An analysis has been made of the C-H...O interactions in cyclopenta[a]phenanthrenes, for which structural data on fifteen 15,16-dihydrocyclopenta[a]-phenanthren-17-ones are available. These compounds mostly contain only one O atom, a carbonyl group a

A strongly electronegative, bay-region analogue of the potent carcinogen 15,16-dihydro-11-methylcyclopenta[a]phenanthren-17-one, namely 15,16-dihydro-11-trifluoromethylcyclopenta[a]phenanthren-17-one, is mutagenic to Salmonella typhimurium TA100. Als

Direct comparison of skin-tumour induction by 15,16-dihydro-11-methylcyclopenta[a]phenanthren-17-one (I) and by benzo[a]pyrene on mouse skin, both by repeated application or by initiation with a single dose followed by promotion with croton oil, demo

A new method of synthesis of the lead phthalocyanin and the chemical properties of its diazotate are described. The use of this reagent for high resolution studies of the localization of intra- and extralysosomal acid phosphatases and esterases in pl

The proposal that an unobstructed bay region is a prerequisite for tumorigenic activity in cyclopenta[a]phenanthrene-17-ones is not supported by the observation of the tumorigenicity of 15,16-dihydro-1,11-methanocyclopenta[a]phenanthrene-17-one towar
