Development Of A Chemical Genetic Screen To Identify Compounds That Enhance Laromustine Cytotoxicity, Xiaoou Wang

Honors Theses

Laromustine is a chemotherapeutic sulfonylhydrazine prodrug used in clinical trials against acute myeloid leukemia. Though laromustine showed some success in clinical trials, more experiments are needed to understand the hematological toxicity and the molecular mechanisms of patients’ resistance. This project aims to develop a strategy to identify compounds synergistic with laromustine in cultured leukemia cells from a library of 450 FDA-approved compounds through a forward chemical genetic screen. To optimize the screen, the cell seeding density, doubling time, and dose response curves were determined. The optimized concentration of HL60 cells in these experiments was determined to be between 25,000 and …
