SR 48692 is a neurotensin antagonist; selective for NTS1 over NTS2 (apparent affinity, Ke, is 36 nM for NTS1). Competitively inhibits binding of [125I]-neurotensin to HT29 and N1E115 cell membranes (IC50 values are 15.3 and 20.4 nM respectively).

NTRC-824 (Compound 5) is a potent, selective and neurotensin-like nonpeptide neurotensin receptor type 2 (NTS2) antagonist with an IC50 of 38 nM and a Ki of 202 nM. NTRC-824 is >150-fold selectivity for NTS2 over NTS1 (Ki >30 μM).

JMV 449 is a potent neurotensin receptor agonist. JMV 449 shows an IC50 of 0.5 nM in binding to mouse brain membranes and an EC50 of 1.9 nM in contracting the guinea-pig ileum. JMV 449 has highly potent and long-lasting hypothermic and analgesic effects in the mouse.

[Lys8, Lys9]-Neurotensin (8-13) (JMV438), a Neurotensin analog, exerts its analgesic effects through activation of the G protein-coupled receptors NTS1 and NTS2, with Ki values of 0.33 nM and 0.95 nM for hNTS1 and hNTS2 receptors, respectively.

[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.

SORT-PGRN interaction inhibitor 1 is a potent inhibitor of the sortilin-progranulin interaction with an IC50 of 2 μM.
