Introduction of 402567-16-2 :

Firategrast (SB 683699) is an orally active and specific α4β1/α4β7 integrin antagonist. Firategrast reduces trafficking of lymphocytes into the central nervous system (CNS) and decreases multiple sclerosis (MS) activity[1][2][3]. IC50 & Target: α4β1/α4β7[1] In Vitro: Firategrast (0.1-10 µM; 1 hour) significantly reduces chronic lymphocytic leukemia (CLL) cells adhesion[2].
Firategrast is a potent Integrin α4β1 (VLA-4) antagonist (IC50=198 nM) at inhibiting the binding of soluble VCAM/Fc chimeric protein (sVCAM-1) to G2 acute lymphoblastic leukemia (ALL) cells. VLA-4 is composed of CD49d (α4) and CD29 (β1)[1][4].
In Vivo: Firategrast (30 mg/kg/day in drinking water; starting 2 or 7 days post transplantation to 21 days) shows an overall reduction of leukemic cells in the spleen[3].
