生物活性

ZD8321 is a potent inhibitor of human Neutrophil elastase (NE) with a K_i of 13±1.7 nM.

IC₅₀ & Target

Ki: 13±1.7 nM (Neutrophil elastase)^[1]

体外研究
(In Vitro)

TNFα-activated HUVEC is dose dependently inhibited by ZD8321.The adhesion between cancer cells with high elastase activity and TNFα-activated HUVEC is also inhibited by ZD8321. Expression of cell surface E-selectin by NE stimulation is suppressed in the presence of ZD8321. The concentration of soluble E-selectin in the medium increases after adhesive reaction between neutrophils and HUVEC. This increase is also dose dependently inhibited by ZD8321^[2].

Cell Assay ^[2]	HUVECs are cultured in RPMI 1640 containing 5% FBS for 6 h in collagen-coated, 24-well plates before the experiment. Some of the confluent HUVECs are further incubated with TNFα (1 ng/mL) and ZD8321 (0-50 mM), or with human NE (0-100ng/mL) for 4 h at 37°C. For adhesion assays, cancer cells resuspended in RPMI 1640 containing 5% FBS are added to each HUVEC-layered well. The plates are shaken at 700 rpm for 10 min at room temperature, washed twice with PBS, and examined by phase-contrast microscopy to determine the number of cells bound onto the HUVEC monolayer. The adhesive reactions of neutrophils to HUVEC are also analyzed in this manner^[2]. Shanghai Jinpan Biotech Co Ltd has not independently confirmed the accuracy of these methods.
