alkaloid

Camptothecin (CPT) belongs to the alkaloid group of natural products and is a specific DNA topoisomerase I (Topo I) inhibitor (IC50=679 nM) with specificity. Camptothecin has antitumor activity and induces apoptosis.

Arecoline hydrobromide (Arecoline HBr) is a muscarinic acetylcholine receptor agonist.

Norharmane (β-Carboline) is a natural β-carboline first isolated from plants of the Zygophyllaceae family.

Bicuculline ((+)-Bicuculline) is a light-sensitive competitive antagonist of GABAA receptors, originally identified in 1932 from plant alkaloid extracts, and isolated from Dicentra cucullaria, Adlumia fungosa, Fumariaceae, and various Corydalis species.

(+)-Magnoflorine (Thalictrin) has sedative and anxiolytic effects, probably mediated by Magnoflorine through a GABAergic mechanism of action. Magnoflorine and Sinomenine have protective effects, are mediated by some mechanism other than prevention of micelle formation or protection of the erythrocyte membrane against osmotic imbalance.

Galanthamine N-Oxide, an alkaloid extracted from Zephyranthes concolor bulbs, effectively inhibits acetylcholinesterase (AChE) from electric eel with an EC50 of 26.2 μM. It acts as a significant inhibitor of substrate accommodation within the active sites of Torpedo californica AChE (TcAChE), human AChE (hAChE), and human BChE (hBChE) enzymes.

Epi-galantamine, a diastereomer of galantamine, is an alkaloid extracted from the bulbs and flowers of the Caucasian snowdrop (Galanthus woronowii). It acts as an AChE inhibitor, featuring an EC50 of 45.7 μM.

Voacamine (Voacanginine) is an indole alkaloid. Voacamine exhibits potent cannabinoid CB1 receptor antagonistic activity. Voacamine also inhibits P-glycoprotein (P-gp) action in multidrug-resistant tumor cells.Voacanginine may have rhythmic effects.

Harmane (Loturine) is a bio-active β-Carboline and monoamine oxidase inhibitor found in coffee and tobacco smoke.

1. Thermopsine (Thermospine) exhibits antibacterial activity.

Myosmine is a minor tobacco alkaloid that is structurally related to nicotine.

Deserpidine (Harmonyl) is only found in individuals that have used or taken this drug. It is an ester alkaloid drug isolated from Rauwolfia canescens (family Apocynaceae) with antipsychotic and antihypertensive properties that has been used for the control of high blood pressure and for the relief of psychotic behavior.Deserpidine's mechanism of action is through inhibition of the ATP Mg2+ pump responsible for the sequestering of neurotransmitters into storage vesicles located in the presynaptic neuron. Deserpidine is a competitive angiotensin converting enzyme (ACE) inhibitor. Deserpidine also decreases angiotensin II-induced aldosterone secretion by the adrenal cortex.

Anisodamine Hydrobromide (6-Hydroxyhyoscyamine) is an anticholinergic and α1-adrenergic receptor antagonist used in the treatment of acute circulatory shock.

Vasicinone may act as a hepatoprotective agent. (±)-Vasicinone has significant antitussive, expectorant, and bronchodilating activities, which can be used to treat respiratory disease.(S)-Vasicinone exhibits antiproliferative activity against human gastric cancer cells MCG-803.

Guvacine ethyl ester (Arecoline) is an alkaloid found in betel nut that is used in the synthesis of GABA uptake inhibitors.

Laurolitsine ((+)-Norboldine), an alkaloid, is extracted from the leaves of Peumus boldus Molina.

Retrorsine selectively inhibits hepatocyte proliferation and following liver injury evokes small hepatocyte-like progenitor cells. Retrorsine can be used for the research of hepatocellular injury.

Robustine is a natural product, exhibits inhibitory potency against human phosphodiesterase 5 (hPDE5A) in vitro.

Alkaloid SN-f is a useful organic compound for research related to life sciences and the catalog number is T128485.

Cephaeline hydrochloride, a phenolic alkaloid found in Indian Ipecac, effectively inhibits the infection of viruses ZIKV and EBOV.

Palmatine chloride an isoquinoline alkaloid, is an important medicinal herbal extract with diverse pharmacological and biological properties.

Bocconoline is an alkaloid found in Bocconia cordata WILLD with potential anticancer activity for the study of Parkinson's disease (PD).

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.

Lamellarin D (Lamellarine D), a hexacyclic pyrrolizidine alkaloid isolated from marine invertebrates, is a mitochondria-targeted topoisomerase I inhibitor and a pro-apoptotic agent.
