z-Octadecyl caffeate may have pain-relieving activity. Octadecyl caffeate and coptisonine can stimulate glucose uptake at 25 and 50 ug/mL. Octadecyl caffeate and octadecyl coumarate applied to the surface of susceptible varieties in laboratory bioassays r
Vestitol is a phytoalexin with insect feeding-deterrent activity, it has antioxidant, anti-inflammatory and antimicrobial activities, it can inhibit neutrophil migration at a dose of 10 mg/kg, and shows MICs ranging from 25-50 to 50-100 ug/mL and MBCs ranging from 25-50 to 50-100 ug/mL.Vestitol exerts a limited inhibitory effect on S. hermonthica germination, it can significantly inhibit seedling growth, it also contributes, at least in part, to the host's defence mechanism and acts as a chemical barrier against the intrusion of the parasite.
