Is demethylation an oxidation?
Definition: The process of removing one or more methyl groups from a molecule, involving the oxidation (i.e. electron loss) of one or more atoms in the substrate.

What is oxidative Dealkylation?
O-dealkylation: In the first step, the enzyme removes a hydrogen atom from the carbon adjacent to the oxygen (Hydrogen atom transfer, HAT), to generate a neutral carbon radical. Hydroxyl recombination follows in the second step to form a hemiacetal intermediate.
What is the effect of Conine in insect?
Abstract. Toxicity of coniine, an alkaloid of Conium maculatum (poison hemlock), is manifested by characteristic nicotinic clinical signs including excitement, depression, hypermetria, seizures, opisthotonos via postsynaptic nicotinic receptors.
How was coniine discovered?
Coniine was first isolated from poison hemlock in 1826 by Giseke [18]. Its structure was established in 1881 by Hofmann [19] and soon thereafter, in 1886, it was synthesized by Ladenburg [20], thus making it the first alkaloid to be structurally characterized and chemically synthesized.
What is N-Dealkylation?
N-dealkylation is a commonly observed metabolic reaction for drugs containing secondary and tertiary amines. On searching the literature, it is obvious that this reaction is far less common among cytochrome P450 2D6 catalyzed reactions compared with other cytochromes P450.
What is the significance of the Dealkylation process?
N-Dealkylation is a frequently encountered metabolic reaction. It is often responsible for the production of the major metabolite obtained from an N-alkyl containing drug.
