Hazard Information

Uses

Vercirnon (GSK1605786A) sodium is an orally bioavailable, selective, and potent antagonist of CCR9. Vercirnon sodium inhibits CCR9-mediated Ca2+ mobilization and chemotaxis on Molt-4 cells with IC50 values of 5.4 and 3.4 nM, respectively. Vercirnon sodium is selective for CCR9 over CCR1-12 and CX3CR1-7 (IC50s>10 μM for all). Vercirnon sodium 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[1].

in vivo

Vercirnon (GSK1605786A) sodium (10, 50 mg/kg; s.c.; twice per day; starting at 2 weeks of age until 12 weeks of age) ameliorates the severity of intestinal inflammation in the TNFΔARE mouse model^[1].

Animal Model:	C57BL/6 mice (TNFΔARE Mouse Model of Terminal Ileitis)^[1]
Dosage:	10, 50 mg/kg
Administration:	Subcutaneous; twice per day; starting at 2 weeks of age until 12 weeks of age
Result:	Resulted in complete protection from the severe inflammation associated with TNF- overexpression at 50 mg/kg. A similar protective effect was also noted with a lower dose.

IC 50

CCR9: 10 nM (IC₅₀)
