Definitions

  • the present invention relates to novel pomalidomide derivatives and methods for their preparation.
  • Thalidomide was a drug sold from the late 1950s to the 1960s to prevent morning sickness in pregnant women, but as teratogenic side effects were reported, its use and handling was prohibited for pregnant women, as well as people of childbearing age or those likely to become pregnant (Lancet) .2004 May 29;363(9423):1802-11). However, interest in the drug increased again after thalidomide was found to be clinically effective in the treatment of erythema nodosum (ENL), HIV wasting syndrome, and various cancers.
  • ENL erythema nodosum
  • Anti-tumor necrosis factor alpha activity was confirmed from mechanistic studies on ENL activity. Specifically, thalidomide increases the degradation of TNF- ⁇ RNA, thereby reducing its synthesis and secretion. Further studies have shown that it is a known co-stimulator of both CD8+ and CD4+ T cells and may also act as an angiogenesis inhibitor as an inhibitor of basic fibroblast growth factor (bFGF), vascular endothelial growth factor (VEGF) and the transcription factor NF ⁇ B. It turns out.
  • bFGF basic fibroblast growth factor
  • VEGF vascular endothelial growth factor
  • TNF- ⁇ and its family members play a pivotal role in various physiological and pathological processes, including cell proliferation and differentiation, apoptosis, regulation of immune responses, and induction of inflammation.
  • TNF- ⁇ acts through two receptors, TNFR1 and 2, the former of which is expressed in all tissues and is the main signaling receptor for TNF- ⁇ . The latter is mainly expressed in immune cells and mediates more limited biological responses.
  • the caspase cascade can be activated, leading to cell death through apoptosis.
  • the main cell surface molecules that can initiate apoptosis are the ligands and receptors of TNF family members.
  • each death-inducing member of the TNF receptor family contains a cytoplasmic 'death domain' (DD), a protein-protein interaction motif that is important for binding to downstream components of the signaling machinery.
  • DD cytoplasmic 'death domain'
  • TRAIL a tumor necrosis factor-related apoptosis-inducing ligand
  • TRAIL a tumor necrosis factor-related apoptosis-inducing ligand

  • the combined treatment of lenalidomide and dexamethasone is known to be quite effective, with a disease-free survival of 13.4 months and an overall survival of 38 months.
  • Pomalidomide directly inhibits angiogenesis and myeloma cell growth, and this dual effect is centered on its activity in myeloma rather than on other pathways such as TNF- ⁇ inhibition.
