2-pyrrolidinone moiety is not critical for the cognition-enhancing activity of piracetam-like drugs

Farmaco. 2003 Sep;58(9):715-22. doi: 10.1016/S0014-827X(03)00111-3.

Abstract

Following the indications of previous work, 2-pyrrolidinone moiety of piracetam and piracetam-like compounds has been opened to the corresponding amide derivatives. As found previously in the case of 1,4-diazabicyclo[4.3.0]nonan-9-one compounds, the cognition-enhancing activity of 2-pyrrolidinone compounds is maintained in most cases, suggesting that this moiety is not crucial for activity.
