The document provides a work plan for ESR10, a fellow working on the DECIDE project, which aims to develop more potent forms of Vitamin D3 that are extremely active against leukemia cells. Over three years, ESR10 will conduct chemistry to produce Vitamin D3 compounds, analyze their structures, test their binding and activity against leukemia cells, and select the most potent compound. The plan also includes training objectives for ESR10 to develop skills, participate in workshops, and receive supervision.
