The number one stumbling block turned out to be synthetic organic chemistry. I was shocked because I thought the limiting factor was computational biology. So the NIH Roadmap really changed my view of the importance of chemistry and chemical engineering.” ~ Chemical & Engineering News July 3, 2006 35 ©2014 Gregory R Cook Monday, August 25, 14 Natural Products and Medicine • Paclitaxel (Taxol™): anticancer compound isolated from the bark of the pacific yew tree AcO PhCOHN O O H O cook.chem.ndsu.nodak.edu/chem240 OH OH HO O AcO PhOCO • Epibatidine: analgesic compound isolated from the skins of an ecuadorian tree frog Cl H N N 36 ©2014 Gregory R Cook Monday, August 25, 14
