Ulixacaltamide
Based on 1 publication(s) in Google Scholar
Ulixacaltamide (Z944) is an orally available T-type calcium channel antagonist that can slow the progression of epilepsy. Ulixacaltamide effectively reduces tremor in a normal alkaline tremor animal model. Ulixacaltamide reverses thermal hyperalgesia and mediates pain relief.

Ulixacaltamide (1 μM) inhibits the whole-cell current amplitude of transiently expressed human Cav3.2 calcium channels by approximately 50% (IC50=0.60 μM)[4]. Ulixacaltamide (10 μM) abolishs completely the transient current component generated by depolarization to 30 mV after activation of T-type calcium channels, reducing the whole-cell calcium current of tsA-201 cells by approximately 70%[4].
