In 2017 Welch summer research program Advisors: Drs. Paul Pyenta and Hyunshun Shin Drs. Shin and Pyenta worked jointly with all 4 students: |
Advisors: Drs. Paul Pyenta and Hyunshun Shin Haley Shepard tested synthesized HDAC inhibitors for use as anti-cancer agents modeled after SAHA in MCF-7 and MDA-MB-231 breast cancer cell lines. |
Advisors: Drs. Paul Pyenta and Hyunshun Shin Bethany Everett worked on creating a HDACi that interferes with the HAT/HDAC enzymatic activity in cancer cells. |
Advisors: Drs. Paul Pyenta and Hyunshun Shin Alisa Rasley tested synthesized HDAC inhibitors for use as anti-cancer agents modeled after SAHA in MCF-7 and MDA-MB-231 breast cancer cell lines. |
Advisors: Drs. Paul Pyenta and Hyunshun Shin Ananda Lewis designed and synthesized HDACs Inhibitors as Anticancer Agents |
Megan Butler 2017 Summer Research advisor: Dr. Donnay Megan synthesized a new chromium polypyridyl complex and made progress towards an analogue of the DPPZ ligand that might allow metal complexes to bind better to DNA for possible use in photodynamic therapy. |
In 2016 Welch summer research program Advisors: Drs. Paul Pyenta and Hyunshun Shin Drs. Paul Pyenta and Hyunshun Shin worked jointly with all 5 students: Genna Hart and Ananda Lewis worked on discovery of new bioactive compounds from extracts of West Texas Plants. Mukundwa Gael, George Gutierrez and Shantel Thomas synthesized new histone deacetylase inhibitors, followed by evaluating breast cancer cell viability with them in breast cancer MCF-7 and MDA-MB-231 cell lines for potential anticancer agents. |

Parker’s research project is to develop new synthetic methods using FirstMate Synthesizer toward Histone Deacetylase Inhibitors. Parker |
"Sophie synthesized a new bridging ligand." |
"Stephen made progress towards new intercalating ligands." |
Damon’s research projects are to develop the purication methods of organic compounds, and to synthesize novel hydroxamic acid derivatives for potential anticancer drugs. |
Synthesis of New Inhibitors of Histone deacetylases |
Staci Palacios synthesized beta-lactamase inhibitors for potential antibiotics. |
![]() 2012 & 2013 summer advisor: Dr. Donnay Christi modified a ligand to increase the emission intensity of the resulting chromium complex. |
Josh worked on making new ligands and a bridging chromium compound. |
The project is a continuation of the project begun by Heather Whitehead, designing and synthesizing other inhibitors of ornithine decarboxylase. |
Toyosi worked to find a way to separate various chromium compounds using the HPLC. She also developed procedures to determine how well these complexes bind to DNA. |

This project is a joint project between Dr. Donnay and Dr. Shin. It involves the design and synthesis of small molecules that target a wide range of Gram-negative bacteria. |
Heather worked to design and synthesize an inhibitor of ornithine decarboxylase. |
Design optimization of GFP-encoding vector for inducible expression in bacillus thuringensis; compatible promoters and regulatory sequences. |
two projects: 1. Design of a GFP-encoding vector compatible for transfection into Bacillus Thuringiensis. 2. Investigation of antibody IgG structure in solution using FRET analysis. |
Tim worked with Dr. Donnay to synthesize a ligand which could be used to make self-assembled monolayers. |
Design of a GFP-encoding vector compatible for transfection into Bacillus Thuringiensis. |
Liquid chromatography analysis of fluorescently tagged IgE. |
Dr. Pyenta and I are working on fluorescently tagging a bacterium by transfecting GFP plasmids into the bacterium's own genetic code through electroporation. The bacterium, Bacillus Thuringiensis, is a bioinsecticide that that produces a delta-endotoxin during sporulation which is toxic to some insects. If successful, we will be able to track the bacterium through the intestinal tract of various insects and test its effectiveness as a bioinsecticide. |
I am doing research in fluorescence resonance energy transfer (FRET) of monoclonal antibodies. To determine size and conformation of these antibodies, namely IgG, would be beneficial both to the pharmaceutical and academia world. Most of this research thus far has been trying to develop improved fluorescencent probes through conjugation of previously untested pairs. Hopefully, the new probes will lead to a further in-depth look into the structure and functionalities of IgG. |
