Summary
Phloridzin and phloretin were conjugated to gold nanoparticles (AuNPs) for enhanced anticancer drug delivery. This novel approach significantly increased the antineoplastic potency of both compounds against cancer cells.
Area of Science:
- Nanotechnology
- Materials Science
- Biochemistry
Background:
- Phloridzin, a dihydrochalcone from fruit trees, acts as an SGLT2 inhibitor with antidiabetic and antineoplastic properties.
- Phloretin, phloridzin's metabolite, shows weaker SGLT2 inhibition but enhanced anticancer activity.
- The study explores novel applications of these natural compounds in cancer therapy.
Purpose of the Study:
- To develop gold nanoparticle (AuNP)-mediated delivery systems for phloridzin and phloretin.
- To investigate the anticancer mechanisms of these conjugated dihydrochalcones.
- To enhance the therapeutic potential of phloridzin and phloretin through nanoparticle conjugation.
Main Methods:
- Synthesized phloridzin-AuNP (Phl-AuNP) and phloretin-AuNP (Pht-AuNP) using a rapid, single-step, biofriendly method.
- Characterized AuNP morphology and composition using TEM, UV-Vis spectroscopy, and SEM-EDS.
- Assessed antineoplastic activity against HeLa cancer cells via flow cytometry.
Main Results:
- Successfully synthesized stable Phl-AuNPs (15±5 nm) and Pht-AuNPs (8±3 nm).
- Demonstrated a significant increase in anticancer toxicity upon conjugation to AuNPs.
- Achieved a 4.49-fold increase in Phl-AuNP efficacy and a 17.45-fold increase in Pht-AuNP efficacy compared to their unconjugated forms.
Conclusions:
- Developed a simple, eco-friendly process for synthesizing stable AuNPs conjugated with dihydrochalcones.
- Phloridzin and phloretin conjugated AuNPs show significant potential as effective antineoplastic agents.
- This nanotechnology approach offers a promising strategy for enhancing cancer therapy.

25.4K
Fruits form from a mature flower ovary. As seeds develop from the ovules contained within, the ovary wall undergoes a series of complex changes to form fruit. In some fruits, such as soybeans, the ovary wall dries; in other fruits, such as grapes, it remains fleshy. In some cases, organs other than the ovary contribute to fruit formation; such fruits are called accessory fruits.

As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.

8.7K
Gene transcription is regulated by the synergistic action of several proteins that form a complex at a gene regulatory site. This is observed in eukaryotes, where the regulation of gene expression is a complex process. Regulatory proteins in eukaryotes can broadly be classified into two types – regulators that bind directly to specific DNA sequences and co-regulators that associate with regulatory proteins but cannot directly bind to the DNA. These co-regulators are further divided into...

02:45Functional Groups
89.4K
Functional groups are a group of atoms with characteristic properties, which when linked to the carbon skeleton of a molecule, alter the properties of that molecule. For example, the presence of certain functional groups on a molecule will make them hydrophilic, whereas others will make them hydrophobic. These functional groups are an indispensable part of organic chemistry and important components of biological molecules, such as carbohydrates, proteins, lipids, and nucleic acids. Each...

Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...

01:15Development of the Lymphatic System
2.2K
The development of lymphatic tissues and vessels in embryonic life begins around the fifth week. These structures originate from the mesoderm layer, with lymph sacs emerging from developing veins.
The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...
