  • Title: Inhibition of the induction of collagenase by interleukin-1 beta in cultured rabbit synovial fibroblasts after treatment with the poly(ADP-ribose)-polymerase inhibitor 3-aminobenzamide.
    Author: Ehrlich W, Huser H, Kröger H.
    Journal: Rheumatol Int; 1995; 15(4):171-2. PubMed ID: 8835300.
    Abstract:
    3-Aminobenzamide is an inhibitor of poly-(ADP-ribosyl)ation. In concentrations from 3 to 10 mM it reduced the collagenase activity in culture supernatants of interleukin-1 beta-stimulated rabbit synovial fibroblasts. 3-Aminobenzoate, not an inhibiter of poly(ADP-ribosyl)ation, had no effect on collagenase activity at a concentration of 10 mM. We concluded that poly(ADP-ribosyl)ation plays a role in the induction of the expression of collagenase and that 3-aminobenzamide can inhibit this process.
