Biological Activity

DSO-5a (Dimethyl shikonin oxime 5a) is a potent, selective agonist pf bombesin receptor subtype-3 (BB3, BRS-3) with pEC50 of 8.4 (IP-1 accumulation in hBB3-H1299 cells).
DSO-5a did not elicit detectable calcium response in parental cells but elicited a strong calcium response in hBB3-H1299 cells with a pEC50 value of 7.964, Bantag-1 blocked these calcium responses in a dose-dependent manner.
DSO-5a induced a dose-dependent IP-1 accumulation with a pEC50 value of 7.262 in mBB3-HEK cells.
DSO-5a elicited IP-1 accumulation with pEC50 value of 9.357 in B16 cells.
DSO-5a (3 mg/kg; 10 mg/kg; 30 mg/kg) 30 min before glucose challenge (3 g/kg) reduced blood glucose excursions in a dose-dependent manner in C57BL/6 mice.
