L-asarinin 降低外周血 IL-12 浓度并抑制 CXCR3 和 TLR4 的表达,这意味着 Asarinin 可能在 TLR4 通路中发挥作用,并延长同种异体心脏的存活时间。
产品描述
Asarinin reduces peripheral blood concentration of IL-12 and inhibits the expression of CXCR3 and TLR4, which means Asarinin may have a role on the TLR4 pathway and produce prolongation of allograft heart survival.
激酶实验
Samples containing either URB602 (300 μM), MGL (1.4 pM), or both URB602 and MGL are incubated at 37°C for 30 min in assay buffer. At various time points, the reaction is stopped with an equal volume of ice-cold methanol and directly analyzed in positive ionization mode by LC/MS. A SB-CN column (150×2.1 mm i.d., 5 μm) eluted is used with a linear gradient of methanol in water containing 0.25% acetic acid and 5 mM ammonium acetate (from 60% to 100% of methanol in 8 min) at a flow rate of 0.5 mL/min with column temperature at 50°C. Capillary voltage is set at 4 kV and fragmentor voltage is 100V. Nebulizer pressure is set at 60 psi. N2 is used as drying gas at a flow rate of 13 liters/min and a temperature of 350°C. ESI is in the positive mode and a full scan spectrum is acquired from m/z 100 to 600. Extracted ion chromatograms are used to quantify URB602 ([M+H]+, m/z 296)[2].
