乐活195产品是LOXO-195 is a potent and selective TRK (tropomyosin-related-kinase) inhibitor, with potential anticancer activity. LOXO-195 specifically targets and binds to TRK, including the fusion proteins containing sequences from neurotrophic tyrosine receptor kinase (NTRK) types 1 (NTRK1), 2 (NTRK2), and 3 (NTRK3). This prevents 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 and/or express NTRK fusion proteins.
