Recently, we described the aminothiazole lead (4-biphenyl-4-ylthiazol-2-yl)-(6-methylpyridin-2-yl)-amine (1), which exhibits many desirable properties, including excellent stability in liver microsomes, oral bioavailability of ~40%, and high exposure in the brains of mice. Despite its good pharmacokinetic properties, compound 1 exhibited only modest potency in mouse neuroblastoma cells overexpressing the disease-causing prion protein PrPSc. Accordingly, we sought to identify analogues of 1 with improved antiprion potency in ScN2a-cl3 cells while retaining similar or superior properties. Herein we report the discovery of improved lead compounds such as (6-methylpyridin-2-yl)-[4-(4-pyridin-3-yl-phenyl)thiazol-2-yl]amine and cyclopropanecarboxylic acid (4-biphenylthiazol-2-yl)amide, which exhibit brain exposure/EC50 ratios at least tenfold greater than that of compound 1.

Compilation of agmatine structure and imidazoline moiety leads to a new group of imidazoline/α2-adrenoceptor ligands, 4(5)-(2-aminoethyl)imidazoline derivatives. In this study the exploration of previously unknown 4(5)-(2-aminoethyl)imidazolines including the analogues of reported imidazoline and α2-aderenoceptors ligands: clonidine, rilmenidine, idazoxan, efaroxan, antazoline, tracizoline is described. The synthesis of a variety of novel 4(5)-(2-aminoethyl)imidazolines and their I 1, I2, α2-adrenoceptors affinities are reported.
