Development And Evaluation Of Therapeutics In The Setting Of Radiation Injury, Karin Emmons Thompson 2010 University of Tennessee Health Science Center

Development And Evaluation Of Therapeutics In The Setting Of Radiation Injury, Karin Emmons Thompson

Theses and Dissertations (ETD)

The possibility of an incident involving radiation exposure is at the forefront of public attention in the current global environment. With a greater number of entities possessing nuclear weapons and increased demand for nuclear power, the concern for uncontained exposure to radiation is increasing. In light of these developments, the need for treatments that may be easily stored and administered to large numbers of people who have been exposed to high doses of total body irradiation (TBI) is more urgent than ever before.

Our goal was to identify and develop novel, drug-like small molecules that would exhibit radiomitigating activity for ...


Preliminary Studies Into Dna Binding Capabilities Of Ruthenium Nitro Nitrosyl As Anti-Tumor Pro-Drugs, Natasha Hansson 2010 Seton Hall University

Preliminary Studies Into Dna Binding Capabilities Of Ruthenium Nitro Nitrosyl As Anti-Tumor Pro-Drugs, Natasha Hansson

Seton Hall University Dissertations and Theses (ETDs)

The complex [Ru(bpy)z(NO)(N02)](PF6)2 was investigated as a potential anti­ tumor drug option. The nitrosyl group was displaced by reaction with azide ion in acetone to yield the solvento complex in situ. The products isolated from addition of a solution or slurry of guanine, adenine, cytosine or thiamine to the resulting [Ru(bpy)(N02)(acetone)t were investigated by electronic absorption spectroscopy, infra­ 1 red spectroscopy, H NMR spectroscopy and cyclic voltammetry. The results of the studies showed that guanine, adenine and thiamine form adducts with Ru(bpy)z(N02)(acetone)t. However, each base ...

Failure To Ubiquitinate C-Met Leads To Hyperactivation Of Mtor Signaling In A Mouse Model Of Autosomal Dominant Polycystic Kidney Disease, Shan Qin, Mary Taglienti, Surya M. Nauli, Leah Contrino, Ayumi Takakura, Jing Zhou, Jordan A. Kreidberg

Pharmacy Faculty Articles and Research

Autosomal dominant polycystic kidney disease (ADPKD) is a common inherited disorder that is caused by mutations at two loci, polycystin 1 (PKD1) and polycystin 2 (PKD2). It is characterized by the formation of multiple cysts in the kidneys that can lead to chronic renal failure. Previous studies have suggested a role for hyperactivation of mammalian target of rapamycin (mTOR) in cystogenesis, but the etiology of mTOR hyperactivation has not been fully elucidated. In this report we have shown that mTOR is hyperactivated. in Pkd1-null mouse cells due to failure of the HGF receptor c-Met to be properly ubiquitinated and subsequently ...

Active targeting of a drug carrier to a specific target site is crucial to provide a safe and efficient delivery of therapeutics and imaging contrast agents. E-selectin expression is induced on the endothelial cell surface of vessels in response to inflammatory stimuli but is absent in the normal vessels. Thus, E-selectin is an attractive molecular target, and high affinity ligands for E-selectin could be powerful tools for the delivery of therapeutics and/or imaging agents to inflamed vessels. In this study, we identified a thiophosphate modified aptamer (thioaptamer, TA) against E-selectin (ESTA-1) by employing a two-step selection strategy: a recombinant ...


Synthesis Of A Water Soluble Resveratrol Derivative As A Potential Anti-Cancer Drug., Augustine Essel 2010 East Tennessee State University

Synthesis Of A Water Soluble Resveratrol Derivative As A Potential Anti-Cancer Drug., Augustine Essel

Electronic Theses and Dissertations

Research on development of water soluble anti-cancer drugs is one of the great challenges of modern medicinal chemistry. Resveratrol (Res) is one of the many phytoalexins producing stilbenoids present in several medicinal plants, grape skin, peanuts, and red wine. It has been found to exhibit anti-cancer, anti-inflammatory, and anti-oxidant properties. Water solubility and bioavailability are some of the setbacks of this interesting compound. In view of this, effort has been made to synthesize amino acid derivative of resveratrol to improve its bioavailability and solubility in water. Methyl 4-{-[(1E)-2-(3, 5-dihydroxyphenyl)-ethenyl] - phenoxy} butyrate (7), a novel ester intermediate ...


Tdiscovery And Development Of Novel Therapeutic Agents For Advanced Melanoma, Zhao Wang 2010 University of Tennessee Health Science Center

Tdiscovery And Development Of Novel Therapeutic Agents For Advanced Melanoma, Zhao Wang

Theses and Dissertations (ETD)

Malignant melanoma is the most dangerous form of skin cancer and accounts for about 75% of skin cancer deaths. Once diagnosed at the metastatic stage, it has a very poor prognosis with a median survival rate of 6 months and a 5-year survival rate of less than 5%. In addition, melanoma has become an important public health hazard owing to its rising incidence, which has been well documented over the past 50 years. Currently there is no effective way to treat melanoma. It is highly resistant to existing chemotherapy, radiotherapy, and immunotherapy. Over the past 30 years, only two drugs ...


Discovery Of Quinic Acid Derivatives As Oral Anti-Inflammatory Agents, Kui Zeng 2010 University of Tennessee Health Science Center

Discovery Of Quinic Acid Derivatives As Oral Anti-Inflammatory Agents, Kui Zeng

Theses and Dissertations (ETD)

Quinic acid (QA) esters found in hot water extracts of Uncaria tomentosa (a.k.a. Cat’s claw) exert anti-inflammatory activity through mechanisms involving inhibition of the pro-inflammatory transcription factor nuclear factor kappa B (NF-κB). Herein, we described the synthesis and biological testing of novel QA derivatives. Inhibition of NF-κB was assessed using A549 (Type II alveolar epithelial-like) cells that stably express a secreted alkaline phosphatase (SEAP) reporter driven by an NF-κB response element. A549- NF-κB cells were stimulated with TNF-α (10 ng/mL) in the presence or absence of QA derivative for 18 hours followed by measurement of SEAP ...

Cdc42, a member of the Rho family of GTPases, has been shown to play a role in cell adhesion, cytoskeletal arrangement, phagocytosis and cell motility and migration, in addition to a host of other diverse biological processes. The function of Rho-family GTPases in disease pathogenesis has been well established and identification of small, cell permeable molecules that selectively and reversibly regulate Rho GTPases is of high scientific and potentially therapeutic interest. There has been limited success in identifying inhibitors that specifically interact with small Rho family GTPases. The identified probe, ML141 (CID-2950007), is demonstrated to be a potent, selective and ...

Chromatin remodeling is an essential part of transcription initiation. We show that at heat shock gene promoters functional interactions between individual ATP-dependent chromatin remodeling complexes play critical role in both nucleosome displacement and Pol II recruitment. Using HSP12, HSP82 and SSA4 gene promoters as reporters, we demonstrated that while inactivation of SNF2, a critical ATPase of the SWI/SNF complex, primarily affects the HSP12 promoter, depletion of STH1- a SNF2 homolog from the RSC complex reduces histone displacement and abolishes the Pol II recruitment at all three promoters. From these results, we conclude that redundancy between SWI/SNF and RSC ...


Computational Prediction And Analysis Of The Napp – Dr6 Interaction: Implications For Alzheimer's Research, Joseph Audie, Sergei Y. Ponomarev 2010 Sacred Heart University

Computational Prediction And Analysis Of The Napp – Dr6 Interaction: Implications For Alzheimer's Research, Joseph Audie, Sergei Y. Ponomarev

Chemistry & Physics Faculty Publications

Alzheimer's disease (AD) is a progressive neurodegenerative disorder that involves a devastating clinical course and lacks an effective treatment. A biochemical model for neuronal development, recently proposed by Nikolaev and co-workers, hinges on a novel protein-protein interaction between the death cell receptor six (DR6) ectodomain and an N-terminal fragment of amyloid precursor protein (NAPP). The model provides a coherent and satisfying framework for better understanding AD pathophysiology. Moreover, the DR6-NAPP interaction offers a tempting target for novel pharmacological intervention. Given all of this, we constructed a structural model of the DR6-NAPP interaction using the neurotrophin p75 receptor as a ...

Development Of Cytarabine Prodrugs And Delivery Systems For Leukemia Treatment, Bhupender S. Chhikara, Keykavous Parang

Pharmacy Faculty Articles and Research

Importance of the field: Cytarabine is a polar nucleoside drug used for the treatment of myeloid leukemia and non-Hodgkin’s lymphoma. The drug has a short plasma half-life, low stability, and limited bioavailability. Overdosing of patients with continuous infusions may lead to side effects. Thus, various prodrug strategies and delivery systems have been extensively explored to enhance the half-life, stability, and delivery of cytarabine. Among the recent cytarabine prodrugs, amino acid conjugate ValCytarabine and fatty acid derivative CP-4055 (in phase 3 trials) have been investigated for the treatment of leukemia and solid tumors, respectively. Alternatively, delivery systems of cytarabine have ...
