rwj-58643 hydrochloride

RWJ 58643 is a reversible beta-tryptase and trypsin inhibitor. Low-dose RWJ-58643 (100 microg) and budesonide (200 microg) significantly reduced symptoms, eosinophils and levels of IL-5 following NAC. However, higher doses of RWJ-58643 (300 and 600 microg) caused a late eosinophilia and preceding increases in IL-5 compared with placebo.

RWJ-58643是一种用于研究抑制过敏性炎症状况的β-胰蛋白酶和胰蛋白酶抑制剂。该化合物在较低剂量(100mg)可有效减轻鼻部过敏症状、嗜酸性粒细胞浸润以及白细胞介素-5(IL-5)的水平。但在较高剂量(300mg和600mg)时，观察到嗜酸性粒细胞的增多和IL-5水平的升高，显示出明显的剂量依赖性反应。
