Insights

Researchers developed a novel inhibitor, BAS01025917, targeting human epidermal growth factor receptor (HER) family proteins for cancer therapy. This potential pan-HER inhibitor shows promise for treating non-small cell lung cancer (NSCLC) with improved properties.

Area of Science:

  • Oncology
  • Medicinal Chemistry
  • Computational Biology

Background:

  • The ErbB receptor family plays a crucial role in various human cancers, including non-small cell lung cancer (NSCLC).
  • Targeting ErbB receptors is a key therapeutic strategy, necessitating the development of novel inhibitors.

Purpose of the Study:

  • To design and identify a novel inhibitor targeting the human epidermal growth factor receptor (HER) family.
  • To discover a potential pan-HER inhibitor with favorable pharmaceutical properties and broad antitumor activity.

Main Methods:

  • Development of a five-point pharmacophore model based on known HER inhibitors.
  • Virtual screening of over 468,000 compounds from ZINC, ASINEX, and DrugBank databases.
  • Docking analysis, ADME property evaluation, and molecular dynamic simulations were employed to identify and validate lead compounds.

Main Results:

  • A novel hit molecule, BAS01025917, was identified with superior glide scores and pharmaceutically relevant properties compared to afatinib.
  • BAS01025917 demonstrated potential for increased central nervous system (CNS) involvement and broad-spectrum antitumor activity.
  • Molecular dynamic simulations validated the inhibitory potential of the lead compound.

Conclusions:

  • BAS01025917 represents a promising novel scaffold for developing a low-toxicity, potent pan-HER inhibitor.
  • Further investigation of BAS01025917 could lead to advanced therapeutic options for HER-driven cancers like NSCLC.

Ligand Binding Sites

Proteins are dynamic macromolecules that carry out a wide variety of essential processes; however, the activities of most proteins depend on their interactions with other molecules or ions, known as ligands.
Protein-ligand interactions are quite specific; even though numerous potential ligands surround a cellular protein at any given time, only a particular ligand can bind to that protein. Moreover, a ligand binds only to a dedicated area on the surface of the protein, known as the...

Ligand Binding and Linkage00:49

Ligand Binding and Linkage

Allosteric proteins have more than one ligand binding site; the binding of a ligand to any of these sites influences the binding of ligands to the other sites. When a protein is allosteric, its binding sites are called coupled or linked.  In the case of enzymes, the site that binds to the substrate is known as the active site and the other site is known as the regulatory site. When a ligand binds to the regulatory site, this leads to conformational changes in the protein that can influence...

Metal-Ligand Bonds

The hemoglobin in the blood, the chlorophyll in green plants, vitamin B-12, and the catalyst used in the manufacture of polyethylene all contain coordination compounds. Ions of the metals, especially the transition metals, are likely to form complexes.
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...

Persuasion Strategies

Researchers have tested many persuasion strategies, including the foot-in-the door and the door-in-the-face techniques, in a variety of contexts. Ultimately, the principles are effective in selling products and changing people’s attitude, ideas, and behaviors (Cialdini & Goldstein, 2004).
