Alkaloids Library

555 compounds

Alkaloids are a large and complex group of cyclic compounds that contain N. About 2,000 different alkaloids have been isolated. Important alkaloids include morphine, strychnine, atropine, colchicine, ephedrine, quinine, and nicotine. Alkaloids are useful as diet ingredients, supplements, and pharmaceuticals, in medicine and in other applications in human life. They showed anti-inflammatory, anticancer, analgesics, local anesthetic and pain relief, neuropharmacologic, antimicrobial, antifungal, and many other activities. Alkaloids are also important compounds in organic synthesis for searching new semisynthetic and synthetic compounds with possibly better biological activity than parent compounds.

MCE designs a unique collection of 555 alkaloids that all come from natural products. MCE Alkaloids Library is a useful tool for drug discovery that can be used for high throughput screening (HTS) and high content screening (HCS).

Acetylcholine-d4 chloride

Acetylcholine-d₄ (chloride) is the deuterium labeled Acetylcholine chloride. Acetylcholine chloride (ACh chloride), a neurotransmitter, is a potent cholinergic agonist. Acetylcholine chloride is a modulator of the activity of dopaminergic (DAergic) neurons through the stimulation of nicotinic acetylcholine receptors (nAChRs)[1][2]. Acetylcholine chloride inhibits p53 mutant peptide aggregation in vitro[5].

HY-B0282S1

Acetylcholine-d9 chloride

Acetylcholine-d₉ (chloride) is the deuterium labeled Acetylcholine chloride. Acetylcholine chloride (ACh chloride), a neurotransmitter, is a potent cholinergic agonist. Acetylcholine chloride is a modulator of the activity of dopaminergic (DAergic) neurons through the stimulation of nicotinic acetylcholine receptors (nAChRs)[1][2]. Acetylcholine chloride inhibits p53 mutant peptide aggregation in vitro[5].

HY-B1337S5

Choline-13C2 chloride
Choline- ¹³C₂ (chloride) is the ¹³C labeled Choline chloride[1]. Choline chloride is an essential nutrient that activates alpha7 nicotinic receptors and has analgesic and anti-inflammatory activity. Glycerophosphoinositol choline can affect diseases such as liver disease, atherosclerosis and neurological disorders[2][3].

HY-106901AS

Asoxime-d4 dichloride
Asoxime-d₄ (dichloride) is the deuterium labeled Asoxime dichloride. Asoxime dichloride (HI-6) is an antagonist to acetylcholine receptors (AChRs) including the nicotinic receptor, α7 nAChR. Asoxime dichloride involves in modulating immunity response. Asoxime dichloride (HI-6) can be used as an antigen and improves vaccination efficacy in the nervous system[1].

HY-N9484S

Menthofuran-13C2

Menthofuran- ¹³C₂ is ¹³C labeled Menthol (HY-N1369). Menthol is an analgesic and TRPM8 modulator. TRPM8 is a cold temperature sensing ion channel, and Menthol can regulate TRPM8 to exert analgesic and anti-irritation mechanisms. Menthol stimulates cold receptors and produces a cooling sensation by inhibiting Ca ⁺⁺ currents in neuronal cell membranes. Menthol also improves oral nicotine rejection in mice .

HY-A0009S

Galanthamine-d3 hydrobromide

Galanthamine-d₃ (hydrobromide) is deuterium labeled Galanthamine (hydrobromide). Galanthamine hydrobromide (Galantamine hydrobromide) is a selective, reversible, competitive, alkaloid AChE inhibitor, with an IC50 of 0.35 µM. Galanthamine hydrobromide is a potent allosteric potentiating ligand (APL) of human α3β4, α4β2, α6β4 nicotinic receptors ( nAChRs). Galanthamine hydrobromide is developed for the research of Alzheimer's disease (AD)[1][2][3].
