Drug safety assessment of kaurene
1. Design of experiment
After 6-week-old male C57BL/6N mice were subjected to adaptive feeding for 1 week, the mice were randomly divided into 4 groups of 10 mice each, specifically into a normal control group (normal mice diet, abbreviated as ND), a low-dose kaurene group (normal mice diet containing 0.002% AGT by mass, abbreviated as AGT 0.002%), a medium-dose kaurene group (normal mice diet containing 0.02% AGT by mass, abbreviated as AGT 0.02%), and a high-dose kaurene group (normal mice diet containing 0.20% AGT by mass, abbreviated as AGT 0.20%). Male C57BL/6N mice respectively receive equal amounts of normal mouse daily ration and normal mouse daily ration mixed with 0.002%, 0.020% and 0.20% AGT respectively for 12 weeks, and then the levels of a mouse blood central muscle injury marker CK-MB, a liver injury marker ALT and a kidney injury marker Cr are detected, so that the safety of medicinal materials taking kaurene as an effective component for a long time is specifically studied.
2. Experimental results
After detecting that male C57BL/6N mice respectively receive equal amounts of daily ration of normal mice and daily ration of normal mice mixed with 0.002%, 0.020% and 0.20% AGT for 12 weeks, blood central muscle injury marker CK-MB, liver injury marker ALT and kidney injury marker Cr levels of the mice are shown in table 1 and figures 2-4.

As can be seen from tables 2, 3 and fig. 5 to 7, the mice in the medium dose group (hfd+agt 0.02%) and the high dose group (hfd+agt 0.20%) had significantly reduced body weight compared to the simple high fat group (HFD), wherein the high dose group (hfd+agt 0.20%) had a weight loss effect similar to that of Metformin hydrochloride treatment group (hfd+metaformin 0.25 g/kg) and were not significantly different. Compared with the simple high-fat group, the body fat content of the mice in the medium-dose group and the high-dose group is obviously reduced, which proves that the AGT has the effect of obviously reducing the weight rise and the obesity of the mice caused by high-fat diet.
(2) Each group of mice was subjected to Glucose Tolerance Test (GTT) after 6 hours on an empty stomach, and the glucose tolerance curve was measured, and the detection results are shown as a in fig. 8; the area under the curve (AUC) formed by blood glucose versus time was calculated for each group of mice as shown in table 4 and B in fig. 8; after mice were sacrificed at the end of the experiment, fasting blood glucose was measured, and the fasting blood glucose values of each group of mice are shown as C in table 4 and fig. 8.
TABLE 4 influence of kaurene on the area under the glucose tolerance curve and the fasting blood glucose values of high-fat diet mice
As can be seen from table 4 and fig. 8, ingestion of medium and high doses of AGT significantly improved glucose tolerance in mice compared to the simple high fat group (HFD), significantly reduced the area under the curve (AUC) formed by blood glucose versus time; the high fat diet significantly increased fasting blood glucose levels compared to the normal control group, which was effectively reversed by medium and high doses of AGT. The effect of reducing blood sugar and improving glucose tolerance of the high-dose group is equivalent to that of a metformin hydrochloride treatment group, which shows that kaurene has good effects of reducing blood sugar and improving insulin sensitivity.
(3) The results of measuring the total blood cholesterol, the blood low density lipoprotein cholesterol, the blood triglyceride and the blood free fatty acid level of each experimental group are shown in Table 5. Wherein, the detection result of the serum total cholesterol concentration of each experimental group of mice is shown in figure 9; the results of serum low density lipoprotein cholesterol concentration measurements for mice of each experimental group are shown in fig. 10; the results of serum triglyceride concentration detection of mice of each experimental group are shown in fig. 11; the results of the serum free fatty acid concentration measurements of the mice of each experimental group are shown in FIG. 12.
TABLE 5 influence of kaurene on serum lipid levels in high fat diet mice
As can be seen from table 5 and fig. 9-12, the high fat diet resulted in significantly elevated blood lipid levels in mice compared to the normal control group; intake of medium dose (hfd+agt 0.02%) and high dose (hfd+agt 0.20%) of AGT significantly reduced total TC and LDL in mice blood, and reduced blood TG and FFAs levels compared to the simple high fat group (HFD). The effect of cholesterol and triglyceride reducing effect of the high-dose group is similar to that of the metformin hydrochloride treatment group, which shows that kaurene can obviously reduce the hypercholesterolemia and hypertriglyceridemia of mice caused by high-fat diet.
(4) The liver lipid drop size of each group of mice was measured by hematoxylin-eosin (HE) staining method, the measurement results are shown in FIG. 13, wherein the scale in FIG. 13 is 100 μm; liver triglyceride levels for each group of mice are shown in table 6 and fig. 14; the liver cholesterol levels of each group of mice are shown in table 6 and fig. 15.
TABLE 6 influence of kaurene on liver lipid levels in high fat diet mice
As can be seen from table 6 and fig. 13-15, liver lipid deposition was aggravated in the single high fat group (HFD) mice compared to the normal control group (ND), liver TG and TC levels were significantly upregulated, whereas medium and high dose AGT significantly inhibited liver lipid deposition and TG and TC levels elevation in mice caused by the high fat diet, wherein the anti-non-alcoholic fatty liver effect of the high dose AGT was similar to that of the metformin hydrochloride treated group, demonstrating that kaurenin had the effect of significantly alleviating the non-alcoholic fatty liver in mice caused by the high fat diet.
(5) Test for verifying the expression level of Tight-junction protein in colon tissue of mice with increased Metabolic syndrome in each group of mice
The expression levels of the zonal Occidin and ZO-1 proteins in the colonic mucosa of the mice of each experimental group are shown in Table 7 and FIG. 16 and FIG. 17.
TABLE 7 expression levels of the zonal Occlutin and ZO-1 proteins in the colonic mucosa of mice of each experimental group
As can be seen from table 8, fig. 16 and fig. 17, the protein expression levels of ZO-1 and Occludin were significantly higher for both medium and high doses of AGT than for the model group, wherein the medium dose of AGT increased the expression levels of Occludin and ZO-1 proteins back to 1.05 and 0.96, respectively; the high dose of AGT raised the expression levels of Occludin and ZO-1 protein back to 0.98 and 1.10, respectively, indicating that kaurene has a good effect in maintaining the structural integrity of the colon barrier, and can be used for the treatment of intestinal injury diseases.
(6) The results of measuring the Lipopolysaccharide (LPS) content in the blood of mice of each experimental group are shown in Table 8 and FIG. 18.
TABLE 8 results of measurement of Lipopolysaccharide (LPS) content in blood of mice of each experimental group
As can be seen from table 8 and fig. 18, lipopolysaccharide in blood of mice of the simple high fat group (HFD) was significantly elevated compared to the normal control group (ND). Whereas medium and high doses of AGT significantly inhibited the increase in lipopolysaccharide content in the blood of mice caused by a high fat diet. The kaurene-bisapigenin has positive effect on lipopolysaccharide-induced inflammation, and can be used for improving enterogenic endotoxemia.
In conclusion, the medicine taking kaurene as the active ingredient has the effects of remarkably resisting obesity, resisting insulin resistance, reducing blood sugar, resisting hyperlipidemia and nonalcoholic fatty liver, improving intestinal injury diseases, improving enterogenic endotoxemia and the like and relieving metabolic syndrome.
Although the foregoing embodiments have been described in some, but not all, embodiments of the invention, it should be understood that other embodiments may be devised in accordance with the present embodiments without departing from the spirit and scope of the invention.
