In addition to the antiflatulent, emollient, antifungal, antihemorrhoidal, antioxidant, anthelmintic effects, Prangos species have been used to stop bleeding and for the treatment of wounds and scars in central Asia and Turkey. In the present study, the compounds were isolated using chromatographic methods, and their structures were identified by H-1 NMR and direct comparison with the reference compounds where available. Fifteen known coumarins were isolated from the dichloromethane extract as osthol, murraol, auraptenol, peroxyauraptenol, 4'-senecioiloxyosthol, meranzin hydrate, scopoletin, umbelliferone, isoimperatorin, oxypeucedanin, oxypeucedanin hydrate, oxypeucedanin methanolate, gosferol, psoralen, and marmesin. The cytotoxic activities of all isolated compounds from dichloromethane extract of P. turcica roots were evaluated using MTT assay on human adenocarcinoma (prostate PC-3) cells. 4'-senecioiloxyosthol, oxypeucedanin methanolate, gosferol, psoralen, peroxyauraptenol and marmesin were tested for the first time on the PC-3 cell line. Osthol and peroxyauraptenol showed the highest cytotoxic activity with IC50 values of 65 and 72 mu g/mL, respectively. Additionally, auraptenol, scopoletin, gosferol, psoralen, 4'-senecioiloxyosthol and dichloromethane extract of root part (Pt/R/DCM) demonstrated moderate to low cytotoxic activity. Consequently, the most potent compounds, osthol and peroxyauraptenol, may be used as a lead compound to develop effective drug substances to treat prostate cancer.
