Insights

A novel benzoylbenzohydrazide (1c) self-assembles into nanochannels, selectively transporting chloride ions to induce apoptosis in cancer cells. This artificial ion channel disrupts cellular homeostasis and autophagy, sparing noncancerous cells.

Area of Science:

  • Supramolecular chemistry
  • Cell biology
  • Cancer therapeutics

Background:

  • Synthetic ion transporters can cause cytotoxicity by disrupting ionic homeostasis.
  • The role of ion transporters in modulating autophagy is not well understood.

Purpose of the Study:

  • To investigate a novel benzoylbenzohydrazide (1c) as a selective chloride ion transporter for cancer therapy.
  • To explore the mechanism of 1c-induced cancer cell death, focusing on ion homeostasis and autophagy.

Main Methods:

  • Self-assembly of benzoylbenzohydrazide (1c) into supramolecular nanochannels.
  • Assessment of chloride ion transport across cell membranes.
  • Evaluation of cytotoxicity in cancer and noncancerous cells.
  • Analysis of lysosomal deacidification and autophagy disruption.

Main Results:

  • Compound 1c self-assembles into nanochannels for selective chloride ion transport.
  • 1c disrupts ionic homeostasis and induces apoptosis specifically in cancer cells.
  • 1c causes lysosomal deacidification, leading to autophagy disruption in cancer cells.
  • 1c exhibits minimal toxicity towards noncancerous cells.

Conclusions:

  • Benzoylbenzohydrazide (1c) functions as a cancer-selective artificial ion channel.
  • 1c induces apoptosis in cancer cells by disrupting ionic homeostasis and autophagy.
  • This study presents a novel strategy for cancer treatment using targeted ion transport.

Autophagic Cell Death01:18

Autophagic Cell Death

Christian de Duve discovered “autophagy,” a process in which cellular components are engulfed by membrane-bound organelles called autophagosomes. The autophagosomes then fuse with lysosomes to digest the enclosed contents. Autophagy is generally activated in cells to prevent cell death. However, cell death is triggered when the damage is beyond repair.
Autophagy and Apoptosis
Autophagy can activate apoptosis. In normal conditions, the autophagy activating protein Beclin-1 and...

The Intrinsic Apoptotic Pathway01:31

The Intrinsic Apoptotic Pathway

Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...

Voltage-gated Ion Channels01:26

Voltage-gated Ion Channels

Voltage-gated ion channels are transmembrane proteins that open and close in response to changes in the membrane potential. They are present on the membranes of all electrically excitable cells such as neurons, heart, and muscle cells.
Generally, all voltage-gated ion channels have a 'voltage-sensing domain' that spans the lipid bilayer. The charged residues in the sensor move in response to the membrane potential changes that open the channel allowing ions movement. There are several...

Ligand-gated Ion Channels01:19

Ligand-gated Ion Channels

Ligand-gated ion channels are transmembrane proteins with a channel for ions to pass through and a binding site for a ligand. The channel opens only when a ligand attaches to the binding site.
Three Subfamilies of Ligand-gated Ion Channels
Ligand-gated ion channels fall into three subfamilies. The 'Cys-loop' includes the nicotinic acetylcholine receptors, γ-aminobutyric acid (GABA), glycine, and 5-hydroxytryptamine receptors. The second one is the 'Pore-loop' channels that...

Electron Transport Chain: Complex I and II01:46

Electron Transport Chain: Complex I and II

The mitochondrial electron transport chain (ETC) is the main energy generation system in the eukaryotic cells. However, mitochondria also produce cytotoxic reactive oxygen species (ROS) due to the large electron flow during oxidative phosphorylation. While Complex I is one of the primary sources of superoxide radicals, ROS production by Complex II is uncommon and may only be observed in cancer cells with mutated complexes.
ROS generation is regulated and maintained at moderate levels necessary...

Ligand-Gated Ion Channel Receptor: Gating Mechanism01:30

Ligand-Gated Ion Channel Receptor: Gating Mechanism

Ligand-gated ion channels are transmembrane proteins that play a vital role in intercellular communication and functions of the nervous system. They allow the influx of ions across the membrane once the neurotransmitter binds, allowing the subsequent transmission of electrical excitation across the neurons. Other ligand-gated ion channels, like the γ-aminobutyric acid (GABA) receptor, permit anions like chloride into the cells on the binding of the GABA molecule. Their entry into the cell...
