生物活性:
Octreotide (SMS 201-995) pamoate is a somatostatin receptor agonist and synthetic octapeptide endogenous somatostatin analogue. Octreotide pamoate can bind to the somatostatin receptors which are mainly subtypes 2, 3 and 5. Octreotide pamoate increases Gi activity and reduces intracellular cAMP production. Octreotide pamoate has antitumor activity, mediates apoptosis and may also be used in disease studies in acromegaly.
体内研究:
Octreotide pamoate (subcutaneous injection, 30 mg/kg, once) can inhibit tumor growth significantly with no effect on body weight.Octreotide pamoate (intramuscular injection, 60 mg/kg, every 21 days, 42 days) inhibits serum insulin-like growth factor (IGF-I) without toxicity in dogs with appendicular osteosarcoma (OSA).Octreotide pamoate (subcutaneous injection, 40 μg/kg, Every 12 hours, 8 days) improves hepatic glycogen synthesis in obese male Sprague?Dawley (SD) rats.Animal Model:Female nude mice (nu/nu Balbc-A weighing 19-22 g)
Dosage:30 mg/kg
Administration:Subcutaneous injection; once
Result:Showed that the average volume of tumors treated was 25.8% of the control group and no effect on body weight.
Animal Model:Dogs with appendicular OSA
Dosage:60 mg/kg
Administration:Intramuscular injection; every 21 days; 42 days
Result:Resulted in a 43% decrease in mean serum IGF-I compared with mean baseline concentrations.
Animal Model:Male Sprague?Dawley (SD) rats (3 weeks; 40-60 g)
Dosage:40 μg/kg
Administration:Subcutaneous injection; every 12 hours; 8 days
Result:Significantly improved fat deposition and reduced lipid infiltration.
体外研究:
