Biological Activity
hLF1-11 (1, 10, and 100 μg/mL) directs differentiation of monocytes toward a macrophage subset during granulocyte-macrophage colony-stimulating factor (GM-CSF)-driven monocytes differentiation[2].
hLF1-11 (0.5-250 μg/mL) inhibits human MPO activity[3].
hLF1-11 (100 μg/mL, 90 min) inhibits ROS induction induced by LPS in monocytes[3].
hLF1-11 (8-34 μΜ, 2 h) is active against fluconazole-resistant C. albicans[5].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
hLF1-11 (40 μg/kg, i.v.) is active against C. albicans-infected mice[6].
