A concise route for highly substituted ring extended estrone analogues has been developed. The photophysical and biological study of these compounds revealed their efficacy as possible fluorescence probes in cancer chemotherapy.
after exploring a variety of C-19 substituents. 1,2-Dehydrogenation in combination with subsequent A-ring aromatization via retro-aldol reaction provided a flexible and efficient protocol for the synthesis of estrogens. To demonstrate the utility of the protocol, pharmaceutically attractive estrogens were synthesized from easily available 19-hydroxy-4-ene-3-keto steroids.
Novel 17α-bromoethynyl, 17α-chloroethynyl, 17-αiodoethynyl, 17-αtrifluoropropynyl, 17α-vinyl and 17α-triflourovinyl-17β-hydroxy (and/or 17β-alkoxy)-steroids have been prepared for biological examination.
Compounds and methods for modulating mesenchymal cell function, for instance smooth muscle and fibroblast proliferation or cytokine expression, and for treating conditions associated with mesenchymal cell function, for instance airway hyperresponsiveness associated with asthma. The compounds also suppress inflammation. The compounds are a class of estratriene derivates, and includes various derivatives of 2-methoxyestradiol comprising a group A, including a substituted aromatic substituent in the 2-, 6- or 17-position.
