Acute myeloid leukemia (AML) is a relatively common malignant hematological disease whose development is mostly associated with abnormal activation of the JAK/STAT3 signaling pathway. Our previous study revealed that SAR317461, a novel JAK2/STAT3 inhibitor, can effectively inhibit the activation of the JAK2/STAT3 signaling pathway and has significant damaging and pro-apoptotic effects on AML cell lines. This project aims to build upon our prior research to enhance the application of SAR317461 in AML. The surface modification of liposomes with the CD34 antibody, along with the inclusion of the SAR317461 and cytarabine (a common AML chemotherapeutic agent), is observed. Due to the high expression of CD34 on the surface of AML cells, the nanoliposome could target AML cells specifically, further achieving an effective treatment for AML through the synergistic effect of JAK2/STAT3 inhibitors and chemotherapeutic agents. The implementation of this project will provide more theoretical support and ideas for the clinical application of JAK/STAT3 inhibitors in malignant tumors and for overcoming chemotherapy resistance.
