5α-reductase-in-1

5α-reductase-IN-1 is a potent inhibitor of the enzyme 5α-reductase. This compound is primarily employed in research studies to investigate its potential efficacy in treating patterned alopecia. It is commonly used in combination with minoxidil, a well-known treatment for hair loss.

Bexlosteride (LY300502), a benzoquinolinone derivative, functions as a human type I 5α-reductase inhibitor. It demonstrates metabolic inhibition, antiproliferative, and antisecretory activities specifically in LNCaP human prostatic adenocarcinoma cell cultures, positioning it as a potent agent for prostate cancer research [1] [2].

SRD5A1-IN-1 is an inhibitor of steroid 5α-reductase type 1 (SRD5A1, IC50 = 1.44 µM). SRD5A1-IN-1 lowers the production of dihydrotestosterone and shows a significant decrease in the SRD5A1 protein expression.

Chinese gallotannin, derived from Galla Chinensis, is a non-specific promiscuous inhibitor of various enzymes. It is a potent inhibitor of human salivary α-amylase, with a Ki value of 0.82 μg/mL. Mechanistic studies reveal that gallotannins exert their inhibitory effects through the formation of aggregates, which serve as the active species in the inhibition process. Beyond its role in carbohydrate metabolism, it exhibits inhibitory activity against telomerase, fatty acid synthase, and 5α-reductase, making it a versatile tool for research in diabetes, oncology, and metabolic disorders.

8,11-Eicosadiynoic acid, an unsaturated fatty acid, functions as a steroid 5α-reductase inhibitor and has applications in acne research [1].
