Total Synthesis Of The Marine Cytotoxic Mansouramycin And Derivatives, Aditya Dantu, Gabriella L. Madrigal, Neel Gondi, David Osazee, Ahmad Amro, Whard Alsabbagh, Shizue Mito

Research Colloquium

Purpose: Isoquinolinequinones are a group of organic compounds which are composed of an isoquinoline fused to a quinone ring. This class of molecules is known to exhibit a wide variety of biological activities, including cytotoxic and antitumor properties. Among the many families of isoquinolinequinones are the Caulibugulones and Mansouramycins, which exhibit anticancer properties and are thus desirable subjects for cancer-related research. They are obtained by isolation from marine bryozoan Caulibugula intermis and marine Streptomyces sp respectively, however these compounds are difficult to extract. Thus, organic synthesis is being explored as a method of obtaining them; this project focuses on the …

Cobenfy(Xanomeline/Trospium) Vs. Clozapine For Treatment-Resistant Schizophrenia, Harmann Singh, Akash M. Patel, Abdullah Noory, Kush C. Patel, Simran Gandhi

Rowan-Virtua Research Day

Background: Treatment-resistant schizophrenia (TRS) poses significant therapeutic challenges. Although clozapine remains the gold-standard pharmacologic treatment for TRS, its clinical utility is hampered by severe side effects and intensive monitoring requirements. KarXT (Cobenfy), a combination of xanomeline and trospium chloride, represents a novel antipsychotic approach by targeting muscarinic M1/M4 receptors instead of dopamine D2 pathways.

Hypothesis: KarXT offers comparable efficacy to clozapine with a more favorable safety and tolerability profile, making it a viable alternative for patients with TRS.

Methods: A systematic review was conducted to identify studies from 2015–2025 evaluating KarXT in schizophrenia. Sources included PubMed, ClinicalTrials.gov, FDA databases, ICER …

Hydralazine-Induced Vasculitis Resulting In Large Pleural Effusion And Progressive Renal Dysfunction, Michael A. Acevedo, Hammad Choudhry

Rowan-Virtua Research Day

Hydralazine is a vasodilator commonly used to treat high blood pressure. Even with the safety profile of Hydralazine, it is necessary to know that it may lead to Hydralazine-Induced Vasculitis. Here, we discuss how this rare side effect can present in an 80-year-old female with a past medical history of hypertension who presented to the emergency department with complaints of progressive shortness of breath on exertion and while lying supine. Further evaluation revealed a large right-sided pleural effusion with consolidation at the right lower lobe. The patient’s dyspnea worsened, and the surgical team placed a chest tube. The patient also …

Rowan-Virtua Research Day

Serotonin syndrome, a potentially life-threatening condition, can be challenging to diagnose due to its diverse etiology and varied symptomatology. Despite its severity, serotonin syndrome may present from mild to fatal, with symptoms such as autonomic instability, altered mental status, and neuromuscular excitation (e.g. muscle rigidity, hyperreflexia). Here, we present a 20-year-old male with an extensive psychiatric history who was prescribed clomipramine and developed serotonin syndrome. Few cases of serotonin syndrome have been reported to date, exacerbating the difficulty in recognizing and quickly treating such cases. Cases of serotonin syndrome should continue to be reported, in order to familiarize clinicians with …

Posttraumatic Stress Disorder (PTSD) affects 3–4% of pregnant and postpartum individuals and is associated with complications such as preterm birth, low birth weight, and postpartum depression. Pharmacologic treatment options during pregnancy are limited by concerns about fetal safety.

Methods: A literature review was conducted focusing on studies reporting maternal or neonatal outcomes following prazosin exposure in pregnancy.

Results: One observational study of 11 pregnancies found 54.5% had uneventful outcomes, with rates of preterm birth, miscarriage, and preeclampsia similar to the general population. Hypotension and limited lactation data remain concerns.

Conclusion: Early evidence suggests prazosin may be a relatively safe and …


Examining The Relationship Between Sleep Habits And Caffeine Consumption, Daniel Calaff, Rachel Pruchno May 2025

Examining The Relationship Between Sleep Habits And Caffeine Consumption, Daniel Calaff, Rachel Pruchno

Rowan-Virtua Research Day

Sleep is essential for cognitive function, mood regulation, immune defense, and metabolic health. Despite widespread caffeine use, its impact on sleep remains debated. It was initially hypothesized that higher caffeine consumption would correlate with greater sleep disturbances. This study explored the relationship between caffeine consumption and sleep habits in a general adult population using a Qualtrics-based self-report survey. Participants (n=93) reported average hours slept per night, time to fall asleep, and number of nighttime awakenings. Caffeine consumption was calculated based on reported intake and categorized into four dosage groups. Sleep outcomes were statistically compared using ANOVA, t-tests, and Pearson correlation. …

Synthesis Of Medicinally Privileged Spiro-Β-Lactams, Debasish Bandyopadhyay, Reinaldo Mendes, Subhash C. Chauhan

Research Symposium

Background: Four-membered cyclic amide, commonly known as β-lactam, has been playing a crucial role in drug discovery research since its discovery by Alexander Fleming in 1928 from Penicillium notatum. The β-lactam antibiotics are broadly effective against several bacterial infections through acylating the transpeptidase involved in cross-linking peptides to form peptidoglycan or periplasmic murein, which is a fundamental constituent of the bacterial cell wall for both the gram-positive (ten or more layers) and gram-negative (one or two layers) bacteria. Although for more than eight decades, β-lactams have been recognized as antibiotics, later, other medicinal activities of β-lactam derivatives have been …


Effects Of Dexmedetomidine As An Adjunct To General Anesthesia On Postoperative Pain And Opioid Consumption In Major Abdominal Surgery, Ahmad H. Elrefahy May 2024

Effects Of Dexmedetomidine As An Adjunct To General Anesthesia On Postoperative Pain And Opioid Consumption In Major Abdominal Surgery, Ahmad H. Elrefahy

Rowan-Virtua Research Day

This review examines the impact of dexmedetomidine, an alpha-2 adrenergic receptor agonist, on postoperative pain and opioid consumption in major abdominal surgery. Dexmedetomidine, known for its sedative, analgesic, and opioid-sparing properties, is increasingly used as an adjunct to anesthesia. Analyzing existing literature, the review found that dexmedetomidine administration alongside general anesthesia significantly improves postoperative pain management and reduces opioid consumption. Patients receiving dexmedetomidine reported decreased postoperative pain ratings and required fewer opioids during the recovery phase. Additionally, intraoperative dexmedetomidine use correlated with reduced postoperative pain severity and increased patient satisfaction compared to control groups. However, potential side effects such as …


Mechanistic Investigation Of C—C Bond Activation Of Phosphaalkynes With Pt(0) Complexes, Roberto M. Escobar, Abdurrahman C. Ateşin, Christian Müller, William D. Jones, Tülay Ateşin Mar 2024

Mechanistic Investigation Of C—C Bond Activation Of Phosphaalkynes With Pt(0) Complexes, Roberto M. Escobar, Abdurrahman C. Ateşin, Christian Müller, William D. Jones, Tülay Ateşin

Research Symposium

Carbon–carbon (C–C) bond activation has gained increased attention as a direct method for the synthesis of pharmaceuticals. Due to the thermodynamic stability and kinetic inaccessibility of the C–C bonds, however, activation of C–C bonds by homogeneous transition-metal catalysts under mild homogeneous conditions is still a challenge. Most of the systems in which the activation occurs either have aromatization or relief of ring strain as the primary driving force. The activation of unstrained C–C bonds of phosphaalkynes does not have this advantage. This study employs Density Functional Theory (DFT) calculations to elucidate Pt(0)-mediated C–CP bond activation mechanisms in phosphaalkynes. Investigating the …

Rowan-Virtua Research Day

Xylazine, according to the National Institutes of Health (NIH), is a non-opioid tranquilizer used in veterinary medicine. Although this drug has not been approved for human use, it can be linked to an increase in opioid overdose deaths due to its role as an adulterant in drugs like fentanyl.

Xylazine was detected in drugs involved in 41% of all opioid-involved unintentional deaths and in 44% of all unintentional overdose deaths with fentanyl involved in the year of 2021 in Philadelphia.


Triazole Compounds – Potentials In The Treatment Of Cystic Fibrosis, Maggie Taylor Mar 2023

Triazole Compounds – Potentials In The Treatment Of Cystic Fibrosis, Maggie Taylor

Undergraduate Research Conference

Cystic Fibrosis (CF) is a genetic disease that affects the respiratory and digestive system and is most common among Caucasians of Northern European origin. CF is caused by mutations in a membrane protein CFTR (Cystic Fibrosis Transmembrane-conductance Regulator). This mutation impairs the membrane protein’s chloride ion channel function. One of the most common CFTR mutations is the DF508 mutation that affects over 70% of CF cases. Our research has shown that the DF508-CFTR mutation can be partially reversed by physical and chemical means [Heda & Marino, BBRC, 271:659-664, 2000]. In cell lines expressing DF508-CFTR, synthetic anion carriers have shown to …

Designing And Synthesizing A Warhead-Fragment Inhibitory Ligand For Ivyp1 Through Fragment-Based Drug Discovery, Samuel Moore

Symposium of Student Scholars

Fragment-based drug discovery (FBDD) is a powerful tool for developing anticancer and antimicrobial agents. Within this, magnetic resonance spectroscopy (NMR) provides a comprehensive qualitative and quantitative approach to screening and validating weak and robust binders with targeted proteins, making NMR among the most attractive strategies in FBDD. Inhibitor of vertebrate lysozyme (Ivyp1) of P. aeruginosa serves as an excellent target because of its active cellular location and implications in clinical prognosis for cystic fibrosis and immunocompromised patients. This study uses current NMR and biophysical techniques to develop a covalent, fragment-linked warhead inhibitor for Ivyp1 through synthetic methods, warhead linking, and …


Treating Trichotillomania With Olanzapine, Christopher Lee May 2022

Treating Trichotillomania With Olanzapine, Christopher Lee

Rowan-Virtua Research Day

Trichotillomania (TTM) is characterized by repetitive pulling of one’s hair leading to hair loss and problems in social, occupational, or other important areas of functioning. Often individuals with TTM try to decrease or stop hair pulling, however are often unsuccessful without treatment. Community prevalence studies suggest that TTM is a common disorder with point prevalence estimate of 0.5% to 2.0% and with significant psychological comorbidity. Of note, people with TTM are often embarrassed about their condition, so epidemiology data may be underestimated compared to the true prevalence of this condition. The female to male ratio for this condition is 4:1. …


Synthesis Of 5-Membered Ring Heterocycles For Alzheimer’S Disease, Daniel Fajardo Mar 2021

Synthesis Of 5-Membered Ring Heterocycles For Alzheimer’S Disease, Daniel Fajardo

Honors Scholars & Undergraduate Research Poster Symposium Programs

The progression of Alzheimer’s disease (AD) is correlated to the degenerative activation of muscarinic acetylcholine receptors (mAChR) located in the brain. They are a family of five G-protein coupled receptors, (M1-M5), linked to functions within the central and peripheral nervous system.1 More specifically, activation of M1 with positive allosteric modulators (PAM), have shown to bind to the allosteric pocket and slow the degenerative process of AD with minimal intrinsic effects.2 Structural motifs of potent PAM activity and weak agonism proposed a synthesis of an isooxazoline compound, incorporating a 1,3-dipolar cycloaddition. The core motif of the proposed isooxazoline structure has been …

Stable Nanopalladium Hydride In Water For Sustainable And Selective Reductions, Jesse Klus, Sachin Handa Oct 2019

Stable Nanopalladium Hydride In Water For Sustainable And Selective Reductions, Jesse Klus, Sachin Handa

Posters-at-the-Capitol

The synthesis of air-stable ligand-free nanopalladium hydride (PdNHx) in water was achieved and applied to various organic transformations, including (1) reduction of heteroaromatics such as (iso)quinolines, phenanthrolines, benzotriazole, and naphthyridines, (2) regio- and chemoselective reduction of nitroarenes, (3) alkyne reductions, (4) chemoselective dehalogenation, and (5) base-free detriflation. Both the synthesis of PdNHx and the reductions were carried out under mild conditions in a micellar medium using our designer surfactant PS-750-M, which eliminates the need for toxic organic solvents and extremely high hydrogen pressure and temperature. Notably, PS-750-M is also a replacement of hazardous polar-aprotic solvents. This newer approach for selective …
