Synthesis of novel estrogen receptor antagonists using metal-catalyzed coupling reactions and characterization of their biological activity.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Estrogen receptor (ER) antagonists are valuable in the treatment of ER-positive human breast cancer. In this study, we designed and synthesized nine new derivatives of 17β-estradiol (E2) with a bulky side chain attached to its C-7α position, and determined their ER antagonistic activity using in vitro bioassays. Four of the derivatives showed a strong inhibition of ERα transactivation activity in a luciferase reporter assay and blocked ERα interactions with coactivators. Similarly, these derivatives also strongly inhibited the growth of the ERα-positive human breast cancer cells. Computational docking analysis was conducted to model the interaction of these antagonists with the human ERα and showed that they could tightly bind to the ERα in a manner similar to that of ICI-182,780, a pure ER antagonist. These results provide an example that attachment of a bulky side chain to the C-7α position of E2 can produce ER antagonists with ER affinity comparable to that of ICI-182,780.
