Carcinogenic nitrogen compounds. Part LXXVI. Penta- and hexacyclic indenoindoles
Abstract
A number of new indenoindoles containing five or six rings have been prepared from acenaphthenone, angular naphthindanones, s-hydrindacen-1-one, and 2,3,4,6,7,8-hexahydro-1H-benz[f]inden-1-one, as potential carcinogens and enzyme inducers. Several of these compounds are highly potent inducers of zoxazolamine hydroxylase.
