In Vivo

sst2 Receptor agonist-1 (compound 21) (0.2 or 2 mg/kg; IV; single dosage) shows a dose-dependent decrease in growth hormone (GH) secretion[1].
sst2 Receptor agonist-1 (5 or 15 μg/per eye; intraocular; once every 4 days) reduces neovascular lesion area in laser choroidal neovascularization (CNV) rat model[1].

Animal Model: Female Wistar rats (200-250 g; IP injection with 50 mg/kg pentobarbital, then injected with tested compound via jugular cannula, after 40 or 50 min administration, injected with GH secretagogue via jugular cannula)[1]
Dosage: 0.2 or 2 mg/kg
Administration: IV; single dosage
Result: Caused a dose-dependent decrease in GH secretion (38 and 91% reduction in plasma GH AUC following administration of 0.2 and 2 mg/kg, respectively).
Animal Model: Male Brown Norway rats (175-225 g; lasered and perfused, a 27G needle was used to make a small hole in the eye 3 mm posterior to iris angled 45° toward the optic nerve)[1]
Dosage: 5 or 15 μg/per eye, 5 μL
Administration: Intraocular administration; inject at day 0, 4 and 8
Result: Exhibited a dose-dependent antiangiogenic effect by a 35 and 53% reduction in neovascular lesion area with 5 or 15 μg per eye, respectively.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
