Progress Toward Phidianidine Analogues Containing A 1,2,3-Triazole Ring, David Laws Iii, Dillon King, Bryan H. Wakefield

Journal of the South Carolina Academy of Science

Phidianidines are a class of compound that has been extracted from the sea mollusk Phidianis militaris. These compounds have been shown to exhibit a variety of useful properties such as antihistamine effects, anti-cancer activity, agonism of the µ-opioid receptor and neuroprotection. The biological activities are thought to be caused by the 1,2,4- oxadiazole ring found within the molecule. The goal of this project is to synthesize analogues of phidianidine that contain a 1,2,3-triazole instead of the 1,2,4 oxadiazole ring using a method that will allow for other regions of the molecule to be changed ...


Synthesis Of A Small Molecule Nitrosocysteine Inhibitor To Reduce The Activity Of Caspase-1, Catherine A. Shamblen, Caitlin E. Karver Jul 2016

Synthesis Of A Small Molecule Nitrosocysteine Inhibitor To Reduce The Activity Of Caspase-1, Catherine A. Shamblen, Caitlin E. Karver

DePaul Discoveries

Caspase-1 is an enzyme that is overactive in autoimmune and autoinflammatory diseases cleaving pro-interleukin-1β to the cytokine interleukin-1β (IL-1β), which leads to inflammatory symptoms. The inhibition of caspase-1 will cause a decrease in the concentration of interleukin-1β (IL-1β), resulting in the reduction of inflammatory symptoms. Recent research has revealed that the appending of a nitric oxide (NO) or nitroxyl (HNO) donating group to non-steroidal anti-inflammatory drugs (NSAIDs) reduced, or avoided, the side effects caused by currently available treatments. A small molecule based on a known caspase-1 inhibitor with a nitrosocysteine appended on was synthesized to look at the effect of ...


The Spontaneous Formation Of Selenium Nanoparticles On Gallic Acid Assemblies And Their Antioxidant Properties, Stacey Barnaby Fcrh '11, Nazmul Sarker Fcrh '13, Aaron Dowdell Fcrh '12, Ipsita Bannerjee Dec 2013

The Spontaneous Formation Of Selenium Nanoparticles On Gallic Acid Assemblies And Their Antioxidant Properties, Stacey Barnaby Fcrh '11, Nazmul Sarker Fcrh '13, Aaron Dowdell Fcrh '12, Ipsita Bannerjee

Gallic acid (GA) is a naturally occurring plant phenol known for its anti-inflammatory and antioxidant properties. In this work, we probed the molecular self-assembly of GA for the development of GA based nanocomposites for potential device fabrications and enhanced antioxidant applications. We found that the formation of GA nanostructures was pH dependent. Further, we examined the interactions of selenite with GA and subsequently examined the biomimetic formation of selenium (Se) nanoparticles. We found that in the presence of selenite, the yield of nanofibers was significantly higher, and selenium nanoparticle coated nanofibers were formed. The ability of the nanocomposites to scavenge ...


Preparation Of An Electrophilic 3-Methylindole Derivative: Difficulties In Forming A Stable, Suitable Material For The Preparation Of Tryptophan, Jason Boggs, Mariah Mcmasters, Robert W. Curley Jr., Michael J. Panigot Jan 2000

Preparation Of An Electrophilic 3-Methylindole Derivative: Difficulties In Forming A Stable, Suitable Material For The Preparation Of Tryptophan, Jason Boggs, Mariah Mcmasters, Robert W. Curley Jr., Michael J. Panigot

Journal of the Arkansas Academy of Science

In an attempt to prepare stereoselectively beta-deuterated tryptophan, N-protected indole-3-methanol compounds were prepared with model studies being done on undeuterated material. Conversion of these compounds to electrophilic species proved exceptionally difficult and resulted in very low yields or recovered starting material only. A summary of the current results utilizing N-tosyl indole-3-methanol will be presented as well as efforts using N-Boc indole-3-methanol.
