Abstract
The 17beta-hydroxysteroid dehydrogenases (17beta-HSDs) play an important role in the regulation of steroid hormones, such as estrogens and androgens, by catalysing the reduction of 17-ketosteroids or the oxidation of 17beta-hydroxysteroids using NAD(P)H or NAD(P)(+) as cofactor. The enzyme activities associated with the different 17beta-HSD isoforms are widespread in human tissues, not only in classic steroidogenic tissues, such as the testis, ovary, and placenta, but also in a large series of peripheral intracrine tissues. In the nineties, several new types of 17beta-HSD were reported, indicating that a fine regulation is carried out. More importantly, each type of 17beta-HSD has a selective substrate affinity, directional (reductive or oxidative) activity in intact cells, and a particular tissue distribution. These findings are important for understanding the mode of action of the 17beta-HSD family. From a therapeutic point of view, this means that selectivity of drug action could be achieved by targeting a particular 17beta-HSD isozyme. Consequently, each study that leads to better knowledge of the inhibition of 17beta-HSDs deserves attention from scientists working in this and related fields. Being involved in the last step of the biosynthesis of sex steroids from cholesterol, the 17beta-HSD family constitutes an interesting target for controlling the concentration of estrogens and androgens. Thus, inhibitors of 17beta-HSDs are useful tools to elucidate the role of these enzymes in particular biological systems or for a therapeutic purpose, especially to block the formation of active hydroxysteroids that stimulate estrogeno-sensitive pathologies (breast, ovarian, and endometrium cancers) and androgeno-sensitive pathologies (prostate cancer, benign prostatic hyperplasia, acne, hirsutism, etc). Few review articles have however focussed on 17beta-HSD inhibitors although this family of steroidogenic enzymes includes interesting therapeutic targets for the control of several diseases. Furthermore, inhibitors of 17beta-HSDs constitute a growing field in biomedical research and there is a need for an exhaustive review on this topic. In addition to giving an up-to-date description of inhibitors of all 17beta-HSD isoforms (types 1-8), the present review will also address, when possible, the isoform selectivity and residual estrogenic or androgenic activity often associated with steroidal inhibitors.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
