Biochem/physiol Actions

BIO 1211 is a selective, tight-binding α4β1 (VLA-4, very late antigen-4; koff = 1.4 x 10-4/s, KD = 70 pM) integrin antagonist (VCAM-Ig Jurkat surface binding IC50 = 1 nM; integrin-mediated cell adhesion IC50 = 4 nM/α4β1, 2 μM/α4β7, >100 μM/α1β1, α5β1, α6β1, αLβ2, αIIBβ3) based on the Leu-Asp-Val (LDV) sequence from the alternatively spliced connecting segment-1 (CS-1) of fibronectin (aa 1980-1983). In addition to probing α4β1-mediated cellular responses, BIO 1211 is also widely used in animal disease models in vivo, including MS (5-10 mg/kg; murine EAE) and asthma (1-10 mg/kg via intranasal or nebulizer to mice, rats, sheep; 3 mg/sheep iv.).

BIO1211 is a small peptidyl potent antagonist of the activated form of alpha4beta1 integrin. The effect of enalapril on the in vitro and in vivo cleavage of BIO1211 was investigated. In heparinized blood, plasma and rat liver, lung and intestinal

Lymphangiogenesis plays a pivotal role in diverse pathological conditions. Here, we demonstrate that a carbohydrate-binding protein, galectin-8, promotes pathological lymphangiogenesis. Galectin-8 is markedly upregulated in inflamed human and mouse corneas, and galectin-8 inhibitors reduce inflammatory lymphangiogenesis. In the mouse model
