Vanderbilt University researchers use curcumin analog to develop atomizer to treat Alzheimer’s

My question is:  If the analog works, then why not use the original curcumin molecule?  Because it is not patentable (dollars)?

Curcumin’s ability to fight Alzheimer’s studied

Vanderbilt investigators are studying curcumin, which is found in the spice turmeric, as a treatment for Alzheimer’s disease.

One of the most promising new treatments for Alzheimer’s disease may already be in your kitchen. Curcumin, a natural product found in the spice turmeric, has been used by many Asian cultures for centuries, and a new study indicates a close chemical analog of curcumin has properties that may make it useful as a treatment for the brain disease.

“Curcumin has demonstrated ability to enter the brain, bind and destroy the beta-amyloid plaques present in Alzheimer’s with reduced toxicity,” said Wellington Pham, Ph.D., assistant professor of Radiology and Radiological Sciences and Biomedical Engineering at Vanderbilt and senior author of the study, published recently in the Journal of Alzheimer’s Disease.

Accumulation and aggregation of protein fragments, known as beta-amyloid, drives the irreversible loss of neurons in Alzheimer’s disease.

Developing small molecules to reduce this accumulation or promote its demolition is crucial, but the ability of these small molecules to cross the blood-brain barrier has been a restricting factor for drug delivery into the brain.

Pham and colleagues at Shiga University of Medical Science in Otsu, Japan, developed a new strategy to deliver a molecule similar to curcumin more effectively to the brain.

“One of the difficulties in the treatment of Alzheimer’s disease is how to deliver drugs across the blood brain barrier,” he said. “Our body has designed this barrier to protect the brain from any toxic molecules that can cross into the brain and harm neurons.

“But it is also a natural barrier for molecules designed for disease-modifying therapy,” Pham said.

To work around the problems of giving the drug intravenously, the researchers decided to develop an atomizer to generate a curcumin aerosol. The Japanese researchers developed a molecule similar to curcumin, FMeC1, which was the one actually used in this study.
