Constituent Partitioning Consensus Docking Models And Application In Drug Discovery, Rainer Metcalf
Constituent Partitioning Consensus Docking Models And Application In Drug Discovery, Rainer Metcalf
USF Tampa Graduate Theses and Dissertations
This work expounds on some of the current computational tools and programs available and the best practices associated with their use. A high-level introduction, intended for both novices and the semi-experienced, focusing on the more common programs used in scientific literature is the scope of this topic. Both classical and quantum techniques are described. Classical methodologies include Molecular Dynamics, Monte Carlo, energy minimization methods, molecular docking, low-mode, and homology modeling. Quantum chemistry techniques are also discussed encompassing Hartree-Fock, Post-Hartree-Fock theories, and Density Functional Theory along with associated basis sets.
Along with established methodologies, novel theoretical methods are introduced for furthering …
The Role Of Atypical Protein Kinase C In Colorectal Cancer Cells Carcinogenesis, S M Anisul Islam
The Role Of Atypical Protein Kinase C In Colorectal Cancer Cells Carcinogenesis, S M Anisul Islam
USF Tampa Graduate Theses and Dissertations
Colorectal cancer (CRC) is the third most common malignancy and the fourth most common cause of cancer-related death worldwide. CRC is a life-threatening disease due to therapy-resistant cancerous cells. The exact mechanisms of cell growth, survival, metastasis and inter & intracellular signaling pathways involved in CRC are still a significant challenge. Moreover, the treatment of metastatic CRC considered palliative for many years aimed for an improved life, with little hope of a cure, highlighting the need for developing novel targeted therapy for CRC. Hence, investigating new molecular mechanism(s) that lead to colorectal carcinogenesis may give insight into the therapeutic target. …
Targeting Bacterial Resistance And Cancer Metastasis: A Structure Based Approach, Kyle Galen Kroeck
Targeting Bacterial Resistance And Cancer Metastasis: A Structure Based Approach, Kyle Galen Kroeck
USF Tampa Graduate Theses and Dissertations
Current research in pharmaceutical development commonly utilizes a profusion of methods in molecular modeling in order to probe intricate biological problems. Many original and promising compounds have been identified and developed by integrating experimental and computational methods. Structural biology utilizes many different research techniques including x-ray crystallography, NMR, and electron microscopy in order to develop molecular models of macromolecules that are of biological interest. Such techniques can be used in conjunction with molecular docking, which utilizes those molecular models in order to target macromolecules of therapeutic interest by computationally analyzing the conformations adopted by ligands upon interaction with a desired …
An Investigation Into The Heterogeneity Of Insect Arylalkylamine N-Acyltransferases, Brian G. O'Flynn
An Investigation Into The Heterogeneity Of Insect Arylalkylamine N-Acyltransferases, Brian G. O'Flynn
USF Tampa Graduate Theses and Dissertations
Arylalkylamine N-acyltransferases (AANATs) have in recent years been suggested as potential new insecticide targets. These promiscuous enzymes are involved in the N-acylation of biogenic amines to form N-acylamides. Mammalian AANAT is predominantly associated with circadian rhythm regulation, as it catalyzes the formation of N-acetylserotonin, the precursor of melatonin, from serotonin. In insects, this process is a key step in melanism, as well as hardening of the cuticle, removal of biogenic amines, and in the biosynthesis of fatty acid amides. The unique nature of each insect AANAT (iAANAT) isoform characterized indicates that while catalyzing similar reactions, each insect accommodates …
Hybrid Fusion Protein For Inhibition Of Multiple Proteases For Chronic Wound Healing, Graham L. Strauss
Hybrid Fusion Protein For Inhibition Of Multiple Proteases For Chronic Wound Healing, Graham L. Strauss
USF Tampa Graduate Theses and Dissertations
Many diseases display a multitude of relevant factors that contribute to the persistence of the disease and difficulty treating it. The multifactorial characteristics of some diseases lead to the requirement of combination of treatments in order to restore health. The latter may necessitate the mixing of treatments, medications, and therapeutics to first halt the disease, then assist the human body in returning itself to a state of normality. For example, chronic wounds exhibit this multifactor characteristic in which there exist many factors that lead to the body’s inability to properly heal in a timely manner. This presents a further threat …
A Small Rna And Dna Binding Protein Contribute To Biofilm Development In Bartonella Henselae, Udoka Okaro
A Small Rna And Dna Binding Protein Contribute To Biofilm Development In Bartonella Henselae, Udoka Okaro
USF Tampa Graduate Theses and Dissertations
A biofilm, which is associated with 80% of chronic infections in humans, is formed when bacteria aggregate, attach to a substrate and secrete a matrix protecting the bacteria from host cell defenses and antibiotics. Bartonella henselae (B. henselae) is the causative agent of cat scratch disease, persistent bacteremia, and one of the most frequently reported causes of blood-culture negative endocarditis (BCNE) in patients. The ability of B. henselae to adhere to the heart valve, form a biofilm and vegetation to cause endocarditis increases the morbidity and mortality rate in infected patients. The presence of a trimeric autotransporter adhesin (TAA) called …

Irrespective of plentiful efforts to enhance primary prevention and early detection, the number of melanoma cases in the United States has increased steadily over the past 30 years, thus greatly affecting public health and the economy. We have investigated the effects of five novel aPKC inhibitors; 2-acetyl-1,3-cyclopentanedione (ACPD), 3,4-Diaminonaphthalene-2,7-disulfonic acid (DNDA), [4-(5-amino-4-carbamoylimidazol-1-yl)-2,3-dihydroxycyclopentyl] methyl dihydrogen phosphate (ICA-1T) along with its nucleoside analog 5-amino-1-((1R,2S,3S,4R)-2,3-dihydroxy-4-methylcyclopentyl)-1H-imidazole-4-carboxamide (ICA-1S) and 8-hydroxy-1,3,6-naphthalenetrisulfonic acid (ζ-Stat) on cell proliferation, apoptosis, migration and invasion of two malignant melanoma cell lines compared to normal melanocyte cell lines. Molecular docking data suggested that both ACPD and DNDA specifically bind to protein kinase …
