Thevetin B is a cardiac glycoside and an inhibitor of Na+-, K+-dependent adenosinetriphosphatase (Na+,K+-ATPase) from Thevetia peruviana.

Ecdysone is a major steroid hormone in insects and herbs. Ecdysone triggers mineralocorticoid receptor activation and induces cellular apoptosis. Ecdysone signaling through Ecdysone receptor isoform B1 is required cell autonomously for the muscle death.

Paederosidic acid methyl ester has antinociception, is possibly related to the pathway of NO-cGMP-ATP sensitive K(+) channels.

Reserpine (Serpalan) is an alkaloid found in the roots of Rauwolfia serpentina and R. vomitoria. Reserpine inhibits the uptake of norepinephrine into storage vesicles resulting in depletion of catecholamines and serotonin from central and peripheral axon terminals. It has been used as an antihypertensive and an antipsychotic as well as a research tool, but its adverse effects limit its clinical use.

20(S)-Ginsenoside Rg3 (Rg3) possess an ability to inhibit the lung metastasis of tumor cells via inhibition of the adhesion and invasion of tumor cells. It inhibits the proliferation of human umbilical vein endothelial cells(HUVEC) and has anti-angiogenesis activities.

Quinidine is a stereoisomer of the antimalarial agent quinine and a class Ia antiarrhythmic agent. for the treatment of abnormal heart rhythms and also malaria.

Eucalyptol, a natural monoterpenoid and cyclic ether found in eucalyptus species, effectively controls excessive airway mucus secretion and asthma by inhibiting pro-inflammatory cytokines. It serves as an efficacious treatment for non-purulent sinusitis, reducing inflammation and pain when applied topically, and demonstrating leukemic cell-killing capabilities in vitro.

Chlorahololide D is a natural lindane-type sesquiterpene dimer and selective potassium channel blocker that stimulates reactive oxygen species ROS levels to cause cell cycle arrest in the G2 phase, modulates Bcl-2 and Bax and FAK, thereby inhibiting MCF-7 cell growth and triggering apoptosis. Chlorahololide D inhibits tumor proliferation, migration and angiogenesis in in vivo experiments and has anti-breast cancer potential.

Cicutoxin is a convulsant compound. It inhibits Na+ and K+ channels and suppresses the γ-aminobutyric acid pathway. As a potent GABA antagonist, Cicutoxin induces recurrent seizures and exhibits cholinergic activity. Its primary targets are the brain and skeletal muscles. Cicutoxin can be isolated from [Cicuta maculata] and [Cicuta douglasii].

2,2,2-Trichloroethanol, the active form of the sedative hypnotic drug chloral hydrate, is an agonist for the nonclassical K2P channels TREK-1 (KCNK2) and TRAAK (KCNK4). It activates a nonclassical potassium channel in cerebrovascular smooth muscle and dilates the middle cerebral artery [1]. [1]. Nikhil K Parelkar, et al. 2,2,2-trichloroethanol Activates a Nonclassical Potassium Channel in Cerebrovascular Smooth Muscle and Dilates the Middle Cerebral Artery. J Pharmacol Exp Ther. 2010 Mar;332(3):803-10.

Quinine sulfate dihydrate plays a major role in potassium channel blockers. It is also used as an antimalarial, anticholinergic, antihypertensive and a hypoglycemic agent. It inhibits mitochondrial ATP-regulated potassium channel. It is also used to study the metabolism of biocrystalized heme, hemozoin, in malarial parasites and to study the toxicity of heme (FP)-complexes.

Ifenprodil is a selective NMDA receptor (glutamate) antagonist.

Quinine is a natural cinchona alkaloid that has been used for centuries in the prevention and therapy of malaria. Quinine is also used for idiopathic muscle cramps. Quinine therapy has been associated with rare instances of hypersensitivity reactions which can be accompanied by hepatitis and mild jaundice.

Quinine hydrochloride dihydrate (Quinine HCl Dihydrate) is a white crystalline K+ channel blocker, used to treat malaria.

Novobiocin Sodium (Albamycinsodium) binds to DNA gyrase and blocks adenosine triphosphatase (ATPase) activity. Novobiocin sodium is an antibiotic compound derived from Streptomyces niveus. It has a chemical structure similar to coumarin.

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.

(±)-Naringenin (Naringenine) is a natural product. It displays vasorelaxant effect on endothelium-denuded vessels via the activation of BKCa channels in myocytes.

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.
