Synthesis Of Resveratrol Esters And Aliphatic Acids., Stanley Mofor Jing

Electronic Theses and Dissertations

Resveratrol (RV) is a naturally occurring phytoalexin of the stilbenoid family produced by some plant species, and present in grape skin, peanuts, and red wine. It has been found to exhibit anti-cancer, anti-inflammatory, anti-viral, anti-aging, cardio protective, and anti-oxidant properties. Bioavailability is a huge setback that limits the potentials of RV. As a result, efforts have been made to design and synthesize RV esters and aliphatic acids in an attempt to increase its bioavailability, solubility in water, and possibly improving its biological activities. Resveratrol esters, 3,5,4'-triacetyloxystilbene (2) and Methyl 1,1',1''- (3,4',5-stilbenyl)-1,6-hexanedioate (3) have been synthesized. Compound 3 is a new …

Synthesis Of Resveratrol Ester Derivatives Using Selective Enzymatic Hydrolysis., Marian Osei-Mensah

Electronic Theses and Dissertations

Resveratrol, a naturally derived stilbene, is an interesting compound mostly talked about recently because for its anti-cancer properties. Unfortunately it has some shortcomings due to its low bioavailability and low solubility in water. For this reason, my research is to overcome resveratrol's drawbacks by improving its bioavailability and hydrophilicity. My research is focused on syntheses of novel derivatives of resveratrol such as 3, 5-di-O-isobutyroyl resveratrol and 3, 5-di-O-hexanoyl resveratrol using lipase catalyzed hydrolysis. Therefore, the tri-acylated resveratrols 3, 5, 4'-tri-O-isobutyroyl resveratrol and 3, 5,4'-tri-O-hexanoyl resveratrol were first synthesized.

3,5,4'-tri-O-isobutyroyl resveratrol and 3,5,4'-tri-O-hexanoyl resveratrol were then hydrolyzed using lipase (C. …

The Effects Of Stereotype Disconfirming Information And Self-Disclosure On Stereotype Endorsement, Prejudice, And Social Tolerance Of Schizophrenia And Major Depressive Disorder., Nicole Leigh Meyer 1983-

Electronic Theses and Dissertations

The current study examined how Disclosure, Stereotype Disconfirming Information, and Stereotype Disconfirming Information and Disclosure Combined) influences an individual's stigma (stereotype endorsement, emotional reactions, and discrimination) against individuals with Schizophrenia and Depression. The results of this experiment suggest that both Stereotype Disconfirming Information and Disclosure are successful in reducing stereotypes, emotional reactions, and social distance in the context of an interpersonal encounter. Self-disclosure, however, is stronger in increasing Pity and decreasing the desire for Social Distance than Stereotype Disconfirming Information. The combination of Stereotype Disconfirming Information and Disclosure provided the strongest stigma reduction, suggesting that Disclosure can benefit from the …
