產(chǎn)品介紹

Pranlukast hemihydrate is a highly potent, selective and competitive antagonist of peptide?leukotrienes. Pranlukast inhibits [3H]LTE4, [3H]LTD4, and [3H]LTC4?bindings to lung membranes with?Kis of 0.63±0.11, 0.99±0.19, and 5640±680 nM, respectively.

產(chǎn)品描述: Pranlukast hemihydrate is a highly potent, selective and competitive antagonist of peptide?leukotrienes. Pranlukast inhibits [3H]LTE4, [3H]LTD4, and [3H]LTC4?bindings to lung membranes with?Kis of 0.63±0.11, 0.99±0.19, and 5640±680 nM, respectively.
靶點(diǎn): LTE4:0.63 nM (Ki);LTD4;0.99 nM (Ki);LTC4:5640 nM (Ki)
體內(nèi)研究: Carrageenan (CAR, 5 mg per mouse) is injected i.p. 24 h before LPS (50 p,g per mouse) is injected i.v. Various doses of Pranlukast (ONO-1078; 40, 20, and 10 mmol/kg), AA-861 (20, 10, and 5 mmol/kg), Indomethacin (40 mmollkg), and the controls are injected s.c. into mice 30 min before they are challenged with 50 p,g of LPS. The maximum soluble doses are 0.6 mmol/mL in 10% DMSO for AA-861 and 1.2 mmol/mL in 10% ethanol for Pranlukast. These solutions are used as the maximum doses for the treatments. The mortality of mice is significantly decreased in AA-861- Pranlukast-treated mice relative to that in the control mice. Pretreatment with CAR (5 mg i.p.) renders the mice more sensitive to the effect of LPS. Although the survival rate of mice treated with each solvent is 20% at 72 h after LPS (50 p,g per mouse) administration, s.c. treatment with AA-861 (20 mmol/kg) or Pranlukast (40 mmol/kg) significantly increases the survival rate after the LPS administration (AA-861, P<0.001; Pranlukast, P<0.01)
