Abstract
The invention provides application of urolithin B amide derivatives, and belongs to the field of medicines. The urolithin B amide derivatives can be used for preventing or treating neurological diseases related to mitochondrial activity reduction, including aging and neurodegenerative diseases, and the invention adopts caenorhabditis elegans as a model, and test results show that 20 mu M of urolithin B and N- (cyclohexylmethyl) -2- (6-oxo-6H-benzo [ c ] benzopyran-3-yl) oxy) acetamide and 2- ((6-oxo-6H-benzo [ c ] benzopyran-3-yl) oxy) -N- (pyrazin-2-ylmethyl) acetamide have the effects of prolonging the service life of the caenorhabditis elegans and enhancing the cognitive ability or relieving cognitive dysfunction. The invention discloses an application of an amide derivative of urolithin B in resisting aging and preventing neurodegenerative diseases.
Description
Technical Field
The invention belongs to the field of medicines, and particularly relates to application of a urolithin B amide derivative in preparation of a medicine for preventing organism aging.
Background
Alzheimer's Disease (AD) is the most common neurological disorder associated with cognitive decline, and AD is a neurodegenerative disorder in which the degree of dementia gradually worsens with aging of the human body's age.
The aging of the organism is essentially related to the autophagy dysfunction of mitochondria, the instability of genome, the shortening of telomerase, the imbalance of protein homeostasis and the degradation of cell viability. Since the mechanism of AD formation is unknown, the deposition of senile plaques pushes to aβ (amyloid β), and the formation of amyloid β has numerous possible causes. At most, the current test drugs such as cholesterol inhibitors, cholinesterase inhibitors and the like used for preventing the Alzheimer's disease caused by aging clinically only can prevent the disease from deteriorating, and no drugs and methods for completely treating the disease exist. Because the etiology of AD is not yet clear, research is also lacking in better animal models. The caenorhabditis elegans (Caenorhabditis elegans, C.elegans) is taken as a model organism, only 3 days is needed for the development of the caenorhabditis elegans from eggs to adults under the condition of rich nutrition at 20 ℃, the genes of the caenorhabditis elegans and related genes of human beings have high conservation of 60-80%, and experimental results play an important role in prompting the anti-aging effect of the human beings; because the growth period of the nematodes is short, a large amount of sample amount nematodes can be used for experiments in a short period, and the experimental results are reliable; in the research of neurodegenerative diseases, the nematode can easily obtain an ideal disease defect type system model, has transparent body, is easy to observe and detect phenotypic characteristics, has complete nerves, movements and reproductive systems, and the interaction among cells enables the nematode to form rich movement behaviors such as advancing, retreating, group chemotaxis and the like, so that the nematode can be easily operated in genetics and pharmacology in the model research of related diseases, and has important significance for preventing and exploring pathogenesis and treatment methods of the neurodegenerative diseases.
Ellagitannins (ELLAGITANNIN) are polyhydric phenolic compounds currently found in certain fruits, nuts and plants, and belong to the class of hydrolysable tannins which are metabolized by the human intestinal flora into more readily absorbable uroliths, a process in which ellagic acid loses a lactone ring and gradually removes hydroxyl groups. The ellagic acid loses lactone ring to obtain urolithin M5, and the urolithin M5 is dehydroxylated at different positions to obtain monohydroxy urolithin B. Patent number CN 113387916 discloses a process for the preparation of urolithin B and amidated derivatives. If a novel urolithin inhibitor is found to be effective in improving cognitive function, or improving cognitive ability, or even treating cognitive impairment, it would make a valuable contribution to the anti-aging field.
