(69) Experimental Animals:
(70) Male SD rats weighing 180-200 g were fed adaptively for 7 days. Based on body weight, 10 animals were used as control and the remaining animals were intragastrically administered with the lipid emulsion every day, 1 ml/100 g body weight for 14 days. After fasting for 12 hours, 1 mL of blood was collected from the orbits of the animals, and was determined by Hitachi Automatic Biochemical Analyzer 7080 for serum cholesterol (CHO), triglyceride (TG), low density lipoprotein (LDL-C) and high density lipoprotein (HDL-C).
(71) According to TC values, the animals, which were administrated with the lipid emulsion, were divided into Model group, Simvastatin group (Sim, 10 mg/kg), Obeticholic Acid group (10 mg/kg) and Compound 0122 groups (80 mg/kg). The modeled rats were continued with the intragastric administration of the lipid emulsion. At the same time, the pharmaceutical-administered groups were administrated with a corresponding dose of pharmaceuticals, while the Model group was administrated with an equal volume of solvent. The pharmaceutical-administered groups were administrated with the lipid emulsion in the morning, and with the pharmaceuticals in the afternoon. The animals were measured for the body weight once a week, and were observed. After 14 days of continuous administration, 1 mL of blood was collected from the orbits, and was determined for the contents of triglyceride, cholesterol, low density lipoprotein and high density lipoprotein in blood serum. It was shown by the experimental results that the blood lipid levels of the pharmaceutical-administered groups had no obvious change, and Obeticholic Acid had no blood lipid-reducing effect. The experimental results are shown in Table 1. The functions of liver and kidney were tested after 4 weeks and the results are shown in Table 2.

(77) Simple fatty liver has the following characteristics: more than 30% of hepatocytes in a low-power field have steatosis, but there are no other obvious histological changes, that is, no inflammation, necrosis and fibrosis. The one having, in the visual field, 30% to 50% of hepatocytes with steatosis has low-grade fatty liver; 50% to 75% of hepatocytes with steatosis would be mid-grade fatty liver; more than 75% of hepatocytes with steatosis would be severe fatty liver. The one having, in a low-power field, <30% of hepatocytes with steatosis is called fatty change of liver.
(78) The results in Table 3 show that the compounds can significantly reduce hepatic steatosis and the infiltration of inflammatory cells. Thus, it is demonstrated that Compounds 1-22 have significant therapeutic effect on fatty liver.
(79) 2. Experiments of Weight Loss
(80) 2.1 Therapeutic Effect on Nutritive Obesity C57 Mice
(81) Animals:
(82) C57 mice, male, 18-20 g of body weight. The mice were randomly divided into Control group, Model group, Orlistat group, Compound 13 group and Compound 14 group, with 6 mice in each group.
(83) Pharmaceuticals:
(84) appropriate amounts of orlistat, Compound 13 and Compound 14 were weighed respectively, added with 0.5% CMC-Na and grinded to dissolve.
(85) Experimental Process:
(86) The mice in Control group were fed with normal diet, and the other mice were fed with high-fat diet. All of the mice had free access to water. After one week of feeding, the pharmaceuticals were intragastrically administrated. The dose was 40 mg/kg body weight for orlistat, 80 mg/kg for Compounds 13 and 14. The body weight of the mice was weighed every week during the experiment which lasted for 28 days.
(87) The experimental results are shown in Table 4.
(88) TABLE-US-00004 TABLE 4 effect of tested compounds on body weight of mice in the experiment with nutritive obesity C57 mice (
(89) As shown by Table 4, Compounds 13 and 14 can significantly decrease the body weight of the mice from Day 14 as compared with Model group, and have better effect than Orlistat.
(90) 2.2 Experiment of the Weight Loss Effect of Tested Compounds on Ob/Ob Mice
(91) Animals:
(92) 36 ob/ob mice, male, 18-20 g of body weight, fed adaptively for one week before use. The mice were randomly divided into Control group, Model group, Orlistat group, Compound 13 group and Compound 14 group, with 6 mice in each group.
(93) Pharmaceuticals:
(94) appropriate amounts of orlistat, Compound 13 and Compound 14 were weighed respectively, added with 0.5% CMC-Na and grinded to dissolve.
(95) Experimental Process:
(96) After feeding for one week, the mice were intragastrically administrated with the pharmaceuticals except the mice of Control group. The dose was 40 mg/kg body weight for orlistat, 80 mg/kg for the other pharmaceuticals. The body weight of the mice was weighed every week during the experiment which lasted for 28 days.
(97) TABLE-US-00005 TABLE 5 Experiment of the weight loss effect of tested compounds on ob/ob mice (
(98) As shown by Table 5, Compounds 13 and 14 can significantly decrease the body weight of the ob/ob mice as compared with Model group, and have better effect than Orlistat.
(99) 3. Acute Toxicity Test
(100) A single oral-dose method was employed.
(101) Animals:
(102) ICR mice, 18-20 g of body weight, 20 mice in each group, half male and half female.
(103) Experimental Pharmaceuticals:
(104) Compound 01 (5 g/kg), Compound 02 (5 g/kg), Compound 08 (5 g/kg), Compound 09 (5 g/kg), Compound 12 (5 g/kg), Compound 13 (5 g/kg), compound 14 (5 g/kg), compound 18 (5 g/kg), compound 21 (5 g/kg), compound 22 (5 g/kg). The pharmaceuticals were added with 0.5% CMC-Na, ground and mixed well for reserve.
(105) Experimental Process:
(106) After fasting for 16 h, the animals were orally and intragastrically administrated with the tested pharmaceuticals in a single dose respectively. After administration, the mice were fasted for another 3-4 h. The general conditions of the animals were closely observed for 6 h after the administration, and further observed for 14 days.
(107) Experimental Results:
(108) No animal died during the experiment and no abnormal condition was observed.
(109) Acute toxicity: ID505 g/kg.
