Description

Technical Field

[0001] This invention relates to a class of small molecule protein-degrading drugs, optical isomers, or pharmaceutically acceptable salts that can degrade the transcription factor STAT3, and as pharmaceutical treatments for hyperproliferative diseases such as cancer. Background Technology

[0002] The JAK-STAT signaling pathway is an important tumor-associated signaling pathway. After cytokine receptors, hormone receptors, or growth factor receptors on the cell surface bind to their corresponding ligands, intracellular JAK kinases are activated, thereby inducing phosphorylation of the downstream transcription factor STAT and the formation of homodimers. These homodimers then enter the cell nucleus and initiate or inhibit the transcription of a series of tumor-associated genes.

[0003] Transcription factor STAT regulates various tumor-associated genes, such as cMyc, Survivin, BCL-XL, VEGF, HIF, and NF-κB. Mutations in STAT gain-of-function are common in tumor cells, leading to overactivation of the pathway. This overactivation results in increased tumor cell proliferation and survival, abnormal angiogenesis, tumor cell invasion and migration, tumor immune escape, and maintenance of tumor stem cell-like structures.

[0004] In addition, recent studies have found a close relationship between STAT3 and the suppressive immune microenvironment of tumor tissues. Overactivation of STAT in dendritic cells (DCs) leads to a decrease in the expression of MHC type II molecules and co-stimulatory factors, thereby reducing their antigen presentation and T cell activation capabilities. Expression in neutrophils, NK cells, and effector T cells reduces their ability to recognize, activate, and kill tumor cells. Simultaneously, it can promote M2 polarization of tumor-associated macrophages, the maturation and expansion of myeloid-derived suppressor cells, induce T cell differentiation into regulatory T cells, and increase PD-L1 expression in tumor cells and the aforementioned immunosuppressive cells, thereby forming a suppressive immune microenvironment and promoting tumor immune escape.

[0005] In summary, the JAK-STAT signaling pathway can promote tumor proliferation through multiple pathways, and therefore is a potential target for anti-tumor drug development.

[0006] Although several small-molecule STAT3 inhibitors have been reported in recent years, none have yet received market approval due to their poor efficacy. Therefore, there is an urgent need to develop a new generation of potent STAT3 inhibitors.

[0007] Significant progress has been made in targeted protein degradation technology (PROTAC) in recent years. This technology achieves target protein degradation by inducing ubiquitination. Drugs using this technology do not need to continuously occupy the target protein; the catalytic concentration is sufficient to achieve target degradation. Therefore, developing targeted degradation molecules against STAT3 holds promise for overcoming the insufficient efficacy of current small-molecule STAT3 inhibitors. Summary of the Invention:

Sodium borohydride (2.19 g, 57.55 mmol, 1.4 equiv) was added in portions. The reaction mixture was stirred at -10 °C for 1 hour, and the reaction was monitored by TLC until completion. Water (80 mL) was slowly added to the reaction mixture at 0 °C, and after stirring for about half an hour, the mixture was extracted with EA (100 mL × 3). The extract was washed with saturated brine (100 mL), dried over anhydrous sodium sulfate, filtered, and the filtrate was concentrated and dried to give 1-(tert-butyl)-2-methyl(2S)-5-hydroxypyrrolidine-1,2-dicarboxylate (8.9 g, 36.28 mmol, yield 88.2%).

The organic phase was washed with saturated brine (60 mL), dried over anhydrous sodium sulfate, filtered, and the filtrate was concentrated. The crude product was subjected to column chromatography (PE:EA = 10:1, v / v) to give 1-(tert-butyl)-2-methyl(2S)-5-allylpyrrolidine-1,2-dicarboxylate (5.3 g, 19.68 mmol, yield: 51%). LC-MS: (ESI) [M+H] + =270.2. 1 H NMR: (400MHz, CDCl3): δ5.86–5.72(m,1H),5.11–5.02(m,2H),4.37–4.19(m,1H),4.00–3.81(m,1H),3.74–3 .71(m,3H),2.76–2.53(m,1H),2.26–2.14(m,2H),2.01–1.89(m,2H),1.81–1.71(m,1H),1.47–1.40(m,9H).

The reaction solution was cooled to -78 °C, and ozone was bubbled through the reaction solution until it turned light blue. The ozone bubbling was then stopped. TLC analysis showed the disappearance of the starting material and the formation of new spots. Air was bubbled into the reaction solution to remove excess ozone, and triethylamine (7.46 g, 73.78 mmol, 21 equiv) was added at -78 °C.
