| Abstract: | The influence of phenestrol and XTJI-51 (hexestrol alkylating derivatives) on uterine tissues and their ability to bind to estrogen receptors were studied. The both compounds studied exhibited estrogenic properties and imitated all effects of estradiol: they increased the uterine wet weight and the activity of thymidine kinase and glucose-6-phosphate dehydrogenase. Although their affinity for estrogen receptors was much weaker than the affinity of estradiol, their complexes with estrogen receptors were more stable than estrogen-receptor complexes. |
