== Function ==
[https://www.uniprot.org/uniprot/ITAL_HUMAN ITAL_HUMAN] Integrin alpha-L/beta-2 is a receptor for ICAM1, ICAM2, ICAM3 and ICAM4. It is involved in a variety of immune phenomena including leukocyte-endothelial cell interaction, cytotoxic T-cell mediated killing, and antibody dependent killing by granulocytes and monocytes.

== Publication Abstract from PubMed ==
LFA-1 (leukocyte function-associated antigen-1), is a member of the beta2-integrin family and is expressed on all leukocytes. This letter describes the discovery and preliminary SAR of spirocyclic hydantoin based LFA-1 antagonists that culminated in the identification of analog 8 as a clinical candidate. We also report the first example of the efficacy of a small molecule LFA-1 antagonist in combination with CTLA-4Ig in an animal model of transplant rejection.

Discovery and development of 5-[(5S,9R)-9-(4-cyanophenyl)-3-(3,5-dichlorophenyl)-1-methyl-2,4-dioxo-1,3 ,7-triazaspiro[4.4]non-7-yl-methyl]-3-thiophenecarboxylic acid (BMS-587101)--a small molecule antagonist of leukocyte function associated antigen-1.,Potin D, Launay M, Monatlik F, Malabre P, Fabreguettes M, Fouquet A, Maillet M, Nicolai E, Dorgeret L, Chevallier F, Besse D, Dufort M, Caussade F, Ahmad SZ, Stetsko DK, Skala S, Davis PM, Balimane P, Patel K, Yang Z, Marathe P, Postelneck J, Townsend RM, Goldfarb V, Sheriff S, Einspahr H, Kish K, Malley MF, DiMarco JD, Gougoutas JZ, Kadiyala P, Cheney DL, Tejwani RW, Murphy DK, Mcintyre KW, Yang X, Chao S, Leith L, Xiao Z, Mathur A, Chen BC, Wu DR, Traeger SC, McKinnon M, Barrish JC, Robl JA, Iwanowicz EJ, Suchard SJ, Dhar TG J Med Chem. 2006 Nov 30;49(24):6946-9.
