    Jan 07, 2017 · Multistage drug delivery systems (Ms-DDS), also referred to as stimuli-responsive or activatable systems, show different behaviors during systemic circulation and in the tumor microenvironment. Ms-DDS have been developed in the 1970s when the first thermo-sensitive liposome for accelerated and quick release of drugs in the tumor was designed 8 .Author: Binlong Chen, Wenbing Dai, Bing He, Hua Zhang, Xueqing Wang, Yiguang Wang, Qiang Zhang

    Jan 07, 2017 · The development of traditional tumor-targeted drug delivery systems based on EPR effect and receptor-mediated endocytosis is very challenging probably because of the biological complexity of tumors as well as the limitations in the design of the functional nano-sized delivery systems. Recently, multistage drug delivery systems (Ms-DDS) triggered by various specific tumor microenvironment …Author: Binlong Chen, Wenbing Dai, Bing He, Hua Zhang, Xueqing Wang, Yiguang Wang, Qiang Zhang

    Abstract. Efficient delivery of DNA‐toxin anticancer drugs into nucleus of targeted tumor cells while simultaneously minimizing the side effects to normal tissue is a major challenge for cancer therapy. Herein, a multistage continuous targeting strategy based on magnetic mesoporous silica nanoparticles to overcome the challenge is demonstrated.Author: Zhenhua Li, Kai Dong, Sa Huang, Enguo Ju, Zhen Liu, Meili Yin, Jinsong Ren, Xiaogang Qu

Enzyme-responsive multistage vector for drug delivery to ...

    https://www.sciencedirect.com/science/article/pii/S1043661816308143
    The major difference between the enzyme-stimulated multistage vector (ESMSV) and the majority of previously reported enzyme-responsive drug delivery platforms is the location of drug release. While the ESMSV increases tumor-specific exposure to drugs, the drug release process does not take place in the extracellular environment, as MMPs target the bond between nanoparticles and microparticles.Author: Yu Mi, Joy Wolfram, Joy Wolfram, Chaofeng Mu, Xuewu Liu, Elvin Blanco, Haifa Shen, Haifa Shen, Mauro...

MULTI-STAGE DRUG DELIVERY SYSTEM - Patent - Europe PMC

    http://europepmc.org/patents/PAT/WO9423705
    A drug delivery system (10) includes a first capsule half (12) having an inner chamber (16) for containing a drug (18) therein. A plug (28) is disposed in a passageway (26) of the capsule half (12) for plugging the opening (24) thereof. The plug (28) is releasable from the passageway opening (24) upon the application of pressure from within the inner chamber (16).

    https://www.pnas.org/content/108/6/2426
    Feb 08, 2011 · Multistage nanoparticle systems provide additional tunability in the spatial control of delivery to solid tumors. Because of the multiple physiological barriers that a therapeutic agent must encounter, a multistage nanoparticle system can enhance penetration by changing its size, charge, shape, flexibility, and/or surface coating to suit the transport across each barrier.Author: Cliff Wong, Triantafyllos Stylianopoulos, Jian Cui, John Daniel Martin, Vikash P.
