Valategrast is a potent and orally active dual antagonist of integrin α4β1 (VLA-4) and α4β7, with the potential for Chronic obstructive pulmonary disease (COPD) and asthma treatment.
Zaurategrast ethyl ester is the ethyl ester prodrug of CT7758 and is an α4β1 α4β7 integrin antagonist. It is used for the treatment of inflammatory and autoimmune disorders.
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].

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].
