,
October 2020 in “Current Drug Discovery Technologies” This study investigated various synthesized 5-reductase inhibitors and found that compound 6 had the highest anti-androgenic activity and receptor affinity compared to finasteride, showing potential due to its improved efficacy and bioavailability for further research in treating lower urinary tract symptoms.
January 2026 in “Open Science Framework” In this study, network meta-analyses were used to explore the ranking of various 5-alpha reductase inhibitor regimens on reducing dihydrotestosterone levels and to investigate whether this reduction correlates with increased total hair density in male androgenetic alopecia.
March 2010 in “The Journal of Urology” This study demonstrated that methylation of the 5-alpha reductase type 2 (5-AR2) promoter is linked to reduced expression of the 5-AR2 protein, possibly explaining resistance to Finasteride in some BPH patients.
