research In Silico Structure-Based Drug Design Approach To Evaluate Quercetin And Kaempferol As Dual Inhibitors Of Jak3 Kinase And 5-Alpha Reductase Type II with ADMET Profiling

June 2026 in “Zenodo (CERN European Organization for Nuclear Research)”

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.

research In Silico Structure-Based Drug Design Approach To Evaluate Quercetin And Kaempferol As Dual Inhibitors Of Jak3 Kinase And 5-Alpha Reductase Type II with ADMET Profiling

June 2026 in “Zenodo (CERN European Organization for Nuclear Research)”

This study used molecular docking to analyze the binding affinities of quercetin and kaempferol, plant-derived flavonoids, showing they have promising interaction profiles with JAK3 kinase and moderate binding with 5-alpha reductase type 2, suggesting potential as topical treatments for androgenetic alopecia.

research Nonsteroidal inhibitors of human type I steroid 5-.alpha.-reductase

89 citations , February 1993 in “Journal of Medicinal Chemistry”

This research article focuses on nonsteroidal inhibitors of human type I steroid 5-alpha-reductase but reports no new results.

research Expression and Activity Assay of Human Steroid 5 Alpha-Reductase Type II in CHO Cells

January 2004 in “Pharmaceutical biotechnology”

This study found that finasteride effectively inhibits the enzymatic activity of human steroid 5 alpha reductase type II in newly established CHO cell lines.

research Synthesis and in Vitro Evaluation of 4-Substituted N-(1,1-Dimethylethyl)-3-oxo-4-androstene-17.beta.-carboxamides as 5.alpha.-Reductase Inhibitors and Antiandrogens

12 citations , April 1995 in “Journal of Medicinal Chemistry”

In this study, 4-substituted N-(1,1-dimethylethyl)-3-oxo-4-androstene-17.beta.-carboxamides were synthesized and evaluated in vitro as potential 5 alpha-reductase inhibitors and antiandrogens.

community FCE 28260: A Forgotten 5α-Reductase Inhibitor

in Research 330 upvotes 2 years ago

FCE 28260 (PNU 156765), an under-explored 5α-reductase inhibitor, showcases promising results in research by Giudici et al., outperforming well-known treatments like Finasteride in reducing the conversion of testosterone to DHT. Its superior efficacy, demonstrated through lower IC50 values in both natural and human recombinant enzyme studies, suggests it could offer more effective management of DHT-related conditions. Additionally, its lower molecular weight hints at better potential for topical application, potentially offering advantages in treating conditions such as androgenic alopecia. Despite its potential, it has not advanced in development, possibly due to financial limitations, leaving its therapeutic prospects and side effect profile largely unexplored.

community Seeking Advice on Norwood 3 Hairline at Age 15

in Basic Questions 533 upvotes 10 months ago

A 15-year-old is concerned about hair loss, possibly at Norwood 2 or 3, and is using shampoos and conditioners recommended by a trichologist. Suggestions include considering topical minoxidil and consulting a doctor about topical anti-DHT treatments like finasteride or RU58841, but avoiding 5-alpha-reductase inhibitors at this age.

community Dutasteride might be better for your hairline. Some people have more type 1 5AR activity in their scalp than others.

in Finasteride/Dutasteride 52 upvotes 3 years ago

Dutasteride might be better for hairline due to varying levels of 5AR activity in scalps. Genetic tests can determine if finasteride is enough or if dutasteride is needed.

community I stopped finasteride and minoxidil and I regret it

in Progress Pictures 251 upvotes 4 months ago

The user regrets stopping finasteride and minoxidil due to increased hair loss. They have resumed these treatments and are considering a hair transplant.

community UPDATE: now 5 months on Dut and continuing to regress aggressively

in Finasteride/Dutasteride 218 upvotes 1 year ago

The user is experiencing significant hair loss after switching from finasteride to dutasteride for five months. Suggestions include that the hair loss might be a normal shedding phase, with some recommending continuing the treatment for up to 24 months or considering alternatives like RU58841.

learn Finasteride

Popular 5-alpha reductase inhibitor that lowers DHT, taken as a pill or used topically

learn Dutasteride

5-alpha reductase inhibitor that blocks both enzyme types, a stronger DHT blocker than finasteride

learn GT20029

Experimental topical drug designed to break down androgen receptors

learn Cyproterone

a synthetic anti-androgen and weak progestogen that inhibits DHT binding to androgen receptor

learn Fluridil

Topical anti-androgen sold as a cosmetic lotion

How is Fluridil different from other DHT blockers like finasteride? Fluridil is a topical androgen-receptor blocker applied to the scalp, while finasteride is an oral 5-alpha-reductase inhibitor that lowers DHT throughout the body. Finasteride is FDA-approved and far better studied; Fluridil rests on one 43-man trial and is not licensed as a hair-loss medicine, so its long-term safety and effect size are unknown.

learn Bicalutamide

Can bicalutamide stop DHT from shrinking your hair follicles? Bicalutamide blocks androgens at the receptor rather than lowering DHT, and some dermatologists prescribe it off-label for women with pattern hair loss, although its US label says it should not be used in women. The one randomised trial (74 women, 2025) found it added no benefit to oral minoxidil, and the drug needs liver monitoring because its label warns of severe and fatal liver injury; it is contraindicated in pregnancy.
