imine

[′i‚mēn]
(organic chemistry)
A class of compounds that are the product of condensation reactions of aldehydes or ketones with ammonia or amines; they have the NH radical attached to the carbon with the double bond, as R‒HC=NH; an example is benzaldimine.

This result is due to the contribution of less reactive imine groups of PANI component in the cure reaction of epoxy [51], As a result, when the grafted PANI in the filler increases, the concentration of the imine groups in the filler increases, and lead to higher [E.sub.a].
Irradiation of azomethine imine 1-4 O solutions in acetonitrile with light of [[lambda].sub.irr] 365 nm results in spectral changes in the characteristic of negative photochromism due to intramolecular photocyclization into diaziridines 1-4 C (Scheme 2), accompanied by a decrease in the intensity of long-wave absorption maxima and the appearance of absorption bands in the short-wave region of the spectrum [10, 30, 31] as shown in Figure 2(a) in the example of compound 1 and in Table 1.
This band is shifted to longer wavelength (lower wavenumber) in the range 1650-1634 [cm.sup.-1] of the complexes and confirms the coordination of the imine nitrogen to the metal ion.
The reaction of acetaldehyde with most amino acids generates relatively free and stable imines [10].

For diclofenac, several possible reactive intermediates have been postulated, including the 2,5- and 2,4'-quinone imines and both the parent and 4'-hydroxy-diclofenac acyl-glucuronides.
From chemical structure, we know that the carbonyl group (C=O) in some ketone or aldehyde-compounds is replaced by special functional groups, such as azomethine and/or imine group, to form series of special Schiff bases which are produced by the reaction of aldehydes or ketones with primary amines in the specific conditions [6, 7].
More recently, Imine et al [21] used both the 'lpc' method and a sliding mode observer method to estimate road profile with some success; Doumiati.
The main mechanism of acetaminophen-induced hepatotoxicity is an increase in oxidative stress and subsequent saturation of the glucuronidation and sulfation pathways of hepatic elimination, leading to more APAP being metabolized to N-acetyl-[rho]-benzoquinone imine (NAPQI).
