产品描述 | Octreotide Acetate (Sandostatin) is a potent, long-acting synthetic somatostatin octapeptide analog that inhibits secretion of growth hormone. |
体内活性 | Octreotide处理组与盐水组相比,肿瘤体积显著减少。Octreotide-PPSG(1.4 mg/kg,i.p.)的抗肿瘤效果超过Octreotide-soln(100 μg/kg,i.p.)。Octreotide处理在原发性HCC携带大鼠中显著抑制SSTR2和SSTR5的表达水平,与盐水组相比。Octreotide-PPSG对SSTR2和SSTR5的表达抑制作用大于Octreotide-soln处理组。 Octreotide Acetate 盐试验剂量在2小时内将血清胃泌素水平显著降低至基线的约三分之一,效果持续约6小时。第21天,开始使用持续释放配方的 Octreotide Acetate 盐(5 mg肌内注射,每4周一次)。 |
动物实验 | Octreotide (acetate) is formulated in saline.MiceThirty mice with HCC xenografts are randomLy divided into three groups: (A) Octreotide-soln group, (B) Octreotide-PPSG group, and (C) control group. Octreotide-soln group receives i.p. injection of 100 μg/kg octreotide-soln once a day and totally for consecutive 14 days. Octreotide-PPSG group receives a single subcutaneous injection of 1.4 mg/kg Octreotide-PPSG, and the injection volume is about 0.2 mL. Control group receives i.p. injection of saline once a day for consecutive 14 days. Treatment starts on the next day after injection of H22 hepatoma cell suspension and maintains for 14 days. Tumor growth is monitored by periodic caliper measurements on day 7 and day 14 post seeding. Tumor volumes (V) are calculated based on the length and width of tumor by Eq. RatTwelve male SD rats are divided into two groups, and housed in standard cages at 25°C, with free access to food and water for a week prior to the experiment. Rats are subcutaneously injected with Octreotidereotide solution (Octreotide-soln) or Octreotide-PPSG at an equivalent single dose of 20 mg/kg. The dose is determined based on the clinical dose of Octreotide-soln in human. Rats are fasted for 12 h before dosing and food is returned approximately 2 h post dosing. Blood samples are collected at predetermined time points using heparinized Eppendorf tubes. Immediately after collection, the blood samples are placed on ice until centrifuged at 3000 g for 10 min within 1 h. The plasma is collected and stored at ?20°C until analysis. |
