A huge number of compounds are widely distributed in nature and many of these possess medicinal/biological/pharmacological activity. Curcumin, a polyphenol derived from the rhizomes (underground stems) of Curcuma longa Linn (a member of the ginger family, commonly known as turmeric) is a culinary spice and therapeutic used in India for thousands of years to induce color and flavor in food as well as to treat a wide array of diseases. The origin of turmeric as spice and folklore medicine is so old that it is lost in legend. Curcumin has many beneficial pharmacological effects which includes, but are not limited …
Inhibition Of The Thioesterase Activity Of Human Fatty Acid Synthase By 1,4- And 9,10-Diones, Herman H. Odens
Inhibition Of The Thioesterase Activity Of Human Fatty Acid Synthase By 1,4- And 9,10-Diones, Herman H. Odens

Fatty acid synthase (FASN) is the enzyme that synthesizes fatty acids de novo in human cells. Although FASN is generally expressed at low levels in most normal tissues, its expression is highly upregulated in many cancers. Consistent with this notion, inhibition of FASN activity has demonstrated potential to halt proliferation and induce cell death in vitro and to block tumor growth in vivo. Consequently, FASN is widely recognized as a valuable therapeutic target. In this report, we describe a variety of 1,4-quinones and 9,10- anthraquinones, including several natural compounds and some newly synthesized compounds, that potently inhibit the thioesterase (TE) …
Medicinal History Of North American Veratrum, Christopher M. Chandler, Owen M. Mcdougal
Medicinal History Of North American Veratrum, Christopher M. Chandler, Owen M. Mcdougal
Chemistry and Biochemistry Faculty Publications and Presentations
Plants belonging to the genus Veratrum have been used throughout history for their medicinal properties. During the nineteenth and twentieth centuries, phytochemical investigations revealed a host of steroidal alkaloids in Veratrum species, some of which are potent bioactives. This review discusses Veratrum species that grow in North America with a focus on the medicinal history of these plants and the steroidal alkaloids they contain. While significant reviews have been devoted to singularly describing the plant species within the genus Veratrum (botany), the staggering breadth of alkaloids isolated from these and related plants (phytochemistry), and the intricacies of how the various …

Tubulin and heat shock protein 27 (Hsp27) are well-characterized molecular targets for anti-cancer drug development. We previously identified lead compounds that inhibited both Hsp27 and tubulin. These compounds exhibited extensive anti-cancer activities against the proliferation of various human cancer cell lines. In the current study, a systematic ligand based structural optimization led to new analogs that significantly inhibited the growth of a panel of breast cancer cell lines. Furthermore, the most potent compounds were examined with tubulin polymerization assay and Hsp27 chaperone activity assay. The compounds showed potent tubulin polymerization inhibition but no Hsp27 inhibitory effect. The structural optimization dissected …

ZnO nanoparticles (NP) are extensively used in numerous nanotechnology applications; however, they also happen to be one of the most toxic nanomaterials. This raises significant environmental and health concerns and calls for the need to develop new synthetic approaches to produce safer ZnO NP, while preserving their attractive optical, electronic, and structural properties. In this work, we demonstrate that the cytotoxicity of ZnO NP can be tailored by modifying their surface-bound chemical groups, while maintaining the core ZnO structure and related properties. Two equally sized (9.26 ± 0.11 nm) ZnO NP samples were synthesized from the same zinc acetate precursor …
Functionalization And Modification Of Naphthaquinone Analogs As Her2 Kinase Inhibitors, Divya Jyothi Lella

Masters Theses & Specialist Projects
HER2 overexpression in breast cancer tumors predicts lower overall survival. Because of the aggressive nature of HER2 tumors and the association with metastatic disease, the HER2 receptor holds great promise as a therapeutic target in metastatic breast cancer. We are developing small molecule inhibitors that bind to the ATP binding site of the tyrosine kinase domain in order to inhibit tyrosine auto-phosphorylation. This process controls biological pathways that mediate the cell growth. In normal cells this process is highly controlled. We are targeting the modification of the side chain of the hydroxy methyl group of 2-Hydroxy methyl-5,8-dimethoxy-1,4-naphthaquinone. These compounds should …

As biotechnology advances rapidly, a tremendous amount of cancer genetic data has become available, providing an unprecedented opportunity for understanding the genetic mechanisms of cancer. To understand the effects of duplications and deletions on cancer progression, two genomes (normal and tumor) were sequenced from each of five stomach cancer patients in different stages (I, II, III and IV). We developed a phylogenetic model for analyzing stomach cancer data. The model assumes that duplication and deletion occur in accordance with a continuous time Markov Chain along the branches of a phylogenetic tree attached with five extended branches leading to the tumor …
Lost In Translation: Animal Models And Clinical Trials In Cancer Treatment, Isabella W.Y. Mak, Nathan Evaniew, Michelle Ghert
Lost In Translation: Animal Models And Clinical Trials In Cancer Treatment, Isabella W.Y. Mak, Nathan Evaniew, Michelle Ghert
Human Clinical Trials Collection
Due to practical and ethical concerns associated with human experimentation, animal models have been essential in cancer research. However, the average rate of successful translation from animal models to clinical cancer trials is less than 8%. Animal models are limited in their ability to mimic the extremely complex process of human carcinogenesis, physiology and progression. Therefore the safety and efficacy identified in animal studies is generally not translated to human trials. Animal models can serve as an important source of in vivo information, but alternative translational approaches have emerged that may eventually replace the link between in vitro studies and …

Raman spectroscopy is a non-destructive, non-invasive, rapid and economical technique which has the potential to be an excellent method for the diagnosis of cancer and understanding disease progression through retrospective studies of archived tissue samples. Historically, biobanks are generally comprised of formalin fixed paraffin preserved tissue and as a result these specimens are often used in spectroscopic research. Tissue in this state has to be dewaxed prior to Raman analysis to reduce paraffin contributions in the spectra. However, although the procedures are derived from histopathological clinical practice, the efficacy of the dewaxing procedures that are currently employed is questionable. Ineffective …

Australian Institute for Innovative Materials - Papers
In this study we present the synthesis of a new theranostic system consisting of a core-shell structured nanoceramic-drug conjugate that can potentially combine chemotherapeutic, targeting, diagnostic and radio dose enhancing features in cancer treatment. The conjugate is made of α-Bi2O3 nanoparticles (NPs) which were first coated with (3-aminopropyl)trimethoxysilane (APTMS) to form a core-shell structure and then attached with methotrexate (MTX) through amidation between the amine moieties on the shell and the carboxylic acid groups on MTX. While α-Bi2O3 NPs with high effective atomic number can serve as both contrast agent and radiosensitiser in dose enhancement radiation therapy, MTX as an …
