7-Isopentenyloxycoumarin (1) was isolated from Heracleum lanatum MICHX. (Umbelliferae). Compound 1 inhibited phospholipid metabolism and Epstein-Barr virus activation caused by a potent tumor promoter. In an in vivo experiment, topical application of 1 suppressed skin-tumor-formation induced by 12-O-tetradecanoylphorbol-13-acetate (TPA) in 7,12-dimethylbenz[a]anthracene (DMBA) initiated mice. A...
سرطان یکی از مهم ترین عوامل مرگ و میر در جهان می باشد که تشخیص و درمان به موقع آن از اهمیت زیادی برخوردار است. سرطان مثانه دومین سرطان شایع دستگاه ادراری-تناسلی است. کارسینومای سلول های ترنزیشنال (tcc) سلول های شبه اپی تلیالی هستند که بیش از 90% سرطان های مثانه را تشکیل می دهند. فعالیت های زیستی با ارزش کمپلکس های سالن با فلزات و همچنین ترکیبات کومارینی به اثبات رسیده است. هدف از این پژوهش بررس...
In patients with Parkinson's disease (PD), hyperactivated inflammation in the brain, particularly microglial hyperactivation in the substantia nigra (SN), is reported to be one of the triggers for the delayed loss of dopaminergic neurons and sequential motor functional impairments. We previously reported that (1) auraptene (AUR), a natural prenyloxycoumain, suppressed inflammatory responses inc...
objective(s) 7-prenyloxycoumarins including 7-isopentenyloxycoumarin, auraptene and umbelliprenin, and herniarin have been widely recognized as bioactive coumarins. this paper presents the ways to synthesis these compounds. materials and methods 7-prenyloxycoumarins were synthesized by reaction between 7-hydroxycoumarin (' m) and relevant prenyl bromides (1.5 m) in acetone at room temperat...
