Amphiphilic diblock copolymers bearing histone deacetylase inhibitors (HDACis) (4-phenyl butyric acid and valproic acid) were synthesized by ring-opening polymerization of γ-4-phenylbutyrate-ε-caprolactone (PBACL), γ-valproate-ε-caprolactone (VPACL), and ε-caprolactone (CL) from a poly(ethylene glycol) (PEG) macroinitiator. These amphiphilic dibloc...

The attachment of Histone deacetylase (HDAC) inhibitors via covalent bonds to biocompatible and biodegradable block copolymers provides a new research direction for cancer treatment. Herein, we report the synthesis and characterization of valproic acid ester pro-drug micelles of amphiphilic polycaprolactone block copolymers and their potential appl...

Block copolymers synthesized by the ring-opening polymerization of γ-2-[2-(2-methoxyethoxy)ethoxy]ethoxy-ɛ-caprolactone (ME3CL), γ-2-methoxyethoxy-ɛ-caprolactone (ME1CL), and ε-caprolactone (CL) are reported. Previously, diblock copolymers of PME3CL-b-PME1CL displayed excellent thermoresponsive tunability (31 – 43 °C) and self-assembled into micell...

Due to the high cost and uncertain success of new drug development, tremendous effort is devoted to increasing the efficacy of established anti-cancer drugs. Development of polymer prodrug conjugates has evolved recently in the nano-medicine field for cancer diagnosis and treatment. The major advantage of using polymer drug conjugates is that the c...

The effect of the core substituent structure on the micellar behavior of thermoresponsive amphiphilic poly(ε-caprolactone) diblock copolymer micelles was investigated through a combination of experimental and computational methods. The polycaprolactone (PCL) amphiphilic block copolymers used in this study consisted of a hydrophilic poly{γ-2-[2-(2-m...
