presynaptic d2 receptor

lumateperone Tosylate (ITI-007) 是5-HT 2A 受体拮抗剂，Ki 为 0.54 nM，突触前 D2受体的部分激动剂和突触后 D2受体的拮抗剂，Ki 为 32 nM。

Lumateperone (ITI 722) 是一种 5HT2A 受体拮抗剂和多巴胺受体磷蛋白调节剂 (DPPM)。

Carmoxirole (free base) is a dopamine D2 receptor agonist with limited central activity that modulates sympathetic activation and subsequently reduces pre-load and afterload in animals. It was shown, that carmoxirole induced beneficial effects on hemodynamic and neurohumoral parameters in heart failure. In addition, experimental evidence showed that carmoxirole lowered blood pressure in various models of hypertension mainly or exclusively through inhibition of noradrenaline release from sympathetic nerve endings. That effect of carmoxirole was mediated by presynaptic dopamine receptors with the characteristic that release inhibition was restricted to low rates of sympathetic nerve discharge.

OPC 4392 hydrochloride 作为突触前多巴胺受体 (dopamine receptor) 的激动剂以及突触后D2受体的拮抗剂，具有显著的生物活性。该化合物能有效逆转由Reserpine引起的多巴胺积累，并在Apomorphine诱导的小鼠模型中抑制刻板行为和攀爬行为。
