*Abstract

Researchers at Nagoya University and Meijo University have synthesized a novel neurotrophic factor (NGF)-enhancing compound, which shows memory recovery effects on aged mice and senescence-accelerated mice (SAM). This compound is designed based on a steroid glycoside discovered from Okinawan Crown-of-Thorns Starfish. Researchers have found that the starfish-derived compound has NGF-enhancing (in vitro) and memory recovery effects (in vivo) and can pass through the blood-brain barrier. However, the quantity of starfish derived compound is very limited in nature. To solve this problem, researchers synthesized a compound (analog 1), which shows medicinal effects comparable to those of the natural steroid glycoside.

Title: Heterodimers and methods of using them
Usefulness: Heterodimers and methods of using them
Summary: For inhibiting cholinesterase e.g. acetylcholinesterase or butyrylcholinesterase and N-methyl-D-aspartate receptor; in the preparation of pharmaceutical composition for treating a disease or disorder of the nervous system in an animal (preferably human) i.e. neurodegenerative disease such as Alzheimer's disease, Parkinson's disease, Huntington's disease, stroke, epileptic fit, dementia, epilepsy, brain trauma, cognitive disorders (claimed), chronic pain, central nervous system disorders and ischemia.
Novelty: New heterodimers of tetrahydroacridines and tetrahydroquinolinones for treating neurodegenerative disease e.g. Alzheimer's disease, Parkinson's disease, Huntington's disease, stroke, dementia, epilepsy, brain trauma and cognitive disorders
