This method was extended to other kind of organic amine including ethylenediamine, diaminopropane, butylamine and tetradecylamine.
Different primary amines were used; isopropylamine, benzylamine and aniline, with the latter aromatic amine included to illustrate the effect of conjugation of the maleimide with an aromatic ring.
Naturally occurring amines include the alkaloids, which are present in certain plants; the catecholamine neurotransmitters (i.e., dopamine, epinephrine, and norepinephrine); and a local chemical mediator, histamine, that occurs in most animal tissues.
Conjugation of a wide range of structurally different amines including the amines with enhanced biological activity were studied in detail.
Different amines include aliphatic amines such as primary, secondary, tertiary and cyclic amines as well as aromatic amines and hetero arenes containing nitrogen heteroatom.
The amines included crystalline and non-crystalline block poly(oxyethylene oxypropylene)amines of average molecular weight (Mw) from 1000 to 8000.
The reaction that we designed is applicable to the trifluoroacetylation of a wide variety of amines, including amines with stereogenic centers, which underwent trifluoroacetylation without racemization.
The root mean square (rms) deviation is 18 K for different classes of amines including 133 diverse compounds.
In the present work, 18-crown-6 ether (18C6) is utilized to bind specifically to various protonated primary amines, including the protonated side chain of lysine.
Biogenic amines including putrescine, histamine, cadaverine, and tyramine were selected for study based on the number of nitrogen groups in their structure.
