  1. Introduction to Natural Products • Terpenes • Alkaloids • Pheromones • Antibiotics

  2. Terpenes • When we discuss the terpenes we are most interested in the carbon skeleton.

  3. Introduction to Natural Products Isoprene

  20. Non-Isoprenoid Terpenes

  21. Alkaloids Nitrogen containing, basic natural products often have powerful biological activity alkaloids are not as conveniently organized by some common structural component.

  22. Examples of alkaloids

  23. Antiobiotics There are many classes of antibiotics; four are listed as major groups: b-lactams ( includes the penicillins); tetracyclines (tetracycline); macrolides (erythromycin) and peptides (gramacidin). For the purposes of this course, we will be primarily concerned with macrolide antibiotics and highly-oxygenated compounds.

  24. Practice Problem #1 • For each of the example terpenes given to you, find the isoprene units that are contained in the carbon skeleta.
