Screening of 5alpha-Reductase Inhibition and Comedolytic Effects from Natural Products

The antibacterial activity against Propionibacterium acnes (P. acnes), 5alpha-reductase inhibition and comedolytic effects are the important pharmacological target sites of antiacne drugs. We previously reported on the antibacterial activities against P. acnes by natural products. In the present study the screening of 5alpha-reductase inhibition and comedolytic effects from natural products were performed. Seven natural products such as Angelica koreana Sophora flavescens, Prunus persica, Bombyx mori, Areca catechu, Galla rhois and Gleditschia koraiensis perfectly inhibited the activity of 5alpha-reductase at the concentration of 0.01% (w/v). Sixteen natural products which were shown to have the potent antibacterial activities against P.acnes or 5alpha-reductase inhibition activities were assayed for the comedolytic test. In the results of comedolytic effects on experimentally-induced comedones (EIC), Sophora flavescens showed the strongest comedolytic effect on EIC, and Polygonum cuspidatum and Angelica koreana showed stronger comedolytic effects on EIC than azelaic acid used for a positive control at the concentration of 3% (w/v). These results suggest that several natural products including Sophora flavescens can be developed as noble antiacne agents.
