The conversation discusses Fevipiprant, an asthma drug that may block CRTH2 and potentially stop male pattern baldness (MPB) without inhibiting DHT. It also mentions the use of finasteride and dutasteride for hair loss.
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.
RU58841 lacks FDA approval due to financial and safety concerns, including potential cardiological side effects. The company abandoned further research, and users report adverse effects like heart palpitations and gynecomastia.
Comparing the effectiveness of RU58841, Pyrilutamide and CB-03-01 as treatments for hair loss, with people discussing different aspects such as binding affinity, time of inhibition, safety data and cost.
Alfatradiol is discussed as a weak 5ARI and estrogen, not as effective as minoxidil, RU58841, or CB-03-01, but a safe alternative for those who can't use finasteride. Users express frustration over the lack of strong FDA-approved topical antiandrogens for hair loss.
User discusses group buy for finerenone, a third-gen mineralocorticoid antagonist for hair loss treatment. Finerenone inhibits TGFb, NOX, and ROS, and improves renal and cardiac function; topical dose should be no more than 10mg per day.
The conversation is about comparing the effectiveness of fluridil and clascoterone in preventing hair loss and inquiring about their use as standalone treatments. There is a question about the concentration of the fluridil brand for efficacy.
Fluridil may decrease the number of androgen receptors in hair follicles by up to 95%. This suggests a different action mechanism from other non-steroidal antiandrogens like RU58841, indicating they might be used together.
The efficacy of degrading the androgen receptor through dermal application in DP cells, a delivery system for topical drugs that involves dissolving microneedles, and rosemary oil as an alternative anti-androgen.
Pyrilutamide and RU58841 are androgen receptorantagonists that block receptors without significantly reducing testosterone or DHT levels. Any indirect effect on androgen levels is likely negligible.
GT20029 and pyrilutamide are both androgen antagonists but work differently; GT20029 degrades the androgen receptor, while pyrilutamide blocks DHT from binding. GT20029 is expected to have similar efficacy to CosmeRNA.
Topical androgen receptorantagonists may not be necessary if 5-AR inhibitors like finasteride or dutasteride effectively reduce DHT levels. Combining a 5-AR inhibitor with a topical androgen antagonist could potentially enhance treatment, but oral use of androgen antagonists is too risky due to severe side effects.
User tried oral finasteride, topical finasteride, topical dutasteride, and RU58841 but experienced side effects. They discuss upcoming treatments like clascoterone, pyrilutamide, gt20029, and KY19382 as potential options.
Pyrilutamide is officially available for purchase, and users suggest Fluridil as an alternative topical anti-androgen. Some users report positive results with pyrilutamide from Koshine.
RU and Pyri block androgen receptors to prevent hair loss but may also hinder hair regrowth since they prevent testosterone, which can stimulate hair growth, from binding to these receptors. The user is questioning if this understanding is correct.
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.
The relative strength of Pyrilutamide compared to RU58841 in terms of androgen receptor binding affinity. It has been noted that Pyrilutamide is 4x stronger than RU58841, with a higher binding affinity than DHT itself.
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.
RU58841 is a strong non-steroidal antiandrogen for hair loss but may cause cardiovascular issues in some users. Alternatives like Pyrilutamide and Breezula are suggested due to better safety profiles and lower systemic risks.
Pyrilutamide is a selective AR antagonist with a high binding affinity, making it effective in competing with DHT for androgen receptors. The 1% concentration is more effective than the 0.5%, but the latter may suffice for mild hair loss; the drug is considered a good option for those avoiding 5AR blockers due to side effects.
Pyrilutamide is considered by some as an alternative for those avoiding 5AR inhibitors like finasteride and dutasteride, but opinions on its effectiveness vary. Some users report similar results with fluridil and pyrilutamide, while others find pyrilutamide less effective compared to prescription treatments.
Exploring different treatments for hair loss, such as cosmeRNA and HMI-115 which are small interference messenger RNA that inhibits the DHT receptor and an antibody that binds to the prolactin (PRL) receptor respectively; and researching mechanism and environment of hyperresponders.
Hair loss treatments, specifically the use of Alfatradiol as an over-the-counter topical 5AR inhibitor that has been shown to be effective in stopping hair loss without side effects. Other treatments discussed include Minoxidil, finasteride and RU58841.
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.
Researching and developing an effective local antagonist to block the androgen receptors for hair loss, as opposed to using DHT synthesis inhibitors that lower serum DHT levels. Several treatments such as CosmeRNA and Pyrilutamide are currently in development or undergoing trials.
The user is considering using CB or clascoterone for hair loss, potentially as an alternative to RU. They're also contemplating asking a dermatologist for topical clascoterone cream to apply to their temple.
RU58841 and Minoxidil can cause heart-related side effects like chest pain and heart racing. Pyrilutamide is suggested as a safer alternative, though it's new and costly.
