research Dose-dependent and long term effects of RU58841 (androgen receptor blocker) on hair growth in the bald stumptailed Macaque.

1 citations , January 1997 in “Journal of Investigative Dermatology”

In this study using a macaque model, RU58841 at a 5% concentration significantly increased hair density, thickness, and length in the frontal bald scalp over six months.

research The effect of topical RU58841 (androgen receptor blocker) combined with minoxidil on hair growth in macaque androgenetic alopecia

March 1998 in “Journal of Dermatological Science”

Combining RU58841 and minoxidil significantly increases hair growth.

research Androgen Receptor Antagonists (Antiandrogens) Structure-Activity Relationships

204 citations , February 2000 in “Current Medicinal Chemistry”

This review discusses the use of antiandrogens like flutamide and its derivatives in prostate cancer treatment and highlights the need for next-generation antiandrogens for improved efficacy; it reports no new clinical results.

research Testosterone Reduces Knee Passive Range of Motion and Expression of Relaxin Receptor Isoforms via 5α-Dihydrotestosterone and Androgen Receptor Binding

23 citations , March 2014 in “International Journal of Molecular Sciences”

The study observed that testosterone reduced knee range of motion in ovariectomized female rats, potentially by downregulating specific relaxin receptor isoforms, with its effects mediated via dihydro-testosterone.

research Highly efficient nucleophilic addition of alkyl Grignard reagents to 17-ketosteroids in the presence of cerium(III) chloride: Synthesis of 17α-propyl-17β-hydroxy-4-androsten-3-one, an androgen receptor antagonist

14 citations , February 1994 in “Tetrahedron Letters”

This study found that using anhydrous cerium(III) chloride with alkyl Grignard reagents significantly improved the addition to sterically hindered 17-ketosteroids, resulting in high yields and stereoselectivity.

community Is there a topical androgen receptor blocker so we don't have to fuck with the enzyme and destroy our allopregnanolone, but go and hit the end target straight?

in Treatment 44 upvotes 2 years ago

The conversation discusses topical androgen receptor blockers for hair loss, mentioning Clascoterone, Pyrilutamide, GT20029, and RU58841. Ketoconazole's effectiveness and application methods are also debated.

community Androgen degraders for hair loss

61 upvotes 2 years ago

The conversation discusses androgen receptor degraders for hair loss, highlighting their potential advantages over traditional AR blockers like RU58841 and pyrilutamide. Concerns about the safety and cost of these treatments are also mentioned.

community 27M Struggling with 5-Month Treatment Limit on Minoxidil and Finasteride, Seeking AR Blocker Advice

in General 111 upvotes 1 year ago

A 27-year-old male is experiencing a recurring pattern of hair loss after 5 months of using oral minoxidil and finasteride, despite initial success. He is considering using topical androgen receptor blockers like RU58841, pyrilutamide, or clascoterone to address potential androgen receptor hypersensitivity.

community How can ketoconazole shampoo block androgen receptor if it's just washed off?

60 upvotes 10 months ago

Ketoconazole shampoo is primarily used to reduce scalp fungus and inflammation, not to block DHT or androgen receptors. It may help with seborrheic dermatitis and improve scalp health, but its effects on hair loss are minimal compared to treatments like finasteride.

community Chat is this real? Compound called clascoterone

581 upvotes 9 months ago

Clascoterone shows promising results for hair regrowth in men with androgenetic alopecia, with potential FDA approval by 2026. It acts as a topical androgen receptor blocker, offering a new treatment option with minimal side effects compared to existing treatments like finasteride.

learn Fluridil

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 KX-826

Kintor Pharmaceutical: KX-826, a New Name in Hair Loss Research KX-826 (pyrilutamide) is an experimental topical androgen receptor blocker from Kintor Pharmaceutical. It is not approved as a medicine anywhere; the company reports that its China Phase III trial met its primary endpoint at 24 weeks, but the trial data has been released through corporate announcements rather than peer-reviewed journals and long-term safety is unknown.

learn Overview

learn GT20029

research compound made to degrade androgen receptors in scalp

What is GT20029 and how does it work as a topical anti-androgen for hair loss? GT20029 is a topical anti-androgen that degrades androgen receptors to combat hair loss.

learn Cyproterone

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

learn Clascoterone

a novel topical treatment that inhibits DHT on androgen receptors

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. The published evidence is retrospective case series and one small pilot study, with no randomized trial; it is a prescription drug that requires liver monitoring and is contraindicated in pregnancy.

learn Exosomes

What does Fluridil do on the scalp, and how does it block the DHT hormone? Fluridil blocks DHT by binding to androgen receptors in hair follicles, preventing hair loss.

learn Pyrilutamide

highly targeted anti-androgen that might have minimal systemic effects
