Glossary Steroid 5 Alpha-Reductase 2

enzyme converting testosterone to potent androgen dihydrotestosterone (DHT)

Steroid 5 Alpha-Reductase 2 (also known as 5α-Reductase Type 2 or SRD5A2) is an enzyme that converts testosterone into dihydrotestosterone (DHT), a more potent androgen. This enzyme plays a crucial role in the development of male characteristics and is also implicated in conditions like male pattern baldness and benign prostatic hyperplasia.

Natural Product-Inspired Bis(Trifluoromethyl) Phenyl Hydroxycinnamate Derivatives as Promising Nonsteroidal Inhibitors of Human Steroid 5α-Reductase Type-1: Synthesis, In Vitro, and In Silico Studies

research Natural Product-Inspired Bis(trifluoromethyl) Phenyl Hydroxycinnamate Derivatives as Promising Nonsteroidal Inhibitors of Human Steroid 5α-Reductase Type-1: Synthesis, In Vitro, and In Silico Studies

August 2025 in “ACS Omega”

This study synthesized and evaluated hydroxycinnamate derivatives for their ability to inhibit human SRD5A1, finding that three compounds showed significant inhibitory activity and low cytotoxicity. Compound 10a notably reduced SRD5A1 protein expression in cells, suggesting potential for nonsteroidal treatment of androgen-related conditions.

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 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 What About Phytosterol Alternatives - Rice Bran Oil - Natural DHT Blockers

3 upvotes 2 years ago

The conversation discusses natural DHT blockers like rice bran oil, which may reduce 5α-reductase activity similarly to Minoxidil and Dutasteride. One user argues that finasteride is more reliable and effective than natural alternatives.

community Alternatives/unorthodox hairloss protocols to the big three

in Chat 1 upvotes 7 months ago

The conversation discusses alternative and unorthodox hair loss treatments, including RU58841, nandrolone, and dianabol, as well as theoretical approaches involving high doses of estrogen and selective estrogen receptor modulators. These methods are considered extreme and potentially harmful but are explored for those unable to tolerate traditional 5-alpha reductase inhibitors.

community Thoughts on this hair product mix?

22 upvotes 2 months ago

The user is using a combination of 6% minoxidil, 0.3% finasteride spray in the morning, and 5% RU58841 in the evening for hair loss, considering it an aggressive approach. They are concerned about absorption issues and prefer topical treatments to avoid systemic side effects, especially while using anabolic steroids.
