Oxiracetam (developmental code name ISF 2522) is a nootropic drug of the racetam family and a very mild stimulant. [1] [2] Several studies suggest that the substance is safe even when high doses are consumed for a long period of time. [3] [4] [5] However, the mechanism of action of the racetam drug family is still a matter of research.
Some supposed nootropic substances are compounds and analogues of choline, a precursor of acetylcholine (a neurotransmitter) and phosphatidylcholine (a structural component of cell membranes). Alpha-GPC – L-alpha glycerylphosphorylcholine has been studied only in the context of cognitive performance alongside other substances such as caffeine.
Besides their potential medical use, modafinil analogues, including adrafinil, flmodafinil, fladrafinil, and modafiendz, are also sold online as substances that are believed to improve cognitive functions such as memory and focus (nootropics or "cognitive enhancers"). [1] [9] [10] [11]
2-Pyrrolidone Piracetam. Racetams, also sometimes known simply as pyrrolidones, [1] are a class of drugs that share a pyrrolidone nucleus. [2] [3] [4] Many, but not all, specifically have a 2-oxo-1-pyrrolidine acetamide nucleus.
