Synthesis Of Cyclopropyl Analogs Of Acetylcholine, Douglas Armstrong, Zachary Emptage Apr 2019

Synthesis Of Cyclopropyl Analogs Of Acetylcholine, Douglas Armstrong, Zachary Emptage

Scholar Week 2016 - present

The Ph.D. research by Douglas Armstrong was highly successful for the synthesis of the trans cyclopropyl analog of acetylcholine, but only marginally successful for the cis isomer. In recent years he has developed novel ideas as to how the synthesis of the cis isomer may be improved upon, in ways using more current methods. He has done experiments using some of those methods, and the results, although preliminary, look good.


Synthesis Of A Sulfur Variant For Treatment Of Trypanosomiasis, Carlos Vera-Esquivel Mar 2019

Synthesis Of A Sulfur Variant For Treatment Of Trypanosomiasis, Carlos Vera-Esquivel

Student Research and Creative Activity Fair

Previous work in our lab has found diphenyl ether benzylamines showed a successful response with a micromolar concentration of our lead compound to treat the deadly Trypanosamiosis rhodesience. Furthermore, mammalian cell lines saw promising resistance towards damages. The goal of this study was to synthesize a diphenyl thio benzylamine variant. This variant was more active toward T. b. rhodesience but showed more toxicity to both rat 10 (IC50 mM) and human cell lines (HFF, HC-04, U-2 OS, and HEK293). The selectivity index (ratio of toxicity to activity in the same concentration units (SI)) varied from 55 ...


An In Vitro Study On Skin Protection Across The Uv Spectra, Cheyenne Boone Nov 2018

An In Vitro Study On Skin Protection Across The Uv Spectra, Cheyenne Boone

Posters-at-the-Capitol

Skin cancer is the number one cancer in the United States. Lack of awareness of how harmful UV radiation is could be the cause of the over two million cases reported since 2012. It appears that there is not a lot information on the active ingredients used in sunscreens. Some of the compounds have been linked to birth defects, hormone disruptions, and the bleaching of coral reefs. Samples of commonly used sunscreens (both sprays and creams), cosmetic foundation, essential oils, lotions, and three pure organic actives were tested at specific concentrations and ran through a UV spectrometer. The results have ...


New Reactions Of Strained Allyl Silacycles, Elizabeth Cummins May 2018

New Reactions Of Strained Allyl Silacycles, Elizabeth Cummins

Graduate Student Symposium

Ring-strained allylsilanes exhibit both electrophilic and nucleophilic characteristics, allowing for simultaneous activation and allylation of carbonyl compounds. Results are presented describing an optimized synthesis of certain allylsilacyclobutanes and their use in several selective carbon-carbon bond forming reactions.


Tunable Copper Complexes For Sustainable Photocatalysis, David Kline Nov 2017

Tunable Copper Complexes For Sustainable Photocatalysis, David Kline

Posters-at-the-Capitol

Photoredox catalysis has direct applications in sustainable chemistry and thus an immense impact on our environment. With the ability to harness energy directly from the sun to catalyze useful chemical reactions, photocatalysts can help to eliminate the need for harsh reaction conditions and reduce generation of hazardous chemical waste. Photocatalysts based on Earth-abundant metals such as copper have recently emerged as sustainable alternatives to rare-earth metals including iridium and ruthenium, which are no longer required for many photocatalyzed chemical transformations.


Spectrofluorometric Analysis Of Bisphenol-A In Drinking Water Bottles, Jeff Brochetti Apr 2017

Spectrofluorometric Analysis of Bisphenol-A in Drinking Water Bottles

Bisphenol-A (BPA) is of environmental concern due to its ability to act as an endocrine disruptor in humans and many other animals. In the food industry, BPA is widely used in the production of plastic bottles and plastic liners in aluminum cans. Over time, trace amounts of BPA can leach from the container and into the contents inside. A new method of testing for trace amount of BPA involved the formation of an inclusion complex with ß-Cyclodextrin. With the formation of the inclusion complex, it becomes much easier to analyze low concentrations ...
