GLPG0187 is a broad-spectrum integrin receptor antagonist that exhibits selectivity for various integrin receptors, with the following IC50 values: αVβ1 at 1.3nM, αVβ3 at 3.7nM, αVβ5 at 2.0nM, αVβ6 at 1.4nM, αVβ8 at 1.2nM, and α5β1 at 7.7nM[1, 2]. GLPG0187 possesses anti-tumor activity, blocking the αvβ6 integrin receptor on cancer cells, locally preventing TGF-β activation, thereby reducing TGF-β signaling and immune evasion in cancer cells[3].
In vitro, GLPG0187 (20nM, 100nM, 200nM, 1µM) pretreatment of human small airway epithelial cells (HSAE) for 2h blocked SARS-CoV-2 delta and Omicron pseudovirus infection of airway epithelial cells in a dose-dependent manner[4]. Treatment of TALL-104 T lymphoblast cells with GLPG0187 (4µM) for 24h significantly enhanced the killing effect of TALL-104 T lymphoblast cells on HCT116 p53-null cells[5].
In vivo, GLPG0187 (100mg/kg) administered via intraperitoneal injection for 17 days in a mouse model of prostate cancer bone metastasis significantly reduced the number of tumor cells in the implanted metatarsal bones of the mice, significantly increased the number of osteoblasts, and significantly decreased microvessel density[6].
