Nanoparticle technologies are significantly impacting the development of both therapeutic and diagnostic agents. At the intersection between treatment and diagnosis, interest has grown for combining both paradigms into clinically effective formulations. In this study we describe a highly efficient drug vector for photodynamic therapy (PDT) and cell imaging developed by designing multifunctional and biodegradable block copolymer-gold nanoparticle (AuNP) conjugates. These conjugates act as water-soluble and biocompatible carriers that allow the delivery of a hydrophobic photosensitizer to a tumor site for PDT action. The 17.6 nm citrate-stabilized AuNPs used herein were modified with folic acid (FA)-conjugated biocompatible block copolymers through a bidentate dihydrolipoic acid (DHLA) linker. The FA-PEG-P(Asp-Hyd)-DHLA-modified AuNPs (FA-PEG-P(Asp-Hyd)-DHLA-AuNPs) were sufficiently stable that their optical properties were not changed under very harsh conditions. Then, the hydrophobic photosensitizer, pheophorbide a (Pheo), was conjugated to the stable vectors through a pH-sensitive linkage. The synthesis and composition of all copolymers were confirmed by 1H NMR measurement. The size of Pheo-conjugated FA-PEG-P(Asp-Hyd)-DHLA-AuNPs-Pheo determined by light-scattering measurements was about 54.7 nm. FE-SEM and FE-TEM images showed that these nanoparticles have a spherical shape and adequate dispersivity after modification. Confocal microscopy, flow cytometry assay, and bio-TEM measurements were used for determining the cellular uptake of Pheo and AuNPs in HeLa cells. The FA-PEG-P(Asp-Hyd)-DHLA-AuNPs-Pheo showed 99.16% cellular uptake and exhibited an excellent phototoxicity compared to free Pheo and FA-unconjugated nanoparticles at pH 6.4.

The invention particularly discloses an intelligent targeting and environmental dual-responsibility siRNA [short interfering RNA (ribonucleic acid)] delivery system for tumor, a preparation method and application. The siRNA delivery system is characterized in that siRNA is concentrated and compounded in nanometer particle nucleuses by the aid of acid-sensitive amphiphilic three-block polymers, and intermolecular disulfide bonds are formed by PAsp(MEA) on sub-surfaces, so that the siRNA can be protected, and the intelligent targeting and environmental dual-responsibility siRNA delivery system can respond to release of the siRNA in reductive cytoplasm. The acid-sensitive amphiphilic three-block polymers comprise polyethylene glycol block-intermediate block-acid-sensitive block three-block copolymers, intermediate blocks comprise polyaspartate acyl mercaptoethylamine, and acid-sensitive blocks comprise poly (diisopropyl amine) ethyl methacrylate. The intelligent targeting and environmental dual-responsibility siRNA delivery system, the preparation method and the application have the advantages that the siRNA delivery system can be applied to preparing intelligent targeting siRNA nanometer medicines for the tumor and is low in N/P ratio dependence degree, and the siRNA can be quickly and completely released at targets; a novel idea can be provided for gene delivery systems, and the intelligent targeting and environmental dual-responsibility siRNA delivery system, the preparation method and the application have important significance on preparing clinical diagnosis and treatment medicines for the tumor.

13590-42-6, Name is (S)-Benzyl 2-(2,5-dioxooxazolidin-4-yl)acetate, belongs to oxazolidine compound, is a common compound. SDS of cas: 13590-42-6In an article, once mentioned the new application about 13590-42-6.

A novel type of cellular-uptake-shielding multifunctional envelope-type mesoporous silica nanoparticle (MEMSN) was designed for tumor-triggered targeting drug delivery to cancerous cells. beta-Cyclodextrin (beta-CD) was anchored on the surface of mesoporous silica nanoparticles via disulfide linking for glutathione-induced intracellular drug release. Then a peptide sequence containing Arg-Gly-Asp (RGD) motif and matrix metalloproteinase (MMP) substrate peptide Pro-Leu-Gly-Val-Arg (PLGVR) was introduced onto the surface of the nanoparticles via host-guest interaction. To protect the targeting ligand and prevent the nanoparticles from being uptaken by normal cells, the nanoparticles were further decorated with poly(aspartic acid) (PASP) to obtain MEMSN. In vitro study demonstrated that MEMSN was shielded against normal cells. After reaching the tumor cells, the targeting property could be switched on by removing the PASP protection layer via hydrolyzation of PLGVR at the MMP-rich tumor cells, which enabled the easy uptake of drug-loaded nanoparticles by tumor cells and subsequent glutathione-induced drug release intracellularly.

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. Application In Synthesis of (S)-Benzyl 2-(2,5-dioxooxazolidin-4-yl)acetate. Introducing a new discovery about 13590-42-6, Name is (S)-Benzyl 2-(2,5-dioxooxazolidin-4-yl)acetate

PEG-based polyplex micelles, which can detach the surrounding PEG chains responsive to the intracellular reducing environment, were developed as nonviral gene vectors. A novel block catiomer, PEG-SS-P[Asp(DET)], was designed as follows: (i) insertion of biocleavable disulfide linkage between PEG and polycation segment to trigger PEG detachment and (ii) a cationic segment based on poly(aspartamide) with a flanking N-(2-aminoethyl)-2-aminoethyl group, P[Asp(DET)], in which the Asp(DET) unit acts as a buffering moiety inducing endosomal escape with minimal cytotoxicity. The polyplex micelles from PEG-SS-P[Asp(DET)] and plasmid DNA (pDNA) stably dispersed in an aqueous medium with a narrowly distributed size range of ?80 nm due to the formation of hydrophilic PEG palisades while undergoing aggregation by the addition of 10 mM dithiothreitol (DTT) at the stoichiometric charge ratio, indicating the PEG detachment from the micelles through the disulfide cleavage. The PEG-SS-P[Asp(DET)] micelles showed both a 1-3 orders of magnitude higher gene transfection efficiency and a more rapid onset of gene expression than PEG-P[Asp(DET)] micelles without disulfide linkages, due to much more effective endosomal escape based on the PEG detachment in endosome. These findings suggest that the PEG-SS-P[Asp(DET)] micelle may have promising potential as a nonviral gene vector exerting high transfection with regulated timing and minimal cytotoxicity.

A near infrared fluorescent polymeric drug delivery system (NIRF DDS) with pH-responsive drug release properties has been designed and developed. This material was prepared by chemical conjugation of the anticancer drug doxorubicin and hydrophobic aminocyanine dye to triblock copolypeptide via hydrazone and amide bonds, respectively. Conjugation with aminocyanine shows almost no toxicity of the material, while conjugation with doxorubicin induces pronounced toxicity on the original biocompatible material. The pH sensitive drug release nature of the near infrared fluorescent polymeric drug (NIRF prodrug) was confirmed by accelerated drug release at pH of 5.0 via an in vitro drug release experiment and gradual drug cleavage from the NIRF prodrug during a confocal laser scanning microscopic (CLSM) experiment. The CLSM experiment also reveals that the released drug subsequently migrated to the nucleus, while the polymeric residue still remained in cytoplasm, indicating that the as-prepared polymer can be a promising candidate for theranosis of cancer.

ABA triblock copolymers comprised of poly(beta-benzyl-L-aspartate) (PBLA) as an A segment and poly(ethylene oxide) (PEO) as the B segment were precisely synthesized by a ring-opening polymerization of the N-carboxyanhydride of BLA initiated from amines at both terminals of the PEO chain. The copolymers have a number-average molecular weight (Mn) of 1.5 × 10 4-3.6 × 104 and a monodisperse molecular weight distribution in the range 1.04-1.07. The copolymer films casted from a dichloromethane solution were flexible and elastic despite their low M n. The film formed a hierarchical structure, i.e., the chains adopted an alpha-helix-72 helix-alpha-helix conformation and was highly crystallized, forming a long-range ordering structure which resulted in a rodlike construct arranged like ripples, as confirmed by Fourier transformed infrared spectroscopy, X-ray diffraction, and atomic force microscopy. Differential scanning calorimetry confirmed that the film showed a melting endotherm of the PEO segment at 313-326 K depending on the PBLA content. The film became very soft and behaved like rubber above the melting temperature. When the film was successively cooled, the crystalline diffraction became less intense, especially in terms of the PBLA segments whose conformation partially transformed from alpha-helices to beta-sheets, and the film showed enhanced strength and drastically increased deformation, with a strain of more than 500% accompanied by a necking phenomenon. The relationship between the mechanical properties and the structure is also discussed.
