3. Results of the experiment
3.1 high fat mouse model index detection
In order to examine whether the high-fat mouse model is successfully established, 5 mice are randomly extracted from a normal feed group and a high-fat feed group respectively, and glucose, triglyceride, aspartate aminotransferase, total cholesterol and high-density lipoprotein cholesterol in the plasma of the mice are detected, and the detection results are shown in a figure 1 and a table 1.
TABLE 1 detection of Biochemical indicators related to high fat model mice
As can be seen from fig. 1 and table 1, the plasma glucose, triglyceride, aspartate aminotransferase, total cholesterol, and high-density lipoprotein cholesterol of the mice in the high-fat diet group are all significantly increased, which indicates that the establishment of the high-fat mouse model is successful.
Evaluation of blood lipid-lowering Effect of 3.21-phenyl-1-propanol
In order to examine the effect of 1-phenyl-1-propanol on blood fat, the influence of 1-phenyl-1-propanol on the content of triglyceride in the plasma of an obese model mouse after the obese model mouse is established by feeding a mouse high-fat feed is examined, and the detection result is shown in a figure 2 and a table 2.
TABLE 2 plasma triglyceride, glucose, aspartate aminotransferase levels and statistical differences in the treatment groups
As can be seen from FIG. 2 and Table 2, the plasma triglyceride level of the mice in the drug group was very significantly reduced, indicating that 1-phenyl-1-propanol had the effect of reducing the blood lipid level of the mice with a high-fat diet.
Evaluation of hypoglycemic Effect of 31-phenyl-1-propanol
To examine the effect of 1-phenyl-1-propanol on blood lipids, the effect of each treatment on glucose in mouse plasma was examined, and the results are shown in FIG. 2 and Table 2.
As can be seen from FIG. 2 and Table 2, the plasma glucose content of the mice in the drug group is significantly reduced compared with that in the control group, which indicates that the 1-phenyl-1-propanol has a relieving effect on the hyperglycemia of the mice caused by high-fat diet, and can be used for solving the hyperglycemia complications existing in nutritional obese patients and treating diabetes.
Effect of 41-phenyl-1-propanol on aspartate aminotransferase
To examine the effect of 1-phenyl-1-propanol on blood lipids, the effect of each treatment on aspartate aminotransferase in the plasma of mice was examined, and the results are shown in FIG. 2 and Table 2.
As can be seen from FIG. 2 and Table 2, the aspartate aminotransferase was significantly reduced in the drug group mice. In clinical manifestations, obese patients not only have a large amount of subcutaneous fat accumulated, but also may have a large amount of fat accumulated around their internal organs, and the excessively accumulated fat may interfere with the normal function of the visceral cells, for example, the liver, and the fat excessively accumulated around the liver may cause the occurrence of fatty liver, and further cause a certain degree of damage to the liver cells, and finally, the content of aspartate aminotransferase in the blood is increased. The reduction of aspartate aminotransferase in the drug group mice is associated with the alleviation of liver damage caused by fat accumulation, indicating that 1-phenyl-1-propanol has a potential protective function for the liver.
Effect of 3.51-phenyl-1-propanol on the content of bile acids of various species
The bile acid has many different types and combination forms, the affinity of different bile acids to different receptors is different, the effect is different, in order to observe the influence of 1-phenyl-1-propanol on the composition of bile acid in the plasma of the mouse, the LC-MS method is adopted in the experiment to separate and measure different types of bile acid in the plasma sample of the mouse, and the concentration change of different types of bile acid is observed. The concentration of 36 different bile acids was determined in this experiment, and the results are shown in FIG. 2.
From the results of fig. 3, it can be seen that: free primary bile acids in plasma: cholic Acid (CA), chenodeoxycholic acid (CDCA) and alpha/beta-murine cholic acid (alpha/beta-MCA) have no obvious change, and the results of the change of the contents of cholesterol and total bile acid in figure 4 show that 1-phenyl-1-propanol has little influence on the direction and the pathway of primary bile acid generated by cholesterol. In secondary bile acids, LCA exists mainly in free form, and a small amount of LCA circulating to the liver undergoes sulfocoupling at the 3-hydroxyl position by sulfotransferase (SULT2a1) and is rapidly secreted into bile, while most of LCA is excreted without being reabsorbed. Therefore, the plasma levels of LCA were very low, which may be the reason why LCA could not be detected in this test; other secondary bile acids, such as: the content of DCA and HDCA has no obvious change, which shows that 1-phenyl-1-propanol has little influence on the catalytic 7 alpha-dehydroxylation of the bacterial flora in the intestinal tract, and 1-phenyl-1-propanol has no obvious influence on the environment of the intestinal flora of mice. In summary, 1-phenyl-1-propanol had no significant effect on the metabolic pathways by which cholesterol generates bile acids and the conversion of primary bile acids to secondary bile acids.
Of the conjugated bile acids present in plasma, 4% are present in glycine-conjugated form and 9% are present in taurine form. As can be seen from FIG. 3, the plasma levels of glycine-binding bile acids were significantly increased in the mice administered with the agent. The number of glycine-binding bile acids tested at this time was 8. Among these, 5 conjugated bile acids, which were significantly increased statistically, were removed, namely: GHDCA, GUDCA, GCDCA, GDHCA, lambda-GMCA; the remaining three, namely: plasma contents of GLCA (p is 0.051), GDCA (p is 0.104) and GCA (p is 0.665) are all higher than those of a control group; in the taurine-conjugated bile acid of the mice of the administration group and the mice of the control group, the content of the primary bile acid and the content of the secondary bile acid are not obviously changed. The 1-phenyl-1-propanol has specific promotion effect on the generation and secretion of glycine-conjugated bile acid, and further plays roles in reducing blood fat and blood sugar.
The results of the above examples show that 1-phenyl-1-propanol can simultaneously lower the efficacy of triglycerides and blood glucose in the plasma of mice on a high-fat diet; meanwhile, the concentration of aspartate aminotransferase in the plasma of a high-fat diet mouse can be reduced, and the liver protection function is potential; the 1-phenyl-1-propanol has no obvious influence on the metabolic pathways of generating bile acid by cholesterol and converting primary bile acid into secondary bile acid, and the effects of reducing blood fat and blood sugar are achieved mainly by specifically increasing the content of glycine-conjugated bile acid in plasma. The medicament for treating hyperlipidemia and diabetes mellitus prepared from 1-phenyl-1-propanol provided by the invention has good effects of reducing blood fat and blood sugar, has small toxic and side effects on liver, does not cause adverse reaction, and is suitable for treating hyperlipidemia and complications thereof caused by high-fat diet.
