Hepato- and Neurotoxicity by Ethylenethiourea

ET-02 showed significant hair growth in five weeks, outperforming minoxidil, with a non-hormonal mechanism that avoids side effects of treatments like finasteride. A phase 2 trial is planned to further assess ET-02's efficacy and safety.

ET-02, a PAI-1 inhibitor, is not proven to be more effective than Minoxidil for hair loss. Other treatments like finasteride, dutasteride, PP405, and AMP-303 are also discussed, focusing on cellular senescence and oxidative stress.

A 28 year old using a hair loss prevention protocol to restore thinning hair, which includes finasteride, dutasteride, minoxidil, stemoxydine, alopecin, nizoral shampoo and microneedling; the user is now adding pyrilutamide solution to the regimen with the hope of improving their results. RU58841 was also ordered but not yet used.

Isotretinoin may cause hair loss by increasing DHT through a precursor androgen, DHEAS. Treatments like topical antiandrogens (RU58841, pyrilutamide) and drugs increasing PPAR-y expression (pioglitazone) might prevent this 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.

ET-02 is seen as promising for addressing hair loss and graying, but PP405 is more advanced in development and has better publicity. Some users plan to use both treatments alongside minoxidil and dutasteride.
