lifitegrast is an approved drug (FDA (2016))
Compound class:
Synthetic organic
Comment: It is postulated that lifitegrast (SAR 1118) interacts with the lymphocyte function-associated antigen-1 (LFA-1) to inhbit the LFA-1/ICAM-1 adhesion interaction and was approved for the treatment of Dry Ey in 2016 [7,9]. LFA-1 is a heterodimeric member of the β2 integrin family which is essential for adhesion, migration, and proliferation of T cells at sites of inflammation, and is involved in T cell specific immune responses through the formation of adhesive interactions and immunological synapses. Intercellular adhesion molecule‑1 (ICAM‑1) is the cognate ligand of LFA-1.The compound formulation is claimed in patent WO2014100135 [7].

Bioactivity Comments |
No specific binding data are provided in [9] to substantiate the lifitegrast/LFA-1 interaction. Target engagement is inferred from biological assays showing inhibition of T cell adhesion and inhibition of inflammatory mediator secretion. In in vitro assays, lifitegrast inhibits Jurkat T cell and HuT 78 T cell adhesion to immobilised ICAM-Ig with IC50s of 2.98nM and 9nM respectively [9]. Lifitegrast was designed to have minimal systemic exposure, to limit action at sites other than at the site of administration [7]. |
