Chen, Chao. "Amphiphilic dendrimers for siRNA delivery." Thesis, Aix-Marseille, 2015. http://www.theses.fr/2015AIXM4738.
Повний текст джерелаA key challenge in RNAi-based gene therapy is the safe and effective siRNA delivery. Recently, our group has established amphiphilic dendrimers as robust and effective nonviral delivery vectors for siRNA, which combine the beneficial delivery features of both lipid and dendritic polymer vectors while overcoming their shortcomings.With the desire to understand the underlying mechanism of amphiphilic dendrimers for efficient delivery, I performed a structure/activity relationship (SAR) analysis of a series of dendrimers featuring hydrophobic tails of different lengths during my PhD thesis. We systematically investigated these dendrimers for their self-assembling characters and their capacities for both binding and delivery of siRNA. Our results demonstrate that an optimal balance between the hydrophobic alkyl chain length and the hydrophilic dendritic portion plays a crucial role in the self-assembly and the delivery activity towards siRNA.Furthermore, we developed a novel bola-amphiphilic dendrimer by combining bola-amphiphiles and our amphiphilic dendrimers and studied their self-assembly properties and the corresponding siRNA delivery efficiency. This peculiar bola-amphiphilic vector was able to respond to reactive oxygen species for specific delivery, opening a new perspective for the design of stimuli-trigged vectors for targeted siRNA delivery.Finally, I studied the “proton sponge effect” of the amphiphilic dendrimer vectors using the Langmuir monolayer film technique. Our results gave direct evidence of swelling of the amphiphilic dendrimers upon protonation, offering unambiguous experimental data to support the “proton sponge effect”

The ability to introduce therapeutic at a specified location and time to a healing traumatic wound deep within the body by external non-invasive stimulus could provide great long-term benefit to patients. In this work, we have examined systems consisting of or including amphiphilic copolymers towards deep-tissue externally triggered localized therapeutic delivery applications. First, we probed a polyelectrolyte multilayer incorporating poly(L-glutamic acidtriethylene glycol-diclofenac) copolymer micellar aggregates for near-infrared responsive enhanced therapeutic delivery. It was discovered that the films released small-molecule non-steroidal anti-inflammatory drug diclofenac up to five-fold faster during remote irradiation with near-infrared. The near-infrared source was effective at generating more-rapid release from films with tissue mimic penetration depths of at least twelve centimeters. Irradiations in immediate succession produced diminishing rates of release. The highly near-infrared responsive behavior was attributed to a delayed-elution mechanism. In this mechanism, the diclofenac was first hydrolytically cleaved from unimers in the film and then resided within the hydrophobic cores of micellar aggregates until freed by energy imparted by the near-infrared irradiation. Gold nanorods were incorporated into the films to enhance the response of the films to near infrared above controls. Due to non-covalent suspension of the nanorods, aggregation led to a kinetically dependent enhancement of performance. Next, we improved the synthesis of a copolymer of 2-(dimethylamino)ethyl methacrylate with a spiropyran methacrylate by atom transfer radical polymerization for increased kinetic control. From there, we optimized the composition of this multiresponsive copolymer such that isomerization of the spiropyran moiety brought about a solubility transition surrounding 37°C. This property of the copolymer was designed such that the solubility shift by remote photo-trigger would bring about therapeutic release in a polymer multilayer system analogous to the diclofenac system. Overall, this work demonstrates the utility of engineering amphiphilic copolymers as a powerful approach to impart remotely triggerable therapeutic release properties for use with implants deeply located within the body.

Повний текст джерелаThis project aims to investigate the synthesis and properties of dual stimuli-responsive block copolymers able to self-assemble into supramolecular aggregates in response to two stimuli: the temperature and the presence of carbon dioxide in the aqueous solution. Therefore, a range of amphiphilic diblock copolymers composed of a hydrophilic block of polyethylene glycol methylether acrylate (PEGA) and a statistical block of PEGA, diethylene glycol ethyl ether acrylate (DEGA) and diethylaminoethyl acrylate (DEAEA) was prepared via nitroxide-mediated polymerization (NMP) and the level of control of each synthesis was studied. We evidenced that temperature and CO2 play a different role in the self-assembly of such block copolymers. Finally, the introduction of dextrane as hydrophilic block coming from renewable resources allows for the preparation of novel “smart” amphiphilic diblock copolymers. In order to synthesize these block copolymers with well-defined structure, both NMP and atom transfer radical polymerization (ATRP) were investigated in parallel

Повний текст джерелаIn this study, we developed and characterized multi-sensitive triblock copolymers composed of outer blocks with controlled length and amphiphilicity based on pullulan or poly(acrylic acid) (PAA). These copolymers are composed of a fixed middle block based on a LCST thermosensitive poly(propylene oxide) (PPO), the Jeffamine® D2000. Pullulan size was reduced by acid hydrolysis (pH 2) at 80 °C. Pullulan was then coupled to the D2000 by reductive amination to form pullulan-b-D2000-b-pullulan triblock copolymers. The low reactivity of this reaction and the loss of copolymer during purification did not allow to study its behavior in aqueous solution. PAA-terminated polymers were obtained by atom transfer radical polymerization (ATRP) of a precursor of PAA, tert-butyl acrylate (tBA), and subsequent hydrolysis. Jeffamine® was previously converted in an amide-type di-brominated macroinitiator. After proving the controlled character of the ATRP, P(tBA)-b-D2000-b-P(tBA) triblock copolymers with low dispersity (<1,3) and various size were synthesized. P(tBA) outer blocks were then completely or partially hydrolyzed in PAA or P(AAstat-tBA). P(AA)x-b-D2000-b-P(AA)x copolymers both exhibit LCST and UCST behavior, leading respectively to the formation of macroscopically visible aggregates and soluble aggregates. These UCST and LCST behavior can be controlled by the degree of ionization and the size of PAA blocks. Furthermore, the soluble aggregates are characterized by a very low aggregation number (between 1 and 3), which is mainly due to the triblock structure of the copolymer. Increasing the hydrophobicity of the P(AA-stat-tBA) blocks highlights the formation of highly aggregated soluble structures having a size which increases with higher tBA/AA ratio. However, the addition of hydrophobicity resulted in the loss of LCST behavior

Повний текст джерелаStimuli responsive gels, also known as smart materials, have emerged as powerful platforms thanks to their unique property to sense their surroundings and to change their macroscopic behavior in time and space for a wide range of applications from biomedicine to environmental chemistry. In this context, this dissertation is devoted to the design and the study of physico-chemical properties of novel responsive systems by chemical modifications of low molecular weight gelators(GlycoNucleoBolaAmphiphiles or GNBAs) sensitive to specific triggers: light, enzymes and pH. First, light sensitive GNBAs featuring a photoresponsive stilbene unit have been synthetized using a stereoselective metathesis reaction. The trans isomers exhibited strong and thixotropic gels inwater/ethanol mixtures. Photo-isomerization under UV-light led to the formation of the bended cis derivatives resulting in the 3D network destruction. The reversibility of this phenomenon was however partly limited owing to the cis isomer thermodynamic stability and the formation of by-product. Next, hydrophilic GNBAs displaying lactose moieties sensitive to ß-galactosidase have been synthetized. According to their structure, different gelation kinetics observed after cleavage highlighted that gelation ability was impacted in complex media. Similarly, ester-linked fatty acids GNBAs sensitive to esterase have been designed to expand the scope of the enzyme responsive set of gelators. Finally, pH-sensitive GNBAs containing an orthoester moiety were synthesized. Subjected to different pH values found in vivo they showed around 50 % of cleavage and the slow formation of high viscous material. Previously described ester based GNBAs have also been investigated in acidic or basic pH

Повний текст джерелаAmphiphilic copolymers have attracted a large interest as they find numerous applications in catalyst support, bio-separation devices and drug delivery systems. Their auto-association in aqueous media forming micelles are well-studied, particularly by the use of smart polymers which display a significant physicochemical change in response to modification of their environment. In this work, pH and temperature responsive polymers have been studied for the elaboration of micellar systems composed of a hydrophobic core from linseed oil and hydrophilic stimuli-sensitive coronna. However the common approach is to design one specific macromolecule for one given application, with sometimes complex composition and/or architecture. We aim to investigate a straight-forward pathway towards micellar systems with finely tuned sensitivities by the cooperative self-assembly of two different copolymers to manipulate the physico-chemical behavior of the final mixed system
