Scientists obtained substances that provide a breakthrough in the treatment of neurodegenerative pathologies.

Russian scientists have synthesized chemical compounds that can stop the degeneration of neurons in Alzheimer’s, Parkinson’s, and other severe brain pathologies. These substances can provide a breakthrough in the treatment of neurodegenerative pathologies.

New molecules of pyrrolyl- and indolylazine classes activate intracellular mechanisms to combat one of the main causes of “aged” brain diseases – an excess of so-called amyloid structures that accumulate in the human brain with age. The essence of the study was published in the European Journal of Medicinal Chemistry. Experts from the Institute of Cytology of the Russian Academy of Sciences, the Institute of Organic Synthesis of the Ural Branch of the Russian Academy of Sciences, and the Ural Federal University (UrFU) took part in the study.

“Our compounds activate the synthesis of specific heat shock proteins and cause their accumulation in the cell,” said research co-author, professor of the Department of Organic and Biomolecular Chemistry at UrFU Irina Utepova. “Proteins of this type make it possible to protect neuronal tissue from an excess of toxic amyloids and to protect cells from various types of stress, including proteotoxic stress characteristic of neurodegenerative diseases.”

Important advantages of compounds from the series of pyrrolyl- and indolylazine classes are a profitable synthesis technology and low toxicity.

The obtained compounds were tested in cellular models of Alzheimer’s disease and secondary injuries after traumatic brain injury. In both cases, the new substances demonstrated a significant therapeutic effect, increasing the survival of neuronal cells. The most effective compound has been tested in living tissues of rats with secondary injuries after traumatic brain injury.

According to scientists, the use of pyrrolylazine in rehabilitation therapy allowed the animals to avoid the appearance of movement disorders and degeneration of hippocampal neurons. The research team has continued to study the mechanism of action of new compounds and is preparing for their preclinical testing.


Alzheimer’s and Parkinson’s diseases are diseases of the brain, in which the gradual degeneration of neurons leads to loss of speech, memory, and thinking. Most often they affect people over 65 years old. The global number of people suffering from Alzheimer’s disease alone in 2010 was estimated at 35.6 million. By 2050, growth is projected to be 115.4 million. Effective drugs for the prevention and treatment of ailments of this type have not yet been created. Existing remedies are aimed only at suppressing symptoms, but cannot stop the process of neurodegeneration itself.

  1. Thanks but how to remove this toxic Amyloidosis naturally in our body ?

  2. I am 88 years old and was just diagnosed with Parkinson’s. I have no clue about it but I do have a wonderful physician taking care of my future medications. Mine came on with double vision which only lasted a couple of hours and glad I went straight to the clinic because of the scare factor. This article that was sent to me and would like more information to give to my doctor.

    My mom is 90 and has dementia. From my guess, it started coming in about 3 years ago and has started to affect her speech. Would be most interested in participating in human clinical trials of this compound whenever they reach that point, hopefully soon.

  4. Nothing beats an active life, regular sleep cycles and an healthy diet. Vitamin supplements are also important specially if you have vit. deficiency.

  5. How can we now start to remove these toxins from our bodies now this is very informative but, if its something we can do now let us this disease is so sad to watch your love ones go through with dementia.

  6. Let Sleepy Joe give it a whirl

  7. This comment is a response to Claire’s stupid comment: take your comment and shove it where the sun don’t shine.

  8. I second that – Claire’s comment has no place here. Go hang out on the rwnj sites.
