JMV 7490
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.

[68Ga]Ga-JMV 7490 (0.1-500 nM; incubated at 4°C for 2 hours) binds to NTS1 on HT-29 cells, with a Kd of 14.61 nM and an NTS1/NTS2 selectivity of 44.4; [111In]In-JMV 7490 has a Kd of 77.47 nM against NTS1 and a selectivity of 6.5[1].
[68Ga]Ga-JMV 7490 exhibits complete ex vivo stability in human plasma, while [111In]In-JMV 7490 retains only 76% and 61% of intact peptide after 2 h and 4 h of ex vivo incubation, respectively[1].
