Pyrithiamine hydrobromide（啶硫胺氢溴酸盐）是一种硫胺素代谢抑制剂，作为硫胺素焦磷酸激酶的底物发挥作用，在动物中引起类似wernickke - korsakoff综合征的神经系统症状。

A-971432 is a sphingosine-1-phosphate receptor 5 (S1P5) agonist that is selective for S1P5 over S1P1 and S1P3 (IC50s = 0.006, 0.362, and >10 µM, respectively). It inhibits forskolin-induced cAMP production in CHO cells expressing S1P5 (EC50 = 4.1 nM). A-971432 (1 µM) increases electrical resistance of hCMEC D3 cells in an in vitro blood-brain barrier model, indicating enhanced barrier integrity, and attenuates blood-brain barrier leakage in an R6 2 transgenic mouse model of Huntington’s disease when administered at a dose of 0.1 mg kg.[1] [2] A-971432 (0.1 mg kg per day, i.p.) decreases the number of errors made in a horizontal ladder task and increases latency to fall in the rotarod test in R6 2 mice. It also increases spontaneous alternation in the t-maze in aged mice when administered at a dose of 0.1 mg kg.[1] References [1].Hobson, A.D., Harris, C.M., van der Kam, E.L., et al.

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.
