Experiment 2 Report Scaffold (Substitution Reactions, Purification, and Identification) Purpose/Introduction 1. A Sn2 reaction was conducted; this involved benzyl bromide, sodium hydroxide, an unknown compound and ethanol through reflux technique, mel-temp recordings, recrystallization, and analysis of TLC plates. 2. There was one unknown compound in the reaction that was later discovered after a series of techniques described above.
There is not a major outlier since all of the data plots touch the line of best fit. Although, the decrease in the reaction time in Figure 2 has a fairly linear slope, the amount of decrease between each water temperature differs. For example, the fall of the average reaction time between 17°C and 27°C was 0.013 seconds, while the fall of the average reaction time between 27°C and 37°C was 0.047 seconds. Thus, a relatively less sharper decrease in the average reaction time was observed between temperatures 17°C and 27°C than the decrease between temperatures 27°C and 37°C. A lower rate of decrease in the
This shows that esomeprazole is more effective in the body. The AUC decreases after consumption.iv The bioavailability of esomeprazole is 68% while the bioavailability of omeprazole is 20%. Therefore, esomeprazole is suggested to be more effective than omeprazole. Esomeprazole 20 mg and 40 mg was shown to have a better healing capability during the eighth week than omeprazole 20 mg in patients with gastroesophageal reflux disease. Over a four week therapy, it was shown that esomeprazole has very little value over omeprazole.

Thus, Artemisia absinthium administration for 60 days interrupted the weight loss in DT group compared to D group, and this may be due to improvement in insulin secretion and insulin action. The percent decrease in plasma glucose level of DT group in 60 days is because of Artemisia absinthium treatment respectively. Thus, the present study indicates that chronic treatment of diabetic rats for 2 months with Artemisia absinthium decreased the plasma glucose level to the near normal values. The plasma glucose level of NT and DT groups during the experimental period clearly indicate that Artemisia absinthium does not exhibit hypoglycemic activity; instead, it shows anti-hyperglycemic
Kidney weight at birth was decreased significantly in RFT offspring compared with control, whereas relative heart weight at week 4 was reduced significantly (p ˂ 0.05) in RFT offspring when compared with control one. During kidney development, histological examination indicated delayed nephrogenesis in RFT kidneys presented as less well-differentiated glomeruli, more connective tissue, fewer medullary rays, and immature stages in the form of S-shaped bodies. TUNEl assay showed an increase in apoptotic nuclei from RFT kidney at birth compared with control group. Electron microscopic examination showed that there was no difference between RFT and control groups in regards to proximal tubule development and glomerular filtration barrier. Stereological analysis showed a reduction by ~ 30% in nephron number of RFT animals compared with control animals.
Synthesis of 3-[5-(4-substituted) phenyl-1,3,4-oxadiazole-2yl]-2-styrylquinazoline-4(3H)-ones was carried out by following steps: Step 1: Synthesis of 4- substituted benzaldehyde semicarbazon51(2) Semicarbazide Hydrochloride (0.1M) and sodium acetate (0.2M) was added and dissolved in 15-20ml of distilled water placed in flat-bottomed flask. In a separate beaker containing required aromatic aldehyde (1) (0.1M) was dissolved in aldehyde free alcohol. This ethanolic aromatic aldehyde solution was added slowly to the solution of semicarbazide hydrochloride.
The melting point of the experimentally synthesized Aspirin product was found to be between 126-129 ˚C. This temperature range of initial to final melting point has a small and sharp temperature range of only 3˚C, which is within the acceptable limits of the 128-137˚C1 literature value for Aspirin (Acetylsalicylic Acid/2-acetoxybenzoic acid), if located slightly toward the beginning of the literature melting temperature range. Therefore, the narrow melting point range, which falls within the standard literature value range results, indicate the reliability purity of the sample. Had the melting point been higher than the literature value, but maintained a sharp melting point range, the compound could have still indicated a pure sample. A lower
The inhibitory effects of the bean extracts and EA against BwaxP mutagenicity were found to be dose-dependent. The percentages of inhibition produced against BwaxP _2 mg/plate. using 300 mg/plate of EA and for the extracts 500 mg equivalent catechin plate were 82%, 83%, 81% and 83% for EA, water extract, water+methanol extract and methanol extract, respectively. But for 1-NP mutagenicity, the inhibitory effect was shown by methanolic extract only. Hence it was reported as health-promoting food
The graph displays a negatively skewed trend, which suggests that the hypothesis was not supported. This is because the greatest percentage of caffeine (100%) did not result in the greatest reaction time, as predicted. The subjects who drank a 50% caffeinated beverage had the fastest reaction rate, taking an average of 0.39478 seconds to react. Comparatively, the subjects that drank the 100% caffeinated beverage had a slower average reaction time of 0.45917 seconds, taking longer to react. The subjects who were not exposed to any caffeine (0%) had a reaction time of 0.47293 seconds.
1. Worm Pulsation a) According to the hypothetical data depressants like alcohol have little influence on pulsations rate. Depressants slightly decreased the worms’ pulsation during the experiment. Stimulants like caffeine and ginseng had a much more significant influence on pulsation rate.
