Definitions

  • the present invention belongs to the field of pharmaceutical chemistry, relates to the technical field of sulfonamide derivatives, and specifically relates to a sulfonamide compound as an anti-neuroblastoma agent, a preparation method and use thereof.
  • WDR5 WD40 repeat domain protein 5
  • WDR5 belongs to the WD40 protein family and is a protein containing a circular seven-blade ⁇ -propeller domain. WDR5 is highly conserved among different vertebrates, with a sequence identity of about 90%. WDR5 was first discovered to be involved in regulating osteoblast differentiation and promoting bone formation during skeletal development. In recent years, more and more studies have revealed the biological functions of WDR5, finding that it not only regulates biological behaviors such as cell proliferation, division, apoptosis, signal transduction, gene transcription, and DNA damage repair under physiological conditions, but is also highly correlated with the occurrence and development of a variety of tumors, making it a popular choice for tumor treatment targets.
  • WDR5 The most important function of WDR5 in vivo is epigenetic regulation. As a member of the histone methyltransferase (HMT) complex, it regulates histone methylation levels and activates the transcription of target genes. Abnormal WDR5 function can upregulate the expression of multiple tumor-promoting factors, activate tumor-related signaling pathways, and then enhance tumor cell proliferation, metastasis and drug resistance, driving the occurrence of epithelial-mesenchymal transition (EMT). WDR5 is also an auxiliary factor of myelocytoma viral oncogene homolog (Myc). As a transcription factor, Myc regulates the transcription of downstream genes by binding to the promoter region of the target gene.
  • Myc myelocytoma viral oncogene homolog
  • WDR5 is a key factor in the process of Myc-driven tumorigenesis. This mechanism has been confirmed in a variety of Myc-related tumors. In glioblastoma and neuroblastoma, WDR5 can promote the binding of Myc to the coactivator protein-associated arginine methyltransferase 1 (CARM1) promoter, enhancing the proliferation and self-renewal ability of tumor cells.
  • CARM1 coactivator protein-associated arginine methyltransferase 1
  • WDR5 co-localizes with N-Myc in the double minute homolog gene 2 (MDM2) promoter region, activates the transcription of MDM2, and inhibits the expression of tumor suppressor protein p53.
  • MDM2 double minute homolog gene 2
  • WDR5 maintains a high level of HIF-1 ⁇ in the body through epigenetic regulation, and also increases the expression of HIF-1 ⁇ through Myc in the transcription link, promoting the EMT, metastasis and invasion of tumor cells.
  • WBM WDR5 binding domain
  • WIN WDR5 interaction domain
  • the WBM site is a shallow and relatively hydrophobic binding pocket, mainly composed of Asn225, Tyr228, Leu240, Phe266, Val268 and Gln289.
  • Retinoblastoma binding protein 5 (RBBP5), C-myc, L-myc, N-myc, KAT8 regulatory NSL complex subunit 2 (KANSL2), etc. all interact with WDR5 through this site.
  • the WIN site is an arginine binding pocket, composed of amino acids such as Ala65, Ser91, Asp107, Phe133, Tyr191, Tyr260 and Phe263.
  • MML1-4 mixed lineage leukemia 1-4
  • KANSL1 KAT8-regulated NSL complex subunit 1
  • MBD3 methylphosphoguanosine phosphate binding protein
  • KIF2A kinesin heavy chain member 2A
