Summary
Beta-cyclodextrins (βCDs) complexed with quercetin form ordered structures on DNA. These supramolecular complexes, stabilized by hydrogen bonds, offer insights into novel DNA-based drug delivery systems.
Area of Science:
- Biophysics
- Supramolecular Chemistry
- Nanotechnology
Background:
- Drug delivery systems utilizing supramolecular complexes with DNA are promising for intracellular transport.
- The molecular mechanisms of drug-carrier-DNA interactions are not well understood.
Purpose of the Study:
- To investigate the formation and adsorption of beta-cyclodextrin (βCD)-quercetin inclusion complexes on DNA.
- To elucidate the molecular mechanisms governing these supramolecular interactions.
Main Methods:
- Atomistic molecular mechanics and molecular dynamics simulations were employed.
- Analysis of inclusion complex formation, adsorption, and self-aggregation on DNA structure.
Main Results:
- βCD-quercetin inclusion complexes form ordered hydrophobic channels along DNA grooves.
- Hydrogen bonding between βCDs stabilizes a long-range, thread-like supramolecular structure enveloping the DNA.
- Intermolecular interactions drive the adhesion process.
Conclusions:

Polymeric carriers enhance targeted drug delivery by increasing efficacy while minimizing off-target effects. These carriers comprise a biodegradable polymeric backbone integrated with functional elements that enable targeting, improve physicochemical properties, and regulate drug release.Targeting MechanismsThe targeting ability of polymeric carriers is mediated by a homing device, which is a molecular recognition component designed to selectively bind to specific tissues or cells.

Rate-programmed drug delivery systems release drugs in a controlled manner to maintain therapeutic levels. Three main designs include reservoir, matrix, and hybrid systems.Reservoir systems consist of a drug core enclosed within a membrane that controls drug release. In non-swelling reservoir systems, polymers like ethyl cellulose or polymethacrylates are used. These do not hydrate in aqueous media and control release through membrane thickness, porosity, or insolubility. This type includes...

Clathrin-coated vesicles use endocytosis to transport receptors and lysosomal hydrolases from the Golgi to the lysosome in the late secretory pathway. Clathrin-mediated endocytosis was the first described endocytic process, and Clathrin-coated vesicles remain one of the most well-studied transport vesicles. The molecular machinery that generates clathrin-coated vesicles comprises over 50 proteins that precisely coordinate vesicle formation. Cell surface receptors concentrated in indented sites...

Body:Improving a drug's stability in the gastrointestinal (GI) tract is paramount for enhancing its bioavailability and therapeutic effectiveness. Various strategies are employed to protect the drug from the harsh gastric milieu and to ensure its release and absorption at the desired site within the GI tract.Polymer coatings are one such method used to shield drugs from the stomach's acidic environment. By preventing premature drug release, these coatings improve the bioavailability of unstable...

1.7K
Drugs must traverse multiple biological barriers, such as multi-layered skin, single-layered intestinal epithelium, and the plasma membrane, to reach their target sites within the body. The plasma membrane, a highly structured composite of phospholipids, carbohydrates, and proteins, is the cell's protective boundary, facilitating selective substance exchange.
Phospholipids arrange themselves into a bilayer, with hydrophilic heads oriented outward and hydrophobic tails facing inward.

Site-targeted drug delivery systems enhance therapeutic efficacy while minimizing systemic toxicity and treatment costs. Unlike conventional methods, these systems ensure precise drug delivery, improving bioavailability and reducing side effects. Targeted drug delivery is classified into three levels. First-order targeting directs drugs to the capillary beds of specific organs or tissues. Second-order targets specific cell types, such as tumor cells, using receptor-mediated interactions.
