCR9-mediated Ca2+ mobilization and chemotaxis on Molt-4 cells with IC50 of 5.4 and 3.4 nM, respectively.Vercirnon (GSK1605786A, CCX282-B) displays high selectivity for CCR9 over CCR1-12 and CX3CR1-7 (IC50>10 uM).Vercirnon (GSK1605786A, CCX282-B) is an equipotent inhibitor of CCL25-directed chemotaxis of both splice forms of CCR9 (CCR9A and CCR9B) with IC50 values of 2.8 and 2.6 nM, respectively.CCX282-B also inhibited mouse and rat CCR9-mediated chemotaxis.Inhibition of CCR9 with CCX282-B results in normalization of Crohn's disease such as histopathology associated with the TNF(ΔARE) mice.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
