title: Molecular structures of three hydroxyl derivatives of the hepatic carcinogen acetylaminofluorene. Evidence for preferred orientation of the acetylamino side-chain.
abstract: The molecular and crystal structures of three hydroxyl derivatives of 2-acetylaminofluorene (AAF), have been determined by X-ray crystallographic analysis. The structures of l-hydroxyl-AAF, N-hydroxyl-AAF and 3-hydroxyl-AAF have shown that in general their geometries are similar, both in respect bond distances and angles, and in respect of side-chain disposition. Possible reasons for the differences in biological activity between the three derivatives are discussed.
