متن کاملThe Antioxidant Activity of New Coumarin Derivatives
The antioxidant activity of two synthesized coumarins namely, N-(4,7-dioxo-2- phenyl-1,3-oxazepin-3(2H,4H,7H)-yl)-2-(2-oxo-2H-chromen-4-yloxy)acetamide 5 and N-(4-oxo-2-phenylthiazolidin-3-yl)-2-(2-oxo-2H-chromen-4-yloxy)acetamide 6 were studied with the DPPH, hydrogen peroxide and nitric oxide radical methods and compared with the known antioxidant ascorbic acid. Compounds 5 and 6 were synthes...
متن کاملAntioxidant Evaluation of Some Coumarin Derivatives
The present study evaluated the antioxidant potential of 28 coumarin derivatives, using three antioxidant assays: DPPH inhibition, total reducing power and NO inhibition. Out of the tested compounds, the most active DPPH free radicals scavengers were the coumarin hydrazide derivatives. These substances were also the only ones among the investigated derivatives that exhibited a moderate reducing...
متن کامل[New coumarin derivatives with expected biological activity].
A number of novel 3-bromo-4-methyl-7-methoxy-8-amino substituted coumarins and 2-substituted 7-bromo-6-methyl-8H-pyrano-benzimidazoles, benzoxazoles and/or benzoxazine-8-ones were synthesized for the purpose of pharmacological evaluation. Some representative compounds showed antitumor activity in vitro on Ehrlich ascites carcinoma in the preliminary testing.

عفونت و تهاجم ارگانیسم های انگلی به بدن، عامل اصلی بیماری و مرگ انسانها از آغاز بشریت بوده است . در حقیقت بسیاری از اشکال حیات بدون غلبه بر ارگانیسم های زنده دیگر، قادر به ادامه زندگی نخواهند بود. انسانها معمولا مستعد تهاجم ارگانیسم های کوچکتری مانند کرمها، آمیب ها، قارچها، باکتریها و ویروسها هستند. این عوامل مکان خاصی را در بدن انتخاب کرده، مواد ضروری لازم برای حیات و تکثیر خود را دریافت نموده...
