Osthenol 是一种前酰化香豆素，从独活干根中分离得到。它对重组 hMAO-A 具有潜在的选择性抑制作用，IC50=0.74 μM，对hMAO-A和hMAO-B表现出较高的选择性指数。它是一种可逆的，选择性的竞争性人单胺氧化酶-A(hMAO-A)抑制剂 (Ki=0.26 μM)。

Osthenol is a natural product, and is selective, reversible, and competitive human monoamine oxidase-A (hMAO-A) inhibitor (Ki=0.26 μM).It shows antitumor-promoting activity, it also has antifungal and antibacterial activities.

The constituents were separated by column chromatography, and their structures were elucidated by spectroscopic data analyses. The isolated compounds were evaluated for their cytoxic activities by MTT method. Eleven compounds were isolated and identified as osthole (1), bergaptan (2), xanthotoxol (3), xanthotoxin (4), imperatorin (5), isopimpinellin (6), Osthenol (7), psoralen (8), 5,7-dimethoxycoumarin (9), oxypeucedaninhydrate (10), and swietenocoumarin F (11). Compounds 7, 9-11 were isolated from the Cnidium genus for the first time[1]
