Matrine is an alkaloid found in plants from the Sophora genus. It has a variety of pharmacological effects, including anti-cancer effects, as well as κ-opioid and μ-opioid receptor agonism. Matrine possesses strong antitumor activities in vitro and in vivo.
Bulbocapnine (632-47-3, 298-45-3)
Bulbocapnine is an alkaloid found in Corydalis (Papaveraceae) and Dicentra, plants in the family Fumariaceae that can cause fatal poisoning in sheep and cattle. It has been shown to act as an acetylcholinesterase inhibitor, and inhibits biosynthesis of dopamine via inhibition of the enzyme tyrosine hydroxylase. According to the Dorlands Medical Dictionary, it "inhibits the reflex and motor activities of striated muscle.
2-METHYLNAPHTHALENE (7419-61-6, 91-57-6)
2-methylnaphthalene, methyl-13C-labeled · 2-methylnaphthalene, lithium salt, ion(1-) · 2-methylnaphthalene, naphthalene-1-(13)C-labeled
2-Methylnaphthalene is a polycyclic aromatic hydrocarbon (PAH). On February 22, 2014, NASA announced a greatly upgraded database for detecting and monitoring PAHs, including 2-methylnaphthalene, in the universe. According to NASA scientists, over 20% of the carbon in the universe may be associated with PAHs, possible starting materials for the formation of life.
Biphenyl (92-52-4, 68409-73-4)
diphenyl · diphenyl, 14C-labeled
Biphenyl (or diphenyl or phenylbenzene or 1,1′-biphenyl or lemonene) is an organic compound that forms colorless crystals. Particularly in older literature, compounds containing the functional group consisting of biphenyl less one hydrogen (the site at which it is attached) may use the prefixes xenyl or diphenylyl. It has a distinctively pleasant smell.
1-METHYLNAPHTHALENE (90-12-0, 1321-94-4)
1-Methylnaphthalene is a polycyclic aromatic hydrocarbon (PAH). It has a cetane number of zero, and was previously used as the lower reference for cetane number. However, due to the expense and handling difficulty of 1-methylnaphthalene, it was replaced in this capacity by isocetane, with a CN of 15.
