Was Elion's work reliant on trial and error?
While there's always an element of experimentation in science, my method was deliberately designed to minimize pure trial and error. The traditional approach was often akin to searching for a needle in a haystack. My colleagues and I aimed to narrow down the search considerably. We would start with a known biochemical pathway that was vital for a disease process and then rationally design molecules that would interfere with that specific step. For instance, with 6-mercaptopurine for leukemia, we targeted purine synthesis. It required synthesizing and testing many compounds, yes, but each compound was designed based on a hypothesis derived from biochemical understanding, not just random screening. It was about being prepared when an idea showed promise.
