Mechanistic insights into triclocarban-induced skin barrier disruption via integrating imaging localization, multi-omics, and network toxicology.

Environmental pollution (Barking, Essex : 1987) · 2026

Humans are constantly exposed to the antimicrobial agent triclocarban (TCC) through dermal exposure to a range of household-cleaning and personal-hygiene products, but its potential effects on skin tissue still remain elusive. Here, we employed an integrated multi-omics and network toxicology strategy to explore the cutaneous toxicity of TCC and its underlying mechanisms. Atmospheric pressure… Read on PubMed →

Nonapeptide AOP-P1 ameliorates UVB-induced hyperpigmentation by suppressing melanogenesis via targeting natriuretic peptide receptor 2.

Bioorganic chemistry · 2026

Hyperpigmentation disorders remain challenging to treat because most available agents mainly act on downstream melanogenic enzymes rather than upstream regulatory mechanisms. In this study, we identified AOP-P1, an amphibian skin-derived nonapeptide, as a potent anti-melanogenic peptide with nanomolar activity and no detectable cytotoxicity. By integrating in vitro and in vivo functional assays… Read on PubMed →
