Omberacetam is the nonproprietary name proposed for Noopept (see p.68, www.who.int/medicines/publications/druginformation/innlists/PL117.pdf?ua=1). Strictly speaking it does not belong to the racetam class of compounds (as it is a peptide). However, given its similarity it is often compared and categorized adjacent to other racetams.
On a purely pragmatic basis, I suggest we consider migrating Noopept to the racetam section. The INN may supplant the brand name in future but it's more important we set a standard in terms of naming conventions.
Update: PubChem now refers to Noopept as Omberacetam [ https://pubchem.ncbi.nlm.nih.gov/compound/Noopept ] Please see above regarding INN and re-categorizing Noopept into the racetam family on a pragmatic basis.
