MK-386 reduces sebum DHT levels.

This study showed that Thujae occidentalis semen extract inhibited 5alpha-reductase type 2 in laboratory tests and reduced androgen-related hair loss in animal models, suggesting potential use for male pattern baldness.

This study found that finasteride treatment in male rats led to enduring effects on depressive-like behavior, hippocampal neurogenesis and neuroinflammation, and gut microbiota composition after withdrawal.

This study found that Puerariae Flos extract inhibited testosterone 5α-reductase and promoted hair growth in mouse models, suggesting its potential use for treating androgenic alopecia.

This study concluded that men with benign prostatic hyperplasia receiving steroid 5α-reductase inhibitors, such as dutasteride or finasteride, have a higher risk of developing new onset type 2 diabetes compared to those taking tamsulosin.

This review highlights the challenges in screening for steroid 5 alpha-reductase inhibitors and discusses significant variability in the effectiveness of finasteride and dutasteride, calling for standardized testing methods to develop safer, more specific inhibitors from herbal preparations.

In this study, finasteride dose-dependently inhibited stress-induced increases in allopregnanolone in rats, while enhancing 20alpha-reduction of progesterone without affecting 3alpha-dihydroprogesterone or 11-deoxycorticosterone levels.

This study identified LY191704 as a specific noncompetitive inhibitor of human 5 alpha-reductase type 1, which may be useful in treating endocrine disorders related to DHT overproduction.

This study found that Piper nigrum leaf extract showed in vivo anti-androgenic activity and potent 5α-reductase inhibitory effects, with piperine and (−)-cubebin identified as active components.

This study isolated new geranylated coumarins from Mammea siamensis flowers and found that several of these compounds inhibit testosterone 5α-reductase.

Dutasteride reduces DHT more effectively than finasteride.

This study found that Ficus benghalensis leaf extracts reduced the activity of 5 α-reductase II and promoted hair growth in rabbits by elongating the hair follicle's anagen phase, suggesting potential for treating hair loss.

In this study, researchers used computational methods to identify six phytochemicals from nettle, saw palmetto, and fenugreek as effective binders to 5-alpha reductase, with Jamogenin showing enhanced stability when encapsulated in lipid nanoparticles.

In this computational study, researchers identified six phytochemicals, including Jamogenin, that effectively bind to the enzyme 5-AR, potentially promoting hair growth, and found that encapsulating Jamogenin in lipid nanoparticles enhances its stability.

This integrative literature review suggests that phytotherapeutic products, like Saw palmetto and Green tea, could serve as viable alternatives to current medications like finasteride for treating androgenetic alopecia, potentially offering fewer side effects.

This article reviews the characteristics and uses of finasteride for benign prostatic hyperplasia, noting variable symptom improvement and ongoing investigation in other DHT-mediated conditions, and reports no new clinical results.

This study found that exposure to finasteride impaired spermatogenesis in male Xenopus laevis by affecting sex-specific feedback mechanisms in the hypothalamus–pituitary–gonad axis.

This study found that LY320236 is a competitive inhibitor of type I and a non-competitive inhibitor of type II steroid 5alpha-reductase, indicating its potential as a dual inhibitor with differing modes of activity.

This study found that low-dose finasteride treatment in men with premature androgenetic alopecia decreased levels of 5α-reduced steroids, which may be linked to increased depression symptoms.

In this study using a virtual screening approach, eriocitrin and silymarin were identified as potent flavonoid compounds that strongly and stably interacted with 5α-reductase type II, suggesting potential development as novel treatments for androgenic alopecia.

This study found that 60% of men with mild to moderate androgenetic alopecia showed improvement after treatment with botanically derived 5AR inhibitors, suggesting these compounds may be effective, though larger trials are needed.

Clinical studies reported that finasteride reduces scalp dihydrotestosterone levels and improves hair growth in men with androgenetic alopecia, supporting its role as a treatment option.

This study found that torilin from Torilis japonica fruit extract inhibited 5 alpha-reductase in vitro more effectively than alpha-linolenic acid but less effectively than finasteride.

This study found that components derived from Uromedic® pumpkin seeds, especially Δ7-sterols, may inhibit DHT production and AR binding, potentially benefiting prostate and bladder health by moderating these mechanisms.

This review discusses the pharmacology and clinical use of finasteride for benign prostatic hyperplasia and reports its effectiveness in reducing prostate size and symptoms, though success varies among patients.

This study found that among 17 beta-(N-ureylene-N,N'-disubstituted)-4-azasteroids, those with an N'-phenyl moiety were the most effective inhibitors of human type I 5 alpha-reductase.

This study used molecular docking to identify stiripentol as a potential new inhibitor of the SRD5A2 enzyme, which is targeted for treating androgen-related diseases; however, in vivo trials are needed to validate its efficacy.

This chapter reviews human physiological systems like the nervous and circulatory systems, discussing their roles and interactions, but it presents no new research findings.

This study found that octahydrobenzo[c]quinolizin-3-one derivatives, particularly compound 3, were potent and selective inhibitors of the enzyme 5α-reductase type 1.

In this study, quercetin and kaempferol, two plant-derived flavonoids, showed stronger binding affinities to JAK3 kinase and moderate binding to 5-alpha reductase type 2, suggesting their potential as natural treatments for androgenetic alopecia, with quercetin demonstrating suitable properties for topical application.
