N-isopropyltheobromine and N-sec-butyltheobromine were synthesized via nucleophilic substitution reaction by reacting theobromine and two kind of alkyl bromide derivatives, i.e. isopropyl bromide and sec-butyl bromide using N, Ndimethylformamide (DMF) as a solvent. Yields (N-isopropyltheobromine = 7.70%; N-sec-butyltheobromine = 5.89%) were slightly less than the previous synthesis which used e...
Abstract Aims and Background: Electroconvulsive therapy (ECT) as a method of treatment in severe psychological disorders results in autonomic system stimulation and hemodynamic complications. To relieve these complications especially severe bradycardia and asystole, some authors usually premedicate patients with anticholinergic drugs .The aim of this study was to determine and compare ...
The production of lung adenomas in strain A mice following multiple injections of 17 alkyl halides and of 3 base analogs was investigated. A slight but significant increase in the average number of lung tumors per mouse was noted following the administration of methyl iodide, n and i-propyl iodide, secand tert-butyl chloride, i-, sec-, and tert-butyl bromide, and nand sec-butyl iodide. The admi...
The reactivity of microsolvated fluoride ions, F (CH3OH)0–2, with methyl, ethyl, n-propyl, and t-butyl bromide is evaluated over a broad range of temperatures. Significant decreases in reactivity are observed as either solvation or temperature increases. Increasing solvation increases sensitivity to the reaction barrier as revealed by a larger temperature dependence. These reactions are dominat...
AIM To determine the effects of hyoscine-N-butyl bromide (HBB) rectal suppository on labor progress in primigravid women. METHODS A randomized double-blind placebo-controlled clinical trial was carried out on 130 primigravid women admitted for spontaneous labor. The women were recruited based on the inclusion and exclusion criteria and randomized into the experimental (n=65) and control group...
