EXAMPLE 2 pharmacological part
1. Experimental method
1.1 in vitro cell experiment screening method
Human normal liver cell (L02) strain, taking L02 cells with good growth state and in exponential growth phase, inoculating into 96-well plate at a certain concentration, culturing in RPMI1640 medium containing 10% fetal bovine serum and 1% penicillin/1% streptomycin, and culturing in incubator with 5% carbon dioxide at 37deg.C. After the cells are fused to 80%, the culture medium is changed into 2% fetal bovine serum and 25mol/L lithocholic acid (LCA) to stimulate the cells for 24 hours, so as to prepare a hepatocyte insulin resistance model; subsequently, treatments with different caffeic acid derivatives, compounds CP 1-CP 32 (10 or 100. Mu. Mol/L), were applied, a Control group (Control) and Model group (Model) were set, each group was set with 10 duplicate wells, and incubated for 24h. The liquid in the wells was then aspirated, washed 2 times with PBS buffer, cells were treated with 100mol/L2-NBDG containing 110-7mol/L insulin and incubated at 37℃for 30min, and the effect of the compound on glucose absorption by insulin stimulation was evaluated by changes in intracellular fluorescence intensity as detected at a full-automatic microplate reader excitation/emission wavelength (Ex/Em) of 488nm/520nm, and active compounds that improved LCA-induced insulin resistance-promoting glucose absorption were screened.
1.2 in vivo hypoglycemic Effect verification of active Compounds
After 50 male C57BL/6J mice of 6 weeks of age were fed for one week in a control group (CON, 10, standard diet Cat#D 12492) and a high fat diet group (40, high fat diet Cat#D1245 OJ) were fed for 6 weeks, and the high fat diet group was divided into 4 groups according to fasting blood glucose components: model group (HFD, high fat diet), caffeic acid group (CA, hfd+100mg/kg CA), active compound group (CP 11, hfd+100mg/kg CP 11), positive drug rosiglitazone group (ros., hfd+25mg/kg ros.), 10 groups each, 6 weeks of treatment. Body weight was measured weekly during animal feeding. OGTT and ITT experiments were performed at weeks 7 and 8 of the administration treatment for 12 hours and 4 hours, respectively, and intraperitoneal injection of 2g/kg glucose and 0.75U/kg insulin was performed, respectively, and tail vein blood sampling was performed for blood glucose for 0min, 30min, 60min, 90min and 120 min. The medicine is administrated by stomach irrigation, once a day for 9 weeks, fasted for 12 hours, anesthetized and blood taken, and is used for later biochemical index detection.
2. Experimental results
2.1 in vitro insulin resistance cell model screening Compounds for improving insulin resistance hypoglycemic action
The cell glucose uptake experimental result shows that the CP series compounds can improve cell insulin resistance and promote glucose absorption screening. Some derivatives can significantly improve LCA-induced L02 cell insulin resistance and significantly increase cellular glucose uptake. As shown in FIG. 1, compounds CP9 and CP14 significantly increased cellular glucose uptake when insulin resistant cells were treated at a concentration of 10. Mu. Mol/L for 24 hours; compounds CP7, CP10, CP11 and CP13 significantly increased cellular glucose uptake at concentrations of 10 and 100. Mu. Mol/L for 24 hours, with the compounds CP11 and CP13 having the most significant effects indicating that compounds CP11 and CP13 may have the effect of improving insulin resistance and treating type 2 diabetes.
In fig. 1, p <0.05 compared to control, p <0.01 compared to control, p <0.001 compared to control; * P <0.0001 compared to control group; p <0.05, # p <0.01 compared to model group, # p <0.001 compared to model group, # p <0.0001 compared to model group.
2.2 Effect of active Compound CP11 on body weight of high fat diet mice
As a result, as shown in fig. 2, the body weight of the mice in the control group, the model group and each of the administration groups increased gradually with the increase of the week old, and the body weight of the mice in the high-fat diet model group (HFD group) was significantly higher than that in the control group after receiving the high-fat diet for 9 weeks, and had a significant difference; high fat diet mice received drug treatment from week 6 (CA, CP11 and ros.), caffeic acid CA group, mice weighing comparable to HFD group; after 4 weeks of treatment of mice, the mice began to significantly increase in weight compared to HFD group, indicating that ros had the effect of increasing the weight of mice; whereas the body weight of the mice in the CP11 group was significantly lower than that of the HFD group after 5 weeks of treatment with CP11, indicating that CP11 significantly inhibited the weight gain of the mice caused by the high fat diet.
In fig. 2, p <0.05 compared to Control (CON); # compares p <0.05 to high fat diet group (HFD), # compares p <0.01 to HFD.
2.3 Effect of active Compound CP11 on high fat diet-induced hyperglycemia and insulin sensitivity in mice
As shown in a, B in fig. 3, the HFD group mice exhibited a significant glucose intolerance compared to the control group mice, and the glucose intolerance of the drug-interfered group mice was significantly improved compared to the HFD group; and CP11 mice exhibited better glucose tolerance than CA-combined ros. As shown in fig. 3c, d, the mice in the HFD group showed a slow and low blood glucose decrease after insulin injection compared to the mice in the control group, indicating that the mice developed significant insulin resistance; whereas insulin resistance was significantly improved in mice from the drug-interfered group compared to the HFD group.
In fig. 3, p <0.05 compared to Control (CON), p <0.01 compared to Control (CON), p <0.001 compared to CON, and p <0.0001 compared to CON; p <0.05, # compared to high fat diet group (HFD), p <0.01, # compared to HFD, p <0.001, # compared to HFD; +CA <0.05 compared to CP11, +CP11 <0.05 compared to Ros.
Consistent with this result, as shown in fig. 4, the serum of the mice in the CP11 and ros treatment groups had significantly reduced content of glycated serum protein compared to the HFD group, indicating that CP11 was effective in controlling the increase in blood glucose in high-fat diet mice and improving impaired fasting blood glucose in mice, and had excellent hypoglycemic effect. In addition, the serum of mice in the drug-treated group had significantly lower insulin content than that in the HFD group, wherein the decrease in insulin content was most pronounced in the CP11 treated group, and the insulin resistance index was significantly decreased and the insulin sensitivity index was significantly increased in the mice, indicating that the insulin sensitivity of the mice was significantly increased following drug intervention, particularly after CP11 treatment.
In fig. 4, p <0.0001, # p <0.05 compared to HFD, # p <0.01 compared to HFD, # p <0.001 compared to HFD, # p <0.0001 compared to HFD.
Conclusion:
the above in vivo and in vitro experimental results show that the CP11 compound can well improve the high-fat diet induced insulin resistance of mice, increase the insulin sensitivity of the mice, and well treat and control hyperglycemia caused by the high-fat diet, and the treatment effect is remarkable and slightly better than that of a positive drug ros (rosiglitazone), and most importantly: CP11 can also inhibit the weight gain of mice caused by high-fat diet effectively, and Ros can not inhibit the weight gain of mice caused by high-fat diet, but can obviously increase the weight of mice, so that the CP11 has the dual effects of reducing blood sugar and inhibiting weight gain, and has application prospect in treating obesity or high-fat diet-induced type 2 diabetes and obesity.
