    Biofilm microenvironment activated supramolecular nanoparticles for enhanced photodynamic therapy of bacterial keratitis
    摘要:
    Infectious keratitis caused by bacterial biofilms is one of the main causes of corneal blindness, presenting a serious threat to public health. In this study, matrix metalloproteinase (MMP)-sensitive supramolecular nanoparticles (denoted as MMP-S NPs) were constructed for enhancing photodynamic antibacterial effect against biofilm-associated bacterial keratitis. MMP-S NPs were prepared by host-guest self-assembly of chlorin e6 (Ce6) conjugated beta-cyclodextrin (beta-CD) prodrug (beta-CD-Ce6) and MMP-9-sensitive peptides (YGRKKKRRQ-RRR-GPLGVRG-EEEEEE) terminated with adamantane (Ad) (Ad-MMP-S PEPs). MMP-S NPs with EEEEEE peptide shell had a negatively charged surface, preventing adhesion to the normal ocular surface or healthy corneal cells, thus enhancing tear retention time. After arriving at the infected lesions, the protective EEEEEE peptide shell of MMP-S NPs was removed, triggered by overexpressed MMP-9 in the keratitis microenvironment. The subsequently exposed cationic peptides helped the nanoparticles penetrate and accumulate in biofilms as well as bind to Gram-negative bacteria Pseudomonas aeruginosa (P. aeruginosa), which eventually improved the photodynamic antibacterial effect. Furthermore, the P. aeruginosa keratitis model verified the high effectiveness of a topical eye drop formulation of MMP-S NPs in killing bacteria by destroying the bacterial membrane as a result of in situ photodynamic activation of reactive oxygen species (ROS) formation under light irradiation. Moreover, the inflammatory response in the cornea was inhibited to a great extent. As a result, further damage to the corneal tissue was completely suppressed. This research provides a viable antibacterial alternative to fight against bacterial keratitis through effective elimination of infectious bacteria and eradication of bacterial biofilms in the cornea.

The calculated IC 50 values indicated that the antitumor activities of inclusion complexes were better than that of GTA.

    日期:——
    General syntheses for eleven β-cyclodextrins (cyclomaltoheptaoses) mono-substituted at the C6 position by a polyamine are described. The basis of the synthesis is the reaction of 6A-O-(4-methylphenylsulfonyl)-β-cyclodextrin in the presence of KI in 1-methylpyrrolidin-2-one solution. This produces a clean product and obviates the substantial purification procedures which other preparative methods often entail. Systematic studies of the variations of the pKas of the protonated amine groups and the 13C NMR spectra of the modified β-cyclodextrins with pH are reported.

    The inclusioncomplexation behavior of coenzyme Q10 (CoQ10) with the three polyamine‐modified β‐cyclodextrins (CDs) 1–3 was investigated in both solution and the solid state by means of NMR, XRD, and FT‐IR spectroscopy. The results showed that the apparent solubility of CoQ10 increased linearly upon addition of hosts 1–3, giving AL‐type phase‐solubility curves. These hosts 1–3 were able to solubilize
