一般描述
A cell-permeable, chemically and metabolically stable (t1/2>5 h in aqueous buffers at pH 4.5 and 7.4;t1/2>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 ?M). 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 (IC50with 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 (Tmax= 30 min,Cmax= 1.768 ?g/mL,t1/2= 458 min, AUC0-8 h= 0.31 mg·min/mL; 10 mg/kg i.p.).

Please note that the molecular weight for this compound is batch-specific due to variable water content. Please refer to the vial label or the certificate of analysis for the batch-specific molecular weight. The molecular weight provided represents the baseline molecular weight without water.
