• terrestrial plants, algae, and insect pheromones that purportedly have anticancer, antifungal, and antibiotic activity, among others. For example, parthenolide (6) has anti-inflammatory and anti-hyperalgesic effects and induces apoptosis of human acute myelogenous leukemia stem and progenitor cells [24

• structural features can be found in the cyclic framework of (9E)- and (9Z)-trisporic acid B ((9E)-3, (9Z)-3) and its methyl esters (9E)-4 and (9Z)-4, which are very potent fungal pheromones [16][17][18][19][20]. Both the 9E and the 9Z isomer occur naturally (Figure 1). Trisporic acids have been isolated from
