p-SCN-Macropa
Based on 1 Customer Validation
p-SCN-Macropa is a bifunctional macrocyclic chelator featuring macrocyclic polyamine skeletons and thiocyanate (-SCN) reactive moieties. p-SCN-Macropa can conjugate with monoclonal antibodies including Nimotuzumab (HY-P9968), Rituximab (HY-P9913) and Trastuzumab (HY-P9907)-PEG6-DM1 for 225Ac radiolabeling to construct radioimmunoconjugates. p-SCN-Macropa is applicable for the research of colorectal cancer, HER2-positive breast cancer, TROP-2-positive cancers, and PSMA-positive cancers.

体外実験
p-SCN-macropa conjugates to Nimotuzumab (HY-P9968) and Rituximab (HY-P9913) with high purity, forming macropa-Nimotuzumab with an estimated 3 p-SCN-macropa molecules per antibody[1].
p-SCN-Macropa-derived[225Ac]Ac-macropa-Nimotuzumab potently inhibits viability of 2D monolayer cultures of DLD-1 (IC50 1.8 nM), SNU-C2B (IC50 3.3 nM), SW620 (IC50 4.6 nM), and HT-29 (IC50 10.1 nM) colorectal cancer cell lines[1].
p-SCN-Macropa-derived[225Ac]Ac-macropa-Nimotuzumab potently inhibits viability of 3D spheroids of DLD-1 (IC50 10.6 nM), SNU-C2B (IC50 14.7 nM), SW620 (IC50 19.5 nM), and HT-29 (IC50 41.5 nM) colorectal cancer cells[1].
p-SCN-macropa (1 MBq/300 μg; 7 days), as a bifunctional chelator in [225Ac]Ac-macropa-Trastuzumab (HY-P9907)-PEG6-DM1, supports high radiochemical purity and excellent in vitro stability in human serum and PBS[2].
p-SCN-macropa-based [225Ac]Ac-macropa-trastuzumab-PEG6-DM1 binds with high affinity to HCC1954 (KD = 36.98 nM) and JIMT-1 (KD = 20.16 nM) HER2-positive breast cancer cells, with HER2 density-dependent internalization that is significantly higher in high HER2-density HCC1954 cells[2].
p-SCN-Macropa (5-10 mg/mL; 90 min at 37°C for conjugation, 5-10 min at room temperature for radiolabeling)-conjugated rosigatamab efficiently chelates 225Ac at room temperature within 5-10 min[3].

体内実験
p-SCN-Macropa-based radioimmunoconjugate [225Ac]Ac-macropa-Nimotuzumab (13 kBq; i.v.) exhibits prominent long-term retention in liver and blood of healthy BALB/c mice, and displays preferential accumulation in DLD-1 colorectal tumor xenografts with a peak uptake of 32.0 % IA/g at day 5 post-administration[1].

Led partial tumor growth reduction in 4 mice, with tumor volumes 75, 57, 200, and 550.4 mm3 on day 90.
Extended median survival beyond 90 days, compared to 16 days for the control radioimmunoconjugate group and 12.5 days for the PBS group.\nInduced partial tumor growth response in 2 of 8 mice.
Extended median survival to 41 days, compared to 16 days for the control radioimmunoconjugate group and 24.5 days for the PBS group.
