Agonist Comments
The sequence of neurotensin is identical for all mammalian species.

Neurotensin and neuromedin N are synthesised from a common precursor [24].

Neurotensin and [125I]neurotensin bind with high affinity to NTS1 from all species 79-84.

[125I]-Trp11-neurotensin is specific for murine NTS1 receptors and exhibits low affinity for NTS1 receptors of human or other species [46,57].

[125I]-azidobenzoyl-neurotensin(2-13) is a photoreactive and radioactive analogue for covalent labelling of neurotensin receptors (including NTS1) from any species [15-16].

Xenopsin and contulakin-G are natural analogues of neurotensin from Xenopus laevis [5] and Conus geographus resepctively [20].

[α-bodipy]neurotensin(2-13) is a fluorescent synthetic analogue of neurotensin [7].

KH28, ABS212 and ABS-201 are able to cross the blood-brain barrier. ABS-201 and ABS212 are stable bioavailable NT analogues.

Antagonist Comments
SR142948A binds to both NTS1 and NTS2 with similar nanomolar affinities.

SR48692 has a 10-30 times higher affinity for NTS1 than for NTS2 [35,42].
