    Polymers with pH-sensitive chemical linkages, such as hydrazone, acetal, ortho ester and vinyl ester, pH-sensitive cell-penetrating peptides and cationic polymers undergoing pH-dependent protonation have been studied to utilize the pH gradient along the endocytic pathway for intracellular drug delivery.Author: Takayuki Yoshida, Tsz Chung Lai, Glen S Kwon, Kazuhiro Sako

Acetal-Functionalized Pillar[5]arene: A pH-Responsive and ...

    https://pubs.acs.org/doi/10.1021/acsabm.0c00086
    Acetal-functionalized pillar[5]arene (Ac-PA[5]) was prepared as a pH-responsive biomaterial. This biomaterial could be fabricated into nanoparticles with a narrow size distribution by an emulsion protocol. PA[5]-based nanoparticles were used to deliver anti-tumor drugs (paclitaxel and doxorubicin) in vitro. PA[5]-based nanoparticles were discovered to be a versatile drug delivery system (DDS ...Author: Shang Lan, Yamin Liu, Kejia Shi, Da Ma

Polyorthoester - Wikipedia

    https://en.wikipedia.org/wiki/Polyorthoester
    Applications. Polyorthoesters are used as hydrophobic implant materials for drug depots for continuous drug delivery by surface erosion. The active ingredient (which is homogeneously dispersed in a matrix of polyorthoester) should be released as evenly as possible into the human or animal organism over an extended period of time in a zero-order release kinetics.
