“…potential Alzheimer’s drug works by reducing the rate of aging at the molecular level, according to a new study led by Salk Institute scientists.

.

The study explains how the drug both improves cognition and reduces the rate of aging, when given to very old mice.

.

Study authors say a drug that inhibits aging may succeed where drugs specifically aimed at Alzheimer’s have failed.

.

Getting the drug into human clinical trials will require a little over $1 million.”

 The study was published in the journal Aging Cell….

The mitochondrial ATP synthase is a shared drug target for aging and dementia

….“This really glues together everything we know about J147 in terms of the link between aging and Alzheimer’s,” says Dave Schubert, head of Salk’s Cellular Neurobiology Laboratory and the senior author on the new paper. “Finding the target of J147 was also absolutely critical in terms of moving forward with clinical trials.”

.

Schubert’s group developed J147 in 2011, after screening for compounds from plants with an ability to reverse the cellular and molecular signs of aging in the brain. J147 is a modified version of a molecule (curcumin) found in the curry spice turmeric. In the years since, the researchers have shown that the compound reverses memory deficits, potentiates the production of new brain cells, and slows or reverses Alzheimer’s progression in mice. However, they didn’t know how J147 worked at the molecular level.

.

In the new work, led by Schubert and Salk Research Associate Josh Goldberg, the team used several approaches to home in on what J147 is doing. They identified the molecular target of J147 as a mitochondrial protein called ATP synthase that helps generate ATP—the cell’s energy currency—within mitochondria. They showed that by manipulating its activity, they could protect neuronal cells from multiple toxicities associated with the aging brain. Moreover, ATP synthase has already been shown to control aging in C. elegans worms and flies.

.

“We know that age is the single greatest contributing factor to Alzheimer’s, so it is not surprising that we found a drug target that’s also been implicated in aging,” says Goldberg, the paper’s first author.

.

Further experiments revealed that modulating activity of ATP synthase with J147 changes the levels of a number of other molecules—including levels of ATP itself—and leads to healthier, more stable mitochondria throughout aging and in disease.

.

“I was very surprised when we started doing experiments with how big of an effect we saw,” says Schubert. “We can give this to old mice and it really elicits profound changes to make these mice look younger at a cellular and molecular level.”

.

The results, the researchers say, are not only encouraging for moving the drug forward as an Alzheimer’s treatment, but also suggest that J147 may be useful in other age-associated diseases as well.

.

“People have always thought that you need separate drugs for Alzheimer’s, Parkinson’s and stroke” says Schubert. “But it may be that by targeting aging we can treat or slow down many pathological conditions that are old-age-associated.”

Metformin

.

From WebMD, March 29, 2017:

.

“Doctors have prescribed metformin, the most common drug to treat type 2 diabetes, for about 60 years. But it’s received new attention as a possible anti-aging drug after researchers in Britain found that people with diabetes who took it outlived some of their peers who did not have the disease by 15%.

.

“They compared them to a whole bunch of people who were matched for weight and smoking and [other factors] but who didn’t have diabetes,” says Steven Austad, PhD, chairman of the biology department at the University of Alabama at Birmingham. “It turned out the diabetics on metformin were living longer than the non-diabetics who were not on metformin. … It was very, very intriguing.”

.

Austad is a bio-gerontologist and scientific director of the American Federation for Aging Research….

.

Scientists believe the drug works in the mitochondria, the powerhouses in the body’s cells that convert sugars like glucose into energy. Austad says metformin makes those powerhouses run more efficiently, reducing the release of substances known as free radicals. Free radicals can damage cells, hurting their ability to reproduce and causing defects.”

.

….Resveratrol, a compound found in grapes and nuts, may reduce stress that leads to cell aging. Research shows it can extend life span in yeast, worms, and fish, but these effects haven’t been demonstrated in humans yet.”

CurcuVIVA reduces joint pain, helps Alzheimers – Oxycodone use much lower


.

.

Rheumatoid arthritis pain is much better in a 54 year old female. She had half the month’s supply of oxycodone left at end of month for breakthrough pain – a big surprise! She had begun CurcuVIVA one daily for that month. It is a dietary supplement available without prescription.

.

PJ’s Prescription Shoppe carries it to make it easier for patients though it is available elsewhere.

.

CurcuVIVA is a capsule taken once daily. You will see the name Longvida on its label and in the literature. It is the same thing.

.

It is curcumin, the active ingredient in turmeric. It differs from turmeric because this form does cross the blood brain barrier to reach brain. Turmeric does not reach the brain, therefore turmeric has no effect on Alzheimers Disease or tauopathies (accumulation of tau proteins). Tau in Alzheimers Disease and frontotemporal dementia and parkinsonism has been linked to chromosome 17.

.

UCLA Alzheimers research unit developed this form of curcumin under the direction of Sally A. Frautschy and Greg Cole. On December 2012 they published in the Journal of Biological Chemistry showing Curcumin corrects molecular, synaptic and behavioral deficits in aged human tau transgenic mice.

 .

For more information on other actions of curcumin such as pain, etc, see a detailed review on the website of Memorial Sloan Kettering Cancer Center Herbs and Botanicals. I link to them on my website (bottom right column) as it is difficult to find. Curcumin has antiplatelet properties that may increase risk of bleeding. I recommend reading the details of mechanism of action and drug interactions.

.

Do not combine with other over-the-counter pain medications without checking this link for interactions.

.

It “exhibits neuroprotective, choleretic, anti-inflammatory, immunomodulatory, anti-proliferative and chemopreventive effects.” It was “found to be safe and equally effective as a non-steroidal anti-inflammatory drug for the treatment of osteoarthritis of the knee.”

.

Caution: “Patients with gastrointestinal disorders or predisposed to kidney stone formation should…use this supplement with caution.”

.

Contraindications: “Patients with bile duct obstruction, gallstones, and GI disorders including stomach ulcers and hyperacidity disorders should not take this supplement.”
