NCS-MP-NODA
NCS-MP-NODA (NODA-Bz-SCN) is a NODA-derived bifunctional chelator. NCS-MP-NODA can conjugate with biomolecules including the RGD tripeptide, and is used for aluminum-[18F] fluoride-based positron emission tomography (PET) radiolabeling. NCS-MP-NODA can conjugate with the free lysine amino group of the PD-L1-specific peptide DK221 to generate DK222, which can be radiolabeled with 18F to form [18F]DK222. NCS-MP-NODA can be used in studies related to triple-negative breast cancer, melanoma and colon cancer.

NCS-MP-NODA conjugates to the free lysine amine of DK221 under room temperature conditions to form DK222, a peptide suitable for radiofluorination[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
The tracer [18F]DK222 (7.4 MBq; intravenous injection; single dose), synthesized from NCS-MP-NODA, shows extremely low uptake in SUM149 breast cancer xenografts with low PD-L1 expression, which is 88% lower than that in MDAMB231 tumors with high PD-L1 expression[3].
The tracer [18F]DK222 (7.4 MBq; intravenous injection; single dose), synthesized from NCS-MP-NODA, exhibits high specific uptake in PD-L1-overexpressing LOX-IMVI melanoma xenografts; its uptake is significantly reduced after administration of a blocking dose of DK221 (intravenous injection; single dose) prior to [18F]DK222 injection[3].

Animal Model:NSG (nonobese, diabetic, severe-combined immunodeficient gamma; 5- to 6-wk-old; male or female; orthotopic implantation of 2 × 10^6 MDAMB231 human triple-negative breast cancer cells)[3]
-
Dosage:[18F]DK222: ~200 μCi (7.4 MBq); blocking dose of DK221: 50 mg/kg
-
Administration:i.v.; single dose; blocking dose given 30 min prior to [18F]DK222 injection
-
Result:Showed high accumulation in MDAMB231 tumors as early as 15 min, with tumor uptake remaining consistently high for 4 h after injection.
Reached a tumor-to-blood ratio of 4.5 and tumor-to-muscle ratio of 30.0 at 60 min.
Reduced tumor uptake by 79% (P < 0.0001) in mice receiving the blocking dose of DK221.
