SR 48692 is an orally bioavailable allosteric antagonist of the neurotensin receptor NTS₁ (K_d = 3.4 nM).^, SR 48692 inhibits high affinity neurotensin binding to brain tissue from guinea pig, newborn mouse, newborn human, and adult human as well as rat mesencephalic cells and HT-29 cells with IC₅₀ values ranging from 0.99 to 30.3 nM. It blocks neurotensin-induced intracellular calcium mobilization in HT-29 cells with a K_i value of 7.4 nM. SR 48692 (10 μM) inhibits NCI-H209 and NCI-H345 cell proliferation by approximately 70 and 80%, respectively. In vivo, SR 48692 (10 μg per day) reduces tumor volume and cell proliferation in an NCI-H209 mouse xenograft model. SR 48692 (80 μg/kg, p.o.) reduces contralateral turning induced by neurotensin (Item No. ) administration in mice by 85%. Daily administration of SR 48692 for five days in rats delays sensitization to the locomotor activating effects of cocaine during three additional cocaine challenges when given seven days prior to cocaine delivery but not under a cotreatment regimen.
