Microbial transformations of galanthamin-precursors

Applied Microbiology and Biotechnology, 1986
Galanthamin is a medical important alkaloid. Its chemical synthesis gives a racemic product in low yields. Starting with a belladinderivative an enzymatic ring closure should lead exclusively to a chiral product possibly with the native structure. Although this reactions type is unknown in preparative biotransformations a large number of microorganisms

Facile synthesis of (±)‐, (+)‐, and (‐)‐galanthamine

Journal of Heterocyclic Chemistry, 1995
AbstractThe Amarylidacea alkaloid galanthamine (1a) is an acetylcholinesterase inhibitor that has been evaluated as a potential agent for the treatment of Alzheimer's disease. We report a very efficent synthesis of (±)‐galanthamine [(±)‐1a] from readily available isovanillin and tyramine.

Galanthamine in Alzheimer’s Disease

1994
Substantial efforts have been made in neurobiology and molecular biology but we are still far from a causal therapy of Alzheimer’s disease (AD). In the interim, and perhaps ultimately as an adjunct to a progression inhibitor which may not be absolute, symptomatic treatment has to be optimized. Tacrine’s approval by the FDA has stimulated a search for a

Daffodil production for galanthamine

Galanthamine is a bioactive that has proven effect to reduce the effect of Alzheimer's. A source of natural galanthamine is from daffodils, but only certain varieties grown under specific conditions produce enough galanthamine to make it economically viable to extract for commercial purposes.
