Hormonal Control Of 5 Alpha-Reductase Activity In Hamster Sebaceous Glands

January 1982 in “ Endocrinologia Japonica ”

Susumu Takayasu, Satoshi Itami

Studysummary This study found that castration increased 5 alpha-reductase activity in the sebaceous glands of male hamsters, but administering testosterone propionate or 5 alpha-dihydrotestosterone inhibited this effect.

community 5 alpha reductase type 1 is in brain tissue producing the main endogenous gabaergic allopregnanolone, not 2. How can finasteride as a 5ar2 lower that?

27 upvotes 1 year ago

Finasteride and dutasteride are discussed for hair loss, with concerns about their effects on neurosteroids and potential side effects like depression. Alternatives like topical estrogen and lifestyle changes are considered, with varying opinions on mental health and hair regrowth.

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 Bile Acid-Mediated DHT Dysregulation Hypothesis

in Research/Science 13 upvotes 1 year ago

Elevated bile acids can inhibit the enzyme AKR1C2, leading to increased DHT levels, which may accelerate hair loss in those predisposed to androgenetic alopecia. Treatments mentioned include topical minoxidil and finasteride.

community Does caffeine inhibit 5-α-reductase?

4 upvotes 6 years ago

Caffeine may promote hair growth and potentially inhibit 5-α-reductase activity in hair follicles, but its effectiveness and systemic impact remain unclear. Users discuss using topical caffeine solutions, with some experiencing no side effects compared to finasteride.

community Has there been any update or progress on the 3-alpha hydroxysteroid dehydrogenase hypothesis?

13 upvotes 2 months ago

The conversation discusses the hypothesis that a lack of the enzyme 3-alpha hydroxysteroid dehydrogenase (3α-HSD) on the scalp may contribute to hair loss by allowing DHT to accumulate. Despite interest in this theory, no recent research has been conducted, and current treatments like finasteride and minoxidil remain the most supported options.

community A better treatment would be a localized 5ar inhibitor that breaks down when it enters blood or leaves hair follicle

1 upvotes 1 year ago

The conversation discusses the need for a localized 5-alpha reductase inhibitor that only affects the scalp without systemic side effects, similar to pyrilutamide's approach. Current treatments like topical liposomal finasteride and dutasteride are mentioned, but concerns about their systemic effects and lack of research are highlighted.
