✦ Synopsis


Cytochemical methods were used to demonstrate the inhibitory effect of salicylazosulfapyridine (SASP) on the activity of neutral proteases produced by neutrophilic granulocytes (PMN proteases). The SASP metabolites (5-aminosalicylic acid and sulfapyridine), produced by splitting of SASP by bacteria in the colon, did not inhibit the activity of PMN proteases. Paradoxically, sulfapyridine intensified PMN protease activity. A similar effect however could not be demonstrated for 5-aminosalicylic acid.
