Is PNB-0408 the same as dihexa?

Yes. PNB-0408 is the development code listed as an alias on this site's dihexa profile. It names the same angiotensin IV analogue, molecular weight about 564 daltons. This site's review found no human trial, and the 2013 introduction paper carries an Expression of Concern. The code is a laboratory label, not a counted cognitive result and not an approval.
