Small mols. play remarkable roles in promoting tissue regeneration, but are limited by their burst release. Various bioactive mols. are required to create a suitable niche for better skin regeneration by controlling their release behaviors. Herein, a small mol. SB216763, a GSK-3 inhibitor, was loaded on silk fibroin nanofibers (SNF), and then mixed with chitosan (CS) to prepare the small mol.-loaded composite bionic scaffolds (CSNF-SB). Given the interaction of SNF and SB216763, the sustained release of SB216763 for more than 21 days was achieved for SNF and CSNF-SB composite scaffolds. Compared to drug-free CSNF scaffolds, CSNF-SB showed better cell adhesion and proliferation capacity, suggesting bioactivity. The upregulated expression of β-catenin in fibroblasts in vitro revealed that the released small mols. maintained their function in composite scaffolds. Quicker and better wound healing was realized with the drug-loaded scaffolds, which was significantly superior to that treated with drug-free scaffolds. Unlike the DFO-loaded silk hydrogel system, hair follicle neogenesis was also found in the drug-loaded-scaffold treatment wounds, demonstrating functional recovery. Therefore, silk nanofibers as versatile carriers for different small bioactive mols. could be used to fabricate scaffolds with optimized niches and then achieve functional recovery of tissues. The small mol.-loaded bionic scaffolds have a promising future in skin tissue regeneration. In the experiment, the researchers used many compounds, for example, 3-(2,4-Dichlorophenyl)-4-(1-methyl-1H-indol-3-yl)-1H-pyrrole-2,5-dione (cas: 280744-09-4HPLC of Formula: 280744-09-4).
3-(2,4-Dichlorophenyl)-4-(1-methyl-1H-indol-3-yl)-1H-pyrrole-2,5-dione (cas: 280744-09-4) belongs to indole derivatives. Indole could be stereoselectively alkylated with chiral cyclopentyl sulfone reagent. Due to this activity, the indole ring system has become an important component or intermediate in the synthesis of heterocycles.HPLC of Formula: 280744-09-4
