  Structure-activity relationship of antiestrogens. A study using triarylbutenone, benzofuran, and triarylfuran analogs as models for triarylethylenes and triarylpropenones

  摘要：

  In a study of the structure-activity relationship (SAR) of antiestrogens use has been made of certain 1,2,3-triarylbutenones, of 2-arylbenzofurans carrying aryl or aroyl substituents at C3, and of 2,3,4-triarylfurans as conformationally constrained models for triarylethylene (TAE) and triarylpropenone (TAP) prototypes. The position-specific contributions of substituents to receptor affinity and to agonist-antagonist profiles were used as aids in characterizing the relative binding orientation of the prototypes. Although most compounds were found to be weak receptor ligands and poorly active in vivo, the following conclusions could be drawn about their SAR: (i) (Z)-TAPs and TAEs interact with the receptor in an analogous manner using the trans-stilbene core, with their agonist-antagonist profiles depending on the nature of other substructures. (ii) Incorporation into the benzofuran framework introduces a stereoelectronic constraint that compromises the normal binding interactions of TAE, as well as TAP, prototypes, resulting in their poor affinities and weak biological activities. (iii) (E)-TAPs can interact with the receptor through their S-cis conformation, but such a binding mode is unlikely to account for their behavior as antagonists.
