Peptide Stereochemistry Effects from pK_a-Shift to Gold Nanoparticle Templating in a Supramolecular Hydrogel

ACS Nano, Год журнала: 2024, Номер 18(4), С. 3011 - 3022

The divergent supramolecular behavior of a series tripeptide stereoisomers was elucidated through spectroscopic, microscopic, crystallographic, and computational techniques. Only two epimers were able to effectively self-organize into amphipathic structures, leading hydrogels or crystals, respectively. Despite the similarity between peptides' turn conformations, stereoconfiguration led different abilities engage in intramolecular hydrogen bonding. Self-assembly further shifted pKa value C-terminal side chain. As result, across pH range 4–6, only one epimer predominated sufficiently as zwitterion reach critical molar fraction, allowing gelation. By contrast, differing values higher dipole moment other favored crystallization. four tested for gold nanoparticle (AuNP) formation, with hydrogel being key control stabilize AuNPs, yielding nanocomposite that catalyzed photodegradation dye. Importantly, AuNP formation occurred without use reductants than peptide, redox chemistry investigated by LC–MS, NMR, infrared scattering-type near field optical microscopy (IR s-SNOM). This study provides important insights rational design simple peptides minimalistic green building blocks functional nanocomposites.

Nanoparticles for efficient drug delivery and drug resistance in glioma: New perspectives

CNS Neuroscience & Therapeutics, Год журнала: 2024, Номер 30(5)

Опубликована: Май 1, 2024

Abstract Gliomas are the most common primary tumors of central nervous system, with glioblastoma multiforme (GBM) having highest incidence, and their therapeutic efficacy depends primarily on extent surgical resection postoperative chemotherapy. The role intracranial blood–brain barrier occurrence drug‐resistant gene O6‐methylguanine‐DNA methyltransferase have greatly limited chemotherapeutic agents in patients GBM made it difficult to achieve expected clinical response. In recent years, rapid development nanotechnology has brought new hope for treatment tumors. Nanoparticles (NPs) shown great potential tumor therapy due unique properties such as light, heat, electromagnetic effects, passive targeting. Furthermore, NPs can effectively load drugs, significantly reduce side effects improve efficacy, showing chemotherapy glioma. this article, we reviewed mechanisms glioma drug resistance, physicochemical NPs, advances resistance. We aimed provide perspectives
