FX-06

FX-06 (Fibrin-derived peptide Bβ15-42) is a fibrin Bbeta chain-derived peptide. FX-06 binds to VE-cadherin and inhibits leukocyte transmigration and initiates VE-cadherin-mediated signaling. FX-06 can be used in the research of ischemia/reperfusion injury, Dengue shock syndrome (DSS)[1][2][4].

FX-06 (50 μM, 3 days) inhibits the production of D2HG in HEK-293T cells transfected with IDH1 R132H[2].

FX06 (2.4 mg/kg, i.v. bolus) shows significantly improved pulmonary and circulatory function in a pig model of hemorrhagic shock and reperfusion[3]. FX06 (2.4 mg/kg, i.p., twice daily) improves survival and reduces capillary leak in mice with Dengue-induced shock[4]. FX06 (3.6 mg/kg, i.v.) protects mice from Ischemia/reperfusion (I/R)-induced kidney injury by aiding in epithelial cell proliferation and tissue repair[5]. Animal Model: Pig model of hemorrhagic shock and reperfusion [3] Dosage: 2.4 mg/kg Administration: Intravenous injection (i.v.) bolus Result: Reduced raccumulation of myeloperoxidase-pos. cells (mainly neutrophils) in myocardium, liver, and small intestine, and reduced interleukin-6 plasma levels. Animal Model: Mice with Dengue-induced shock[4] Dosage: 2.4 mg/kg Administration: Intraperitoneal injection (i.p.) Result: Significantly improved survival rates, reduced capillary leak within lungs and the intestine, and reduced hemoconcentration and fibrinogen consumption.
