製品説明 A-205804 is a potent and selective inhibitor of E-selectin and ICAM-1 expression with IC50 of 20 nM and 25 nM respectively.
ターゲット E-selectin ICAM-1
IC50 20 nM 25 nM [1]
In vitro試験 A-205804 selectively inhibits the surface expression of the cell adhesion molecules ICAM-1 and E-selectin in human endothelial cells. A-205804 inhibites the IL-1β-induced expression of E-selectin (IC50 = 20 nM) and ICAM-1 (IC50 = 10 nM) with essentially the same level of potency as that for TNFα-induced expression. For reasons which are unclear, the ability of A-205804 to inhibit PMA-induced E-selectin expression is significantly reduced (IC50 > 1000 nM), but A-205804 is a potent inhibitor of ICAM-1 expression (IC50 = 40 nM) using this protein-kinase C-activating agent.

キナーゼアッセイ: [1]

Cell ELISA Assay Primary HUVECs are plated in 96-well plates at 5 × 104 cells/mL in EBM/2% FBS/human epidermal growth factor/bovine brain extract/gentamicin. The following day test compounds are added and the plates incubats for 24 h at 37 °C. TNFα then is added to a final concentration of 5 ng/mL, and the plates are incubated for an additional 6 h at 37 °C. The plates are washed once with D-PBS, and primary antibody is added in D-PBS/2% BSA /0.01% NaN3. The antibodies used are mouse monoclonal anti-ELAM-1, anti-ICAM-1, and anti-VCAM-1. The plates are stored overnight at 4 °C and then washes three times with D-PBS. Secondary antibody, HRP-conjugated donkey anti-mouse IgG in D-PBS/2%BSA, is added, and the plates are incubated for 1−2 h at room temperature and then washes three times with D-PBS. OPD solution is added to the wells, the plates are developed for 15−20 min and neutralizes with 1 N sulfuric acid, and the absorbance is read at 490 nm.

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.

Rat dose (mg/kg) = mouse dose (22.4 mg/kg) ×  mouse Km(3)  = 11.2 mg/kg
