The results suggest that the blockade of neurotoxin receptor site 2 of VSSC in the brain contributes to the neuroprotective action of NS-7.
Irsogladine, an anti-ulcer drug, suppresses superoxide production by inhibiting phosphodiesterase type 4 in human neutrophils.

NS-21 is a newly developed drug for the treatment of urinary frequency and urinary incontinence and it has pharmacological properties similar to those of terodiline, however, whether NS-21 and its active metabolite, RCC-36, have any proarrhythmic activity.
Cerebroprotective action of a Na+/Ca2+ channel blocker NS-7 I. Effect on the cerebral infarction and edema at the acute stage of permanent middle cerebral artery occlusion in rats
Inhibition of Depolarization‐Induced Nitric Oxide Synthase Activation by NS‐7, a Phenylpyrimidine Derivative, in Primary Neuronal Culture
The present findings suggest that this compound inhibits depolarization‐induced NOS activation by reducing Ca2+ influx through blockade of Na+ and Ca2- channels in primary neuronal culture.

It is suggested that inhibition of calpain activation is implicated in the neuroprotective action of NS‐7, which produced a concentration‐dependent inhibition of hypoxia/hypoglycemia‐induced fodrin breakdown.
Involvement of peroxynitrite and hydroxyradical generated from nitric oxide in hypoxia/reoxygenation injury in rat cerebrocortical slices
Blockade by NS‐7, a Neuroprotective Compound, of Both L‐Type and P/Q‐Type Ca2+ Channels Involving Depolarization‐Stimulated Nitric Oxide Synthase Activity in Primary Neuronal Culture
It is suggested that NS‐7 inhibits NOS activation in primary neuronal culture by reducing Ca2+ entry through L‐type and P/Q‐type Ca 2+ channels, in which the inhibition is largely dependent on Ca2- channel activity.
