Lipids & Polymers

Tos-PEG6-acid is a PEG linker containing a tosyl group and a terminal carboxylic acid. The hydrophilic PEG spacer increases solubility in aqueous media. The tosyl group is a very good leaving group for nucleophilic substitution reactions. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. HATU) to form a stable amide bond.

DSPE-PEG-Mannose, MW 5,000 is a PEG polymer containing DSPE and Mannose end groups. The hydrophobic properties of the DSPE allow for the encapsulation and congregation of other hydrophobic drugs. The hydrophilic PEG increases the water solubility of the overall compound allowing for the delivery of the drug. D-glucose increases solubility in aqueous media and increases the selectivity of the PEGylation reaction.

Tos-PEG2-acid is a PEG linker containing a tosyl group and a terminal carboxylic acid. The hydrophilic PEG spacer increases solubility in aqueous media. The tosyl group is a very good leaving group for nucleophilic substitution reactions. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. HATU) to form a stable amide bond.

(S, R, S)-AHPC-PEG2-Tos is a combination of a von Hippel-Lindau (VHL)-recruiting ligand and PEGylated crosslinker with a tosyl group. The tosyl group is a good leaving group for nucleophilic substitution reactions. (S, R, S)-AHPC-PEG2-Tos is useful for synthesis of PROTAC compounds and molecules for targeted protein degradation.

N-Boc-PEG10-alcohol is a PEG linker containing a hydroxyl group and Boc-protected amino group. The hydrophilic PEG spacer increases solubility in aqueous media. The hydroxyl group enables further derivatization or replacement with other reactive functional groups. The Boc group can be deprotected under mild acidic conditions to form the free amine.

DODAP (18:1) is an ionizable lipid with lower cytotoxicity and high transfection efficiency. DODAP is neutral at physiological pH, but acquires a positive charge inside the endosome due to the protonation of free amines when pH is lower than its pKa (<7).

TAP (14:0) is a cationic lipid that can be used for drug delivery, gene transfection, and vaccine delivery. It has been proven to be efficient for in vitro and in vivo transfection applications, which makes it one of the most widely used cationic lipids for gene transfection applications.

Azido-PEG19-azide is a click chemistry reagent with two terminal azide groups. The azide groups can react with alkyne, BCN, DBCO via Click Chemistry.
