ABSTRACT
Humans have always relied on natural products and have continually explored their application to improving various aspects of our lives. Thus, we have sought to use natural products such as spices, avoring agents, perfumes, cosmetics, and dyes to control and overcome diseases. Some were recognized as poisons and others were used as insecticides and pesticides. This interest in, and fascination with, natural products continues today and, despite the fact that periodic claims pronounce that the era of natural products chemistry is over, this area of research is still attracting considerable interest and offering signicant promise. A recent review on the topic begins with the adage, “There’s life in the old dog yet!” and, according to the authors, this also holds true for natural product research.1
