Double hydrophilic block copolymers self-assemblies in biomedical applications. Adv Colloid Interface Sci 2020; 283:102213.

Abstract
Double-hydrophilic block copolymers (DHBCs), consisting of at least two different water-soluble blocks, are an alternative to the classical amphiphilic block copolymers and have gained increasing attention in the field of biomedical applications. Although the chemical nature of the two blocks can be diverse, most classical DHBCs consist of a bioeliminable non-ionic block to promote solubilization in water, like poly(ethylene glycol), and a second block that is more generally a pH-responsive block capable of interacting with another ionic polymer or substrate. This second block is generally non-degradable and the presence of side chain functional groups raises the question of its fate and toxicity, which is a limitation in the frame of biomedical applications. In this review, following a first part dedicated to recent examples of non-degradable DHBCs, we focus on the DHBCs that combine a biocompatible and bioeliminable non-ionic block with a degradable functional block including polysaccharides, polypeptides, polyesters and other miscellaneous polymers. Their use to design efficient drug delivery systems for various biomedical applications through stimuli-dependent self-assembly is discussed along with the current challenges and future perspectives for this class of copolymers.

Abstract
A series of amphiphilic PDMAEMA–SS–PCL chains with variable ratios of hydrophilic poly(2-(dimethylamino)ethyl methacrylate) (PDMAEMA) to hydrophobic poly(ε-caprolactone) (PCL) were prepared via ring-opening polymerization, in which the two different moieties were linked via a disulfide bond with reduction responsiveness. After cross-linking by the photodegradable o-nitrobenzyl linkage, the amphiphilic chains could self-assemble into microspheres, branched cylindrical micelles and vesicles, which were responsive to the reduction agent dl-dithiothreitol and UV light irradiation through different mechanisms. A series of cross-linked amphiphilic PDMAEMA–SS–PCL were prepared, which could self-assemble into diverse microstructures with reduction and light responsiveness.![]()

Abstract
Polymer-drug conjugates have been actively developed as potential anticancer drug delivery systems. In this study, we report the first polymer-anticancer drug conjugate with poly(glycerol adipate) (PGA) through the successful conjugation of methotrexate (MTX). MTX-PGA conjugates were controllably and simply fabricated by carbodiimide-mediated coupling reaction with various high molar ratios of MTX. The MTX-PGA conjugate self-assembled into nanoparticles with size dependent on the amount of conjugated MTX and the pH of medium. Change in particle size was attributed to steric hindrance and bulkiness inside the nanoparticle core and dissociation of free functional groups of the drug. The MTX-PGA nanoparticles were physically stable in media with pH range of 5-9 and ionic strength of up to 0.15 M NaCl and further chemically stable against hydrolysis in pH 7.4 medium over 30 days but enzymatically degradable to release unchanged free drug. Although 30%MTX-PGA nanoparticles exhibited only slightly less potency than free MTX in 791T cells in contrast to previously reported human serum albumin-MTX conjugates which had >300 times lower potency than free MTX. However, the MTX nanoparticles showed 7 times higher toxicity to Saos-2 cells than MTX. Together with the enzymic degradation experiments, these results suggest that with a suitable biodegradable polymer a linker moiety is not a necessary component. These easily synthesised PGA drug conjugates lacking a linker moiety could therefore be an effective new pathway for development of polymer drug conjugates.

Investigation of cationized triblock and diblock poly(ε-caprolactone)-co-poly(ethylene glycol) copolymers for oral delivery of enoxaparin: In vitro approach. Acta Biomater 2017; 61:180-192. [PMID: 28782723 DOI: 10.1016/j.actbio.2017.08.006] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2017] [Revised: 08/01/2017] [Accepted: 08/03/2017] [Indexed: 12/17/2022]
Abstract
In this study, poly(ε-caprolactone)-co-poly(ethylene glycol) copolymers grafted with a cationic ligand, propargyltrimethyl ammonium iodide (PTA), to fabricate the cationized triblock (P(CatCLCL)2-PEG) and diblock (P(CatCLCL)-mPEG) copolymers were investigated their potential use for oral delivery of enoxaparin (ENX). Influences of various PTA contents and different structures of the copolymers on molecular characteristics, ENX encapsulation, particle characteristics, and capability of drug transport across Caco-2 cells were elucidated. The results showed that P(CatCLCL)2-PEG and P(CatCLCL)-mPEG copolymers self-aggregated and encapsulated ENX into spherical particles of ∼200-450nm. The increasing amount of PTA on the copolymers increased encapsulation efficiency of over 90%. The ENX release from both types of the cationized copolymer particles was pH-dependent which was retarded at pH 1.2 and accelerated at pH 7.4, supporting the drug protection in the acidic environment and possible release in the blood circulation. The toxicity of ENX-loaded particles on Caco-2 cells decreased when decreasing the amount of PTA. The triblock and diblock particles dramatically enhanced ENX uptake and transport across Caco-2 cells as compared to the ENX solution. However, the different structures of the copolymers slightly affected ENX transport. These results suggested that P(CatCLCL)2-PEG and P(CatCLCL)-mPEG copolymers would be potential carriers for oral delivery of ENX. STATEMENT OF SIGNIFICANCE The anionic drugs such as proteins, peptides or polysaccharides are generally administered via invasive route causing patient incompliance and high cost of hospitalization. The development of biomaterials for non-invasive delivery of those drugs has gained much attention, especially for oral delivery. However, they have limitation due to non-biocompatibility and poor drug bioavailability. In this study, the novel poly(ε-caprolactone)-co-poly(ethylene glycol) copolymers grafted with propargyltrimethyl ammonium iodide, a small cationic ligand, were introduced to use as a carrier for oral delivery of enoxaparin, a highly negatively charged drug. The study showed that these cationized copolymers could achieve high enoxaparin entrapment efficiency, protect drug release in an acidic environment and enhance enoxaparin permeability across Caco-2 cells, the intestinal cell model. These characteristics of the cationized copolymers make them a potential candidate for oral delivery of anionic drugs for biomaterial applications.

[PMID: 28482577 DOI: 10.1016/j.msec.2017.02.163] [Citation(s) in RCA: 51] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/09/2017] [Revised: 02/13/2017] [Accepted: 02/28/2017] [Indexed: 12/11/2022]
Abstract
Deregulation of anti-apoptosis Bcl-2 protein expression was a key feature in human cancers with therapeutic resistance. Nuclear receptor Nur77 could induce the conformation change of Bcl-2 protein and converted it into an apoptosis inducer by "enemy to friend" strategy. However, the safe and effective delivery of this gene to combat therapeutic resistant cancer remained largely unexplored. In this report, we designed an amphiphilic cationic MPEG-PCL-PEI-FA copolymer, comprising biocompatible and hydrophilic methoxy-poly(ethylene glycol) (MPEG), biodegradable and hydrophobic poly(ε-caprolactone) (PCL), cationic poly(ethylene imine) (PEI) segments, and folic acid (FA) as targeting group, as a high efficient Nur77 gene carrier to folate receptor (FR) highly expressed and therapeutic resistant HeLa/Bcl-2 cancer cells. Interestingly, due to the incorporation of PCL and PEG segments, this MPEG-PCL-PEI-FA copolymer showed less toxicity but better gene transfection efficiency than non-viral gene carrier gold standard PEI (25kDa). This might be due to the formation of micelles to stabilize polyplex for enhanced gene transfection ability. More importantly, MPEG-PCL-PEI-FA copolymer exhibited excellent growth inhibition ability on therapeutic resistant HeLa/Bcl-2 cancer cells, which was FR overexpressed HeLa cervical cancer cells with high expression of Bcl-2 protein, thanks to its FA induced targeting ability, high gene transfection efficiency, and low cytotoxicity. This work signifies the first time that cationic amphiphilic MPEG-PCL-PEI-FA copolymers could be utilized for the gene delivery to therapeutic resistant cancer cells with high expression of anti-apoptosis Bcl-2 protein and the positive results are encouraging for the further design of polymeric platforms for combating drug resistant tumors.
