• 产品描述： Otenzepad (AF-DX 116) is a selective and competitive M2 muscarinic acetylcholine receptor antagonist, with IC50 values of 640 nM and 386 nM for rabbit peripheral lung and rat heart, respectively

• 靶点： 640 nM (M2 muscarinic acetylcholine receptor in rabbit peripheral lung), 386 nM (M2 muscarinic acetylcholine receptor in rat heart);AChR

• 体外研究：
  Otenzepad (0.5, 1 mg/kg, s.c., in rats) significantly improved win-stay acquisition relative to vehicle-injected controls.
  Otenzepad (2 mg/kg, s.c., in rats) significantly improved retention relative to vehicle controls.
  Otenzepad (0.3, 1.0, or 3.0 mg/kg, ip, in mice) potentiates the effects of glucose and reverses the effects of insulin on memory.

  Otenzepad (0.5, 1 mg/kg, s.c., in rats) significantly improved win-stay acquisition relative to vehicle-injected controls. Otenzepad (2 mg/kg, s.c., in rats) significantly improved retention relative to vehicle controls. Otenzepad (0.3, 1.0, or 3.0 mg/kg, ip, in mice) potentiates the effects of glucose and reverses the effects of insulin on memory. Animal Model: Forty-eight male Long-Evans rats (325-350 g). Dosage: 0.25, 0.5, 1.0 and 2.0 mg/kg. Administration: S.C. on the dorsum of the neck once. Result: Doses of 0.5 and 1.0 mg/kg significantly improved acquisition relative to vehicle controls, while doses of 0.25 and 2.0 mg/kg had no effect. Animal Model: Adult male Swiss mice (age 60–70 days; weight 25-30 g). Dosage: 0.3, 1.0, or 3.0 mg/kg. Administration: IP once. Result: Enhanced retention in an inverted-U dose–response manner, with significant enhancement seen at 1.0 mg/kg (U15,15 = 49, p < 0.02, compared with saline-saline-injected control group).
