Today, drugs are an integral part of healthy human life, with new drug entities being introduced every year in clinic. The advancement of drug development brings complexity and variation, in terms of both physical and chemical properties. Some of these physicochemical characteristics are many times suboptimal, eventually requiring robust delivery systems that can precisely deliver the drugs to the desired tissues. Although many materials have been studied for the generation of drug delivery systems, there is always a need for biomaterials with better properties that can translate into superior delivery systems. In this context, new drug delivery systems that are interface-engineered at materials level for better stability and delivery efficiency in vitro and in vivo are introduced in this dissertation. In the first part of the dissertation, novel oil/water interface-engineered amphiphilic block copolymer micelles that were previously introduced by our lab were assessed for their stability in the presence of various esterase enzymes present in serum and on blood vessel walls, normally encountered by drug delivery systems on route to the targeted tissues. I also assessed the vulnerability of the polymeric micelles in presence of enzymes typically present either inside the tumor cells or secreted in the tumor microenvironment. I revealed the selective stability of empty- and docetaxel-loaded polymeric micelles to enzymatic degradation en route/in tumors and I have correlated this selective stability with polymer structure and interfacial engineering mentioned above. The unique delivery capabilities of interfacial-engineered polymeric micelles were tested in vivo using a mouse model of triple negative breast cancer. We proved that our novel engineered triblock copolymer-based drug delivery systems are superior to similar delivery systems made out of standard diblock copolymer micelles and also to the clinically used Taxotere® formulation towards cancer cell killing and tumor treatment, without displaying any significant toxicity in experimental animals. The second part of the dissertation focuses on the development and assessment of a pyridinium-based pseudo-gemini surfactant that combined the high nucleic acid packaging capacity of pyridinium lipids with the high transfection efficiency of gemini surfactants while displaying a reduced associated cytotoxic effect. I have analyzed the temperature treatment on compaction of nucleic acids into lipoplexes and I have established a high temperature annealing method for this purpose. This novel formulation technique allowed a substantial reduction of the amount of amphiphiles required to compact a specific amount of nucleic acids. This in turn also reduced the cytotoxic effect associated with the use of pyridinium amphiphiles. The effect of inclusion of colipids to lipoplex compaction, the robustness and the transfection efficiency of the lipid/nucleic acid lipoplex systems were assessed in detail, and correlations between formulation composition and biological activity were established. I was also able to show for the first time that pyridinium pseudo-gemini surfactants were able to compact different types of nucleic acids, including pDNA, mRNA and siRNA at lower charge ratios than standard, state-of-the art formulations used for this purposes. I also showed that irrespective to the nucleic acid compacted within the lipoplexes, the novel amphiphiles can efficiently deliver the cargo into the targeted cells even in the presence of very high concentration of serum, a premise for future use of these amphiphiles and formulations in vivo.

Cancer is currently the second most common cause of death in the world. Despite tremendous progress in the treatment of different forms of cancer, the five year survival rates for lung, colorectal, breast, prostate, pancreatic and ovarian cancers remain quite low. New therapies are urgently needed for the better management of these diseases. In this context, both therapeutic gene and drug delivery constitute promising approaches for cancer treatment and are addressed in this thesis. Focusing on gene delivery, we are proposing the use new pyridinium amphiphiles for obtaining gene delivery systems with improved stability and efficiency and low toxicity (Chapters 2 and 3). The main focus was on pyridinium gemini surfactants (GSs), which possess a soft charge, a high charge/mass ratio and a high molecular flexibility - all key parameters that recommend their use in synthetic gene delivery systems with in vitro and in vivo efficiency. In Chapter 2, we optimized a novel DNA delivery systems through interfacial engineering of pyridinium GS at the level of linker, hydrophobic chains and counterions. In Chapter 3, we tested the effects of blending pyridinium cationic GS into pyridinium cationic lipid bilayers and we have evaluated these blends towards plasmid DNA compaction and delivery process. We have also correlated the cationic bilayer composition with the dynamics of the DNA compaction process, and with transfection efficiency, cytotoxicity and internalization mechanism of resulted nucleic acid complexes. Toward improved drug delivery systems, we introduced new amphiphilic block copolymers synthesized from biocompatible and biodegradable segments. Although their capabilites for loading, transport and release of lipophilic substances stored in their hydrophobic cores are widely known, their stability in vivo is limited due to rapid degradation by esterases present in the body. In Chapter 4, we examined the possibility to increase the enzymatic stability of PEG-PCL macromolecular amphiphiles through interfacial engineering, in a process which separates the hydrophilic/hydrophobic interface from the degradable/non-degradable block interface. We evaluated the stability, toxicity, drug loading and release properties of these new polymers using docetaxel as a model chemotherapeutic drug. The results revealed how hydrophilic/ hydrophobic interface tuning can be used to adjust key properties of polymeric drug delivery systems of this type.

Texte intégralThis work is part of a research program on the synthesis of amphiphilic molecules havingbioactive properties, which could be used in biomedical applications or in agrochemistry.Amphiphilic molecules could be the own actor of their formulation because of the dual propertyof bioactivity and self-assembly. In this context, the first part of this work concerns the synthesisof model amphiphilic molecules derived from D-glucose and N-acetyl-D-glucosamine. The chosenway to synthesize these molecules was a regioselective reductive amination from alkylaminechains of different lengths (6, 12 and 16 carbon atoms). Compounds were characterized by NMRand Mass Spectrometry. The second part of this work was oriented towards the study of the selfassemblyproperties of molecules derived from D-glucose in an aqueous solution, alone, or mixedwith a model phospholipid. An organization with different sizes was shown with severaltechniques: light diffusion, transmission electronic microscopy, and thanks to the establishment ofa model from experimental small-angle X-ray scattering data. When the amphiphilic moleculewith 12 atoms of carbon on this hydrocarbonated chain is studied alone in a solution, ellipsoidalmicelles seem to be present, mixed with bigger aggregates (~100 nm). However, when this sameamphiphilic molecule is used in a mix with a model phospholipid, a size diminution of theassembly was observed with the increase of amphiphilic molecules in the formulations

Texte intégralThe objective of this work was to synthesize and characterize amphiphilic copolymers based on poly(ethylene glycol) (PEG) and poly(lactic acid) (PLA) intended for drug delivery applications. The polymers were chosen regarding to their biocompatibility and bioresorbability. Different architectures of amphiphilic copolymers were prepared, and their behavior in aqueous media, as well as their abilities to encapsulate drugs were studied. First, a graft copolymer was synthesized through copolymerization of a functional monomer, monopropargylated glycolide, with L-lactide to yield a functionalized polyester backbone. The latter was then grafted with different densities of hydrophilic branches of PEG. Then, a brush-like triblock copolymer was synthesized through ROP and ATRP. To this end, chain ends of a telechelic block of PLA were modified to yield a macroinitiator able to initiate oligo(ethylene glycol) methacrylate polymerization with variable substitution degrees. Self-assembly and drug loading studies revealed that architecture and hydrophobic/hydrophilic balance played a major role on the nature of the formed objects and on their encapsulation potential. Finally, to modulate and increase the efficacy of encapsulated drugs, functionalization strategies were realized. This is illustrated by the linking of a fluorescent model molecule on a triblock brush-like copolymer and, in a collaboration project, the linking of an immunostimulant peptide on an amphiphilic diblock system. Comparison with other formulations revealed that the conjugate allowed modulating and reinforcing the drug's efficacy
