PF-00446687 是一种有效的，脑渗透性的，选择性黑皮质素 4 受体 (MC4R) 激动剂，EC50 为 12 ± 1 nM。

PF-00446687 is a potent, selective melanocortin-4 receptor (MC4R) agonist with EC50 of 12?±?1 nM. Pf-446687 is brain penetrant.

Solid

EC50: 12?±?1 nM (MC4R)

PF-00446687 binds MC4 receptor with a Ki of 27±4 nM. PF-00446687 has a relatively weak activity at the MC1, MC3, and MC5 receptors with EC50s of 1.02±0.30 μM, 1.16±0.35 μM, and 1.98±0.20 μM, respectively. The broad off-target profiles of PF-00446687 are assessed in the CEREP Bioprint wide ligand screening panel, with the most potent binding activities being at the σ receptor (Ki=330 nM), the sodium ion channel (Ki=690 nM), and the muscarinic M2 receptor (Ki=730 nM). has not independently confirmed the accuracy of these methods. They are for reference only.

Pf-446687 is highly selective for MC4R and is both brain penetrant and stable in vivo. Peripheral administration of the brain penetrant MC3/4R receptor peptide agonist, Melanotan II (MTII), and the highly selective, small molecule MC4R agonist, Pf-446687, enhances partner preference formation in the prairie vole, but not in the non-monogamous meadow vole. has not independently confirmed the accuracy of these methods.
