Metabolism of pyrrolizidine alkaloids by ruminal microbes

Creator:: Hovermale, Jeannette Talbot
Abstract:: The plant Senecio jacobaea (tansy ragwort) produces several macrocyclic pyrrolizidine alkaloids which cause irreversible liver cirrhosis. All of the pyrrolizidine alkaloids in Senecio jacobaea are macrocyclic diesters of the necine base retronecine, with the two most predominant being seneciphylline and jacobine. Unlike horses and cattle, sheep and goats are generally...

A new general method for the optimization of HPLC ternary of pseudo-quaternary mobile phases and the separation of two new metabolites of nefopam from greyhound urine

Creator:: Chen, Hsiao and Chen, Xiao
Abstract:: A new general method is developed for the optimization of HPLC ternary or pseudo-quaternary mobile phases which are represented by the trilinear coordinate system. This method can predict the global optimum of the mobile phase composition. The global optimum composition along each edge of the triangle and the corresponding selectivity...

Analytical chemistry of pentazocine metabolites produced by the greyhound

Creator:: Xiao, Guang
Abstract:: This thesis concerns itself mainly with analytical methods development and analytical applications in the field of drug metabolism studies. The determination of the analgesic pentazocine and its metabolites in the greyhound are studied. Pentazocine and all of its possible metabolites are isolated from the greyhound urine by a the multi-solvent...

Total Synthesis of Cephalotaxus Alkaloids and Synthetic Studies toward Bazzanin K

Creator:: Ju, Xuan
Abstract:: Dearomatization reactions exist broadly in biosynthesis and chemical synthesis. The highly functionalized atoms of arenes can be masked by it aromaticity, and upon dearomatization, those reactive atoms can be readily applied to bond formation and further manipulation. The total synthesis of (–)-cephalotaxine and (–)- homoharringtonine is described via an oxidative...

Progress Towards the Total Synthesis of Bazzanin K

Creator:: Salvo, Patrick
Abstract:: Molecular chirality plays a critical role in chemistry, biology, and medicine. To study and better understand conformational chirality, it is necessary to obtain structurally interesting molecules that exhibit this form of chirality. Our lab utilizes total synthesis and methodological development to obtain conformationally chiral natural products of interest. We believe...

The use of the Diels-Alder reaction in asymmetric synthesis

Creator:: Dei Rossi, Dale Raymond
Abstract:: The Diels-Alder reaction represents a promising tool for use in asymmetric synthesis. The reaction involves a rigid transition state that facilitates the formation of one diastereomeric transition state and is reversible. This satisfies two necessary criteria for asymmetric synthesis. The Diels-Alder reactions of 1,l-dialkylspiro[2.4]-4,6- heptadienes with maleic anhydride and p-benzoquinone...

An approach toward the synthesis of euonyminol and cathedulin K- 19

Creator:: Shin, Hyunik
Abstract:: A synthetic approach toward the two major fragments of cathedulin K-19, euonyminol (4) and dimethyl cathate (69), was investigated. Synthesis of dimethyl cathate was accomplished in 3 steps starting from 73. Efforts directed towards the synthesis of euonyminol, a highly oxygenated dihydroagarofuran sesquiterpene, was advanced to a stage in which...

Fundamental Studies of the Structure-Property Correlations of Na-ion and K-ion Storage in Non-Graphitic Carbon

Creator:: Li, Zhifei
Abstract:: Grid-scale energy storage systems are urgently needed to increase the flexibility and rigidity of the grid for modern society and take full advantage of the renewable green energy resources such as solar energy and wind energy. Na-ion batteries (NIBs) and K-ion batteries (KIBs) have been emerged as one of the...
