Procainamide Hydrochloride (Procapan) is the hydrochloride salt form of procainamide, an amide derivative exhibiting class 1A antiarrhythmic property and analog of procaine. Procainamide hydrochloride reversibly binds to and blocks activated (open) voltage-gated sodium channels, thereby blocks the influx of sodium ions into the cell, which leads to an increase in threshold for excitation and inhibit depolarization during phase 0 of the action potential.

Bupivacaine hydrochloride (Vivacaine) is a long-acting, amide-type local anesthetic. Bupivacaine hydrochloride reversibly binds to specific sodium ion channels in the neuronal membrane, resulting in a decrease in the voltage-dependent membrane permeability to sodium ions and membrane stabilization; inhibition of depolarization and nerve impulse conduction; and a reversible loss of sensation.

Prilocaine hydrochloride (Prilocaine HCl) is a local anesthetic of the amino amide type, binds to voltage-gated sodium ion channels in the neuronal membrane, thereby preventing the permeability of sodium ions.

Propafenone (Propafenonum) is only found in individuals that have used or taken this drug. It is an antiarrhythmia agent that is particularly effective in ventricular arrhythmias. It also has weak beta-blocking activity. The drug is generally well tolerated. The electrophysiological effect of propafenone manifests itself in a reduction of upstroke velocity (Phase 0) of the monophasic action potential. In Purkinje fibers, and to a lesser extent myocardial fibers, propafenone reduces the fast inward current carried by sodium ions, which is responsible for the drugs antiarrhythmic actions. Diastolic excitability threshold is increased and effective refractory period prolonged. Propafenone reduces spontaneous automaticity and depresses triggered activity. At very high concentrations in vitro, propafenone can inhibit the slow inward current carried by calcium but this calcium antagonist effect probably does not contribute to antiarrhythmic efficacy.

Trisodium HEDTA (HEDTA-Na3) is a chelating agent that chelates sodium ions and acts as a chelating agent in cosmetic formulations.

Gramicidin (Gramicidine) is an antimicrobial peptide. Gramicidin dimers form ion channel-like pores in the cell membranes and organelles of bacterial and animal cells, allowing inorganic monovalent ions, such as potassium and sodium ions, to pass freely through the pores by diffusion, disrupting the important ionic gradient between membranes and thus killing the cells by various actions. Gramicidin is effective against Gram-positive bacteria such as Bacillus subtilis and Staphylococcus aureus, but is not as effective against Gram-negative bacteria such as Escherichia coli.

Cyclopenthiazide (Cyclomethiazide) is a thiazide diuretic used to treat hypertension and heart failure. It decreases the excretion of calcium ions and uric acid and increases the excretion of sodium and potassium ions.

Amiloride hydrochloride dihydrate (Amiloride HCl dihydrate) is a pyrazine compound inhibiting SODIUM reabsorption through SODIUM CHANNELS in renal EPITHELIAL CELLS. This inhibition creates a negative potential in the luminal membranes of principal cells, located in the distal convoluted tubule and collecting duct. Negative potential reduces secretion of potassium and hydrogen ions. Amiloride hydrochloride dihydrate is used in conjunction with DIURETICS to spare POTASSIUM loss.

Oxybuprocaine is an ester-type local anesthetic that is used especially in ophthalmology and otolaryngology. Oxybuprocaine binds to sodium channels and reversibly stabilizes the neuronal membrane which decreases its permeability to sodium ions.

Ilaprazole sodium (IY-81149 sodium) , a substituted benzimidazole prodrug, is a selective and irreversible proton pump inhibitor. A weak base, Ilaprazole accumulates in the acidic environment of the secretory canaliculus of the gastric parietal cell where it is converted to an active sulfenamide form that binds to cysteine sulfhydryl groups on the luminal aspect of the proton pump hydrogen-potassium adenosine triphosphatase (H+ K+ ATPase), thereby inhibiting the pump's activity and the parietal cell secretion of H+ ions into the gastric lumen, the final step in gastric acid production.

The compound Sodium Glucoheptonate (H-Quest A300), also known as Sodium Glucoheptonate, is a non-toxic and harmless chelating agent capable of forming stable complexes with divalent and trivalent metal ions such as Ca2+, Fe2+, Fe3+, and Al3+.

ErSO-TFPy activates the sodium ion channel TRPM4, resulting in an imbalance of intracellular calcium and sodium ions. It exhibits low nanomolar-level cytotoxicity (IC50 = 5-25 nM) by inducing necrosis in ERα+ breast cancer cell lines. Additionally, ErSO-TFPy shows antitumor activity in mouse models.

8-CPT-2Me-cAMP sodium is a sodium salt compound that selectively activates exchange proteins activated by cAMP (Epac), which are cAMP-sensitive guanine nucleotide exchange factors (GEFs) responsible for activating small GTPases Rap1 and Rap2. It specifically activates Epac1 with an EC50 value of 2.2 μM, while showing no activation of PKA with an EC50 value greater than 10 μM [1]. Additionally, 8-CPT-2Me-cAMP sodium stimulates the Epac-mediated release of calcium ions (Ca2+) in vitro in pancreatic β-cells [2].

Cis-ACBD (cis-1-aminocyclobutane-1,3-dicarboxylic acid) is a potent and selective N-methyl-D-aspartate receptor agonist.

Deethylindanomycin is a polyether antibiotic that has been found in S. setonii. It is active against a variety of Gram-positive bacteria, including various strains of S. aureus and Streptococcus, as well as one strain of S. pneumoniae (MICs = 4, 4, and 2 μg ml, respectively). It is also active against coccidia in vitro, inhibiting E. tenella development, but is inactive against E. tenella infection in chicks when administered at a dose of 200 μg g in the diet. Deethylindanomycin acts as an ionophore in lipid bilayer membranes and is more selective for potassium ions than calcium, magnesium, and sodium ions. It induces histamine release from rodent mast cells and human basophils in vitro in a calcium-dependent manner.

5-chloro Hydrochlorothiazide is a derivative of hydrochlorothiazide, which is a diuretic and antihypertensive agent that increases renal excretion of sodium, potassium, chloride, and bicarbonate ions by inhibiting tubular reabsorptive mechanisms.

Tetranactin is a macrotetrolide and a monovalent cation ionophore that has been found in S. aureus and has antibacterial, insecticidal, and mitogenic activities. It exhibits an equilibrium permeability ratio 1,000-fold greater for lithium than sodium or cesium ions accross bilayer membranes at low voltages. Tetranactin inhibits the growth of Gram-positive bacteria and C. miyabeanus and R. solani fungi when used at concentrations less than 0.9 μg/ml. Tetranactin (0.5-1.5 μg per insect) dose-dependently increases the mortality of adult C. chinensis weevils up to 100% and has mitogenic activity against T. telarius when sprayed onto plants with an LC50 value of 9.2 μg/ml. It reduces IL-1β- and cAMP-induced secretion of phospholipase A2 (PLA2) from rat mesangial cells (IC50s = 43 and 33 nM, respectively). Tetranactin (50 ng/ml) suppresses the proliferation of human T lymphocytes induced by allogeneic cells and IL-2 and supresses the generation of cytotoxic T lymphocytes in mixed lymphocyte cultures. In vivo, tetranactin (10 mg/animal per day) completely inhibits the formation of experimental autoimmune uveoretinitis (EAU) in rats.

TRPC6-IN-3 (compound 17) is an orally active inhibitor of the transient receptor potential C6 ion channel (TRPC6), which regulates intracellular calcium concentration and modulates the flux of cations, including calcium and sodium ions, thereby affecting membrane potential.

Potassium ionophore III (BME-44) serves as a highly lipophilic, selective carrier for potassium ions, demonstrating pronounced selectivity over sodium and ammonium ions.

3,5-DiBr-PAESA (sodium) serves as an ultrasensitive chelating agent specifically designed for the detection of silver (I) in water, ensuring accuracy even without the presence of interfering ions. Additionally, it is applicable for the determination of copper (II).

Batrachotoxin (BTX), a potent neurotoxin and cardiotoxin, is found in the skin of the Colombian dart frog (Phyllobates aurotaenia). As an activator of sodium channels (sodium channel), it interferes with normal sodium channel closure by binding to voltage-gated sodium channels (sodium channel) on the cell membrane. This interaction causes a continuous influx of sodium ions into the cells, leading to persistent depolarization.
