Florence Nzaniye, a senior at De La Salle North Catholic, spent last summer working with Sister Angela Hoffman, a biochemistry professor and research scientist at the University of Portland, after being awarded an American Chemical Society research grant for the 2012 summer.

While Sister Hoffman was the guide, it was up to Nzaniye to research, design, conduct and monitor the experiments for her experimental question.   

Nzaniye’s research focused on a specific species of Japanese Yew tree called “drupacea.” Her question was whether chemical compounds found in drupacea would have medicinal properties and maybe even be effective in treating cancer or malaria.

The research required the isolation of the compounds of interest in the plant through methods like chromatography to determine the general type of compounds.
She then tested the different compounds to see which ones would kill different bacteria and fungi. Compounds that could kill the bacteria and fungi where then sent to laboratories at OHSU to test their efficacy against a cancer cell line. Her findings were presented at an ACS event in November 2012.

Sister Hoffman hopes to have another De La Salle student continue this research next summer.
