BT2 is a thermostable small-molecule inhibitor of vascular permeability and angiogenesis, interacts with MEK1 and inhibits ERK phosphorylation, FosB/ΔFosB, and VCAM-1 expression.BT2 blocks endothelial FosB/ΔFosB expression, proliferation, migration and wound repair after in vitro injury and network formation.BT2 also inhibited a range of other regulatory genes involved in cell proliferation, migration, angiogenesis, and inflammation including intercellular adhesion molecule-1 (ICAM-1), CXCL2, KLF5, Egr-1, and Fos.BT2 reduced retinal leakage in rats at least as effectively as aflibercept, a first-line therapy for nAMD/DR.
