Abstract: Currently, nutraceuticals and functional food/cosmeceutical sectors are seeking natural molecules to develop various types of phytopharmaceutical products. Flavonoids have been reported in antioxidant and many medical/pharmacological activities. Monochoria angustifolia or Siam violet pearl medicinal plant is the newest species of the genus Monochoria C. Presl, which have long been consumed as food and herbal medicines. Though previous work showed that apigenin-7-O-glucoside is the most abundant antioxidant phytochemical found in this medicinal plant, the report on anti-aging activity is still lacking and needs to be filled in. The objective of this work is to explore anti-aging capacities of the most abundant antioxidant phytochemical reported in this plant using both in silico and in vitro assessments. In addition, pharmacokinetic properties were predicted. Interestingly, the results from both in silico and in vitro analysis showed a similar trend that apigenin-7- O-glucoside is a potential anti-aging agent against three enzymes. The pharmacokinetic properties, such as adsorption, distribution, metabolism, excretion and toxicity (ADMET), of this compound are also provided in this work. The current study is also the first report on anti-aging properties of this Thai medicinal plant. However, the safety and efficacy of future developed products from this compound and clinical study should be determined in the future.

Abstract

Skin aging has been associated with the onset of various skin issues, and recent studies have identified an increase in Cdc42 activity in naturally aging mice. While previous literature has suggested that CASIN, a specific inhibitor of Cdc42 activity, may possess anti-aging properties, its specific effects on the epidermis and dermis, as well as the underlying mechanisms in naturally aging mice, remain unclear. Our study revealed that CASIN demonstrated the ability to increase epidermal and dermal thickness, enhance dermal-epidermal junction, and stimulate collagen and elastic fiber synthesis in 9-, 15-, and 24-month-old C57BL/6 mice in vivo. Moreover, CASIN was found to enhance the proliferation, differentiation, and colony formation and restore the cytoskeletal morphology of primary keratinocytes in naturally aging skin in vitro. Furthermore, the anti-aging properties of CASIN on primary fibroblasts in aging mice were mediated by the ribosomal protein RPL4 using proteomic sequencing, influencing collagen synthesis and cytoskeletal morphology both in vitro and in vivo. Meanwhile, both subcutaneous injection and topical application exhibited anti-aging effects for a duration of 21 days. Additionally, CASIN exhibited anti-inflammatory properties, while reduced expression of RPL4 was associated with increased inflammation in the skin of naturally aging mice. Taken together, our results unveil a novel function of RPL4 in skin aging, providing a foundational basis for future investigations into ribosomal proteins. And CASIN shows promise as a potential anti-aging agent for naturally aging mouse skin, suggesting potential applications in the field.

Facial assessment methods for inhibiting glycation and aging effects and the correlation between glycation and aging parameters 2025-04-23 00:00

This study aimed to develop in vivo methods for assessing facial anti-glycation and anti-aging effects and to investigate the link between glycation and aging signs. We utilized an AGE reader to measure AGEs levels on the face and arms, establishing a correlation to validate the reader’s use for facial AGEs detection. Then the product’s 7-day anti-glycation effect was evaluated. And its 56-day anti-aging effects were evaluated using non-invasive probes and VISIA CR, assessing skin tone (skin brightness L* and yellowness b*, skin gloss), texture (skin elasticity R2 and firmness F4, skin pores), and hydration (skin moisture content). Correlations between facial AGEs levels and aging parameters were analyzed.

Results indicated a strong correlation between facial and arm AGEs after product application, supporting facial AGEs level as an assessment parameter. The product demonstrated substantial antiglycation and anti-aging effects, suggesting the methods’ efficacy for cosmetic evaluation. A stronger overall correlation was found between AGEs levels and skin tone than with skin texture and hydration, highlighting glycation’s impact on skin color.
