Ungeremine

Ungeremine is a betaine-type alkaloid isolated from Nerine bowdenii[1] and related plants such as Pancratium maritimum.[2] Pharmacologically, it is of interest as an acetylcholinesterase inhibitor and accordingly as possibly relevant to Alzheimer's disease.[3] It also has been investigated as a bactericide.[2]
