This study reports the synthesis, spectroscopic characterization, and biological evaluation of a novel moxifloxacin hydrazide derivative (MOX-H) and its metal complexes with Co(II), Ni(II), Cu(II), VO(IV), and Gd(III). The ligand was synthesized by hydrazinolysis of moxifloxacin hydrochloride, and the resulting hydrazide was subsequently complexed with the respective metal salts. The interaction between MOX-H and the metal ions yielded the corresponding complexes, formulated as [Co(H2O)Cl(MOX-H)2]Cl & centerdot;2.5H2O, [Ni(H2O)Cl(MOX-H)2]Cl.4.5H2O, [VO(MOX-H)2]SO4.3.5H2O, [Gd (H2O)(MOX-H)2(NO3)2]NO3.2H2O, and [Cu(MOX-H)2(H2O)Cl]Cl & centerdot;xH2O (where x = 2, 2.5, 0.5, for products synthesized via template, microwave-assisted, and hydrothermal methods, respectively). The synthesized analogues were characterized by elemental analysis (CHN), FT-IR, …

In this study, we synthesized a novel trimethoprim derivative, 4-(((2-amino-5-(3,4,5-trimethoxybenzyl) pyrimidine-4-yl)imino)methyl)benzene-1,3-diol (HD), by the reaction of trimethoprim with 2,4-dihydroxybenzaldehyde. We then prepared metal complexes of this derivative with Cu(II), Co(II), Ni(II), Ag(I), and Zn(II) and functionalized them with ZnO and Au nanoparticles. Their structures were confirmed through 1H NMR, mass spectrometry, FTIR, conductivity, thermal analysis, magnetic susceptibility, X-ray diffraction, UV-Vis spectroscopy, and TEM, revealing octahedral geometries for all complexes. Surface features were investigated using density functional theory (DFT) analysis. Pharmacokinetic parameters and target enzymes for HD and its complexes were computed using the SwissADME web tool, with the BOILED-Egg model …

Recent Studies On The Synthesis Of Medicinal Molecules., Paige Monsen
Electronic Theses and Dissertations
Medicinal chemistry interfaces synthetic organic chemistry, natural product chemistry and chemical biology, with a goal of yielding therapeutic agents. Natural products or compounds derived from natural sources such as plants, animals, and microorganisms, are often biologically active and render that compound a likely drug lead. For thousands of years humankind has utilized natural products for medicinal purposes and consequently scientists take advantage of both these compounds’ core structural characteristics and their modes of actions on selected targets as inspiration to develop therapeutics. Because the total synthesis of such complex molecules can be cumbersome and expensive, semi-synthetic methods on isolated natural …
Synthesis Of Novel Thiazole And Pyrazole Derivatives As Antimicrobial And Anticancer Agents, Rawan Saleh Alnufaie
Synthesis Of Novel Thiazole And Pyrazole Derivatives As Antimicrobial And Anticancer Agents, Rawan Saleh Alnufaie
Student Theses and Dissertations
This thesis contains three chapters. In Chapters One and Two, we report the synthesis of new pyrazole derivatives by using naphthalene-derived and coumarin-derived aldehydes. We have synthesized 61 different pyrazole derivatives in good yield. In the third chapter, a new methodology to synthesize thiazole derivatives is reported. In this methodology, the reaction was performed without column purification and work-up. Readily available starting materials were used with mild reaction conditions. Acetic acid was used as a solvent in this reaction to synthesize 34 new compounds. All these compounds were characterized by using NMR spectroscopy and mass spectrometry. These compounds were tested …
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 …
A Novel Method For Synthesis Of Hydroxytyrosol, Emmanuel Onobun
A Novel Method For Synthesis Of Hydroxytyrosol, Emmanuel Onobun
Electronic Theses and Dissertations
Hydroxytyrosol, 3,4-dihydroxyphenolethanol, a naturally occurring polyphenol most common in olive tree (Olea europaea), is one of the most effective member of the polyphenols family, because of its remarkable antioxidant activity, its ability to inhibit oxidation of low density lipids (LDL), and its protection against DNA oxidative damage. Hydroxytyrosol, which is widely used in cosmetics and food supplements industries, can be purchased as an olive oil extract that contains low concentration of hydroxytyrosol besides other polyphenols. The price and low natural abundance of hydroxytyrosol make alternative synthetic sources very attractive. In this research, a novel method for the synthesis of pure …
Relative Reaction Rates Of The Amino Acids Cysteine, Methionine, And Histidine With Analogs Of The Anti-Cancer Drug Cisplatin, Cynthia A. Tope
Relative Reaction Rates Of The Amino Acids Cysteine, Methionine, And Histidine With Analogs Of The Anti-Cancer Drug Cisplatin, Cynthia A. Tope
Mahurin Honors College Capstone Experience/Thesis Projects
We are studying the reaction of analogs of the anticancer drug cisplatin with amino acids that differ in size and shape. The reaction of cisplatin with proteins likely precedes reaction with DNA in the body, forming a variety of products that may be toxic to the human body. The size and shape of the platinum(II) complexes often affects the rate of reaction with proteins, more so than with DNA. In this study, triamine cisplatin analogs are reacted with the amino acids cysteine, methionine, and histidine simultaneously. These reactions are monitored by NMR spectroscopy. The effect of the bulk of the …
Reaction Rates Of Amino Acids With Derivatives Of The Anticancer Drug Cisplatin, Celia Jess Whelan
Reaction Rates Of Amino Acids With Derivatives Of The Anticancer Drug Cisplatin, Celia Jess Whelan
Mahurin Honors College Capstone Experience/Thesis Projects
We are studying reactions of cisplatin derivatives, which differ in both size and shape, with various amino acids. When reaction with DNA occurs, apoptosis is observed, ideally leading to termination of the cancer. Due to the affinity of cisplatin for sulfur-containing amino acids, reaction with proteins may occur prior to access to the DNA, producing a large array of products, which could potentially be toxic to the human body. Both the size and shape of the platinum complexes often affect the reactions with protein targets more so than with DNA targets. By performing reactions of specific amino acids targets with …
