Valproic Acid (2-Propylpentanoic Acid) is an HDAC inhibitor that inhibits HDAC1 activity, induces HDAC2 degradation, and is orally active. Valproic Acid can be used in epilepsy and bipolar disorder research.

Thapsigargin is a natural product, an inhibitor of sarcoplasmic endoplasmic reticulum Ca2+ ATPase (SERCA) and an endoplasmic reticulum stress inducer. Thapsigargin increases cytoplasmic calcium concentration by blocking the ability of cells to pump calcium into the sarcoplasmic and endoplasmic reticulum.

Ionomycin is an calcium ionophore and an antibiotic that binds calcium ions (Ca2+). It is produced by the bacterium Streptomyces conglobatus.It is used in research to raise the intracellular calcium level (Ca2+) and as a research tool to understand Ca2+ transport across biological membranes. Ionomycin promotes apoptosis and induces the activation of protein kinase C (PKC).

Nigericin sodium salt is an antibiotic, an NLRP3 activator, and a cationic ion carrier. Nigericin sodium triggers the activation of the NALP3 inflammasome, which inhibits Golgi function and suppresses the growth of Gram-positive bacteria.

Capsaicin ((E)-Capsaicin) is a natural product extracted from Capsicum annuum, and is a TRPV1 agonist (EC50=0.29 μM). Capsaicin has antitumor, anti-inflammatory, antioxidant and neuroprotective activities.

Arachidonic acid (Immunocytophyte) is an unsaturated, essential fatty acid. It is found in animal and human fat as well as in the liver, brain, and glandular organs, and is a constituent of animal phosphatides. It is formed by the synthesis from dietary linoleic acid and is a precursor in the biosynthesis of prostaglandins, thromboxanes, and leukotrienes.

Hymenidin, an alkaloid isolated from the Okinawan sponge Hymeniacidon sp. is a 5-hydroxytryptaminergic receptor antagonist and voltage-gated potassium channel inhibitor with potential antiprotozoal effects.It selectively binds to FOXO1 DNA and reduces depolarization-induced elevation of cellular calcium.

Ionomycin calcium (SQ23377 calcium) is an effective and selective calcium ionophore, demonstrating high specificity for divalent cations (Ca>Mg>Sr=Ba).

Cyclic ADP-ribose (cADPR) is an effective calcium mobilization second messenger synthesized from NAD+ by ADP-ribosyl cyclase. It mainly increases cytosolic calcium through Ryanodine receptor-mediated endoplasmic reticulum release and extracellular influx via the opening of TRPM2 channels.

Tanshinone IIA sulfonate sodium (Tanshinone IIA sodium sulfonate) is a water-soluble derivative of tanshinone IIA extracted from Savia miltiorrhiza; a potent negative allosteric modulator of the human purinergic receptor P2X7. Tanshinone IIA sulfonate sodium (12.5 μM) inhibits hypoxia-induced PKG and PPAR-γ downregulation in PASMCs and distal pulmonary arteries of rats.

Taurocholic acid sodium salt hydrate (Sodium taurocholate hydrate), formed by the conjugation of taurine with cholic acid, is the primary ingredient in the bile of carnivorous animals. It acts as a detergent to solubilize fats for absorption and is employed as a cholagogue and choleretic.

Monensin sodium is an antiprotozoal agent produced by Streptomyces cinnamonensis.Monensin sodium salt (Monensin A sodium salt) causes a marked enlargement of the MVBs and regulates exosome secretion

L-Phenylalanine (3-Phenyl-L-alanine) is an essential amino acid and the precursor of the amino acid tyrosine, acts as an antagonist at α2δ calcium channels.

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.

Drotaverine hydrochloride is a type 4 cyclic nucleotide phosphodiesterase (PDE4) inhibitor,and is an antispasmodic drug, used to enhance cervical dilation during childbirth. Drotaverine hydrochloride is structurally related to papaverine

Urethane (Ethylurethane) was an antineoplastic agent .Now is used for other medicinal purposes.

1. Pulegone ((+)-Pulegone) has cytotoxicity followed by regenerative cell proliferation is the MOA for Pulegone-induced urothelial tumors in female rats. 2. Pulegone induces a verapamil-sensitive psychostimulant effect that appears to independ on the opening of L-type calcium channels. 3. Pulegone has negative reinforcing properties and seems to possess anxiolytic-like actions unrelated to the benzodiazepine site of the γ-aminobutyric acid type A (GABAA) receptor.

Acetylcholine Chloride is the chloride salt form of acetylcholine, a synthetic, quaternary amino alcohol with cholinergic properties. Acetylcholine chloride (Pilofrin) mimics the parasympathomimetic effect of the endogenous compound acetylcholine. Administered as an ophthalmic solution, this drug stimulates the cholinoceptors in the sphincter muscle of the iris, causing the pupil to constrict.

(-)-Epicatechin gallate ((-)-Epicatechin 3-O-gallate) is one of the catechin isomers and a potent antioxidant that can modulate a wide range of membrane proteins. Its bilayer-modifying potency was tested using gramicidin A (gA) channels as probes. All the catechins alter gA channel function and modify bilayer properties, with a 500-fold range in potency. The gallate group causes current block, as evident by brief downward current transitions.

Quinine dihydrochloride (Quinine bimuriate) is a primary alkaloid of various species of Cinchona (Rubiaceae). It is also an antimalarial and muscle relaxant (skeletal).

Cholesterol Myristate (Cholesteryl Myristate) is a natural steroid found in traditional Chinese medicine that interacts with various ion channels, including the GABAA receptor, nicotinic acetylcholine receptor, and the inward-rectifier potassium ion channel.

Quinidine hydrochloride monohydrate is an optical isomer of quinine, extracted from the bark of the Cinchona tree and similar plant species. It prolongs cellular action potential and decreases automaticity. This alkaloid dampens the excitability of cardiac and skeletal muscles by blocking sodium and potassium currents across cellular membranes. Quinidine also blocks muscarinic and alpha-adrenergic neurotransmission.
