Polylactic acid-hydroxyacetic acid copolymer nano-drug carrier as well as preparation method and application thereof

The invention provides a PLGA (polylactic acid-hydroxyacetic acid) nano-drug carrier which is composed of PLGA nano microsphere kernel and an anillic aldehyde crosslinked chitosan housing. A preparation method of the polylactic acid-hydroxyacetic acid copolymer nano-drug carrier is as follows: dispersing a PLGA organic phase which takes dichloromethane and alcohol as a mixed solvent in a water phase to prepare PLGA microspheres by taking PVA (polyvinyl acetate) as an emulsifier by virtue of an one-off emulsion process; then, adding the PLGA microspheres into chitosan liquor, so that the chitosan is adsorbed on the surfaces of the PLGA microspheres, and then adding the chitosan on the surfaces of anillic aldehyde crosslinked PLGA microspheres. The product has a certain pH environmental responsiveness, can realize controlled release of the drug according to in-vivo pH environmental changes, is high in stability, strong in up-taking capacity for microsphere-coated medicaments by the cells, and has very good application prospect in the drug carrier for treating tumors.

Compositions and methods for recognition of RNA using triple helical peptide nucleic acids

Peptide nucleic acids containing thymidine and 2-aminopyridine (M) nucleobases formed stable and sequence selective triple helices with double stranded RNA at physiologically relevant conditions. The M-modified PNA displayed unique RNA selectivity by having two orders of magnitude higher affinity for the double stranded RNAs than for the same DNA sequences. Preliminary results suggested that nucleobase-modified PNA could bind and recognize double helical precursors of microRNAs.
