Substance Name: Larotrectinib [USAN:INN]
RN: 1223403-58-4
UNII: PF9462I9HX
InChIKey: NYNZQNWKBKUAII-KBXCAEBGSA-N
Notes
- A TRK kinase inhibitor.
- NCI: Trk inhibitor LOXO-101 An orally available, tropomyosin receptor kinase (Trk) inhibitor, with potential antineoplastic activity. Upon administration, LOXO-101 binds to Trk, thereby preventing neurotrophin-Trk interaction and Trk activation, which results in both the induction of cellular apoptosis and the inhibition of cell growth in tumors that overexpress Trk. Trk, a receptor tyrosine kinase activated by neurotrophins, is mutated in a variety of cancer cell types and plays an important role in tumor cell growth and survival. (NCI Thesaurus)
