MedKoo Cat#: 414874 | Name: DSPE
Featured

Description:

WARNING: This product is for research use only, not for human or veterinary use.

DSPE has been used in an FDA approved liposomal drug. It is the staring material for the synthesis of mPEG-DSPE, a widely used surface modifying amphiphilic molecule that keeps liposomes from interacting with blood components and provides a long circulation time for liposomes and other nanoparticles. DSPE has been explored to construct liposomes that are stable and long circulating in blood, but promptly release its content after ultrasound sonication.

Biological target:
1,2-Distearoyl-sn-glycero-3-phosphorylethanolamine (DSPE) is a phosphoethanolamine (PE) lipid that can be used in the synthesis of liposomes.
In vitro activity:
The release behaviors of DOX from DSPE-PEG-C60 micelles were consistent with the DSPE-PEG micelles, and it showed sustained release. There was lower cytotoxicity of DSPE-PEG-C60 micelles on normal cell lines (L02, H9c2, GES-1) than free DOX and DSPE-PEG micelles. In conclusion, the prepared DOX-loaded DSPE-PEG-C60 micelles have great promise for safe, effective tumor therapy.

In vivo activity:
Intrapulmonary delivery of these DSPE-PEG polymers significantly enhanced absorptions of poorly absorbed model drugs and did not induce serious damage to the pulmonary membranes of rats. These findings suggested that these DSPE-PEG polymers are potential for promoting absorptions of poorly absorbable macromolecules with no evidence of damage to the local pulmonary membranes of rats.
