The Mechanism Of Cirp In Inhibition Of Keratinocytes Growth Arrest And Apoptosis Following Low Dose Uvb Radiation, Yi Liao, Jianguo Feng, Yi Zhang, Liling Tang, Shiyong Wu

United States Food and Drug Administration: Publications

UV induces CIRP expression and subsequent Stat3 activation, but the biological function and mechanism of CIRP and Stat3 in mediating UVB-induced skin carcinogenesis have not been fully elucidated. In this study, we demonstrate that CIRP is elevated in all tested melanoma and non-melanoma skin cancer cell lines; and the expression of CIRP is upregulated in keratinocytes after being irradiated with relatively low dose (<5 mJ/cm²), but not high dose (50 mJ/cm²), UVB acutely and chronically. The increased expression of CIRP, either induced by UVB or through overexpression, leads to resistance of keratinocytes to UVB-induced growth arrest and …

Monitoring Harm Perceptions Of Smokeless Tobacco Products Among U.S. Adults: Health Information National Trends Survey 2012, 2014, 2015, Shari P. Feirman, Elisabeth A. Donaldson, Mark Parascandola, Kimberly Snyder, Cindy Tworek

United States Food and Drug Administration: Publications

Introduction: Changes to the U.S. smokeless tobacco landscape in recent years include a change to health warnings on packages, the implementation of bans in some stadiums, and the launch of a federal youth pre- vention campaign. It is unclear whether such changes have impacted consumer beliefs about smokeless tobacco. This study examines relative harm perceptions of smokeless tobacco compared to cigarettes among adults and assesses changes in smokeless tobacco harm perceptions over time.

Methods: We analyzed data from three cycles (2012, 2014, 2015) of the Health Information National Trends Survey (HINTS). Using 2015 data, we assessed bivariate associations between smokeless …

A Diversity-Oriented Synthesis Approach To Functionalized Azaheterocycles Using Cyclic Alpha-Halo Eneformamides, Spencer A. Langevin

All Master's Theses

Functionalized piperidines, azepanes, azamacrocycles, morpholines, and thiomorpholines are common structural motifs found in a wide range of pharmaceuticals such as carmegliptine, levofloxacin, thioridazine, claviciptic acid, and azithomycin. As a result, there is a strong desire to construct highly functionalized nitrogen-bearing ring scaffolds in order to construct a wide range of drug possibilities. There are several non-modular and step-uneconomical synthetic methods used in the construction of these aforementioned motifs such as ring closing metathesis, ring expansions, and intramolecular reductive amination. In this research, we present a step-economical, cost-effective, scalable, and diversity-oriented synthesis approach to highly functionalized N-heterocycles through the intermediacy of …

Comparison Of Outcomes Following A Switch From A Brand To An Authorized Vs. Independent Generic Drug, Richard Hansen, Jingjing Qian, Richard L. Berg, James G. Linneman, Enrique Seoane-Vazquez, Sarah Dutcher, Saeid Raofi, C. David Page, Peggy L. Peissig

Pharmacy Faculty Articles and Research

Authorized generics are identical in formulation to brand drugs, manufactured by the brand company but marketed as a generic. Generics, marketed by generic manufacturers, are required to demonstrate pharmaceutical and bioequivalence to the brand drug, but repetition of clinical trials is not required. This retrospective cohort study compared outcomes for generics and authorized generics, which serves as a generic vs. brand proxy that minimizes bias against generics. For the seven drugs studied between 1999-2014, 5,234 unique patients were on brand drug prior to generic entry and 4,900 (93.6%) switched to a generic. During the 12-months following the brand-to-generic switch, patients …

Two liver inserts, each containing 19 synthetic lesions with varying diameter (6–40 mm), shape, contrast (10–65 HU), and both homogenous and mixed-density were designed to have background and lesion CT values corresponding to arterial and portal-venous phase imaging, respectively. The two phantoms were scanned using two commercial CT scanners (GE 750 HD and Siemens Biograph mCT) across a set of imaging protocols (four slice thicknesses, …

Design, Synthesis, And Evaluation Of Dasatinib-Amino Acid And Dasatinib-Fatty Acid Conjugates As Protein Tyrosine Kinase Inhibitors, Rakesh Tiwari, Alex Brown, Neda Sadeghiani, Amir Nasrolahi Shirazi, Jared Bolton, Amanda Tse, Gennady M. Verkhivker, Keykavous Parang, Gongqin Sun

Pharmacy Faculty Articles and Research

Derivatives of dasatinib were synthesized via esterification with 25 carboxylic acids including amino acids and fatty acids by extending the inhibitor to interact with more diverse sites and to improve specificity. Dasatinib-L-arginine derivative (Das-R, 7) was the most potent of the inhibitors tested with IC50 values of 4.4 nM, <0.25 nM, and <0.45 nM against Csk, Src, and Abl kinases, respectively. The highest selectivity ratio obtained in our study, 91.4 Csk/Src belonged to compound 18 (Das-C10) with an IC50 of 3.2 μM for Csk compared to 35 nM for Src. Furthermore, many compounds displayed increased selectivity toward Src, as compared with Abl. Compounds 15 (Das-E) and 13 (Das-C) demonstrated the largest gains (10.2 and 10.3 Abl/Src IC50 ratios). Das-R (IC50 = 2.06 μM) was significantly more potent than Das (IC50 = 26.3 μM) against Panc-1 cells while they both showed an IC50 < 51.2 pM against BV-173 and K562 cells. Molecular modeling and binding free energy simulations revealed a good agreement with the experimental results and rationalized differences in selectivity of the studied compounds. Integration of experimental and computational approaches in the design and biochemical screening of dasatinib derivatives facilitated rational engineering and diversification of dasatinib scaffold, providing useful insights into mechanisms of kinase selectivity.

A Murine Model Of Inflammation-Induced Cerebral Microbleeds, Rachita K. Sumbria, Mher Mahoney Grigoryan, Vitaly Vasilevko, Tatiana B. Krasieva, Miriam Scadeng, Alexandra K. Dvornikova, Annlia Paganini-Hill, Ronald Kim, David H. Cribbs, Mark J. Fisher

Pharmacy Faculty Articles and Research

Background: Cerebral microhemorrhages (CMH) are tiny deposits of blood degradation products in the brain and are pathological substrates of cerebral microbleeds. The existing CMH animal models are β-amyloid-, hypoxic brain injury-, or hypertension-induced. Recent evidence shows that CMH develop independently of hypoxic brain injury, hypertension, or amyloid deposition and CMH are associated with normal aging, sepsis, and neurodegenerative conditions. One common factor among the above pathologies is inflammation, and recent clinical studies show a link between systemic inflammation and CMH. Hence, we hypothesize that inflammation induces CMH development and thus, lipopolysaccharide (LPS)-induced CMH may be an appropriate model to …

Pharmacy Faculty Articles and Research

A series of cyclic peptides containing a number of tryptophan (W) and glutamic acid (E) residues were synthesized and evaluated as pH-sensitive agents for targeting of acidic tissue and pH-dependent cytoplasmic delivery of molecules. Biophysical studies revealed the molecular mechanism of peptides action and localization within the lipid bilayer of the membrane at high and low pHs. The symmetric, c[(WE)4WC], and asymmetric, c[E4W5C], cyclic peptides translocated amanitin, a polar cargo molecule of similar size, across the lipid bilayer and induced cell death in a pH- and concentration-dependent manner. Fluorescently-labelled peptides were evaluated for targeting of acidic 4T1 mammary tumors in …

Antibiotic Drug Discovery With An Eye Towards Overcoming Drug Resistance, Daniel Towner Hoagland

Theses and Dissertations (ETD)

As a species, humans have become ever reliant on the use of antibiotics to facilitate our everyday lives. The widespread emergence of resistance to currently used antibiotics is commonly attributed to an over use in our society. Such resistance, coupled with a lack of innovation and production of novel antibiotic drugs, threatens to return humanity to an era similar to one before the discovery of the first antibiotics. The need to find new agents to be used in this fight is paramount, as well as learning from our recent failures to produce such compounds. This document will highlight my efforts …

Bacterial Endotoxin Detection In Hyaluronic Acid-Based Medical Devices, Larissa F. Baeva, Srilekha Sarkar Das, Victoria M. Hitchins

United States Food and Drug Administration: Publications

A simple and rapid method has been developed for testing bacterial endotoxin in hyaluronic acid (HA)-based medical devices. High-molecular-weight HA (HMW HA) in solution or HA-based medical devices was digested by the enzyme hyaluronidase to reduce solution viscosity by truncating the long chains of HA and to test for bacterial endotoxin. The bacterial endotoxin level was detected and measured by kinetic chromogenic Limulus Amebocyte Lysate (LAL) assay. The method was applied to two different ophthalmic viscosurgical devices (OVDs) and one dermal filler, and may easily be adapted to use with up to 3% HA solutions and other HA-based medical devices.

Application Of Ichip To Grow “Uncultivable” Microorganisms And Its Impact On Antibiotic Discovery, Rinzhin T. Sherpa, Caretta J. Reese, Hamidreza Montazeri Aliabadi

Pharmacy Faculty Articles and Research

Purpose. Antibiotics have revolutionized modern medicine, allowing significant progress in healthcare and improvement in life expectancy. Development of antibiotic resistance by pathogenic bacteria is a natural phenomenon; however, the rate of antibiotic resistance emergence is increasing at an alarming rate, due to indiscriminate use of antibiotics in healthcare, agriculture and even everyday products. Traditionally, antibiotic discovery has been conducted by screening extracts of microorganisms for antimicrobial activity. However, this conventional source has been over-used to such an extent that it poses the risk of “running out” of new antibiotics. Aiming to increase access to a greater diversity of microorganisms, …

Fluorescein Dye For Exploring Anti-Cancer Drug Dissolution Kinetics, Connor Davis, Tonglei Li, Wei Gao

The Summer Undergraduate Research Fellowship (SURF) Symposium

Nanocrystalline formulations of anti-tumor drugs have been shown to improve desirable characteristics as well as increase the efficacy of delivery. However, the improvements seen are not strong enough to eradicate tumors and there exists a need to better understand how the drug particles move about and release in the body. The use of fluorophores incorporated into substrates allows for highly sensitive and resolute imaging in the body without the need for radioisotopes. This research aims to utilize quenching characteristics of fluorescein in order to provide pharmacokinetic information to aid in the improvement of nanoparticulate delivery formulations. Nanocrystal formulations of paclitaxel …
