[ 1 ] - Biological Evaluation of a Siliconized Analog of Clofibrate (Silafibrate) in Rodents
Silicon is the element very similar to carbon, and bioactive siliconized compounds have therefore received much attention. Siliconization of a compound enhances its biological activities. In the present study the hypolipidemic effect and toxicity of clofibrate and its siliconized analog, silafibrate, were compared. The experiments were performed in hypercholesterolemicWistar rats. Animals recei...
[ 2 ] - Synthesis of a Novel Siliconized Analog of Clofibrate (Silafibrate) and Comparison of their Anti-inflammatory Activities
Fibrates, as hypolipidemic drugs known as agonists of peroxisome proliferator-activated receptors, diminish inflammatory responses. Studies have shown that incorporation of a silicon atom into a drug structure improves its pharmacological potency, modifies its selectivity toward a given target, or changes its metabolic rate, in addition to increasing the lipophilicity of the compounds. A si...

[ 5 ] - مروری بر رنگدانههای طبیعی و روشهای استخراج آنها
رنگدانهها در حقیقت ترکیبات شیمیایی هستند که نور خورشید را در گستره طول موج مرئی جذب مینمایند. در گیاهان چهار گروه اصلی رنگدانه شامل کلروفیلها، کاروتنوئیدها، فلاونویدها، و آنتوسیانینها وجود دارند و دارای خصوصیات و زیرمجموعههای متفاوتی میباشند. کلروفیلها و کاروتنوئیدها رنگدانههای نامحلول در آب بوده و در اندامکهای سلولها یافت میشوند، اما فلاونویدها رنگدانههای محلول در آب میباشند...
[ 6 ] - مروری بر روشهای سنتز نانوداتهای کربن و بررسی خصوصیات نشری آنها
کربن نانوداتها (کربن داتها) نسلی جدید از ساختارهای نانوکربنی (فولرنها، نانولولههای کربنی، گرافنها) هستند که تاکنون شناخته شدهاند. این نقاط کوانتومی کربنی دارای سطوح اثرناپذیری میباشند که به دلیل پایداری بسیار زیاد نسبت به رنگ پریدگی دربرابر تابش نور، زیست سازگاری، سمیت پایین، صرفه اقتصادی، و فراوانی مواد اولیه آن در طبیعت توجهات بسیاری را به خود جلب نمودهاند. عموماً کربن نانوداتها حاوی ...
