Description
(+)-Bicuculline, a light-sensitive competitive GABAA and GABAA-gated chloride channel antagonist, functions in the biochemical field as a drug, CNS stimulator, convulsant and neurotransmitter. Its chemical identities are alkaloid and phthalide-isoquinoline compound. Extracted from plant alkaloid in 1932, this metabolite has been definitively located in Adlumia fungosa, Dicentra cucullaria, Fumariaceae and some species of Corydalis. (+)-Bicuculline acts primarily on ionotropic GABAA receptors but also blocks Ca2+-activated potassium channels and can act as an agrochemical. As a poisonous neurotoxin, it affects nervous system responses associated with GABAA by binding to the receptors but not activating them, thus inhibiting the action of gamma-aminobutyric acid.

Description
1-Dodecylimidazole is grouped with the imidazole organic compounds, containing an imidazole 1,3-C3N2 ring produced by natural products like alkaloids. Imidazole is amphoteric and aromatic. When an additional carbon and two hydrogens bind to the ring of this compound, 1-Dodecylimidazole can produce a 1-dodecyl-3-methylimidazolium cation. As an antifungal, 1-Dodecylimidazole can inhibit sterol C14 demethylation at low levels, 2,3-oxidosqualene cyclization and subsequent transmethylation when the quantity is raised. This has been postulated as a result of its binding to sterol carrier proteins. It functions as a hypocholesterolaemic agent by inhibiting cholesterol biosynthesis at the level of 2,3-oxidosqualene sterol cyclase. This substance has been an View product page →

Like other thiopines, 2-Propylthiophene contains an aromatic and heterocyclic ring which has been used in pharmaceuticals and agrochemicals. 2-Propylthiophene appears in protein-based foods. It is considered a human metabolome for membranes, partially producing the scent of roast beef due to its heteroaromatic characteristics. Experiments have measured this substance in relation to Pd-catalysed direct arylation and gas chromatography-sulfur chemiluminescence detection to determine the processes of industrial catalysis.
