The presence of a chymotrypsin-like enzyme in rat mast cells has been confirmed, and it has been shown that intact mast cells contain the fully activated enzyme without losing their histamine content. It has been shown by means of inhibitors that the chymotrypsin-like enzyme is distinct from the heat-labile SH enzyme required for the histamine releasing action of compound 48/80. The synthetic ester used as a substrate for chymotrypsin released histamine from rat mast cells probably by a non-enzymic reaction.
已证实大鼠肥大细胞中存在一种类胰凝乳蛋白酶,且已表明完整的肥大细胞含有完全活化的该酶,同时不会损失其组胺含量。通过抑制剂已表明,类胰凝乳蛋白酶不同于化合物48/80组胺释放作用所需的热不稳定巯基酶。用作胰凝乳蛋白酶底物的合成酯可能通过非酶促反应从大鼠肥大细胞中释放组胺。
