Lifitegrast (SAR 1118) sodium is a potent integrin antagonist. Lifitegrast sodium blocks the binding of intercellular adhesion molecule 1 (ICAM-1) to lymphocyte function-associated antigen 1 (LFA-1), interrupting the T cell-mediated inflammatory cycle. Lifitegrast sodium inhibits Jurkat T cell attachment to ICAM-1 with an IC 50 of 2.98 nM. Lifitegrast sodium can be used for researching dry eye disease In Vitro Lifitegrast (SAR 1118) inhibits T cell-mediated inflammation by blocking the binding of two important cell surface proteins (lymphocyte function-associated antigen 1 and intercellular adhesion molecule 1), thus lessening overall inflammatory responses. Lifitegrast strongly inhibits Jurkat T cell attachment to ICAM-1 with an IC 50 of 2.98 nM. MCE has not independently confirmed the accuracy of these methods. They are for reference only. In Vivo Lifitegrast has potent anti-inflammatory activity on corneal inflammation induced by antibiotic-killed P. aeruginosa and S. aureus in the presence of a silicone hydrogel lens with the optimal application being a 1% solution applied either 2 or 3 times prior. MCE has not independently confirmed the accuracy of these methods. They are for reference only. Form:Solid IC50& Target:αLβ2
