Chemical structure of 4-phenylpiperidine. Phenylpiperidines are chemical compounds with a phenyl moiety directly attached to piperidine. Of particular interest are a variety of derivatives of 4-phenylpiperidine, which have pharmacological effects including morphine-like activity [1] or other central nervous system effects.
4-Phenylpiperidine is a chemical compound. It features a benzene ring bound to a piperidine ring. 4-Phenylpiperidine is the base structure for a variety of opioids , such as pethidine (meperidine), ketobemidone , alvimopan , loperamide , and diphenoxylate .
Pyridine and poly(4-vinyl) pyridine have been shown to form conducting molecular wires with remarkable polyenimine structure on UV irradiation, a process which accounts for at least some of the visible light absorption by aged pyridine samples. These wires have been theoretically predicted to be both highly efficient electron donors and ...
MPTP (1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine) is an organic compound. It is classified as a tetrahydropyridine . It is of interest as a precursor to the monoaminergic neurotoxin MPP + , which causes permanent symptoms of Parkinson's disease by destroying dopaminergic neurons in the substantia nigra of the brain .
Butyrophenone is an organic compound with the formula C 6 H 5 C(O)C 3 H 7.It is a colorless liquid. The butyrophenone structure—a ketone flanked by a phenyl ring and a butyl chain—forms the basis for many other chemicals containing various substituents.
Piperidine is an organic compound with the molecular formula (CH 2) 5 NH. This heterocyclic amine consists of a six-membered ring containing five methylene bridges (–CH 2 –) and one amine bridge (–NH–).
MPP + (1-methyl-4-phenylpyridinium) is a positively charged organic molecule with the chemical formula C 12 H 12 N +. It is a monoaminergic neurotoxin that acts by interfering with oxidative phosphorylation in mitochondria by inhibiting complex I , leading to the depletion of ATP and eventual cell death .
In enzymology, the -norcoclaurine synthase (EC 4.2.1.78) is an enzyme that catalyzes a biological Pictect-Spengler synthesis: 1,2,3,4-Tetrahidroisoquinolines biosynthesis: in (S)-norcoclaurine synthase, the two substrates are 4-hydroxyphenylacetaldehyde and 4-(2-aminoethyl)benzene-1,2-diol, whereas its two products are (S)-norcoclaurine and H 2 O.
