Abstract
We have achieved the divergent total synthesis of nine isoflavone natural products 1-9 starting from commercially available 2,4,6-trihydroxyacetophenone as a starting material. The isoflavone skeleton of 1-9 was constructed by the Suzuki-Miyaura coupling reaction as the key reaction. Investigation of the potential of 1-9 as therapeutic agents for transthyretin (TTR) amyloidosis revealed that millexatin F (3) showed the best efficacy in ex vivo competitive binding experiments and thioflavin-T fluorescence studies. Therefore, millexatin F (3) is promising as a seed compound for a novel TTR amyloidosis therapeutic agent.
期刊介绍:
The Journal of Natural Products invites and publishes papers that make substantial and scholarly contributions to the area of natural products research. Contributions may relate to the chemistry and/or biochemistry of naturally occurring compounds or the biology of living systems from which they are obtained.
Specifically, there may be articles that describe secondary metabolites of microorganisms, including antibiotics and mycotoxins; physiologically active compounds from terrestrial and marine plants and animals; biochemical studies, including biosynthesis and microbiological transformations; fermentation and plant tissue culture; the isolation, structure elucidation, and chemical synthesis of novel compounds from nature; and the pharmacology of compounds of natural origin.
When new compounds are reported, manuscripts describing their biological activity are much preferred.
