واکنش ترکیبات n -(پاراتولوئن سولفونیل) (آریلوکسی) کربیمیدویل آزید(142 - 139 ) با سیکلوهگزن در حلال استونیتریل خشک ، در شرایط رفلاکس مورد بررسی قرار گرفت . محصولات بدست آمده(147 - 144 ) با ساختمانهای پیشنهادی مورد نظر مطابقت نداشتند. با اطلاعات موجود به نظر می رسد که اکسیژن هوا و همینطور استونیتریل وارد سیستم شده و روند کلی واکنش را تغییر داده باشد. تایید ساختار ترکیبات (147 - 144 ) بدلیل عدم دس...
Previous studies have demonstrated that berberine decreases N-acetyltransferase (NAT) activity in human leukemia HL-60 cells, however, NAT gene expression has not been investigated. In this study, berberine was selected for testing the inhibition of N-acetylation of 2-aminofluorene (AF) and NAT gene expression in human HL-60 cells. The N-acetylation of AF was determined and quantitated by high ...
The present research was designed to explore the anxiolytic-like activity of a novel 5-HT3 receptor antagonist (60) in experimental mouse models of anxiety. The anxiolytic activity of '6o' at (1 and 2 mg/kg, ip) was evaluated in mice by using a battery of behavioural tests of anxiety such as elevated plus maze (EPM), light/dark aversion test, hole board (HB) and open field test (OFT) with diaze...
Promyelocytic leukemic HL-60 cells were incubated with different fatty acids. Arachidonic acid (AA; 20:4, n-6) and eicosapentaenoic acid (EPA; 20:5, n-3) were the most potent inhibitors of proliferation in a dose-dependent way. Retinoic acid (RA) was used as a positive control. Inhibitors of cyclooxygenase and lipoxygenase or addition of antioxidants did not influence the effect of EPA or AA on...
