Marrone: Sarmentine Analogs

Sarmentine analogs have been disclosed by Marrone as useful for controlling pests, weeds and phytopathogens such as bacteria, fungi and viruses. The three compounds below are preferred compounds of the analogs presented. N-(2E,4E-decadienoyl)pyrrolidine is also called sarmentine and was first separated from the fruit of Piper sarmentosum in 1987. Sarmentine is also used as a solubilizer in hydrophobic compounds in cosmetics and pharmaceuticals.

Sarmentine demonstrates excellent control of pigweed (Amaranthus retroflexus L.), barnyard grass (Echinochloa crusgalli L.), bindweed (Convolvulus arvensis L), crabgrass (Digitaria sanguinalis L), Sprangletop (Leptochloa fascicularis Lam.), Dandelion (Taraxacum, officinale F.) and Lambsquarters (Chenopodium album L.). No results are reported for the pesticidal or fungicidal activity for the sarmentine analogs.
