NTR1 Modulator

SBI-553 is a potent and brain penetrant NTR1 allosteric modulator, with an EC₅₀ of 0.34 μM.

DOTA-NT-20.3-IPBA is a Neurotensin receptor 1 (NTR1)-targeting albumin binder with specific high-affinity binding to NTR1. DOTA-NT-20.3-IPBA is formed by the conjugation of DOTA-NT-20.3 and IPBA. DOTA-NT-20.3-IPBA can be used for positron emission tomography (PET) imaging following labeling with [⁶⁸Ga]Ga.

JMV 7490 is a highly potent and highly hydrophilic neurotensin receptor NTS₁ probe that can be successfully labeled with ⁶⁸Ga and ¹¹¹In. JMV 7490 acts as an efflux inhibitor to reduce its efflux in NTS₁-positive cancer cells; it also serves as an internalization inducer and is efficiently and continuously internalized by NTS₁-positive cancer cells. ¹¹¹In-radiolabeled JMV 7490 shows persistent uptake in NTS₁-positive xenografts in nude mice, but no significant uptake in NTS₁-negative xenografts. JMV 7490 can be used for in vivo tracer applications of NTS1-positive tumors and supports related research on colorectal cancer.
