identified as a new structural motif for obtaining potent inhibitors of human mast cell chymase. For example, 1-naphthyl derivative 5f had an IC50 value of 29 nM and (E)-styryl derivative 6g had an IC50 value of 3.5 nM. An X-ray structure for 5f.chymase revealed key interactions within the enzyme active site. Compound 5f was selective for inhibiting chymase versus eight serine proteases. Compound 6h
一系列的β-羧酰胺基膦酸(in)酸(2)被确定为获得有效的人肥大细胞糜酶抑制剂的新结构基序。例如,1-萘基衍生物5f的IC 50值为29nM,(E)-苯乙烯基衍生物6g的IC 50值为3.5nM。5f.chymase的X射线结构揭示了酶活性位点内的关键相互作用。与8种丝氨酸蛋白酶相比,化合物5f对抑制糜蛋白酶具有选择性。化合物6h在大鼠中可口服生物利用(F = 39%),并且在仓鼠炎症模型中口服有效。
