ICA-121431 (2,2-Diphenyl-N-[4-(thiazol-2-ylsulfamoyl) 是强效的、广谱的电压门控钠通道阻滞剂，对人 Nav1.1 和 Nav1.3 亚型具有等效选择性，IC50分别为 13 nM 和 23 nM。它对Nav1.2 的抑制作用较弱，IC50为240 nM，对 Nav1.4、Nav1.6、抗TTX 的人 Nav1.5、Nav1.8 通道表现出大于 1000 倍的选择性，IC50>10 μM。

Zonisamide-13C2,15N is intended for use as an internal standard for the quantification of zonisamide by GC- or LC-MS. Zonisamide is an antiepileptic agent.1 It selectively inhibits the repeated firing of sodium channels (IC50 = 2 μg ml) in mouse embryo spinal cord neurons and inhibits spontaneous channel firing when used at concentrations greater than 10 μg ml.2 In rat cerebral cortex neurons, zonisamide (1-1,000 μM) inhibits T-type calcium channels with a maximum reduction of 60% of the calcium current.3 Zonisamide inhibits H. pylori recombinant carbonic anhydrase (CA) and the human CA isoforms I, II, and V with Ki values of 218, 56, 35, and 21 nM, respectively.4,5 In mice, it has anticonvulsant activity against maximal electroshock seizure (MES) and pentylenetetrazole-induced maximal, but not minimal, seizures (ED50s = 19.6, 9.3, and >500 mg kg, respectively). Zonisamide (40 mg kg, p.o.) prevents MPTP-induced decreases in the levels of dopamine , but not homovanillic acid or dihydroxyphenyl acetic acid , and increases MPTP-induced decreases in the dopamine turnover rate in mouse striatum in a model of Parkinson's disease.6 Formulations containing zonisamide have been used in the treatment of partial seizures in adults with epilepsy. |1.

Vercirnon (GSK1605786A) sodium is an orally bioavailable, selective, and potent antagonist of CCR9 . Vercirnon sodium inhibits CCR9-mediated Ca 2+ mobilization and chemotaxis on Molt-4 cells with IC 50 values of 5.4 and 3.4 nM, respectively. Vercirnon sodium is selective for CCR9 over CCR1-12 and CX3CR1-7 (IC 50 s>10 μM for all). Vercirnon sodium is an equipotent inhibitor of CCL25-directed chemotaxis of both splice forms of CCR9 (CCR9A and CCR9B) with IC 50 values of 2.8 and 2.6 nM, respectively.
