Here, we report a dynamic covalent dual prodrug nanoplatform (termed SFB) that integrates the anti-inflammatory, antiapoptotic, and proautophagic effects of spermidine (SPD) and baicalein (BAI). Using phenylboronic acid-mediated linkage and reaction-induced self-assembly (RISA), SFB formed well-defined nanostructures with an exceptionally high dual-drug encapsulation (exceeding 90%). These assemblies enabled responsive and synchronized release under acidic and oxidative inflammatory microenvironments while exhibiting favorable stability and biosafety. Mechanistic studies revealed that SFB efficiently scavenged reactive oxygen species, suppressed TLR/MyD88/NF-κB-mediated inflammation, inhibited apoptosis, and restored autophagy-lysosomal homeostasis. In a mouse model of endometritis, SFB treatment markedly reduced oxidative stress, promoted tissue repair, improved endometrial receptivity, and rescued reproductive impairments associated with embryo implantation and fetal development. Collectively, SFB represents a multifunctional dynamic covalent nanoplatform that enhances therapeutic efficacy against endometrial inflammation, improves reproductive outcomes, and overcomes key limitations of conventional dual-drug delivery strategies, offering opportunities for multidrug synergistic therapy.\nCited By\nThis article has not yet been cited by other publications.\nArticle Views\nAltmetric\nCitations\nArticle Views are the COUNTER-compliant sum of full text article downloads since November 2008 (both PDF and HTML) across all institutions and individuals.
