Synthesis and Biological Evaluation of 4-(4-(Alkyl- and Phenylaminocarbonyl)benzoyl)benzoic Acid Derivatives as Non-Steroidal Inhibitors of Steroid 5α-Reductase Isozymes 1 and 2

research Synthesis and Biological Evaluation of 4-(4-(Alkyl-and Phenylaminocarbonyl)benzoyl)benzoic Acid Derivatives as Non-steroidal Inhibitors of Steroid 5α-Reductase Isozymes 1 and 2

8 citations , March 2002 in “Archiv Der Pharmazie”

In this study, 4-(4-(phenylaminocarbonyl)benzoyl) benzoic acid exhibited the strongest inhibitory activity against the human type 2 steroid 5α-reductase isozyme among the compounds tested.

research Immunolocalization of 5α-Reductase Isozymes in Acne Lesions and Normal Skin

45 citations , September 2000 in “Archives of dermatology”

This study found that 5alpha-reductase type 1 localizes specifically to sebaceous glands in both normal and acne follicles, suggesting its role in sebum regulation.

research The Rationale for Inhibiting 5α-Reductase Isoenzymes in the Prevention and Treatment of Prostate Cancer

108 citations , February 2008 in “The Journal of urology/The journal of urology”

This review discusses the rationale for targeting 5α-reductase isoenzymes in prostate cancer prevention and treatment, highlighting the potential benefits of using inhibitors like dutasteride and finasteride but reports no new experimental results.

research Identification of 5α-reductase isoenzymes in canine skin

4 citations , July 2015 in “Veterinary Dermatology”

This study identified the expression of 5αR1 and 5αR3 enzymes in canine skin, which may advance understanding and treatment of alopecia X.

research Extensive Challenges and Pending Advances in the Study of 5-Alpha-Reductase Isoenzymes. A Literature Review

August 2024 in “Latin American Journal of Development”

In this review, the authors highlight the involvement of the 5α-reductase enzyme family in androgen-dependent disorders, noting the discovery of a novel isoform, SRD5A3, which is overexpressed in cancers with poor prognosis.

community Did anybody use beta sisterol for hair loss? I saw in many articles in the internet that said that beta sisterol blocks dht by inhibiting 5a reductase type 2 enzyme and some reviews of people who said that it worked better than saw palmetto in terms of stoping hair loss and helping prostate.

in Research/Science 9 upvotes 3 years ago

Beta-sitosterol may inhibit 5-alpha reductase type 2 enzyme, potentially reducing DHT levels and promoting hair growth, similar to finasteride but possibly with fewer side effects. Its effectiveness and side effects compared to other treatments like saw palmetto and finasteride remain uncertain due to limited research.

community Was scared to try fin and jumped straight to 2.5mg Dut?

36 upvotes 4 days ago

The user started with oral minoxidil and switched to 2.5mg dutasteride, experiencing significant hair growth without side effects. They believe dutasteride has fewer side effects than finasteride due to its action on both type 1 and 2 5-alpha reductase enzymes.

community [Research Breakdown] The Genetic Edge: Unpacking Dutasteride vs Finasteride Potency

6 upvotes 2 weeks ago

Dutasteride is more effective than finasteride for increasing hair count, but finasteride is considered safer for long-term use unless hair loss is very aggressive. Starting with finasteride is recommended due to its effectiveness and safety profile.

community Age 18 vs Age 25, the importance of starting early

886 upvotes 1 year ago

An 18-year-old began using Finasteride and Topical Minoxidil for hair loss, later switching to Oral Minoxidil and Dutasteride by age 25. The conversation emphasizes early treatment, potential side effects, and differing opinions on medication effectiveness.

community New Research- Creatine Increasing Scalp DHT Without Corresponding Serum DHT Increase

121 upvotes 2 years ago

Creatine may increase scalp DHT without affecting serum DHT, potentially speeding up male pattern baldness (MPB) for those genetically prone. Treatments mentioned include Minoxidil, finasteride, and RU58841.

learn Overview

learn procapil

Want to stop hormonal hair loss without touching your hormone levels? Procapil could block the enzyme doing the damage. Procapil's supplier describes it as inhibiting 5-alpha reductase at the scalp without changing hormone levels, but the published support is cell and animal work plus one small human study of a caffeine-plus-Procapil formula. It is a cosmetic ingredient, not an approved hair-loss treatment, and no trial has compared it with finasteride or minoxidil.

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.
