Medetomidine 美托咪定

产品介绍 Medetomidine 是一种具有口服活性的 α2 肾上腺素受体 (α2-adrenoceptor) 激动剂 (Ki: 1.08 nM)。Medetomidine 具有镇静和镇痛作用。Medetomidine 可通过激活血管上的 α2 肾上腺素能受体引起外周血管收缩。
生物活性

Medetomidine is an orally active α2-adrenoceptor agonist (Ki: 1.08 nM). Medetomidine has sedative and analgesic effects. Medetomidine can cause peripheral vasoconstriction through the activation of α2 adrenoceptors on blood vessels[4].

体外研究

Medetomidine (0-1 µM, 1 h) inhibits aldosterone release from the adrenocortical cell suspension[7].
Medetomidine (10 nM) activates a kicking response in Cyprids[8].
Medetomidine (1 µM) increases cellular cAMP production by activating β-like receptors in CHO cells[8].

西域 has not independently confirmed the accuracy of these methods. They are for reference only.

体内研究

Medetomidine (200 μg/kg, p.o. or i.m.) induces a sedation in cats[4].
Medetomidine (20 µg/kg, i.v.) shows sedative and analgesic effects in dogs[5].
Medetomidine (0.05-0.3 mg/kg, s.c.) protects against Diazinon-induced toxicosis in mice[6].

西域 has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Diazinon (75 mg/kg, orally)-induced toxicosis in mice[6]
Dosage: 0.05, 0.1 and 0.3 mg/kg
Administration: Subcutaneous injection (s.c.), 15 min before Diazinon.
Result: Protected the mice from the toxicity induced by Diazinon.
Decreased the occurrence of Straub tail, excessive salivation and tremor.
Increased the latencies to onset of tremor and death when compared with control.
Animal Model: Dogs[5]
Dosage: 20 µg/kg
Administration: Intravenous injection (i.v.)
Result: Showed sedative and analgesic effects. Increased in SAP, MAP, DAP, MPAP, PCWP, CVP, SVR, PVR, core body temperature.
Decreased in HR, CO, CI, SV, SI, RR, pH.
