DPI-4452
Based on 1 Customer Validation
DPI-4452 is a CAIX-targeting cyclic peptide with a DOTA cage, and can be chelated with radionuclide for CAIX-expressing tumor PET-CT imaging and study. DPI-4452 specifically and selectively binds CAIX without interaction with an in vitro off-target receptor panel of 55 targets (IC50 for recombinant hCAIX: 130 nM). Radiolabeled DPI-4452 inhibits tumor growth in HT-29 and SK-RC-52 xenograft mouse models. DPI-4452 can be used for the synthesis/research of Radionuclide-Drug Conjugates (RDCs).

hCA IX 0.25 nM (Kd) |
DPI-4452 (with or without chelating lutetium or gallium ions) binds potently and specifically to CAIX with minimal internalization without interaction with an in vitro off-target receptor panel of 55 targets[1].
DPI-4452 (111In-labeled, 8 h) has a similar affinity for Chinese hamster ovary cells expressing hCAIX and cCAIX, markedly higher than that of Chinese hamster ovary cells expressing mCAIX (KD: 0.3 and 63 nM, respectively)[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
DPI-4452 ([177Lu]Lu-labeled, single doses of 100 MBq or 3 once-weekly 33 MBq doses, i.v.) reduces tumor burden in HT-29 and SK-RC-52 human xenograft mouse models[1].
DPI-4452 ([111In]In-labeled, 30 MBq, i.v.) exhibits high tumor uptake in the HT-29 CRC and SK-RC-52 ccRCC xenograft tumor mouse models[1].
DPI-4452 mass dose (2.5-22.5 μg/kg) does not affect uptake in healthy tissues in the tested dose range in Beagle dogs[1].
