Description

Technical Field

[0001] This invention belongs to the field of pharmaceutical technology, specifically relating to a STAT3 inhibitor, its preparation method, pharmaceutical composition, and its uses. Background Technology

[0002] Signal transducer and activator of transcription 3 (STAT3) is aberrantly upregulated and activated in various cancers, including pancreatic cancer. It can regulate tumor cell proliferation, differentiation, apoptosis, and angiogenesis, thus serving as a promising target for anticancer therapy. STAT3 is transiently activated under physiological conditions but exhibits persistent activation in many cancers. Two amino acid residues of STAT3, Tyr705 and Ser727, are phosphorylated upon activation. Phosphorylation at the Tyr705 site of STAT3 (p-Tyr705) mediates the classical activation pathway of STAT3. Upon stimulation by cytokines or growth factors, Janus-activated kinase (JAK), Src kinase, and epidermal growth factor receptor (EGFR) can phosphorylate the Tyr705 residue of STAT3, further promoting STAT3 dimerization via the Srchomology 2 (SH2) domain. Subsequently, the STAT3 dimer is translocated to the nucleus to initiate downstream gene transcription. Unlike Tyr705 phosphorylation, phosphorylation of STAT3 at Ser727 (p-Ser727) mediates a non-canonical activation pathway for STAT3. Following phosphorylation by serine kinase mitogen-activated protein kinase (MAPK), extracellular regulatory protein kinases (ERK1 / 2), c-Jun N-terminal kinase (JNK), and p38, p-Ser727 enters the mitochondria via its interaction with GRIM-19 to regulate mitochondrial oxidative phosphorylation (OXPHOS). Mitochondrial STAT3 p-Ser727 enhances the activity of electron transport chain complexes (ETCs), leading to increased ATP production and oxygen consumption in cancer cells. Simultaneously, phosphorylation at STAT3 Ser727 also maximizes Tyr705 phosphorylation-mediated STAT3 transcriptional activity through interactions with other transcriptional cofactors. Notably, the synergistic effect of STAT3 phosphorylation at Tyr705 and Ser727 is essential for complete STAT3 activation, which promotes the formation and development of various cancers. Studies have shown that blocking Tyr705 phosphorylation-mediated aberrant STAT3 activation or blocking Ser727 phosphorylation can inhibit the proliferation and migration of pancreatic cancer cells. Furthermore, mounting evidence suggests that some pancreatic cells exhibit metabolic dependence on the OXPHOS pathway. For example, OXPHOS inhibitors targeting complex I, IACS-010759 and BAY87-224327, have entered clinical trials for the treatment of advanced pancreatic cancer, indicating that OXPHOS inhibition is emerging as a novel strategy for pancreatic cancer treatment. However, the clinical application of these OXPHOS inhibitors that directly target complex I is limited due to their toxicity.Therefore, inhibiting STAT3 Ser727 phosphorylation to indirectly block OXPHOS may be an alternative treatment strategy. Furthermore, some clinical studies have shown that high expression of p-Tyr705 and p-Ser727 is closely associated with poor prognosis in pancreatic cancer patients. Therefore, simultaneously blocking STAT3 Tyr705 and Ser727 phosphorylation may be a promising treatment strategy for pancreatic cancer. Summary of the Invention

[0204] Compound solution and FGFR4 kinase solution were added to a 384-well assay plate, mixed thoroughly, and incubated at room temperature for 30 minutes. Substrate reaction solution was then added, and the reaction mixture was incubated at room temperature for 60 minutes. An equal volume of assay solution was then added, mixed thoroughly, and incubated at room temperature. After 60 minutes, the enzyme reaction was terminated with EDTA, and Envision assays were performed to obtain FGFR4 activity (the group without FGFR4 protein served as a negative control, and the group with FGFR4 protein but without the compound served as a positive control). The IC50 of the compound was calculated using software.
