“Furthermore, other organic T-type … such as phenytoin, ethosuximide , an arylpiperidine derivative SUN N5030 (IC(50)=0.32 micro … -60 mV for alpha1G) also exhibited comparable inhibitory efficacies for NICC currents (inhibited by 22% at 100 micro M; IC(50)=….8 mM; IC(50)=0.53 micro M, respectively).”
