[D-Trp11]-Neurotensin, an analogue of Neurotensin (NT), is a selective antagonist of NT in perfused rat hearts but behaves as a full agonist in guinea pig atria and rat stomach strips. [D-Trp11]-Neurotensin can inhibit NT-induced hypotension[1][2].

In Vitro	[D-Trp11]-Neurotensin (0.13-1.1 μM) markedly inhibits NT-induced coronary vessel constriction in perfused rat hearts[1]. [D-Trp11]-Neurotensin (2-110 μM) exhibits NT-like activity in perfused rat hearts[1].
In Vivo	[D-Trp11]-Neurotensin (50-500 nmol/kg; i.v.) has hypotensive activity in pentobarbital-anesthetized rats, with an ED25 of 122 nmol/kg[2].
