Science
Mechanism of Action
This extract's anti-inflammatory properties stem from its ability to inhibit excessive nitric oxide production and downregulate key pro-inflammatory mediators such as inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-α). This action is mediated by the suppression of ERK, JNK, p38 MAPK, and NF-κB pathways. As an antioxidant, it leverages a rich profile of polyphenolic compounds, including chlorogenic acid, rutin, protocatechuic acid, and hydroxybenzoic acid. Furthermore, it displays complex melanin-modulating effects, demonstrating the capacity to increase melanin content and proliferation in melanocytes while also exhibiting anti-melanoma activity by inhibiting the MEK/ERK pathway and activating caspase-3 in cancer cells.

Key findings
- 01 In vitro studies at 25-100 μg/mL demonstrated significant inhibition of excessive nitric oxide production in lipopolysaccharide-stimulated BV-2 microglia, indicating anti-neuroinflammatory activity.
- 02 An ethanol extract at 100 μg/mL in vitro significantly inhibited the proliferation of human melanoma SK-MEL-2 cells by 28.85 ± 3.38%. A butanol fraction showed strong cytotoxic activity against SK-MEL-2 cells with low cytotoxicity against normal human dermal fibroblasts (HDFa) at up to 50 μg/mL.
- 03 An ethanol extract in vitro significantly increased the proliferation and melanin content of B16 melanocytes. It also reduced expression levels of IL-6, IL-8, and TNF-α mRNA and proteins in TNF-α-stimulated dermal fibroblasts and keratinocytes.

Verdict
Sorbus Commixta Berry Extract demonstrates promising in vitro anti-inflammatory, antioxidant, and melanin-modulating properties, but further human clinical trials and comprehensive safety assessments are required to establish its efficacy and safety for topical use.
