Abstract

Insights

The development of protein kinase CK2 (Casein kinase 2) modulators, particularly inhibitors, has seen a significant surge in patent filings since 2004. This reflects growing interest in CK2 inhibitors for potential therapeutic applications.

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Pharmacology

Background:

  • Protein kinase CK2 (Casein kinase 2) is a crucial enzyme involved in numerous cellular processes.
  • Dysregulation of CK2 activity is implicated in various diseases, including cancer, inflammation, and autoimmune disorders.
  • While CK2 inhibitors have been explored for years, only CX-4945 has advanced to Phase II clinical trials.

Purpose of the Study:

  • To review the historical development of CK2 activity modulators.
  • To analyze the timeline of patent registrations for CK2 modulators.
  • To highlight the recent increase in patent activity for CK2 inhibitors.

Main Methods:

  • Literature review focusing on patent databases.
  • Chronological analysis of patent filings related to CK2 modulators.
  • Identification of trends in CK2 inhibitor development.

Main Results:

  • CK2 was discovered in 1954, but the first patent for its modulators appeared in 2004.
  • A notable increase in patent applications for CK2 inhibitors has occurred in the last five years.
  • This trend indicates a renewed focus on developing CK2-targeted therapies.

Conclusions:

  • The patent landscape reveals a delayed but accelerating interest in CK2 modulators.
  • The recent surge in patents underscores the therapeutic potential of CK2 inhibitors.
  • Further research and development in this area are anticipated.

Protein Kinases and Phosphatases

Proteins undergo chemical modifications that trigger changes in the charge, structure, and conformation of the proteins. Phosphorylation, acetylation, glycosylation, nitrosylation, ubiquitination, lipidation, methylation, and proteolysis are various protein modifications that regulate protein activity. Such modifications are usually enzyme-driven.

Many proteins in the cell are regulated by phosphorylation, the addition of a phosphate group. A family of enzymes called kinases...

Inhibition of Cdk Activity02:34

Inhibition of Cdk Activity

The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...

M-Cdk Drives Transition Into Mitosis

Checkpoints throughout the cell cycle serve as safeguards and gatekeepers, allowing the cell cycle to progress in favorable conditions and slow or halt it in problematic ones. This regulation is known as the cell cycle control system.
Cyclin-dependent kinases, or Cdks, work in concert with cyclins to control cell cycle transitions. M-Cdk, a complex of Cdk1 bound to M cyclin, is a well-known example of this coordinated control that drives the transition from the G2 to the M phase.

MAPK Signaling Cascades01:07

MAPK Signaling Cascades

Mitogen-activated protein kinase, or MAPK pathway, activates three sequential kinases to regulate cellular responses such as proliferation, differentiation, survival, and apoptosis. The canonical MAPK pathway starts with a mitogen or growth factor binding to an RTK. The activated RTKs stimulate Ras, which recruits Raf or MAP3 Kinase (MAPKKK), the first kinase of the MAPK signaling cascade. Raf further phosphorylates and activates MEK or MAP2 Kinases (MAPKK), which in turn phosphorylates MAP...
