Abstract:
Objective: Cutaneous T cell lymphoma (CTCL) is a kind of extranodal non-Hodgkin Tcell
lymphoma without healable treatment in the clinic. JAK2 amplification in CTCL patients
makes it a potential target for CTCL treatment. In the present study, we aimed to evaluate the anticancer
effect of ND-16, a novel nilotinib derivate, on CTCL cells and the underlying mechanism
targeting JAK2.
Methods and Results: We found that ND-16 was capable of regulating JAK2 and had a selective
inhibitory effect on CTCL H9 cells. The surface plasmon resonance and molecular docking study
indicated ND-16 bound to JAK2 with a high binding affinity. Further investigation revealed that
ND-16 inhibited the downstream cascades of JAK2, including STATs, PI3K/AKT/mTOR, and
MAPK pathways, followed by regulation of Bcl-2 family members and cell cycle proteins CDK/-
Cyclins. Flow cytometry analysis confirmed these results that ND-16-treated H9 cells showed cell
apoptosis and cell cycle arrest at S-phase.
Conclusion: ND-16 may be of value in a potential therapy for the management of CTCL.
