Zusammenfassung

Die Hemmung von Trypsin und Chymotrypsin des Menschen durch verschiedene Proteinaseninhibitoren pflanzlicher Herkunft wurde unter Verwendung von Dünndarmsaft ohne Trennung der beiden Enzyme mit synthetischen Amidsubstraten (BAPA, GLUPHEPA) untersucht and mit der Hemmung der entsprechenden Rinderenzyme verglichen. Als Inhibitoren dienten Extrakte und Inhibitorpräpa-rate aus Leguminosensamen (13Papilionoideae, 2 Caesalpinioideae, 3Mimosoideae), Kartoffeln and Weizenkleie. Die Samenextrakte von 9 der untersuchten Leguminosenarten hemmen menschliches Chymotrypsin mehr und menschliches Trypsin weniger als die Rinderenzyme, 5 Samenextrakte hemmen beide Humanenzyme mehr als die Rinderenzyme, während nur ein Extrakt beide Humanenzyme weniger als die Rinderenzyme und ein weiterer Humantrypsin mehr and Humanchymotrypsin weniger hemmt. Humanchymotrypsin wird durch ungefähr zwei Drittel der untersuchten Arten zwischen zwei- bis zwölfmal so stark gehemmt wie das Rinderenzym. Die Hemmung von Chymotrypsin erreicht Werte, wie sie sonst nur für Trypsin bekannt sind. Inhibitorpräparate aus den untersuchten Leguminosen und aus zwei anderen pflanzlichen Lebensmitteln zeigen ähnliche Ergebnisse.

Summary

Inhibition of human trypsin and chymotrypsin by proteinase inhibitors of plant origin was studied using the juice from the small intestine, without separation of the two enzymes, and synthetic amide substrates (BAPA, GLUPHEPA). The results were compared with the inhibition of the corresponding bovine enzymes. Extracts and preparations from legumeseeds (13Papilionoideae, 2 Caesalpinioideae, 3Mimosoideae), potato tubers and bran were used as inhibitors; 9 of the seed extracts studied inhibited human chymotrypsin more and human trypsin less than the bovine enzymes. In similar tests 5 seed extracts inhibited the two human enzymes more than the bovine enzymes, whilst only one extract inhibited the two human enzymes less than the two bovine enzymes, and another inhibited human trypsin more and human chymotrypsin less than the bovine enzymes. In particular, human chymotrypsin was between two and twelve times as strongly inhibited as the bovine enzyme by some two thirds of the species studied, sometimes exhibiting chymotrypsin-inhibitory activities usually observed only with trypsin. Inhibitor preparations from the above legumes and two non-leguminous plant foods exhibited similar results.
