hormone (TRH) mimetic: (4S,5S)‐5‐methyl‐N‐(2S)‐1‐[(2R)‐2‐methylpyrrolidin‐1‐yl]‐1‐oxo‐3‐(1,3‐thiazol‐4‐yl)propan‐2‐yl}‐2‐oxo‐1,3‐oxazolidine‐4‐carboxamide 1 (rovatirelin). The central nervous system (CNS) effect of rovatirelin after intravenous (iv) administration is 100‐fold higher than that of TRH. As 1 has four asymmetric carbons in its molecule, there are 16 stereoisomers. We synthesized and evaluated

A peptide derivation of the formula (I) or its pharmaceutically acceptable salt or hydrate thereof is disclosed.
These compounds have superior ability over thyroid stimulating hormone (TRH) and its derivatives to activate the central nervous system, such as, for example, sustained acetylcholine releasing action, anti-reserpine action and locomotor increment.
