Neurotensin receptor 1 (NTR1) is a G protein coupled receptor that is widely expressed throughout the central nervous sys-tem where it acts as a neuromodulator. Neurotensin receptors have been implicated in a wide variety of CNS disorders but despite extensive efforts to develop small molecule ligands there are few reports of such compounds. Herein we describe the optimization of a quinazoline based lead to give 18 (SBI-553), a potent and brain penetrant NTR1 allosteric modulator.
