More Details: Amygdalin is widely distributed in the plant kingdom. Oral delivery of amygdalin releases hydrogen cyanide upon endogenous enzymes causing potential toxic effects to humans. Here, we fabricate Fmoc-Tyr–OH–amygdalin hydrogel (FTOA) which represents L-tyrosine derived low molecular weight hydrogelator entrapping amygdalin. Fourier Transform Infrared Spectroscopy and the Fluorescent Emission Spectrum elucidated the complexation process between the amygdalin and Fmoc-Tyr-OH (FTO). Amygdalin was sustainably released from FTOA at different pH buffer. The rheological behavior similar to the brain supported that the hydrogel tended to be a preferable neural scaffold. Moreover, animal studies showed FTOA significantly promoted neural-functional recovery. This hydrogel achieved a great decrease in damage volume according to H&E staining. Additionally, we found that FTOA enhanced tissue recovery. Simultaneously, the released amygdalin gave a markedly neural inflammatory suppression. Taken together, this study highlights that Fmoc-based gelator encapsulate amygdalin forming a stable hydrogel to perform sustained-release and improve efficacy with minimal side effects.
