DSPE-PEG2000-OH
Based on 1 publication(s) in Google Scholar
DSPE-PEG2000-OH is an absorption enhancer. DSPE-PEG2000-OH reduces the expression levels of ZO-1 and Occludin. DSPE-PEG2000-OH enhances the pulmonary absorption of poorly absorbable macromolecules via the paracellular pathway without altering pulmonary membrane fluidity.

Biological Activity
DSPE-PEG2000-OH (1% (w/v); 20 min) does not alter the fluidity of isolated rat lung membrane vesicles, as measured by fluorescence polarization using DPH and TMA-DPH probes[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
DSPE-PEG-OH (0.1-1.0% (w/v); intratracheal administration; single dose; 1.0% (w/v); intratracheal administration; once weekly; for 2 consecutive weeks) does not induce significant local pulmonary membrane damage in brown rats (rats) at doses up to 1.0% (w/v), whether administered as a single intratracheal dose or once weekly for 2 consecutive weeks[1].

Result:Showed no obvious lung tissue damage compared to PBS control at all tested single doses, unlike positive control NaDC which caused significant tissue changes.
Exhibited no statistically significant difference in BALF protein and lactate dehydrogenase (LDH) levels compared to PBS control at 4 h post single dose administration.
Showed no statistically significant difference in BALF protein and LDH levels compared to PBS control after 2 consecutive weekly doses of 1.0% (w/v), unlike positive control NaDC which caused a dramatic increase in both markers.
