DISCUSSION An interaction might occur when two or more agents are taken together. The likelihood of these interactions increases when herbs or herbal products are involved due to their multicomponent nature. The clinical result of such an interaction will likely affect therapeutic outcome either positively or negatively. Meanwhile‚ effective microbial control of urinary tract infection depends on the excretion and sustenance of therapeutic concentration of antimicrobial agents in urine. The excretion

A. Goal and Purpose: Session 1: In this lab‚ we will achieve a simple Friedel-Crafts alkylation of anthracene. The choice of anthracene as an aromatic substrate stems from two considerations. First‚ there is a question of regioselectivity. Second‚ anthracene and its derivatives are highly visible under UV light. Session 2: In this lab‚ we will complete a partial conversion of 9-acetylanthracene using m-chloroperoxybenzoic acid (mCPBA). We will also determine by NMR‚ the regiochemistry of the

protecting the ketone of ethyl acetoacetate with a ketal group‚ followed by preparation and reaction with Grignard‚ then purification by extraction and recrystallization. The yield was 78.5%‚ but there are impurities present suggested by 1H-NMR‚ IR‚ and TLC. However‚ the results do indicate the desired hydroxyketone was formed. Introduction: The purpose of this multi-step lab was to synthesize 4-hydroxy-4‚4-diphenylbutan-2-one from ethyl acetoacetate. The Grignard reaction is widely used to react

Although it accounts for only 2% of your total body weight‚ the fact remains that the brain is a food-hungry organ with ten times the appetite of other organs. In order to function‚ it uses up a minimum of 20% of your daily calorie in-take.
