Suppression of streptococcal cell wall-induced arthritis by a potent protease inhibitor, bis(5-amidino-2-benzimidazolyl)methane.

Abstract

Bis(5-amidino-2-benzimidazolyl)methane, a powerful synthetic trypsin inhibitor, proved to be highly effective in suppressing the arthritis induced by streptococcal cell wall fragments in Lewis rats. It reduced not only the degree of synovitis, osteitis, and hematopoietic hyperplasia in the distal extremities, but also the degree of associated granulomatous inflammation in the liver. The results suggest that trypsin-like proteases play an important role in this arthritis model and that inhibitors may be useful in the treatment of similar arthritic conditions in humans.
