Abstract:
Here we report supramolecular hydrogelators made of nonsteroidal anti-inflammatory drugs (NSAID) and small peptides. The covalent linkage of Phe–Phe and NSAIDs results in conjugates that self-assemble in water to form molecular nanofibers as the matrices of hydrogels. When the NSAID is naproxen (1), the resultant hydrogelator 1a forms a hydrogel at a critical concentration (cgc) of 0.2 wt % at pH 7.0. Hydrogelator 1a, also acting as a general motif, enables enzymatic hydrogelation in which the precursor turns into a hydrogelator upon hydrolysis catalyzed by a phosphatase at physiological conditions. The conjugates of Phe–Phe with other NSAIDs, such as (R)-flurbiprofen (2), racemic flurbiprofen (3), and racemic ibuprofen (4), are able to form molecular hydrogels, except in the case of aspirin (5). After the conjugation with the small peptides, NSAIDs exhibit improved selectivity to their targets. In addition, the peptides made of D-amino acids help preserve the activities of NSAIDs. Besides demonstrating that common NSAIDs are excellent candidates to promote aromatic–aromatic interaction in water to form hydrogels, this work contributes to the development of functional molecules that have dual or multiple roles and ultimately may lead to new molecular hydrogels of therapeutic agents for topical use.

Abstract:
We report herein the use of an aromatic–aromatic interaction to produce small molecule hydrogelators that self-assemble in water and form molecular nanofibers in the resulting hydrogels. Among these hydrogelators, a hydrogelator (6) made from a phenylalanine and a cinnamoyl group represents the lowest molecular weight (MW = 295.33 g/mol) peptide-based hydrogelator prepared to date. The supramolecular hydrogels were characterized by transmission electron micrograph (TEM) and fluorescence spectroscopy, and the results obtained by both techniques correlate well with their rheological properties. Notably, compound 6 can undergo cis/trans-isomerization upon UV irradiation.

Abstract:
Systems formed by the supramolecular assemblages of organic molecules known as organogelators and hydrogelators are currently, and only recently, a subject of great attention and promise. In this context, low molecular weight gelators (LMWGs) are of particular interest because they provide a bottom-up approach to the formation of supramolecular architectures through self-assembly. Gelator molecules do so via the initial formation of a one-dimensional array of individual molecules bound non-covalently through forces such as: hydrogen bonds, electrostatic forces, Van der Waals interactions, and other weak forces such as π-π interactions. These interactions then lead to secondary structure formation through a similar assembly mechanism. Understanding the gelation process through characterization techniques is critical to the development of a design rationale for gelator molecules. Past and current research performed by the Wang group indicates that analogues of various 4,6-benzylidene acetals form stable gels in organic, aqueous, and organic/aqueous solvents at varying concentrations. The basis of varying the 4,6-protecting groups on glucose and glucosamine derivatives is to discern the relative structure activity relationships of these systems, and as well to fabricate functional systems which respond to external stimulus. Stimuli responsive or trigger release gel systems formed by sugar based low molecular weight gelators (LMWGs) have applications as smart biocompatible materials, and such responsiveness in various media was explored and developed to determine the feasibility of such applications using monosaccharide derivatives.

Awhida, Salmah. "Functionalised dipeptides as hydrogelators for energy transfer and as drug delivery vehicles." Thesis, University of Liverpool, 2015. http://livrepository.liverpool.ac.uk/2014048/.

Full text
Abstract:
This thesis will cover aspects of functionalised dipeptide hydrogels and their application in energy transfer and as vehicles for drug delivery. In the first section, a large number of dipeptides conjugated to different aromatic groups were synthesised. We synthesised 35 dipeptides conjugated to different aromatic groups (naphthalene, anthracene, phenanthrol, anthraquinone, carbazole and pyrene). We synthesised a large number of dipeptides with different hydrophobicity and different aromatic groups in order to study their ability to form gels and study the mechanical properties of the gels. The second part of this thesis will investigate the formation of hydrogels based on dipeptides with different aromatic groups. The focus in this section was on the gelation as well as the effect of changing the solvent and changing the amino acids used. This section then explores the properties of the resulting hydrogels. A number of different dipeptides containing different amino acids were tested, some of which formed gels and others. The dipeptides also had different pKa values. This factor was shown to be important in driving the preferential selection of a certain amino acids. The thesis then describes energy transfer which can occur between two dipeptides (pyrene and anthracene dipeptides), or between a dipeptide and a dansyl derivative (phenanthrol and dansyl, or carbazole and dansyl). These results showed that energy transfers can occur in these specific hydrogels. In all other cases, no evidence for energy transfer was found. This may imply that the packing of the fibres is important for energy transfer and this should be the focus of future work. The final section of this thesis describes the controlled release of model dyes from these gels. We studied controlled release from FmocFF hydrogels and from one other functionalised dipeptide hydrogel at different gelator concentrations and at different pH. The release of the dye from the hydrogel can be controlled by different factors, including the pH, peptide concentration, the microstructure and the mesh size. Furthermore, choosing the right method to prepare hydrogel allows us to control the microstructure for hydrogel to be injectable. Therefore, by controlling these entire factors we can use these kinds of hydrogels for drug delivery applications.

Full text
Abstract:
The overall objective of this thesis was to elucidate molecular design rules for the preparation of self-assembled aromatic peptide amphiphile based hydrogels. Aromatic peptide amphiphiles can be considered as having three distinct parts: the N-terminal aromatic group, peptide sequence, and the linker between the two. A systematic variation of these three molecular components has in the first instance revealed that contrary to popular belief, the antiparallel or parallel H-bonding supramolecular conformations associated with aromatic peptide amphiphiles cannot be distinguished by FTIR experiments alone. Instead, the 1685 cm-1 peak commonly assigned to an antiparallel arrangement, relates to the methoxycarbonyl linker if present in these systems. The choice of linker is also seen to have implications for assembly in both the aromatic and peptidic domains - as seen by fluorescence emission and FTIR respectively. In addition, the linker influences the supramolecular chirality of the f ibrous nanostructures by CD. The optimal linker for effective self-assembly and gelation is observed to depend primarily on the corresponding aromatic moiety, with fluorenyl and pyrenyl systems exhibiting differential preferences for relatively rigid and relatively flexible linkers, respectively. Besides covalent alterations, aromatic peptide amphiphile materials can also be modified through co-assembly. Here, the co-assembly structure is found to vary depending upon the aromatic and peptide segments associated with co-assembly constituents. Orthogonal co-assembly is observed in systems with different aromatic and peptide parts, as inferred by a preservation of characteristic spectroscopy and material properties associated with the assembly of individual constituents. In contrast, nanoscale phase separation is found to be disfavoured in systems that share either a common aromatic or peptide segment between co-assembly constituents. Consequently, for cooperative and disruptive systems, spectroscopy reveals substantial interactions between constituents, whilst material properties are also found to be affected through co-assembly. Finally, preliminary work demonstrates the functionalisation of bulk electrodes and MEA devices with electrochemically deposited hydrogel coatings possessing an electronic core furnished with a biocompatible coating as derived from the aforementioned co-assembly design rules. Coated electrodes are found to exhibit similar impedances to those of uncoated nodes, but prove inferior to platinised equivalents. Future work will focus on optimising said electrode impedances for potential neuron-device interface applications.

Abstract:
This thesis reports a number of studies that examines low molecular weight hydrogelators forming through in situ chemical reactions and gel the water in which this reaction occurs. This in situ gelation process has allowed a number of chemical and physical reactions and assembly processes to be investigated. Pathway complexity, an exciting concept within chemical systems has been explored with a multi-reactive hydrazone based gelation system that allows different gels to be formed from a single starting point through navigation of the systems' energy landscape. This work inspired the development of a large family of imine based gelators that would undergo an effectively irreversible tautomerisation. This allowed exploration and characterisation of the systems' ability to self-sort and co-assemble, at both the molecular and macroscopic level. One particular imine inspired gelator featured a much slower in situ reaction. This allowed characterisation of its reaction kinetics and demonstrated its autocatalytic behaviour. This thesis highlights the link between the chemical reactions that form the individual gelator molecules and the supramolecular assembly process. By using one to control the other, an in-depth understanding of the presented systems has been developed, allowing for the accurate targeting of desired physical properties.

Abstract:
La bioimpression 3D est une branche de l’ingénierie tissulaire actuellement en plein essor, cherchant à reproduire avec fidélité la microarchitecture complexe de tissus et organes. Malgré un large éventail de biomatériaux utilisés dans la formulation de bioencres, il s’avère essentiel de trouver une alternative aux biomatériaux naturels et synthétiques classiquement utilisés, permettant de mimer la matrice extracellulaire et de présenter des capacités d’impression de façon conjointe.Le présent travail met en avant, pour la première fois, les capacités de la molécule bioinspirée de type nucléolipide diC16dT à permettre la formulation d’une encre de bioimpression par extrusion. L’encre, formulée dans du milieu de culture cellulaire présentait des propriétés rhéologiques lui permettant d’être imprimée de façon continue. Il a également été possible d’y incorporer des fibroblastes gingivaux tout en maintenant leur viabilité cellulaire au sein des bioconstructions. Cette encre offre également plusieurs possibilités d’adaptation, notamment en terme de concentration en diC16dT et de milieux de culture en vue de répondre aux exigences d’autres types cellulaires. Enfin, des travaux préliminaires ont permis l’incorporation de liposomes dans la formulation de l’encre sans affecter ses capacités d’impression. Ceci permettra d’envisager la délivrance de substances actives ou d’éléments nutritifs au sein des bioimpressions, fonctionnalité des liposomes qui, à notre connaissance n’avait jamais été mise en valeur auparavant
3D bioprinting is an emerging field of tissue engineering, that aims at faithfully reproducing the complex microarchitecture of tissues and organs. Despite a wide range of biomaterials used in bioink formulation, it is essential to find an alternative to the natural and synthetic biomaterials conventionally used, mimicking extracellular matrix and presenting printing capabilities jointly.The present work demonstrated for the first time, the ability of the bioinspired nucleolipid molecule diC16dT to formulate an extrusion bioprinting ink. The ink formulated in cell culture medium showed rheological properties allowing its continuous printability. It was also possible to incorporate gingival fibroblasts while maintaining the cell viability within bioconstructions. This ink also offered several adaptation possibilities, especially in terms of diC16dT concentration and cell culture medium to meet other cellular types requirements. Finally, the preliminary work showed the feasibility of the incorporation of liposomes into the ink formulation without affecting its printing capabilities. Thus, it would possible to further consider the delivery of active substances or nutrients within the bioconstructions. This application has to the best of our knowledge not been developed yet for liposomes

Two low molecular weight hydrogelators have been developed by us. These two hydrogelators are the glycolipids that consist of glucosamine, tethering the (2S,3S)-2,3-dihydroxydecanoyl acid and (2R,3R)-2,3- dihydroxy tetradecanoyl acid, respectively.(S10 and R14). Among these two compounds, S10 a reversible gelator exhibits the stimulus-responsive ability at pH 3.0-5.0. The asymmetric synthese of these two dihydroxyalkanoyl acids have been accomplished by using chiral-pool method strategy. Herein, D-ribose is used as the starting material to synthesize these two optically active dihydroxyalkanoyl acids that configurations are mirro image each other at the same time.

The wide number of microrheology methods and techniques serve as new tools for measuring the rheology of soft materials. Several emerging applications of microrheology are presented, including the rheology of hydrogelators, gelation kinetics, and degradation (gel breaking). Viscosity measurements, in particular of protein solutions, is also discussed. These problems generally take advantage of the small volume requirements of microrheology as well as its sensitivity. The chapter begins with a discussion of mechanical and microrheology operating regimes to aid the reader in planning experiments. It concludes with a discussion of emerging trends and future areas of microrheology, including interfacial rheology.

Full text
Abstract:
A new issue for the scientific community is to find efficient replacements for unhealthy fat without damaging the organoleptic qualities of the food product in light of growing concerns about the consumption of harmful trans fats in the diet. Bigel is supposedly a novel structured fat system utilised for industrial purposes due to their nutritional advantages, one of numerous solutions intended to replace trans fats in food. These have a lot of potential in the food industry, and are composed of an aqueous phase known as a hydrogel and an organic phase known as an organogel or oleogel. A gel known as an oleogel has oil as its liquid component. Oleogelators, which aid in the development of gels, frequently have low molecular weight, whereas typical hydrogelators have large molecular weight since they are polymeric. A hydrogel is a gel in which water serves as the immobilised phase. Therefore, a bigel is a biphasic system made up of an oleogel and a hydrogel. This chapter will concentrate on the various bigel formulation techniques and chemistry, as well as their latest food uses, and other industries that fit their requirements.

Abstract:
Sucralose differs from sucrose only by virtue of having three Cl groups instead of OH groups. Its intriguing features include being noncaloric, noncariogenic, 600 times sweeter than sucrose, stable at high temperatures/acidic pH's, and void of disagreeable aftertastes. These properties are attractive as food additive, one of which is as hydrogel obtainable via the technique of molecular gelation using a sucralose-derived low-molecular weight gelator (LMWG). The process of molecular gelation entails using specially designed lipid-like amphiphilic molecules capable of self-assembling in a liquid solvent to form a 3D-network. A rational molecular design would involve appending lipophilic alkyl chain to sucralose to afford sucralose-based amphiphiles. Our preliminary study has shown that sucralose, unlike sucrose, is unreactive under biocatalytic conditions using lipase enzyme, which is consistent with its reported lack of reactivity by hydrolytic enzymes in the body. Hence, the aim of this work was (i) to use computation and simulations to further understand sucralose's lack of enzymatic reactivity and (ii) to synthesize the sucralose-based amphiphiles using conventional chemical synthesis and systematically study their tendency towards hydrogelation. Three of the sucralose-based amphiphiles (SL-5, SL-6 and SL-7) proved to be successful hydrogelators. The gelators also showed the ability to gel selected beverages. The LMWGs gelled quantities of water and beverage up to 71 and 55 times their weight, respectively, and remain thermally stable up to 144 °C.

Full text
Abstract:
Functional foods are gaining traction as a source of peptides possessing hydrogelation properties. Analysis of peptides (n=429) in egg white protein hydrolysates resulted in the identification of six peptides: IFYCPIAIM, NIFYCPIAIM, VLVNAIVFKGL, YCPIAIMSA, MMYQIGLF, and VYSFSLASRL as prominent self-assembly candidates based on prediction of their aggregation-prone segments. The objective of this study was to characterize the hydrogel formed via self-assembly of the peptides. Of the six peptides studied, NIFYCPIAIM and MMYQIGLF showed promising self-assembly and hydrogelation properties. Thioflavin T kinetics indicated that NIFYCPIAIM possesses the strongest self-assembly property, confirmed by dynamic light scattering which indicated the largest average particle diameter was achieved after 24 hours. Rheological characterization indicated that all six peptides possessed viscoelastic pseudoplastic properties and some were able to regain some level of viscosity following the exertion of shear stress. Finally, transmission electron microscopy of the six peptides showed the development of fibrillar structures of varying morphologies after 24 hours. The remarkable difference in self-assembly and hydrogelation properties of NIFYCPIAIM, IFYCPIAIMSA and YCPIAIMSA, which share a common sequence YCPIAIM, indicate the importance of amino acid sequence in the formation and property of peptide hydrogels. Identification of the egg white-derived peptides with hydrogelation properties shows a promising future for the use of functional foods in applications of drug delivery systems and tissue engineering, in the food, pharmaceutical, cosmetics, and biomedical sectors.
