12211084 Thumen A, Qadri F, Sarkar R, Moser A: GBR-12909 effect on dopamine outflow depends on phosphorylation in the caudate nucleus of the rat. Synapse. 2002 Nov;46(2):72-8.

These results suggest a complex and strong influence of phosphorylation on GBR-12909 effects on calcium channel-dependent DA outflow at low-affinity piperazine binding sites in slices of the rat caudate nucleus in vitro.

18987207 Newton PM, Zeng L, Wang V, Connolly J, Wallace MJ, Kim C, Shin HS, Belardetti F, Snutch TP, Messing RO: A blocker of N- and T-type voltage-gated calcium channels attenuates ethanol-induced intoxication, place preference, self-administration, and reinstatement. J Neurosci. 2008 Nov 5;28(45):11712-9.

We demonstrate that pretreatment with the novel mixed N-type and T-type calcium channel antagonist 1-(6,6-bis (4-fluorophenyl) hexyl)-4-(3,4,5-trimethoxybenzyl) piperazine (NP078585) reduced ethanol intoxication.

This work assessed the potential of the calcium channel blocker (E)-1-bis (4-fluorophenyl) methyl-4-(3-phenyl-2-propenyl) piperazine dihydrochloride (flunarizine) as a pretreatment to ameliorate this extravasation.

Among the library with 5 features, alkaneamide derivatives (7b, 9j, 11b, 11g, 11h) with 4-arylsubstituted piperazine showed better IC (50) values than Mibefradil.

Compounds of the current series showed optimum activity when the aliphatic alkyl chain on the salicylamide nitrogen is part of a piperidine or piperazine ring system substituted at the terminal nitrogen with a benzyl group.

The present study was undertaken to investigate the effect of diltiazem, a L-type calcium channel blocker (CCB), on the behavior of zolpidem-treated mice in the elevated plus-maze (EPM).
Zolpidem also attenuated the anxiogenic effect of 1-(3-Chlorophenyl) piperazine (mCPP, 0.7 mg/kg, i.p.) and 5-hydroxytryptophan (5-HTP, 30 mg/kg, i.p.).

Ranolazine is a piperazine derivative believed to reduce anginal symptoms by preventing ischemia-mediated sodium and calcium overload in myocardial cells through inhibition of the late sodium current (late INa).
Three small studies demonstrated the antianginal efficacy of ranolazine alone and in combination with betablockers or calcium channel blockers on conventional end points such as total exercise duration and time to ischemia/angina on a treadmill; however, questions of safety related to QT prolongation, efficacy in women and potential utility in higher risk populations remained.

Cinnarizine, a piperazine derivative, is a widely prescribed medication for the treatment of vestibular disorders and motion sickness.
Cinnarizine has antihistaminic, antiserotoninergic, antidopaminergic, and calcium channel-blocking properties.

Our data suggest that T-type calcium channel antagonism may contribute to the pharmacology of trazodone and its reported neurological effects.

11259531 McKune CM, Watts SW: Characterization of the serotonin receptor mediating contraction in the mouse thoracic aorta and signal pathway coupling. J Pharmacol Exp Ther. 2001 Apr;297(1):88-95.

Our hypothesis was further supported by the finding that antagonists with affinity for the 5-HT2A receptor, ketanserin, 1-(1-naphthyl) piperazine, spiperone, and LY53857, reduced 5-HT-induced contraction.
The L-type calcium channel blockers nifedipine and nitrendipine, PLC inhibitor 2-nitro-4-carboxyphenyl N,N-diphenylcarbamate, and tyrosine kinase inhibitors genistein and PD 098,059 all shifted and/or reduced maximum contraction to 5-HT.

Here we investigate changes in mesocorticolimbic DA efflux following administration of NP078585, a novel orally available calcium channel blocker exhibiting high affinity block of N- and T-types versus P/Q- and L-types.
