Molecular hydrogels have big potential for local delivery and sustained release of therapeutic agents. In this paper, we reported on a molecular hydrogel mainly formed by the widely used anti-cancer drug of taxol. The hydrogel was formed by an ester bond hydrolysis process from a taxol derivative (Taxol-SA-GSSG, 1) and could be administrated into solid(More)
Molecular hydrogels of therapeutic agents are a novel kind of self-delivery system that can sustain release of drugs or pro-drugs. We have previously developed a molecular hydrogelator of folic acid (FA)-Taxol conjugate triggered by phosphatase. In this paper, we report a novel molecular hydrogelator system of FA-Taxol conjugates with improved synthetic(More)
Mimicking nature: The reversible formation of self-assembled nanostructures of selenium-containing peptides can be controlled by redox triggers (see scheme, VC = vitamin C). As a consequence, the catalytic activity of these peptides is switchable. These results should lead to the development of nature-mimicking smart materials with promising properties.
Supramolecular nanofibers of prodrugs hold advantages for drug release due to their high drug payload, sustained and constant drug release behavior, and stimuli responsiveness. In this study, we report on a supramolecular hydrogel mainly formed by a clinically used drug triamcinolone acetonide (TA). Such a hydrogel could only be prepared via an ester bond(More)
A novel vaccine adjuvant based on a supramolecular hydrogel of a D-tetra-peptide is reported. Antigens can be easily incorporated into the hydrogel by a vortex or by gently shaking before injection. The vaccines can stimulate strong CD8+ T-cell responses, which significantly inhibits tumor growth. This novel adjuvant is expected to enable a wide range of(More)
We showed in this study that enzymatic triggering is a totally different pathway for the preparation of self-assembling nanomaterials to the heating-cooling process. Because the molecules were under lower energy levels and the molecular conformation was more ordered during the enzymatic triggeration under mild conditions, nanomaterials with higher(More)
