Nilotinib-¹³C,d₃  (Synonyms: AMN107-¹³C,d₃)

Nilotinib-13C,d3 is a deuterated labeled Nilotinib^[1]. Nilotinib is an orally available Bcr-Abl tyrosine kinase inhibitor with antineoplastic activity.

Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs^[1].
Nilotinib (AMN107), selective Abl inhibitor, is designed to interact with the ATP-binding site of BCR-ABL with a higher affinity than imatinib while being significantly more potent compared with imatinib (IC₅₀<30 nM), also maintains activity against most of the BCR-ABL point mutants that confer Imatinib resistance^[2].
Nilotinib demonstrates significant antitumor efficacy against GIST xenograft lines and imatinib-resistant GIST cell lines which parent cell lines GK1C and GK3C shows imatinib sensitivity with IC₅₀ of 4.59±0.97 μM and 11.15±1.48 μM, respectively, imatinib-resistant cell lines GK1C-IR and GK3C-IR shows Imatinib resistance with IC₅₀ values of 11.74±0.17 μM (P<0.001) and 41.37±1.07 μM (P<0.001), respectively^[3].

Nilotinib (oral gavage, 40 mg/kg, daily, 4 weeks) shows equivalent or higher antitumor effects in BALB/cSLc-nu/nu mice with GIST xenograft^[3].
Nilotinib has a significant healing effect on the macroscopic and microscopic pathologic scores and ensures considerable mucosal healing in the indomethacin-induced enterocolitis rat model while decreases the PDGFR α and β levels and apoptotic scores in the colon^[4].
