D-Menthol ((+)-MENTHOL) is a common compound in pharmaceutical and commercial products and a popular additive to cigarettes, it attenuates α±7 mediated Ca 2+ transients in the cell body and neurite, suggests that menthol inhibits α±7-nACh receptors in a noncompetitive manner.

1-Octanol, a saturated fatty alcohol, functions as an inhibitor of T-type calcium channels (T-channels), showing an inhibitory concentration (IC50) of 4 μM for native T-currents[1]. Additionally, 1-Octanol is recognized for its potential as a biofuel, possessing diesel-like properties[2].

Nisoldipine (BAY-k 5552) is a dihydropyridine calcium channel antagonist that acts as a potent arterial vasodilator and antihypertensive agent.

Diltiazem hydrochloride (RG 83606 HCl) is a benzothiazepine calcium channel blocking agent with vasodilating action due to its antagonism of the actions of CALCIUM ion on membrane functions.

Nifedipine (Procardia) is a dihydropyridine calcium channel blocking agent. Nifedipine inhibits the transmembrane influx of extracellular calcium ions into myocardial and vascular smooth muscle cells, causing dilatation of the main coronary and systemic arteries and decreasing myocardial contractility. This agent also inhibits the drug efflux pump P-glycoprotein which is overexpressed in some multi-drug resistant tumors and may improve the efficacy of some antineoplastic agents.

Levetiracetam (SIB-S1) is a relatively unique anticonvulsant that is typically used in combination with other antiepileptic medications for partial onset seizures. Levetiracetam has been linked to rare instances of serum aminotransferase and alkaline phosphatase elevations during treatment and to rare cases of clinically apparent drug induced liver disease.

Otilonium bromide (SP63) , an antimuscarinic, is utilized as a spasmolytic agent.

Methyl homoveratrate, a McN5691 (RWJ-26240) metabolite detected in vivo in plasma, urine, and fecal extracts, functions as a voltage-sensitive calcium channel blocker.
