Usage

Description

Azido-PEG2-acid is a PEG linker containing an azide group with a terminal carboxylic acid. The hydrophilic PEG spacer increases solubility in aqueous media. The azide group can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond.

Synthesis of nucleobase-functionalized carbon nanotubes and their hybridization with single-stranded DNA

For the first time ssDNA (25-aptamer of mixed dA, dT, dG, and dC) was wrapped around functionalized single-walled carbon nanotubes (SWCNTs), whose external surfaces were attached to multiple triazole-(ethylene glycol)-dA ligands. This method of hybridization involved the formation of hydrogen bonds between dT of ssDNA and dA of functionalized SWCNTs. It deviates from the reported π-π stacking between the nucleobases of DNA and the external sidewalls of nanotubes. The structural properties of the functionalized SWCNTs and its ssDNA complex were characterized by spectroscopic (including CD and Raman), thermogravimetric, and microscopic (TEM) methods. The results thus obtained establish a new platform of DNA delivery by use of nanotubes as a new vehicle with great potential in biomedical applications and drug development.

Synthesis of KUE-siRNA Conjugates for Prostate Cancer Cell-Targeted Gene Silencing

The delivery of siRNAs to selectively target cells poses a great challenge in RNAi-based cancer therapy. The lack of suitable cell-targeting methods seriously restricts the advance in delivering siRNAs to extrahepatic tissues. Based on prostate-specific m
