Abstract

A series of 2-oxopiperazine, 4-aminomethyl-, 3-amino-and 3-aminomethylpiperidine analogues of DM235 (sunifiram) and MN19 (sapunifiram), two previously reported potent cognition-enhancers, have been synthesized and tested in the mouse passive-avoidance test. The compounds display minimal effective doses in the range 0.3–10mg/kg. Although the new substances do not show improved activity when compared to the parent ...
