Synthesis and biological studies of novel neurotensin(8-13) mimetics.


Novel neurotensin (NT) (8-13) (Arg(8)-Arg(9)-Pro(10)-Tyr(11)-Ile(12)-Leu(13)) mimetics 3, 4 were designed by adopting all intrinsic functional groups of the native neurotensin(8-13) and using a substituted indole as a template to mimic the pharmacophore of NT(8-13). Biological studies at subtype 1 of the NT receptor showed that 3 has a 55 and 580 nM binding… (More)
