rat m4 receptor

VU0467154 是 M4 毒蕈碱的乙酰胆碱受体的正向调节剂，能够增强小鼠、人和食蟹猴 M4 受体对乙酰胆碱的反应，pEC50值分别为 7.75、6.2 和 6。

VU6005806 is a potent positive allosteric modulator (PAM) of muscarinic acetylcholine receptor subtype 4 (M4) (EC50s: 94 nM, 28 nM, 87 nM, and 68 nM for human, rat, dog, and cyno M4, respectively), and used in the study of neuropsychiatric disorders.

VU0467485 is a potent and selective muscarinic acetylcholine receptor 4 positive allosteric modulator. VU0467485 potentiates the activity of ACh at M4 (EC50s: 26.6 nM and 78.8 nM at the rat and human M4 receptors, respectively). VU0467485 displays selecti

Methoctramine is a selective antagonist of M2 muscarinic acetylcholine receptors (IC50 = 6.1 nM in CHO-K1 cell membranes).[1] It is selective for M2 over M1, M3, M4, and M5 receptors (IC50s = 92, 770, 260, and 217 nM, respectively). In vitro, methoctramine inhibits acetylcholine-induced reductions in isolated guinea pig tracheal tube contractions when used at a concentration of 1 μM.[2] In vivo, methoctramine inhibits bradycardia and bronchoconstriction induced by acetylcholinein guinea pigs with ED50 values of 38 and 81 nmol kg, respectively. In a rat model of spinal cord injury, methoctramine suppresses bladder overactivity induced by the non-selective muscarinic acetylcholine receptor agonist oxotremorine M.[3]

RO1138452 (CAY10441) 是一种选择性和可口服的前列环素受体拮抗剂，pKi 为8.3。它拮抗卡前列环素诱导的人神经母细胞瘤腺苷酸环化酶的激活，以剂量依赖性方式阻断环 AMP 积累，具有镇痛活性。
