Background:

Ki = 0.16 nM: α1A-adrenoceptor antagonist


IC50s = 0.4 μM: inhibits L-type Ca2+ channels


IC50s = 0.9 μM: suppresses T-type Ca2+ channels


Niguldipine is a less potent Ca2+ channel blocker and potent, selective α1A-adrenoceptor receptor antagonist. Ca2+ channels, expressed in the smooth muscles of the male reproductive tract, play a role in the physiological events involved in the seminal emission phase of ejaculation. It was demonstrated that α1-adrenoceptors, as members of superfamily of G protein-coupled receptors, are not a homogeneous population and have three distinct α1-adrenoceptor subtypes, involving α1A, α1B, and α1D.


In vitro: Niguldipine significantly increased the rate of long-lived protein degradation in human glioblastoma H4 cell, which indicated that niguldipine triggered autophagic degradation without inducing obvious cellular damage. Also, niguldipine blocked intracellular Ca2+ currents [1].


In vivo: Female Albino Swiss mice were administered intraperitoneally in a volume of 10 ml/kg niguldipine for 30 min. Niguldipine did not affect the electroconvulsive threshold in mice. Compared to the anticonvulsive activity of niguldipine against electroconvulsions, niguldipine remarkably impaired the protective action of both phenobarbital and carbamazepine [2].
