Interaction Of A Platinum Triamine Complex Having A Seven-Membered Chelate Ring With N-Acetyl-Lmethionine And Guanosine 5'-Monophosphate, Jae Ko
Masters Theses & Specialist Projects
In the 1960s, Rosenberg and his colleagues confirmed the anti-cancer activity of cisplatin. Although cisplatin was capable of killing testicular cancer cells there were also serious side effects. It was necessary to find alternate ways of overcoming side effects, and soon many researchers have discovered novel platinum compounds that show similar reactivity. Recently, replacing one chloride group to a heterocyclic amine group showed significant cytotoxicity with a different binding activity than cisplatin. Previously in our lab, [Pt(Me5dien)(NO3)]+ and [Pt(Et2dien)Cl]+ have been synthesized and reacted with NAcetyl- L-methionine (N-AcMet) and Guanosine 5’-monophosphate (5’-GMP) showed unusual reactivity. Unlike most previously studied platinum …
Photochemical Investigation Of High-Valent Metal-Oxo Intermediates Containing Corrole And Light-Harvesting Porphyrin Ligands, Jonathan Malone
Photochemical Investigation Of High-Valent Metal-Oxo Intermediates Containing Corrole And Light-Harvesting Porphyrin Ligands, Jonathan Malone
Masters Theses & Specialist Projects
In enzymatic and synthetic catalytic oxidations, high-valent iron-oxo intermediates play a vital role as the active oxidant. In this regard, many synthetic metal catalysts are designed as biomimetic models to resemble the active site of Cytochrome P450 enzymes (P450) which are the predominant oxidation catalysts in nature. Vitamin B12 cofactors, with a corrole-like structure corrin, are also utilized in some of the more difficult reactions in nature such as rearrangement and reductase reactions.
In this work, application of the promising photochemical method to corrolecontaining ligands systems showed much success in the generation of manganese(V)-oxo corrole intermediates using two electron-deficient corrole …
Functionalization And Modification Of Naphthaquinone Analogs As Her2 Kinase Inhibitors, Divya Jyothi Lella
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 …
Ionic Conductivity In Non-Ionic Compounds, Usha Kranthi Avala
Ionic Conductivity In Non-Ionic Compounds, Usha Kranthi Avala
Masters Theses & Specialist Projects
The main objective of this work is to investigate the ionic conductivity of the drugs under certain conditions and also to compare the ionic conductivities of drugs determined by single surface sensors and parallel plate sensors. The ionic conductivity of various materials at their pre-melt and melt states are studied in order to further study a recently discovered phenomenon. Polar solids like Lidocaine, Ketoconazole, Procainamide and Nifedipine were examined in this study. Experimental studies show an increase in ionic conductivity in both pre-melt (20 -30 °C below melting temperature) and melt transition regions. Results of ionic conductivity of both parallel …
Inhibition Of Cysteine Protease By Platinum (Ii) Diamine Complexes, Chaitanya Rapolu
Inhibition Of Cysteine Protease By Platinum (Ii) Diamine Complexes, Chaitanya Rapolu
Masters Theses & Specialist Projects
Chemotherapy is the first line of treatment used in cancer. Chemotherapy drugs such as cisplatin, carboplatin and oxaliplatin are used in treatment. Cisplatin enters the cell through copper transporter CTR1 by passive diffusion and bind to DNA and proteins. Cisplatin is found to inhibit several enzymes targeting cysteine, histidine and methionine residues, which are expected to be responsible for its anticancer activity. A better understanding of how the size and shape and leaving ligands of platinum complexes affect cysteine protease, papain enzyme are studied. This could give new ways to optimize anticancer activity. The activity of papain enzyme was measured …
