5 Alpha-reductase inhibition assay: 5α -reductase is a membrane protein that localizes on the microsomes of target cells and plays an important role in the development of androgenic alopecia. After androgen binding to the receptor, complex enzymatic reactions occur, indirectly altering hair growth processes. There are 3 isozymes for 5α -reductase, i.e., types I, II, III. Type i 5 alpha-reductase is present in skin tissues such as sebaceous glands, sweat glands, papilla cells, fibroblasts, epidermal keratinocytes, hair follicle keratinocytes, etc. And type II 5 alpha-reductase is mainly present in tissues such as the prostate, reproductive skin, epididymis, seminal vesicles, etc. The conversion of testosterone to Dihydrotestosterone (DHT) depending on reduced coenzyme ii, high levels of dihydrotestosterone are prone to androgen-dependent diseases, and down-regulation of androgen levels by inhibiting 5α -reductase activity is an important method for treating androgenic alopecia. 5 alpha-reductase inhibitors have the advantage of selectively blocking dihydrotestosterone synthesis without affecting normal testosterone levels and physiological function. The 5 alpha-reductase inhibitors currently studied can be classified into natural plant-derived components, chemically synthesized steroids, pyridines, quinolinones, phenoxybutanoic acid compounds. Can screen high-efficiency inhibitor by taking 5 alpha-reductase activity as a target spot.
