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.
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.
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.
IGFBP‐rP1 shows potential for treating androgenic alopecia by influencing hair cycle transitions. Increasing IGF-1 levels may have similar effects to Minoxidil and 5-AR inhibitors in reducing hair loss.
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.
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.
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.
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.
Fluridil was abandoned due to its weak effectiveness and low binding affinity to the androgen receptor, making it less competitive against DHT and testosterone. Users discuss its limited results compared to other treatments like pyrilutamide and RU58841.
Pyrilutamide is believed to be more effective than RU58841 and 1 mg finasteride in treating hair loss, with no systemic hormonal effects and the potential to block more than 31% of scalp DHT. It may also antagonize scalp testosterone due to its action as an androgen receptorantagonist.
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.
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.
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.
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.
Pyrilutamide, a nonsteroidal antiandrogen drug under development for the potential treatment of androgenic alopecia. The conversation discusses its binding affinity to the androgen receptor and the timeline for possible availability after trials are completed in the United States and China.
The conversation is about considering pyrilutamide 1% as an alternative treatment for hair loss due to intolerance to 5-alpha reductase inhibitors. Some users suggest it might be effective, while others view it as a temporary solution.
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.
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 user experienced side effects from low-dose topical finasteride and is considering using clascoterone (CB-03-01) despite concerns about its risks and cost. They seek advice on its effectiveness and potential side effects compared to other treatments like alfatradiol and fluridil.
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.
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.
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.
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.
Clascoterone in Winlevi, a topical AR antagonist, is being re-examined due to concerns about HPA axis suppression in adolescents, but it's unlikely to be banned for adult use in androgenetic alopecia (AGA). The European Medicines Agency recommended refusing Winlevi for acne vulgaris, but this may not affect Breezula's approval for AGA.
The user has been using finasteride for hair loss and is considering adding RU58841. They ask about RU58841's effectiveness, potential heart side effects, duration of action, dosage increase over time, transitioning to GT20029, and where to find the liquid form.
Hair loss treatments RU55841, CB-03-01, and Eucapil were discussed, with concerns about needing increased dosages over time and potential side effects. A user suggested that CB's results could be due to various factors and that combining it with finasteride might slow down any upregulation.
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.
