Design, synthesis and nootropic activity of new analogues of sunifiram and sapunifiram, two potent cognition-enhancers was written by Martini, Elisabetta;Salvicchi, Alberto;Ghelardini, Carla;Manetti, Dina;Dei, Silvia;Guandalini, Luca;Martelli, Cecilia;Melchiorre, Michele;Cellai, Cristina;Scapecchi, Serena;Teodori, Elisabetta;Romanelli, Maria Novella. And the article was included in Bioorganic & Medicinal Chemistry in 2009.Electric Literature of C7H14N2O This article mentions the following:
A series of amides and sulfonamides, structurally related to DM235 (sunifiram) and MN19 (sapunifiram), derived by ring expansion or contraction, or by inversion of the exocyclic amide function, have been synthesized and tested for cognition-enhancing activity in the mouse passive-avoidance test. Some of the compounds display good antiamnesic and procognitive activity, with higher potency than piracetam, and with a potency similar to the parent compounds In the experiment, the researchers used many compounds, for example, 1-(1,4-Diazepan-1-yl)ethanone (cas: 61903-11-5Electric Literature of C7H14N2O).
1-(1,4-Diazepan-1-yl)ethanone (cas: 61903-11-5) belongs to piperazine derivatives. Industrial applications of piperazine include the manufacture of plastics, resins, pesticides and brake fluids. Outside the body, piperazine has a remarkable power to dissolve uric acid and producing a soluble urate, but in clinical experience it has not proved equally successful.
