Usage

Uses

Used in Pharmaceutical Industry:
Tr-PEG3 is used as a solubility enhancer for increasing the water solubility of hydrophobic drugs, which can improve their bioavailability and pharmacokinetic properties. The hydrophilic PEG linker aids in the dispersion of the drug in aqueous environments, facilitating better absorption and distribution within the body.
Used in Drug Delivery Systems:
Tr-PEG3 is used as a component in the design of drug delivery systems, such as nanoparticles, liposomes, and hydrogels. The PEG chain can provide stealth properties, reducing the recognition and clearance of the delivery system by the immune system, thereby extending the circulation time and enhancing the therapeutic efficacy of the encapsulated drug.
Used in Bioconjugation and Labeling:
Tr-PEG3 is used as a spacer or linker in bioconjugation and labeling applications, such as attaching targeting ligands, fluorescent tags, or other functional groups to biomolecules like proteins, peptides, or nucleic acids. The PEG chain can improve the stability, solubility, and biocompatibility of the resulting conjugates, while the trityl ether protection group allows for selective and controlled conjugation under mild conditions.
Used in Polymer Science and Materials:
Tr-PEG3 can be utilized as a building block or additive in the synthesis of various polymers and materials, such as hydrogels, block copolymers, and surface coatings. The PEG chain can impart properties like enhanced water solubility, improved biocompatibility, and reduced protein adsorption, making these materials suitable for a range of applications, including tissue engineering, diagnostics, and sensors.

An ion conductor that recognizes osmotically-stressed phospholipid bilayers

A synthetic ion conductor (1), derived from cholic acid and spermine, has been found capable of recognizing osmotic stress in liposomes made from 1,2-dipalmitoleoyl-sn-glycero-3-phosphocholine [(C16:1)PC]. Thus, when large unilamellar vesicles of (C16:1)PC are placed under hypotonic conditions, the Na+/Li+ transport activity of 1 increases by as much as 1 order of magnitude, relative to isotonic conditions Copyright

Synthesis of a library of propargylated and PEGylated α-hydroxy acids toward "clickable" polylactides via hydrolysis of cyanohydrin derivatives

A new simple and practical protocol for scalable synthesis of a novel library of propargylated and PEGylated α-hydroxy acids toward the preparation of "clickable" polylactides was described. The overall synthesis starting from readily available propargyl alcohol, bromoacetaldehyde diethyl acetal, and OEGs or PEGs was developed as a convenient procedure with low cost and no need of column chromatographic purification. The terminal alkyne functionality survives from hydrolysis of the corresponding easily accessible cyanohydrin derivatives in methanolic sulfuric acid. Facile desymmetrization, monofunctionalization, and efficient chain-elongation coupling of OEGs further enable the incorporation of OEGs to α-hydroxy acids in a simple and efficient manner. At the end, synthesis of allyloxy lactic acid indicates that an alkene group is also compatible with the developed method. (Chemical Equation Presented).

Hydrophilic and Cell-Penetrable Pyrrolidinyl Peptide Nucleic Acid via Post-synthetic Modification with Hydrophilic Side Chains

Peptide nucleic acid (PNA) is a nucleic acid mimic in which the deoxyribose-phosphate was replaced by a peptide-like backbone. The absence of negative charge in the PNA backbone leads to several unique behaviors including a stronger binding and salt independency of the PNA-DNA duplex stability. However, PNA possesses poor aqueous solubility and cannot directly penetrate cell membranes. These are major obstacles that limit in vivo applications of PNA. In previous strategies, the PNA can be conjugated to macromolecular carriers or modified with positively charged side chains such as guanidinium groups to improve the aqueous solubility and cell permeability. In general, a preformed modified PNA monomer was required. In this study, a new approach for post-synthetic modification of PNA backbone with one or more hydrophilic groups was proposed. The PNA used in this study was the conformationally constrained pyrrolidinyl PNA with prolyl-2-aminocyclopentanecarboxylic acid dipeptide backbone (acpcPNA) that shows several advantages over the conventional PNA. The aldehyde modifiers carrying different linkers (alkylene and oligo(ethylene glycol)) and end groups (-OH, -NH2, and guanidinium) were synthesized and attached to the backbone of modified acpcPNA by reductive alkylation. The hybrids between the modified acpcPNAs and DNA exhibited comparable or superior thermal stability with base-pairing specificity similar to those of unmodified acpcPNA. Moreover, the modified apcPNAs also showed the improvement of aqueous solubility (10-20 folds compared to unmodified PNA) and readily penetrate cell membranes without requiring any special delivery agents. This study not only demonstrates the practicality of the proposed post-synthetic modification approach for PNA modification, which could be readily applied to other systems, but also opens up opportunities for using pyrrolidinyl PNA in various applications such as intracellular RNA sensing, specific gene detection, and antisense and antigene therapy.

Ligand-Phospholipid Conjugation: A Versatile Strategy for Developing Long-Acting Ligands That Bind to Membrane Proteins by Restricting the Subcellular Localization of the Ligand

We hypothesized that if drug localization can be restricted to a particular subcellular domain where their target proteins reside, the drugs could bind to their target proteins without being metabolized and/or excreted, which would significantly extend the half-life of the corresponding drug-target complex. Thus, we designed ligand-phospholipid conjugates in which the ligand is conjugated with a phospholipid through a polyethylene glycol linker to restrict the subcellular localization of the ligand in the vicinity of the lipid bilayer. Here, we present the design, synthesis, pharmacological activity, and binding mode analysis of ligand-phospholipid conjugates with muscarinic acetylcholine receptors as the target proteins. These results demonstrate that ligand-phospholipid conjugation can be a versatile strategy for developing long-acting ligands that bind to membrane proteins in drug discovery.

Highly efficient synthesis of monodisperse poly(ethylene glycols) and derivatives through macrocyclization of oligo(ethylene glycols)

A macrocyclic sulfate (MCS)-based approach to monodisperse poly(ethylene glycols) (M-PEGs) and their monofunctionalized derivatives has been developed. Macrocyclization of oligo(ethylene glycols) (OEGs) provides MCS (up to a 62-membered macrocycle) as versatile precursors for a range of monofunctionalized M-PEGs. Through iterative nucleophilic ring-opening reactions of MCS without performing group protection and activation, a series of M-PEGs, including the unprecedented 64-mer (2850Da), can be readily prepared. Synthetic simplicity coupled with versatility of this new strategy may pave the way for broader applications of M-PEGs. Macrocycles make synthesis easier: Convenient macrocyclization of the OEGs provides versatile macrocyclic sulfates. These compounds are cornerstones for both monofunctionalization of OEGs and highly efficient synthesis of monodisperse PEGs and derivatives, including an unprecedented 64-mer.
