The present invention is directed to compounds which suppress immune responses and/or selectively inhibit complement. These compounds contain an aromatic ring and are substituted dihydrobenzofurans, spirobenzofuran-2(3H)-cycloalkanes, and their open chain intermediates. The compounds of the present invention, and the phamaceutically acceptable salts thereof, interrupt the proteolytic processing of C5 to bioactive components, exhibit immunosuppressive activites, and have therapeutic utility in the amelioration of disease and disorders mediated by complement and/or immune activity.
本发明涉及抑制免疫反应和/或选择性抑制补体的化合物。这些化合物含有芳香环,并且是取代二氢苯并呋喃、螺苯并呋喃-2(3H)-环戊烷及其开链中间体。本发明的化合物及其药学上可接受的盐中断C5的蛋白酶加工为生物活性成分,表现出免疫抑制活性,并在改善由补体和/或免疫活性介导的疾病和紊乱方面具有治疗效用。
