Studies of iridoid glycosides using liquid chromatography/electrospray ionization tandem mass spectrometry

, 2007
Fragmentation pathways of five iridoid glycosides have been studied by using electrospray ionization multi-stage tandem mass spectrometry (ESI-MSn). The first-stage MS data of the five iridoid glycosides were compared.

Protective Potentials of Natural Products Against Vascular Dementia: A Comprehensive Review of Experimental Studies

Phytotherapy Research, EarlyView.
ABSTRACT Vascular dementia (VaD), accounting for up to 20% of dementia cases globally, is primarily driven by chronic cerebral hypoperfusion (CCH), which leads to progressive cognitive impairment. Despite the increasing prevalence of VaD, effective treatments remain limited.

Gentiopicroside Regulates EGFR and Induces Its Lysosomal Degradation to Attenuate Heart Failure

Phytotherapy Research, EarlyView.
GPS attenuates pressure overload‐induced cardiac remodeling by promoting lysosomal degradation of EGFR. TAC‐induced EGFR accumulation activates AKT/ERK1/2 signaling and drives pathological cardiac hypertrophy, fibrosis, apoptosis, oxidative stress, and cardiac dysfunction. GPS promotes lysosome‐dependent EGFR degradation, thereby limiting excessive AKT/
