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

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

L-Ascorbic acid (Vitamin C) is a natural product that is a potent reducing agent and antioxidant. L-Ascorbic acid functions in fighting bacterial infections, in detoxifying reactions, and in the formation of collagen. L-Ascorbic acid is used in the treatment of scurvy.

Dronedarone (SR 33589) is an amiodarone analogue which has an effective and promising treatment for Atrial fibrillation.

Urolithin C is a gut metabolite of ellagic acid. Urolithin C induces apoptosis in PC12 cells through a mitochondria-mediated pathway.

Ginsenoside Rd (Gypenoside VIII) may have properties that inhibit or prevent the growth of tumors.

Cyclopiazonic acid (CPA) is a neurotoxic secondary metabolite (SM) made by A. flavus. Cyclopiazonic acid (CPA) is an endoplasmic reticulum calcium ATPase (Ca2+ATPase; SERCA)nanomolar inhibitor and a potent inducer of cell death in plants.

Tetrandrine (Sinomenine A) is a naturally occurring biphenylisoquinoline alkaloid, a calcium channel inhibitor. Tetrandrine inhibits voltage-gated calcium channels (ICa) and Ca2+-activated potassium channels.

L-Ascorbic acid sodium salt (Vitamin C sodium salt) is a more bioavailable form of vitamin C that is an alternative to taking ascorbic acid as a supplement.

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.

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.

Psoralenoside is a natural product isolated from the fruits of Psoralea corylifolia, shows estrogen-like activity, osteoblastic proliferation accelerating activity, antitumor effects and antibacterial activity.

Halofuginone specifically inhibits collagen type I gene expression and matrix metalloproteinase 2 (MMP-2) gene expression, which may result in the suppression of angiogenesis, tumor stromal cell development, and tumor cell growth. Halofuginone Hydrobromide is the hydrobromide salt of halofuginone, a semisynthetic quinazolinone alkaloid anticoccidial derived from the plant Dichroa febrifuga, with antifibrotic and potential antineoplastic activities. These effects appear to be due to halofuginone-mediated inhibition of the collagen type I and MMP-2 promoters. Collagen type I and MMP-2 play important roles in fibroproliferative diseases.

1. Heteroclitin D can inhibit L-type calcium channels. 2. Heteroclitin D might be a valuable antitumor promoter or chemopreventor.

Catharanthine ((+)-3,4-Didehydrocoronaridine) suppresses nicotinic receptor-mediated diaphragm contractions with an IC50 of 59.6 μM.

Cycleanine has potent antibacterial, antifungal, antiplasmodial, and cytotoxic activities.

1. Praeruptorin C has been widely used as an antioxidant and a calcium antagonist to treat diseases. 2. Praeruptorin C partially protects cortical neurons by inhibiting the expression of GluN2B-containing NMDA receptors and regulating the Bcl-2 family. 3.

14-Deoxyandrographolide is a bioactive compound of Andrographis paniculata with hepatoprotective efficacy. It desensitizes hepatocytes to TNF-α-mediated apoptosis through the release of TNFRSF1A release.

Taurolithocholic acid sodium salt (Sodium taurolithocholate) is the major human metabolite, a bile acid which inhibits radioligand binding to muscarinic M1, but not to M2 or M3 receptors.

(+)-Kavain ((R)-KAWAIN) is one of the six major kavalactones found in the Piper methysticum (kava) plant; reversible inhibitor of MAO-B.

Gomisin J is a natural product and have vasodilatory activity. Gomisin J suppresses lipid accumulation by regulating the expression of lipogenic and lipolytic enzymes and inflammatory molecules through activation of AMPK, LKB1 and Ca2+ calmodulin-dependent protein kinase II and inhibition of fetuin-A in HepG2 cells.

Ginsenoside Ro (Chikusetsusaponin V) can reduce TXA2 production, weakly reduce COX-1 and TXAS activities, and has antiplatelet effects as a Ca2+ antagonist with an IC50 of 155 μM.

Myomodulin is a neuropeptide present in molluscs, insects, and gastropods. Within these organisms, myomodulin A specifically occurs in two identified Aplysia neurons: the ARC motor neuron [B16] and the abdominal neuron [L10].
