Abstract:
A series of novel lipophilic polyamines was synthesized by the sodium cyanoborohydride-mediated reductive amination of various ketones and aldehydes with the polyamine tris(2-aminoethyl)amine. Two of these compounds, N,N-bis[2-(cyclododecylamino)ethyl]-N'-benzyl-1,2-ethanediamine trihydrochloride (36.3HCl) and N,N-bis[2-(cyclododecylmethylamino)ethyl]-N',N'-dimethyl-1,2-ethan ediamine (23), are 29 and 24 times more potent than colestipol hydrochloride, respectively, for lowering animal serum cholesterol levels.

Indirect-Acting Cholinergic Agonists: Mechanism of Action
Reversible inhibitors like edrophonium bind to a specific part of the enzyme called the anionic catalytic site. They form noncovalent bonds, which means they are not strongly attached to the enzyme. This creates a temporary and less stable enzyme–inhibitor complex, leading to...
