Lowering The Cost And Raising The Efficiency Of A Cure To Chagas Disease, Madeleine Peters
Lowering The Cost And Raising The Efficiency Of A Cure To Chagas Disease, Madeleine Peters
Arkansas Women in STEM Conference
Chagas disease, classified as a neglected tropical disease (NTD), is caused by the parasite Trypanosoma cruzi and is an underfunded and under researched disease. The only FDA-approved drug in the United States is benznidazole which is expensive, harmful, and only effective in the illness’ acute phase. The goal is to create a more effective, lower costing and less harmful drug by using a condensation reaction to substitute different amines to diethyl squarate (DES) to make cycloalkylsquaramides. Both DES and the amines used are relatively low in price with a simple, efficient, and high yielding synthesis. Low synthetic cost and ability …

The synthesis of air-stable ligand-free nanopalladium hydride (PdNHx) in water was achieved and applied to various organic transformations, including (1) reduction of heteroaromatics such as (iso)quinolines, phenanthrolines, benzotriazole, and naphthyridines, (2) regio- and chemoselective reduction of nitroarenes, (3) alkyne reductions, (4) chemoselective dehalogenation, and (5) base-free detriflation. Both the synthesis of PdNHx and the reductions were carried out under mild conditions in a micellar medium using our designer surfactant PS-750-M, which eliminates the need for toxic organic solvents and extremely high hydrogen pressure and temperature. Notably, PS-750-M is also a replacement of hazardous polar-aprotic solvents. This newer approach for selective …
