ABC34 is an inactive control probe for JJH260 , the inhibitor of androgen-induced gene 1 (AIG1), an enzyme that hydrolyzes fatty acid esters of hydroxy fatty acids (FAHFAs). ABC34 demonstrates an IC50 value greater than 25 μM for the inhibition of 9-PAHSA but is more potent in blocking the serine hydrolase ABHD6 and the palmitoyl-protein hydrolase PPT1, which are both off-targets of JJH260.

GEBR-7b (3-(Cyclopentyloxy)-4-methoxybenzaldehyde) 是一种磷酸二酯酶 4 (PDE4) 抑制剂。

VP3.15 dihydrobromide 是一种口服具有活力的、高效的、CNS 可渗透的PDE7-GSK3双重抑制剂，对 PDE7 和 GSK3 作用的IC50值分别为 1.59 μM 和 0.88 μM。它具有神经保护和神经修复作用，可用于研究多发性硬化症 (MS) 潜在的抗炎和促髓鞘再生联合。

Benserazide hydrochloride (Ro 4-4602) 是一种芳香族 L-氨基酸脱羧酶（AADC）的抑制剂，常用于帕金森病。

PF-04449613 is a phosphodiesterase 9A (PDE9A) inhibitor (IC50= 22 nM).1It is selective for PDE9A over PDE1C (IC50= >1,000 nM), as well as over a variety of other PDEs, inhibiting PDE2-8, -10, and -11 activity by less than 30% in a panel of enzymes, ion channels, and transporters at 1 μM but does inhibit the human dopamine transporter (DAT; Ki= 293 nM). PF-04449613 (0.1-100 mg/kg, s.c.) increases cerebrospinal fluid (CSF) levels of cyclic GMP (cGMP) in rats. Subcutaneous administration of PF-04449613 (10 mg/kg) increases the rate of dendritic spine formation and elimination in mouse primary motor cortex pyramidal neuronsin vivo.2It increases the average running speed of mice in an accelerating rotarod task, indicating improved motor learning, at the same dose. 1.Claffey, M.M., Helal, C.J., Verhoest, P.R., et al.Application of structure-based drug design and parallel chemistry to identify selective, brain penetrant, in vivo active phosphodiesterase 9A inhibitorsJ.
