Synthesis, In Vitro Characterization And Applications Of Novel 8-Aminoquinoline Fluorescent Probes, Adonis Mcqueen

USF Tampa Graduate Theses and Dissertations

Malaria is a parasitic disease that is caused by the plasmodium parasite. Plasmodium infection has affected man for thousands of years. With advances in drug discovery over the past century, malaria has evolved to possess resistance to most mainline therapeutics. This war of drug discovery vs plasmodium evolution continues to be fought to this very day, with attempts to eradicate malaria worldwide. Frontline treatments such as chloroquine, artemisinin, and atovaquone/proguanil have all seen parasitic resistance in strains of P. vivax as well as P. falciparum. While plasmodium possesses resistance to most classes of anti-malarials, the 8-aminoquinoline (8-AQ) class has …

Development Of Orally Bioavailable 4(1H)-Quinolones And 1,2,3,4-Tetrahydroacridin-9(10H)-Ones With Potent Anti-Malarial Activity, Jordany Richarlson Maignan

USF Tampa Graduate Theses and Dissertations

Although Malaria rates are on the decline due to the efforts of the World Health Organization and other organizations dedicated to the eradication of this disease, a relaxed attitude towards the development of new antimalarial entities would be flawed. Due to the emergence of resistance in the parasite, the almost 50% world-wide reduction in malarial death rates that have been produced over the past 15 years are threatening to be lost

New drugs are urgently needed and our approach focuses on the re-evaluation and optimization of the historic antimalarial ICI 56,780. Due to its causal prophylactic activity, along with its …

Design Of Novel Inhibitors For Infectious Diseases Using Structure-Based Drug Design: Virtual Screening, Homology Modeling And Molecular Dynamics, Divya Ramamoorthy

USF Tampa Graduate Theses and Dissertations

The main aim of the study in this thesis was to use structure-based protocols to design new drugs for enzymes, DXS and DXR in the non mevalonate pathway. Another aim of this study was to identify the dimer interface in E.coli FabH as an allosteric binding site for designing new class of anti-infective drugs. We have attempted to identify potential inhibitors for DXS by docking the NCI Diversity set compounds, compound libraries available from GSK-MMV and St. Jude's Children's research center. FabH dimer interface has been identified as a potential target using SiteMap, Alanine mutagenesis and docking studies.

The first …
