Nanogels have emerged as a notably safer and more effective means for drug delivery, primarily due to their adjustable drug-loading capabilities. Hollow-core nanoparticles offer some unique properties that are desirable for drug delivery applications. Initially, silica core nanoparticles were synthesized using the Stöber process at different temperatures where Tetraethoxysilane (TEOS) undergoes hydrolysis in the presence of ethanol and then a condensation reaction to form silica nanoparticles. Scanning Electron Microscopy (SEM) and Optical Microscopy (OM) analysis revealed that the size of silica core particles varied with the synthesis temperature (300 nm at 30°C to 150 at 60°C). The core silica particles …

The opioid epidemic impacted over 12 million Americans in 2019. Although they are effective pain-relieving medications, they carry addictive and dangerous side effects. Opioids, like morphine, bind non-selectively in both central and peripheral tissues; however, dangerous side effects result from central activation. Inflamed conditions of injured tissues have a lower pH (pH=6-6.5) environment than healthy central tissue (pH=7.4). We aim to design a morphine derivative that binds selectively within inflamed tissue using computationally-based molecular extension and dissection techniques. Binding to the mu-opioid receptor (MOR) is dependent on protonation of the biochemically active amine group of morphine. Fluorination of a carbon …

Student Scholar Symposium Abstracts and Posters
Molecular extension and dissection techniques are used to design a morphine derivative that promotes selective binding in inflamed tissue due to its lower pH while avoiding dangerous activation in the brain. Morphine is used to treat pain associated with inflammation. While being effective analgesics, opioids carry the risk of central side effects, including addiction, respiratory depression, and sedation. Opioids are agonists that bind to the μ-opioid peptide receptor (MOR) within central and peripheral nerves and act via a G-protein coupled receptor pathway.
Deprotonation of the tertiary amine induces a negative charge on the nitrogen, discouraging binding at physiological pH (pH=7.4). …

Opioids such as morphine are important pain-relieving drugs but also carry a risk of harmful side effects including addiction. Morphine is active in both healthy and inflamed tissue, however, decreasing the pKa of the biochemically-active amine group can promote selective binding in the more acidic conditions of inflamed tissue and reduce harmful side effects associated with opioids. Herein, we explore the impact of fluorination on the pKa of fluoromorphine derivatives to identify which will bind selectively in inflamed tissue. Theoretical pKa values are determined at the M06-2X(SMD)/aug-cc-pVDZ level of theory to calculate the ΔGaq" …

Compounded Gabapentin For Felines: Associated Metabolic Processes And Analysis Of Potency, Johnny Altwal
Student Scholar Symposium Abstracts and Posters
Pharmaceutical compounding provides pharmacists and clinicians the opportunity to create unique drug formulations that are better suited to a specific patient’s needs. This is especially prevalent in veterinary medicine where clinicians treat a variety of maladies in a large number of species, thereby requiring unique formulations to more easily deliver drugs to animals. Several examples of compounded veterinary formulations with sub-therapeutic potencies have been published, but none examine compounded gabapentin. Gabapentin is frequently compounded into an oral suspension for veterinary use from tablets or capsules for the purpose of pain management in felines and other small animals. The project’s goals …

Structure Activity Relationship Studies Of Novel Diarylpentanoid Analogs Targeting The Androgen Receptor In Prostate Cancer Cells, Haili Coffin, Marco Bisoffi

The development of prostate cancer (PCa) relies strongly on the activation of the androgen receptor (AR) signaling pathway by its natural ligand dihydrotestosterone. Furthermore, PCa progression to metastatic disease represents oncogene addiction to AR activity. Androgen ablation therapy is thus a mainstay therapy against this disease, but the development of ligand-independent AR activation and persisting AR expression eventually leads to castration resistant PCa (CRPC). Therefore, down-regulation of AR expression in PCa cells may be an effective therapeutic modality. The diarylpentanoid ca27 has previously been shown to down-regulate AR expression by an unknown mechanism of action. The present work represents a …
