Neurobiology
Semax, Selank, and a literature written mostly in Russian
Two short synthetic peptides, one built from an ACTH fragment and one from the immunopeptide tuftsin, were studied for decades in Russian laboratories. Reading that work means reading what the assays measured, and where they stop.
Neurobiology
Neuropeptides: ACTH fragments, a sleep factor, and VIP
Three research lines from very different places: Soviet-era clinical pharmacology, a 1977 discovery that was never settled, and a well-mapped hormone.
