Summary
This study introduces switchable anion transporters using gold complexes. These transporters are activated by glutathione (GSH) in tumor cells, offering a targeted anti-cancer strategy.
Area of Science:
- Biochemistry
- Medicinal Chemistry
- Cancer Biology
Background:
- Anion transporters are investigated as potential anti-cancer agents.
- Disrupting cellular homeostasis and inducing cell death are key mechanisms.
- Targeted drug delivery remains a challenge in cancer therapy.
Purpose of the Study:
- To develop switchable anion transporters for targeted cancer therapy.
- To utilize gold complexes that are activated by specific tumor microenvironment conditions.
- To leverage the higher concentration of glutathione in tumors for selective drug activation.
Main Methods:
- Synthesis of gold complexes incorporating anion transporters.
- In situ activation of anion transport via gold decomplexation.
- Utilizing glutathione (GSH) as a trigger for transporter activation.
Main Results:
- Demonstrated switchable anion transport mediated by gold complexes.
- Achieved in situ activation of transporters upon addition of GSH.
- Showcased selective activation in the presence of elevated GSH levels, characteristic of tumor environments.
Conclusions:
- Gold complexes of anion transporters offer a novel strategy for targeted cancer therapy.
- The switchable nature, activated by GSH, allows for tumor-specific drug delivery and action.
- This approach holds promise for developing more effective and less toxic anti-cancer treatments.

7.4K
Mechanically-gated ion channels are proteins found in eukaryotic and prokaryotic cell membranes that open in response to mechanical stress. Tension, compression, swelling, and shear stress can alter the conformation of the protein, opening a transmembrane channel that allows the passage of ions for signal transmission. In eukaryotes, mechanically-gated channels are distributed in several regions like the neurons, lungs, skin, bladder, and heart, where they play critical roles in numerous...

1.8K
Active transport is a critical biological process that allows cells to move solutes against an electrochemical gradient. This process requires direct energy input and is characterized by its selectivity, saturability, and susceptibility to competitive inhibition.
Primary active transporters, like Na+, K+ and -ATPase, directly utilize ATP to move ions across the membrane. These transporters play significant roles in various physiological processes. For instance, Na+, K+ and -ATPase maintain...

One example of how cells use the energy contained in electrochemical gradients is demonstrated by glucose transport into cells. The ion vital to this process is sodium (Na+), which is typically present in higher concentrations extracellularly than in the cytosol. Such a concentration difference is due, in part, to the action of an enzyme "pump" embedded in the cellular membrane that actively expels Na+ from a cell. Importantly, as this pump contributes to the high concentration of...

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...

Transporters are essential membrane transport proteins with functions related to cell nutrition, homeostasis, communication, etc. Approximately 7% of all genes in the human genome code for transporters or transporter-related proteins.
Transporters are mainly composed of alpha-helices, built from bundles of ten or more helices traversing the plasma membrane. The solute-binding sites are located midway, where some of the helices are broken or distorted, making space for the binding site through...
