Flavins are important redox cofactors for enzymatic catalysis and therefore are central to a wide variety of processes, which include biosynthesis, electron transport, photosynthesis, and DNA repair. The wide range of processes catalyzed by flavins tends to make them promising prospects for synthetic catalysts. Their properties may also be relevant to organic electronic and optoelectronic gadgets, the place they possess the potential to serve as photoactive electron carriers, a really unusual residence in present photovoltaic methods.
In flavoenzymes, the flavin cofactor binds towards the lively web-site with the apoenzyme by noncovalent interactions. These interactions regulate cofactor recognition and tune the redox habits on the flavin cofactor.
On this Account, we describe the creation of host guest programs based on smaller molecule, polymer, and nanoparticle scaffolds that examine the purpose of aromatic stacking to the redox properties of your flavin and present insight into flavoenzyme function. We also describe the creation of synthetic flavin-based interlocked structures featuring aromatic stacking interactions, in conjunction with the use of aromatic stacking to direct self-assembly of flavin-based supplies.
The interplay concerning redox occasions and aromatic stacking interactions seen in these synthetic versions is vital for basic understanding of biological programs together with the flavoenzymes. The exact handle of aromatic interactions and binding of flavins not only underpins their biological activity but provides them the potential to become developed into novel natural optoelectronic products based on tuned synthetic flavin receptor assemblies.
In the broader context, the redox properties with the flavin present a very concise tool for looking at the role of electronics in aromatic stacking, an issue of common significance in biological and supramolecular chemistry."
"The approach of discovering by accomplishing has fueled supramolecular chemistry and, a lot more particularly, the comprehending of noncovalent aromatic interactions in synthetic and natural techniques. The preparation of new host molecules along with the investigation of their complexations have produced numerous insights into important noncovalent binding mechanisms. On this Account, we try to discuss significant binding contributions involving aromatic units and their practical applications.
We use typical examples from our group and also the literature, but this Account is not really a detailed see in the field.
Aside from systems with saturated frameworks, host compounds based on arenes offer improved controlled conformations and active interactions with a lot of guest molecules. Simply because of their fluorescent properties, larger aryl systems are especially suitable for sensors. The noncovalent interactions observed with different supramolecular complexes may be in contrast and exploited for interactions with biopolymers such as nucleic adds.
