Synthetic Investigations In Chemical Probe Development Part 1: Design And Synthesis Of Novel Triton X-405 Adenosine Conjugates; Part 2: Synthesis Of 2,8-Dihydroxychrysene, Rachel Irene Hammond
Synthetic Investigations In Chemical Probe Development Part 1: Design And Synthesis Of Novel Triton X-405 Adenosine Conjugates; Part 2: Synthesis Of 2,8-Dihydroxychrysene, Rachel Irene Hammond
Honors Theses
Although not drugs themselves, chemical probes are a necessary tool in biomedical research for the interrogation of biological systems. In the present synthetic investigation, two chemical probes were developed – a Triton X-405 adenosine conjugate (TX-405A) and 2,8-dihydroxychrysene. The designed TX-405A conjugate was generated in four steps through tosylation and amination of TX-405 such that EDC-coupling of TX-amine with 2’,3’-Isopropylidene adenosine-5’-carboxylic acid afforded TX-405A following acetonide deprotection. The development of TX-405A represents the first report of the synthesis and utilization of a detergent-linked dosimeter. The synthesis of 2,8-dihydroxychrysene provided an in-depth exploration on the unique reactivity of chrysene. The desired …
Effects Of Waterborne Benzo[A]Pyrene Embryonic Exposure On Development, Behavior, Reproduction, And Mitochondrial Bioenergetics In Zebrafish, Megha Patel
Honors Theses
Benzo[a]pyrene (BaP) is a polycyclic aromatic hydrocarbon (PAH) that is a known carcinogen leading to adverse effects in the development of both humans and animals. BaP is also continuously present in the environment leading to regular exposure via inhalation or ingestion. Because organisms’ early life stages can be more susceptible to contaminant exposure, our focus was on BaP’s adverse impacts on survival, length, weight, behavior, bioenergetic state, and fecundity following developmental exposures. To study BaP’s impacts, zebrafish (Danio rerio) were used as a model organism. BaP is a ligand for the aryl hydrocarbon receptor (AHR in humans; Ahr in …

Digoxin toxicity can present with varying manifestations. While pathognomonic symptoms such as xanthopsia (object appearing yellow) are a board favorite it is not a required finding and is in fact not seen with most patients. Rather digoxin toxicity presents with more non-specific symptoms such as GI distress (anorexia, N/V) neurological distress (lethargy, fatigue, delirium, confusion, disorientation, weakness. EKG findings are varied and include premature ventricular contractions, bradycardia, atrial tachyarrhythmias with AV block, ventricular bigeminy, junctional rhythms, various degrees of AV nodal blockade, ventricular tachycardia, and ventricular fibrillation. Although rarely seen, digoxin is one of the only causes of bidirectional ventricular …

Synthesis Of Selenotryptophan For Protein Elucidation, James P. Reiselman
[Archive] Belmont University Research Symposium (BURS)
Through complex intermolecular and intramolecular forces, proteins conformationally change to form complex 3-d geometry that carries out biochemical processes and mapping their structures is becoming a field of interest in the biological community. Techniques for modeling protein’s structure typically follow the path of X-ray crystallography, which has an intrinsic phase problem that can make reading the electron density map they produce very difficult. This can be mitigated by appending a heavy-atom containing amino acid analogue into a crystal sample of the protein being studied. A selenium containing tryptophan analogue will be synthesized to be appended into proteins as a chemical …
