In Vitro Use Guide
It was investigated the possibility of oxyphenbutazone (OPh) inhibited the complement system and thus ameliorated the acute pathological changes induced by immune complexes. Treatment of fresh human serum with OPh inhibited both the classical and alternative complement (C) pathway activities in a dose-dependent fashion with a 50% inhibition dose 1.3 mg/ml. OPh was shown to form complexes with C5, thereby inhibiting the interaction between C3b and C5 and the cleavage of the latter into phlogistic fragments.
