Smart Spectrophotometric Approaches For Estimation Of Difluprednate In Existence Of Its Synthetic Precursor And Alkaline Degradation Product; Comparative Statistical Studies And Analytical Ecological Appraisal, Heidi R. Abd El-Hadi, Basma M. Eltanany, Hala E. Zaazaa, Maya S. Eissa

Bulletin of Faculty of Pharmacy Cairo University

Scientists are currently attempting to lessen the harmful effects that chemicals and solvents have on the environment. The current work suggests four sensitive and sustainable spectrophotometric techniques for quantifying difluprednate (DIF) in presence of hydrocortisone acetate, which is a synthetic precursor of DIF, and in the presence of DIF alkaline degradation product. These methods are dual wavelength, fourier self-deconvolution, first derivative, and double divisor derivative ratio. The linearity range for all methods was 15.00-40.00 µg/mL. There is no statistically significant difference between established and reported methods, and the suggested strategies are more environmentally friendly than the reported one.

Near-Neutral Balanced Selection Theory (Nnbst): Implication On The Molecular Evolution Of Sars-Cov-2 And Zika Virus, Nicholas J. Paradis Mar 2024

Near-Neutral Balanced Selection Theory (Nnbst): Implication On The Molecular Evolution Of Sars-Cov-2 And Zika Virus, Nicholas J. Paradis

Graduate Student and Postdoctoral Fellow Symposium

Virus pandemics have significantly impacted human welfare and development. Understanding the true molecular evolution of viruses is critical for preventing future pandemics and developing the next-generation drugs and vaccines. Unfortunately, viruses exhibiting constant genomic substitution rates (GSRs) despite increasing vaccinations and human infections (SARS-CoV-2) and viruses under seemingly extreme conservation (ZIKV) paints a confusing picture of viral evolution, and the main evolutionary theories (Selectionist Theory, Kimura’s Neutral Theory) cannot explain their molecular evolution. Here, we developed a first-principle model, c/u, to characterize reproductive fitness changes in viruses based on variations in the nucleotide/codon mutation rate (c) with respect to the …

Methionyl-Trna Synthetase Synthetic And Proofreading Activities Are Determinants Of Antibiotic Persistence, Whitney N. Wood, Miguel Angel Rubio, Lorenzo Eugenio Leiva, Gregory J. Phillips, Michael Ibba

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Bacterial antibiotic persistence is a phenomenon where bacteria are exposed to an antibiotic and the majority of the population dies while a small subset enters a low metabolic, persistent, state and are able to survive. Once the antibiotic is removed the persistent population can resuscitate and continue growing. Several different molecular mechanisms and pathways have been implicated in this phenomenon. A common mechanism that may underly bacterial antibiotic persistence is perturbations in protein synthesis. To investigate this mechanism, we characterized four distinct metG mutants for their ability to increase antibiotic persistence. Two metG mutants encode changes near the catalytic site …

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 …

Pharmacy Faculty Articles and Research

Background

Biologic TNF-α inhibitors (bTNFIs) can block cerebral TNF-α in Alzheimer’s disease (AD) if these macromolecules can cross the blood–brain barrier (BBB). Thus, a model bTNFI, the extracellular domain of type II TNF-α receptor (TNFR), which can bind to and sequester TNF-α, was fused with a mouse transferrin receptor antibody (TfRMAb) to enable brain delivery via BBB TfR-mediated transcytosis. Previously, we found TfRMAb-TNFR to be protective in a mouse model of amyloidosis (APP/PS1) and tauopathy (PS19), and herein we investigated its effects in mice that combine both amyloidosis and tauopathy (3xTg-AD).

Methods

Eight-month-old female 3xTg-AD mice were injected intraperitoneally with …
