Insights

Dual inhibitors targeting ErbB1 and ErbB2 show promise in cancer therapy. Computational analysis identified potent FDA-approved drugs and Neuropep peptides with significant binding affinity for these tyrosine kinases.

Area of Science:

  • Oncology
  • Pharmacology
  • Computational Biology

Background:

  • ErbB1 and ErbB2 are key targets in cancer drug discovery.
  • Developing dual inhibitors is crucial for effective cancer therapy.

Purpose of the Study:

  • To identify potential dual inhibitors of ErbB1 and ErbB2 tyrosine kinases.
  • To evaluate FDA-approved drugs and Neuropep peptides for anticancer activity.

Main Methods:

  • In silico molecular docking using Cytoscape, iGEMDOCK, and HPEPDOCK.
  • Binding energy analysis with DataWarrior software.
  • In vitro MTT anticancer assay for IC50 determination.

Main Results:

  • Eleven FDA-approved drugs and eleven Neuropep peptides exhibited strong 2D interactions and binding energy with ErbB1 and ErbB2.
  • Peptide YSFGL and doxorubicin demonstrated significant IC50 values against A549 and MDA-MB-231 cancer cell lines.
  • Results were compared to the standard drug lapatinib.

Conclusions:

  • Identified FDA-approved drugs and Neuropep peptides as potential dual inhibitors of ErbB1/ErbB2.
  • Peptide YSFGL and doxorubicin show promising in vitro anticancer activity.
  • Computational methods are valuable for discovering novel cancer therapeutics.

Mitogens and the Cell Cycle

Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Transducer Mechanism: Enzyme-Linked Receptors

Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.
Major types that are helpful drug targets include:

Chemotherapy-Induced Nausea and Vomiting: Neurokinin-1 Receptor Antagonists

Neurokinin 1 (NK1) receptors are distributed across the GI tract, vagal afferents, and key CNS regions including the central vomiting center and chemoreceptor trigger zone (CTZ) Chemotherapy agents stimulate enterochromaffin cells in the gastrointestinal (GI) tract to release large amounts of substance P (SP). SP is a neuropeptide released by specific sensory nerves in response to many different stressors, including those in the GI mucosa affected by chemotherapy.  SP binds and activates...

Combination Therapies and Personalized Medicine02:50

Combination Therapies and Personalized Medicine

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...
