1. Hyaluronic acid-butyrate conjugates for barrier restoration in atopic dermatitis: CD44-mediated retention and inflammation-responsive release.
Hyaluronic acid–butyrate conjugates, especially 5 k-HAB, enhanced dermal retention 6.47-fold versus free butyrate via CD44-mediated targeting and CES2-triggered release. In DNFB-induced atopic dermatitis mice, 5 k-HAB improved barrier function and inflammation with superior effects on keratinocyte proliferation, oxidative stress, barrier proteins, and cytokines compared to HA, free butyrate, or higher-MW conjugates.
Impact: This study introduces a disease-responsive conjugate platform that couples skin targeting with on-site release, addressing a key bottleneck in topical therapy—local retention. It provides a rational framework for translating dermal treatments in inflammatory skin diseases.
Clinical Implications: While preclinical, the HAB design suggests a pathway to more durable, targeted topical treatments for atopic dermatitis and possibly other inflammatory dermatoses, potentially reducing reliance on steroids and improving adherence.
Key Findings
- 5 k-HAB increased skin retention 6.47-fold vs. free butyrate and improved penetration in IVPT using normal and AD-like skin.
- Mechanism: CD44 overexpression enabled HA-mediated targeting; elevated CES2 activity triggered local butyrate release.
- In DNFB-induced AD mice, 5 k-HAB accelerated lesion resolution, lowered TEWL and erythema, restored hydration, and normalized epidermal structure.
- 5 k-HAB outperformed HA, free butyrate, and higher-MW conjugates in promoting keratinocyte proliferation, reducing oxidative stress, upregulating barrier proteins, and suppressing inflammatory cytokines.
Methodological Strengths
- Multi-system evaluation: IVPT in normal and AD-like skin plus an in vivo DNFB mouse model
- Mechanistic validation of targeting (CD44) and release (CES2) with head-to-head comparisons across molecular weights
Limitations
- Preclinical only; no human clinical data or long-term safety assessment
- Comparisons to standard-of-care AD therapies (e.g., topical corticosteroids) were not included
Future Directions: Conduct ex vivo human skin and early-phase clinical studies to confirm targeting and efficacy; optimize conjugate molecular weight and dosing; evaluate long-term safety and combinatorial regimens with current AD therapies.
2. Ginsenoside-based nanoliposomes co-delivering ergothioneine and coenzyme Q10 to combat skin aging via mitochondrial modulation.
ECG-Lipo co-delivers ergothioneine and CoQ10 using ginsenoside-based liposomes to enhance skin penetration and restore mitochondrial function in oxidative stress-challenged fibroblasts. Molecular docking supports PPTGM interaction with OCTN-1, offering a mechanistic basis for improved transport and mitochondrial protection.
Impact: Demonstrates a mitochondria-focused, dual-ingredient nanocarrier that addresses delivery barriers for anti-aging actives and links carrier composition to transporter interactions.
Clinical Implications: Provides a translational platform for cosmeceutical or therapeutic formulations targeting mitochondrial dysfunction in skin aging; warrants safety, irritation, and efficacy testing in humans.
Key Findings
- ECG-Lipo formed uniform, stable, high-encapsulation unilamellar vesicles using DPPC and PPTGM via flash nanoprecipitation.
- Enhanced skin penetration and cellular repair vs. free drugs by Franz diffusion assays, in vivo mouse skin imaging, and fibroblast migration assays.
- Molecular docking suggests PPTGM interacts more strongly with OCTN-1 than cholesterol, supporting improved EGT transport.
- In stressed human dermal fibroblasts, ECG-Lipo preserved mitochondrial morphology, restored membrane potential, and reduced mitochondrial superoxide.
Methodological Strengths
- Integrated in vitro, in vivo imaging, and computational docking to triangulate efficacy and mechanism
- Co-delivery strategy combining hydrophilic and lipophilic actives in a stable carrier
Limitations
- No human clinical data or long-term safety/toxicology assessments
- Anti-aging clinical endpoints (e.g., wrinkle depth, elasticity) were not evaluated
Future Directions: Evaluate human ex vivo skin penetration and early clinical efficacy, assess skin tolerability and photostability, and benchmark against established anti-aging actives.
3. Natural pigments from the endophyte Aspergillus westerdijkiae and evaluation of their bioactivities.
An endophytic A. westerdijkiae strain produced pigment fractions with antimicrobial, antioxidant, and enzyme-binding activities, with gamma irradiation significantly boosting pigment yields. Structural analyses identified aspergillic acid metal complexes and other metabolites, supporting sustainable, multifunctional pigment development for cosmetic applications.
Impact: Provides a versatile microbial platform for natural pigments with multiple bioactivities, aligning with demand for safer, eco-friendly cosmetic colorants and demonstrating process intensification via irradiation.
Clinical Implications: While not clinical, the findings support development of safer, bioactive colorants and antioxidants for cosmetics, potentially reducing reliance on synthetic dyes and enabling added functional benefits.
Key Findings
- A. westerdijkiae 17P produced pigment fractions (17P1–17P4) with antimicrobial and antioxidant activities; 17P2 achieved 83% DPPH scavenging at 1000 mg/mL and cytotoxicity against MCF-7/HepG2 (IC50 250 mg/mL).
- ITC showed strong binding of 17P2 to acetylcholinesterase (Kd 1.63 µM) and butyrylcholinesterase (Kd 0.03 µM), with interactions also observed for MAO-A and PPAR-γ.
- UHPLC-MS/NMR identified metabolites including aluminium/iron aspergillic acid complexes, penicillic acid, and preussin.
- Gamma irradiation at 2000 Gy significantly increased yields of red, yellow, and orange pigments.
Methodological Strengths
- Comprehensive bioactivity profiling coupled with structural elucidation (UHPLC-MS/NMR)
- Process intensification demonstrated via gamma irradiation to boost pigment yields
Limitations
- Potency for some activities is modest (e.g., high IC50 values), and safety of metal-complex pigments requires evaluation
- No data on dermal compatibility, stability in formulations, or human exposure
Future Directions: Optimize yields and remove undesirable metabolites, assess dermal safety and stability in cosmetic formulations, and evaluate color performance and bioactivity in skin-relevant models.
