Metoclopramide 是一种有效的5-HT3和多巴胺D2受体拮抗剂,IC50值分别为 308 nM 和 483 nM。Metoclopramide 可用于恶心呕吐、胃食管反流和胃轻瘫的研究。
生物活性 | Metoclopramide is a potent antagonist of5-HT3anddopamine D2 receptor, withIC50s of 308 nM and 483 nM, respectively. Metoclopramide can be used for the research of nausea and vomiting, gastro-oesophageal reflux, and gastroparesis[1][2]. |

体外研究 (In Vitro) | Metoclopramide (0.01-10 μM) stimulates aldosterone release in isolated perfused rat zona glomerulosa cells[3]. Metoclopramide results in prokinesis by four mechanisms: inhibition of presynaptic D2 receptors and stimulation of presynaptic excitatory 5-HT4 receptors, thereby allowing acetylcholine (ACh) release from intrinsic cholinergic motor neurons; inhibition of D2 postsynaptic receptors; and antagonism of the presynaptic inhibition of muscarinic receptors, leading to further augmentation of ACh release[2].

体内研究 (In Vivo) | Metoclopramide (6.7 μg/g; s.c. daily for 50 days) significantly increases the number and the volume of lactotroph cells of the pituitary gland during all phases of the estrous cycle[4]. Metoclopramide (5-40 mg/kg; i.p.) induces catalepsy and antagonizes Apomorphine induced cage climbing behaviour in mice[5]. Metoclopramide (1.25-2.5 mg/kg; i.p.) induces stereotyped cage climbing behaviour in mice[5].
Animal Model: | Adult, virgin female mice of the Swiss EPM-1 strain[4] | Dosage: | 6.7 μg/g | Administration: | S.c. daily for 50 days | Result: | Increased the number but also stimulated the metabolic activity of lactotrophs. |
