CHOLESTEROL LOWERING BILE-ACID BINDING-AGENTS - NOVEL LIPOPHILIC POLYAMINES

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-ethaediamine (23), are 29 and 24 times more potent than colestipol hydrochloride, respectively, for lowering animal serum cholesterol levels.
