Pyrrolizidine alkaloids (PAs) are a class of toxic compounds found in the composition of more than 6000 plants. People can be exposed to PAs by consuming phytotherapeutic products, food from crops contaminated with seeds of some species with high content of PAs, and/ or contaminated animal products like bee products. For this reason we developed and validated a method for quantitative determination of PAs, from the most frequently contaminated food sources, honey and flour. Colorimetric Ehrlich reagent method was used with standard addition (1mg/kg senecionine). The extraction solvent was methanol 50% acidified with citric acid to pH 2-3, as ...

A V-To-F Substitution In Sk2 Channels Causes Ca2+ Hypersensitivity And Improves Locomotion In A C. Elegans Als Model, Young-Woo Nam, Sabia N. Baskoylu, Dimitris Gazgalis, Razan Orfali, Meng Cui, Anne C. Hart, Miao Zhang

Pharmacy Faculty Articles and Research

Small-conductance Ca2+-activated K+ (SK) channels mediate medium afterhyperpolarization in the neurons and play a key role in the regulation of neuronal excitability. SK channels are potential drug targets for ataxia and Amyotrophic Lateral Sclerosis (ALS). SK channels are activated exclusively by the Ca2+-bound calmodulin. Previously, we identified an intrinsically disordered fragment that is essential for the mechanical coupling between Ca2+/calmodulin binding and channel opening. Here, we report that substitution of a valine to phenylalanine (V407F) in the intrinsically disordered fragment caused a ~6 fold increase in the Ca2+ sensitivity of SK2-a channels. This substitution resulted in a ...

Progress Toward The Development Of A "Catch/Release" Strategy For Isolating Salvinorin A, From Plant Materails Including Microwave Promotion, Douglas Armstrong, Logan Smith 2017 Olivet Nazarene University

Progress Toward The Development Of A "Catch/Release" Strategy For Isolating Salvinorin A, From Plant Materails Including Microwave Promotion, Douglas Armstrong, Logan Smith

Faculty Scholarship – Chemistry

We are investigating using the Diels-Alder and retro-Diels-Alder reactions as a potential “catch/release” strategy for isolating Salvinorin A from plant samples (Salvia divinorum), hopefully to improve the current method, which is very long and laborious. Salvinorin A has analgesic activity by activating the kappa opioid receptor, not the mu receptor, and thus it has potential for being developed into a non-addicting analgesic.


Applied Drug Development And Combinatorial Strategies For Antimicrobial Treatment, Steven K. Lai Hing 2017 Texas A & M University - College Station

Applied Drug Development And Combinatorial Strategies For Antimicrobial Treatment, Steven K. Lai Hing

Andrews Research Conference

Streptococcus mutans JH1140 is a strain of bacteria which produces a lantibiotic product, named mutacin 1140. Mutacin 1140 has been shown to be effective at inhibiting Gram-positive bacterial infections caused by Staphylococcus aureus and Streptococcus pneumoniae. Mutacin 1140 is a ribosomally synthesized peptide antibiotic that undergoes extensive posttranslational modifications (PTM). We have found that Mutacin 1140 and an aminoglycoside, Kanamycin, when combined together, act synergistically against Staphylococcus aureus. This was determined by performing serial kill curve dilution overlays on solid media, followed up with kill curve by microdilution plate, and most recently confirmed with kill curve CFU count plates on ...

The Effects Of Apigenin On Cell Proliferation And Apoptosis In Glioblastoma Multiforme, Trevor Stump, Brittany Santee, Lauren Williams, Chelsae Heinze, Rachel Kunze, Samson Amos, Denise S. Simpson

Denise (Simpson) Jean-Louis, Ph.D.

Glioblastoma multiforme (GBM) is a WHO grade IV brain tumor. These tumors are highly proliferative, infiltrative, necrotic, angiogenic, and resistant to apoptosis. One major characteristic of GBM is the overexpression of epidermal growth factor receptor (EGFR), which leads to cell growth and proliferation when activated. GBM is very difficult to treat due to its location, heterogeneity, and invasiveness; an effective treatment is therefore needed. The use of flavonoids, which are natural compounds found in many fruits and vegetables, has been studied in the treatment of many different tumor types. Apigenin is a specific flavonoid that has previously been shown to ...
