Application
18:0 PE-DTPA (Gd) has been used:
- as a component of Gadolinium-liposome preparation
- in the nanodics preparation for nuclear magnetic resonance (NMR) studies
- in construction of cysteine-arginine-glutamic acid-lysine alanine (CREKA) based peptide amphiphile micelles (PAMs) for the magnetic resonance imaging (MRI) studies
- as a spin-labeled lipid for supported lipid bilayer incorporation for cryo transmission electron microscopy studies
Biochem/physiol Actions
1,2-distearoyl-sn-glycero-3-phosphoethanolamine-N-diethylenetriaminepentaacetic acid (gadolinium salt) (18:0 PE-DTPA (Gd)) phospholipid based liposomes are useful in magnetic resonance imaging (MRI) and multimodal imaging. Apart from being a MRI contrast agent, PE-DTPA (Gd) liposome is also flexible for modification for binding different targets using copper–free click–chemistry methodology.
General description
1,2-distearoyl-sn-glycero-3-phosphoethanolamine-N-diethylenetriaminepentaacetic acid (gadolinium salt) (18:0 PE-DTPA (Gd)) are sparing soluble in alcohol and well soluble in a solvent mixture consisting of chloroform and methanol in the ratio of 4:1, v/v. 18:0 PE-DTPA (Gd) is a synthetic phospholipid derivative ethanolamine. The DTPA is attached to gadolinium ion.

Toll-like receptor 2 (TLR2) initiates potent immune responses by recognizing diacylated and triacylated lipopeptides. Its ligand specificity is controlled by whether it heterodimerizes with TLR1 or TLR6. We have determined the crystal structures of TLR2-TLR6-diacylated lipopeptide, TLR2-lipoteichoic acid, and TLR2-PE-DTPA

Gadolinium (Gd)-based contrast agents are extensively used for magnetic resonance imaging (MRI). Liposomes are potential nanocarrier-based biocompatible platforms for development of new generations of MRI diagnostics. Liposomes with Gd-complexes (Gd-lip) co-encapsulated with thrombolytic agents can serve both for imaging and
