Description

Application of urolithin B amide derivatives
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.

Mu.M of urolithin B was improved by 9.43% compared to the control group and 71g,71k amide derivative was higher than that of negative control 11.54%,13.63%, respectively. The results of this example demonstrate the effect of 71g,71k amide derivatives having better resistance to heavy metals than urolithin B.
Example 5: urolithin B and amide derivatives improve learning ability of nematodes
Test drug: negative controls were formulated with 0.1% dmso.
The positive control urolithin B and its amide derivatives were dissolved in 0.1% dmso to prepare stock solutions.
Experimental method
Chemical trend ability measurement
The synchronized L4-phase nematodes are respectively exposed to an experimental group and a control group for 72 hours, 100mM NaCl culture medium is prepared for high-temperature and high-pressure sterilization, and the nematodes M9 are washed for 2-3 times to be starved and cultured in a new culture medium for 4 hours. Blank medium and culture with 100mM NaCl were drilled separately with a cork driller and based on overnight 14h in the test plate, chemotactic plates were formed and nematodes to be tested were transferred to the test plate, which is shown in FIG. 8 below: and drilling blank NGM and 100mM NaCl blank NGM at the position 0.5cm away from the two ends of the flat plate by using a cork driller to respectively make sample marks and comparison marks, so that the two-point marks and the center point form a straight line. Drawing two straight lines at the positions 2cm away from the center of the circle. 0.5mol/L NaN 3 was added before the test to turn the nematodes to a starting point, and after 1h the trend index (chemotaxis index) = (N A-NC)/N;NA =number of Nacl group nematodes, N C =number of control group nematodes, n=total number of nematodes) was determined.
Analysis of results
The learning ability of urolithin B and 71g,71k amide derivatives is shown in FIG. 6. As a result, the learning ability of the control group was 0.052, the learning ability of 20. Mu.M urolithin B was 0.32, and the learning ability of 71g,71k amide derivatives was 0.35,0.41. The results show that 20 mu M urolithin B and 71g,71k amide derivatives can significantly improve the learning ability of adult nematodes in the fourth day.
Example 6: influence of 20 mu M urolithin amide derivatives on growth status of E.coli
Test drug: negative controls were formulated with 0.1% dmso.
The positive control urolithin B and its amide derivatives were dissolved in 0.1% dmso to prepare stock solutions.
Experimental method
LB liquid medium after autoclaving was prepared as follows: 1. blank 2, addition of op50 3, addition of methoxy urolithin a and its 6, 7 amide derivatives 4, addition of op50 and methoxy urolithin a and its 6, 7 amide derivatives. Taking blank group as control, firstly measuring and adding oxyurolithin A and 6, 7 amide derivatives thereof, then placing the other two groups into a shaking table at 37 ℃ for 390min, measuring absorbance at OD595 of the other two groups every 30min, and recording and drawing an E.coli OD value growth curve.
Analysis of results
FIG. 7 shows the effect of 20. Mu.M methoxy urolithin A and 71g,71k amide derivatives on E.coli growth status. As shown in FIG. 7, the OP50 growth curve in LB liquid medium supplemented with 20. Mu.M urolithin B and 71g,71k amide derivatives thereof was similar to the OP50 growth curve in LB liquid medium not supplemented with the administration group, and the results of this example demonstrate that the life-prolonging effect of 20. Mu.M urolithin B and 71g,71k amide derivatives thereof was independent of the antimicrobial effect and the usability of foods.
