Synthesis And Cytotoxicity Of Azaheterocyclic Compounds, Keyur M. Pandya

Theses and Dissertations

Multicomponent coupling reactions (MCRs) have been known for a long time and one such reaction that utilizes isocyanides is Passerini reaction. It is a powerful tool to synthesize libraries of different compounds. Azaheterocyclic compounds play an important role in medicinal chemistry. Motifs such as imidazoles, piperazines, pyrazoles, pyridines, triazoles, etc. are routinely observed in several compounds of pharmacological interest. Several natural products also contain these motifs in them. We have undertaken a library synthesis of heterocyclic molecules driven by our group's long-standing interest of synthesizing medicinally relevant small molecules employing green chemistry techniques.

This thesis details our efforts on the …

A Study Of Albendazole And Artemisinin Drugs Under Electrochemical Oxidation, Zahilis A. Mazzochette

Theses and Dissertations

This work is aimed to investigate the metabolic behavior of albendazole and artemisinin. The electrochemical oxidation and reduction of these drugs were performed on electrode materials to mimic their metabolism in vivo using cyclic voltammetry and bulk electrolysis analysis. The oxidation of albendazole on gold electrode surface yielded albendazole sulfoxide and albendazole sulfone which are the main metabolites of this drug in vivo. Reduction of artemisinin on glassy carbon (GC) electrode surface yielded dihydroartemisinin and deoxy artemisinin. The formation of these products was monitored using liquid chromatography and mass spectrometry techniques. The redox processes for both drugs were shown to …

Novel Aminobenzoboroxoles As Potential Anti-Cancer Agents, Bhawankumar Pravinchandra Patel

Theses and Dissertations

Boronic acids are a promising class of compounds due to their wide range of applications in medicinal and materials chemistry, and as coupling agents in organic synthesis. B-hydroxy-1,2-oxaborolanes (benzoboroxoles) are categorized as cyclic boronic acid derivatives and they are very important organic molecules because of their metabolic stability and their ability to undergo important C-C bond forming reactions such as Suzuki cross coupling. Several of these cyclic boronic acids are found to have promising pharmacological properties as antifungal, antimalarial and anti-inflammatory agents. However, based on the literature reports, synthesis of highly functionalized benzoboroxoles is typically cumbersome and not very conducive …

Components In Aqueous Hibiscus Rosa-Sinensis Flower Extract Inhibit In Vitro Melanoma Cell Growth, Karina H. Goldberg, Ariel C. Yin, Archana Mupparapu, Edward P. Retzbach, Gary S. Goldberg, Catherine F. Yang

Skin cancer is extremely common, and melanoma causes about 80% of skin cancer deaths. In fact, melanoma kills over 50 thousand people around the world each year, and these numbers are rising. Clearly, standard treatments are not effectively treating melanoma, and alternative therapies are needed to address this problem. Hibiscus tea has been noted to have medicinal properties, including anticancer effects. Extracts from Hibiscus have been shown to inhibit the growth of a variety of cancer cells. In particular, recent studies found that polyphenols extracted from Hibiscus sabdariffa by organic solvents can inhibit melanoma cell growth. However, effects of aqueous …

Plant Lectin Can Target Receptors Containing Sialic Acid, Exemplified By Podoplanin, To Inhibit Transformed Cell Growth And Migration, Jhon Ochoa-Alvarez, Harini Krishnan, Yongquan Shen, Nimish Acharya, Min Han, Dean Mcnulty, Hitoki Hasegawa

Cancer is a leading cause of death of men and women worldwide. Tumor cell motility contributes to metastatic invasion that causes the vast majority of cancer deaths. Extracellular receptors modified by α2,3-sialic acids that promote this motility can serve as ideal chemotherapeutic targets. For example, the extracellular domain of the mucin receptor podoplanin (PDPN) is highly O-glycosylated with α2,3-sialic acid linked to galactose. PDPN is activated by endogenous ligands to induce tumor cell motility and metastasis. Dietary lectins that target proteins containing α2,3-sialic acid inhibit tumor cell growth. However, anti-cancer lectins that have been examined thus far target receptors …
