Scientists Discover Cinnamon Compounds’ Potential Ability To Prevent Alzheimer’s

By

However, two compounds found in cinnamon –– cinnamaldehyde and epicatechin –– are showing some promise in the effort to fight the disease. According to George and Graves, the compounds have been shown to prevent the development of the filamentous “tangles” found in the brain cells that characterize Alzheimer’s. Responsible for the assembly of microtubules in a cell, a protein called tau plays a large role in the structure of the neurons, as well as their function. “The problem with tau in Alzheimer’s is that it starts aggregating,” said George, a graduate student researcher. When for the protein does not bind properly to the microtubules that form the cell’s structure, it has a tendency to clump together, she explained, forming insoluble fibers in the neuron. The older we get the more susceptible we are to these twists and tangles, Alzheimer’s patients develop them more often and in larger amounts. The use of cinnamaldehyde, the compound responsible for the bright, sweet smell of cinnamon, has proven effective in preventing the tau knots. By protecting tau from oxidative stress, the compound, an oil, could inhibit the protein’s aggregation. To do this, cinnamaldehyde binds to two residues of an amino acid called cysteine on the tau protein. The cysteine residues are vulnerable to modifications, a factor that contributes to the development of Alzheimer’s.
