Summary
Natural polyphenols enhance sanshool properties by creating nanoparticles (NPs). These NPs show improved biocompatibility and reduced skin damage in animal models, offering a novel strategy for natural active molecules.
Area of Science:
- Biomaterials Science
- Natural Product Chemistry
- Dermatology
Background:
- Naturally occurring active molecules often have limitations like instability and toxicity.
- Sanshool, derived from Zanthoxylum xanthoxylum, exhibits such limitations hindering its applications.
- Natural polyphenols offer potential for improving the properties of active molecules.
Purpose of the Study:
- To enhance the properties of sanshool using natural polyphenol-based nanoparticles (NPs).
- To evaluate the efficacy of these sanshool-loaded NPs in reducing skin damage and improving biocompatibility.
- To establish a novel strategy for improving naturally occurring active molecules.
Main Methods:
- Fabrication of sanshool-loaded nanoparticles using natural polyphenols.
- Intracellular evaluation of nanoparticle efficacy.
- In vivo animal model studies to assess skin photodamage and related parameters.
Main Results:
- Prepared sanshool NPs demonstrated decreased photodamage score and skin-fold thickness compared to naked sanshool.
- Enhanced biocompatibility, improved free radical scavenging, and reduced apoptosis ratios were observed.
- Significant reduction in DNA double-strand breaks was noted with the NP formulation.
Conclusions:
- Natural polyphenol-based nanoparticles effectively boost the key properties of sanshool.
- This strategy offers a promising approach to overcome the limitations of natural active molecules for therapeutic applications.
- The developed NPs show potential for dermatological applications due to reduced skin damage and improved safety profile.

3.0K
In the presence of oxidizing agents, phenols are oxidized to quinones. Quinones can be easily reduced back to phenols using mild reducing agents. The electron-donating hydroxyl group enhances the reactivity of the aromatic ring, enabling oxidation of the ring even in the absence of an α hydrogen.
o-hydroxy phenols are oxidized to o-quinones and p-hydroxy phenols to p-quinones. Such redox reactions involve the transfer of two electrons and two protons. The reversible redox...

2.4K
The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...
