Umbelliprenin is a prenylated compound, which belongs to the class of sesquiterpene coumarins. It is extracted from dried roots of Ferula szwitsiana collected from the mountains of Golestan forest (Golestan Province, north of Iran). Induction of apoptosis in Jurkat T-CLL cells has been previously shown. In this study, effect of umbelliprenin on proapoptotic caspases (caspase-8 and -9) and antia...

[ 5 ] - Umbelliprenin Induces Apoptosis in CLL Cell Lines

    Chronic lymphocytic leukemia (CLL) remains an incurable disease that requires innovative new approaches to improve therapeutic outcome. Many Ferula species, including F. asa-foetida, synthesize terpenyloxy coumarins. One of these coumarins is umbelliprenin, which has been implicated with induction of apoptosis in some cancer cell lines.     In this study induction of apoptosis by umbellipre...

[ 11 ] - اثر حفاظت نورونی عصاره آبی زرشک (Berberis vulgaris L.) در مدل بیماری پارکینسون در موش صحرایی نر

مقدمه: بیماری پارکینسون، تحلیل نورون‌های دوپامینی در ساختمان متراکم جسم سیاه و دیگر نواحی ساقه مغز است. استرس اکسیداتیو نقش اصلی را در مرگ نرون‌ها در این بیماری بازی می‌کند. مهارکنندگان ACE (آنزیم مبدل آنژیوتانسین) نقش ثابت شده‌ای در جلوگیری از استرس اکسیداتیو دارند. زرشک یک مهارکننده ACE شناخته شده است. هدف: هدف این تحقیق بررسی عصاره آبی زرشک در درمان بیماری پارکینسون است. روش بررسی: 32 موش...

[ 12 ] - بررسی گیاهان دارویی مورد استفاده در طب سنتی ایران برای درمان فشار خون از طریق بررسی قدرت مهارکنندگی فعالیت ACE

مقدمه: آنزیم مبدل آنژیوتانسین (ACE)، اگزوپپتیدازی است که باعث تبدیل آنژیوتانسین I به II می‌شود. آنژیوتانسین II سبب انقباض عروق و ترشح آلدسترون شده و با تجزیه برادی‌کینین باعث بی‌اثر شدن آن می‌گردد. به این ترتیب ACE نقش مهمی در تنظیم فشار خون بازی می‌کند. هدف: جستجو به دنبال داروهایی با اثرات ضد فشار خون در طب سنتی جهت پیدا کردن مهارکنندگان ACE از گونه‌های گیاهی مورد مصرف در طب سنتی ایران به عن...
