Summary
Researchers developed alkyl group-modified trimesic amide molecules (TAs) for anion transport. TA6 demonstrates superior perchlorate transport, showing the best activity and selectivity reported to date.
Area of Science:
- Supramolecular Chemistry
- Membrane Transport
- Anion Recognition
Background:
- Anion transport across biological membranes is crucial for cellular function.
- Developing efficient and selective synthetic anion transporters remains a significant challenge.
- Trimesic amide derivatives offer a promising scaffold for anion binding and transport.
Purpose of the Study:
- To synthesize and evaluate a series of alkyl group-modified trimesic amide molecules (TAs) for anion transport.
- To identify specific molecular modifications that enhance anion transport activity and selectivity.
- To characterize the transport efficiency and selectivity of the most promising TA derivatives.
Main Methods:
- Synthesis of alkyl group-modified trimesic amide molecules.
- Anion transport assays using vesicle models to determine EC50 values.
- Selectivity studies comparing transport rates for different anions.
- Structure-activity relationship analysis to correlate molecular modifications with transport performance.
Main Results:
- A series of TAs were synthesized and tested for anion transport capabilities.
- TA6 exhibited the highest ion transport activity and selectivity among the tested compounds.
- TA6 efficiently transported anions in the order ClO4- > I- > NO3- > Br- > Cl-.
- TA6 demonstrated a low EC50 value of 17.6 nM for perchlorate transport, outperforming other anions significantly.
Conclusions:
- Alkyl group modification of trimesic amides can lead to highly effective anion transporters.
- TA6 represents a new benchmark in synthetic perchlorate transporters due to its exceptional activity and selectivity.
- These findings open avenues for developing advanced materials for anion separation and sensing applications.

418
Carrier-mediated transport is a pivotal process in drug absorption, particularly for lipid-insoluble drugs, and encompasses facilitated diffusion and active transport. Facilitated diffusion allows drugs to move along their concentration gradient without energy expenditure, while active transport utilizes ATP to drive drug movement against this gradient.
Active transport involves two types of membrane-spanning transporters: uptake and efflux. Uptake transporters are expressed in the small...

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...

4.3K
ATP-binding cassette or ABC transporter is the largest superfamily of integral membrane proteins. The transporters have transmembrane-binding domains (TMDs) and nucleotide-binding domains (NBDs). The TMDs are specific to their substrates, whereas the NBDs are similar to engines that complete ATP hydrolysis to complete the substrate transport. They can be full transporters consisting of two TMDs and NBDs, half transporters with one TMD and NBD, while some encoded with a single TMD or NBD are...

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...

The plasma membrane, a critical structure in cellular biology, houses an array of transporters, or carrier proteins, interspersed within its lipid bilayer. These proteins play a crucial role in solute transport through facilitated diffusion, a form of passive diffusion that uses transporters to move the molecules across the membrane.
In this process, substrates such as organic compounds and ions interact with a transporter on one side, triggering conformational changes in proteins that enable...

2.7K
ATP-binding cassette or ABC transporters are a class of ATP-driven pumps that hydrolyze ATP to move solutes across the membrane. They can be grouped into importers and exporters. While exporters are present in all domains of life, importers exist only in bacteria and some plants.
In bacteria, based on the number of transmembrane helices and the chemical nature of their substrates, the ABC importers can be divided into three types:
