Octreotide acetate 生物活性

描述 Octreotide acetate, a long-acting synthetic analog of native somatostatin, inhibits growth hormone, glucagon, and insulin more potently. Octreotide-treated groups show a significant reduction in the tumor volume when compared with saline group. Octreotide-PPSG (1.4 mg/kg, i.p.) shows greater antitumor effect than Octreotide-soln (100 μg/kg, i.p.). Octreotide-treatments results in significant inhibitory effect on the expression levels of SSTR2 and SSTR5 in primary HCC-bearing rats compared with the saline group[3]. Octreotide can decrease the rate of postoperative complication after pancreatic resection by diminishing exocrine function of the pancreas. Prophylactic octreotide is not effective to inhibit the exocrine secretion of the remnant pancreas and does not decrease the incidence of pancreatic fistula after pancreaticoduodenectomy[4]. The prophylactic use of LAO (long-acting octreotide acetate) did not prevent the incidence or reduce the severity of diarrhea and had no notable impact on patient-reported bowel function or QoL(quality of life)[5]. Octreotide LAR (octreotide acetate) 20 mg shows significant efficacy in terms of objective response rate (PR + SD), biochemical and symptomatic control in patients with metastatic NETs (neuroendocrine tumors) of the GEP system pretreated and progressing on slow release lanreotide[6].

溶解方案

DMSO: 250 mg/mL(231.63 mM),配合低频超声助溶,注意:DMSO长时间开封后,会吸水并导致溶解能力下降,请避免使用长期开封的DMSO

H2O: 25 mg/mL(23.16 mM),配合低频超声助溶

请根据您的动物给药指南选择适当的溶解方案。
以下溶解方案都请先按照体外实验的方式配制澄清的储备液,再依次添加助溶剂:
——为保证实验结果的可靠性,澄清的储备液可以根据储存条件,适当保存;体内实验的工作液,建议现用现配,当天使用; 以下溶剂前显示的百分比是指该溶剂在终溶液中的体积占比;如在配制过程中出现沉淀、析出现象,可以通过加热和/或超声的方式助溶
方案一
方案二
配制的工作液建议现用现配,短期内尽快用完。 以下溶剂前显示的百分比是指该溶剂在终溶液中的体积占比;如在配制过程中出现沉淀、析出现象,可以通过加热和/或超声的方式助溶
