Integrin modulator 1 is a potent and selective α4β1 integrin agonist, with an IC50 of 9.8 nM for RGD-binding α4β1. Integrin modulator 1 increases cell adhesion mediated by α4β1 integrin, with an EC50 of 12.9 nM[1]. Integrin modulator 1 (2-10 μg mL; 30 min) significantly increases Jurkat E6.1 cell adhesion[1].Integrin modulator 1 (1-100 nM; 1 h) strongly and significantly increases ERK1 2 phosphorylation in Jurkat E6.1 cells[1].Integrin modulator 1 (1 nM-10 μM; 30 min) significantly increases the binding of HUTS-21 antibody to Jurkat E6.1 cells in a concentration-dependent manner[1].

Echistatin TFA, the smallest active RGD protein belonging to the family of disintegrins that are derived from snake venoms, is a potent inhibitor of platelet aggregation. Echistatin is a potent inhibitor of bone resorption in culture. Echistatin is a potent antagonist of αIIbβ3, αvβ3 and α5β1[1][2][3][4]. [1]. J Musial, et al.

BIO5192 hydrate is a selective and potent integrin α4β1 (VLA-4) inhibitor (Kd<10 pM). BIO5192 hydrate selectively binds to α4β1 (IC50=1.8 nM) over a range of other integrins. BIO5192 hydrate results in a 30-fold increase in mobilization of murine hematopoietic stem and progenitors (HSPCs) over basal levels[1][2]. The combination of BIO5192 hydrate (1 mg kg; i.v.) and Plerixafor (5 mg kg; s.c.) exert an additive effect on progenitor mobilization[1].BIO5192 hydrate (30 mg kg; s.c; bid; during days 5 through 14) delays paralysis associated with EAE (experimental autoimmune encephalomyelitis)[2].BIO5192 hydrate (1 mg kg, i.v.) shows the terminal half-life is 1.1 hours. BIO5192 hydrate (3, 10, and 30 mg kg; s.c.) shows half-lives of 1.7, 2.7, and 4.7 hours, respectively. The blood plasma curves show that the AUC for the s.c. route of administration increased about 2.5-fold from 5,460 h*ng ml for the 3 mg kg dose to 14,175 h*ng ml for the 30 mg kg[1].

Bexotegrast, also known as PLN-74809, is a small-molecule, dual selective inhibitor of αVβ1 αVβ6 for idiopathic pulmonary fibrosis (IPF) and primary sclerosing cholangitis (PSC). These integrins cause upstream activation of TGF-β1 in actively fibrotic tissue. Inhibition of these integrins will block TGF-β1 activation, thereby preventing the growth of fibrotic tissue within the lung and bile ducts.
Cilengitide hydrochloride sis the salt form of Cilengitide, a cyclic Arg-Gly-Asp peptide with potential antineoplastic activity. Cilengitide binds to and inhibits the activities of the alpha(v)beta(3) and alpha(v)beta(5) integrins, thereby inhibiting endothelial cell-cell interactions, endothelial cell-matrix interactions, and angiogenesis.
