Acid Ceramidase Inhibitor IV, BOC-Calbiochem

产品说明

一般描述

A cell-permeable, chemically and metabolically stable (t_1/2 >5 h in aqueous buffers at pH 4.5 and 7.4; t_1/2 >2 h in murine plasma at 37 °C) benzoxazolone carboxamide (BOC) compound that inhibits acid ceramidase (AC) activity in a potent (IC₅₀ = 79 nM against HEK293 lysosomal lysate AC activity) and selective manner via covalent modification of the active site Cys143, exhibiting little or no potency toward a panel of 15 enzymes, including proteases, lipoxygenases, cyclooxygenases, sPLA₂, and monoacylglycerol lipase (67% inhibition of cathepsin D and ≤17.1% inhibition of the rest at 10 µM). Culture treatment results in long-lasting (>6 h) suppression of cellular AC activity in murine macrophage-like Raw 264.7 and human colon adenocarcinoma SW403 cells (IC₅₀ with 3 h treatment = 400 and 825 nM, respectively), as well as built-ups of cellular AC substrates Cer(d18:0/16:0) & Cer(d18:1/16:0) in a dose-dependent manner. Intraperitoneal injection (10 mg/kg) effectively inhibits tissue AC activity in multiple organs, including lung, heart, kidney, brain hippocampus, and liver (by 70%, 60%, 44%, 40%, 35%, respectively), with good pharmacokinetic properties (T_max = 30 min, C_max = 1.768 µg/mL, t_1/2 = 458 min, AUC_{0-8 h} = 0.31 mg·min/mL; 10 mg/kg i.p.).
