[ 1 ] - بررسی مکانیسم مهاری ترکیب اوژنیل آدامانتات نسبت به آنزیم 15- لیپواکسیژناز
هدف: آنزیمهای لیپواکسیژناز از دسته پروتئین های آهن دار غیر همی هستند که مسئول پراکسیداسیون اسید های چرب غیر اشباع در گیاهان و حیوانات می باشند. اهمیت فعالیت این آنزیمها در بدن پستانداران و نقش آنها در ایجاد حساسیت ها، التهابها و حتی تشکیل برخی از سرطانها به اثبات رسیده است. از این رو مطالعه در مورد جزئیات مکانیسمی این دسته از آنزیمها و متابولیسم محصولات پراکسیدی آنها و همچنین سنتز مهار کننده ه...
[ 2 ] - Design and synthesis of new esters of terpenoid alcohols as 15-lipoxygenase inhibitors
Objective(s): 15-Lipoxygenases are one of the iron-containing proteins capable of performing peroxidation of unsaturated fatty acids in animals and plants. The critical role of enzymes in the formation of inflammations, sensitivities, and some cancers has been demonstrated in mammals. The importance of enzymes has led to the development of mechanistic studies, product analysis, and synthesis of ...
[ 3 ] - Inotropic and chronotropic effects of new cilostamide derivatives on isolated rat atria
Introduction: It was shown in a previous study, that MCPIP, a cilostamide derivative, increased atrial contraction force without changing contraction rate. To improve this property, two new derivatives of cilostamide were synthesized and their effects on PDE3 activity and isolated rat atria contraction were investigated. Methods: The inhibitory effect of each compound on PDE3 enzyme was dete...
[ 4 ] - Design, synthesis, and SAR study of isopropoxy allylbenzene derivatives as 15-lipoxygenase inhibitors
Objective(s): Allylbenzenes have been recently developed as inhibitors of lipoxygenases. They decrease peroxidation activity via mimicking 1,4-unsaturated bonds of fatty acids by their allyl portion. We designed and synthesized new derivatives of allyl benzenes (6a-f) with isopropoxy and amide substituents at ortho and meta positions towards allyl group, respectively. ...
