Enhancement of Platelet Aggregation by Ursolic Acid and Oleanolic Acid [PDF]

open access: yesBiomolecules & Therapeutics, 2014
The pentacyclic triterpenoid ursolic acid (UA) and its isomer oleanolic acid (OA) are ubiquitous in food and plant medicine, and thus are easily exposed to the population through natural contact or intentional use. Although they have diverse health benefits, reported cardiovascular protective activity is contentious. In this study, the effect of UA and

Three Oleanolic Acid Glycosides from the Seeds of

open access: yesNatural Product Communications, 2007
From the seeds of Achyranthes aspera three triterpenoid glycosides were isolated and their structures elucidated on the basis of NMR spectroscopic, mass spectrometric and degradative studies as α-L-rhamnopyranosyl-(1→4)-(β-D-glucopyranosyluronic acid)-(1→

Spatial Orientation‐Dependent Double Hydrogen Bond/Photoredox Cooperative Catalysis in Metal–Organic Frameworks

open access: yesAngewandte Chemie, Volume 138, Issue 32, 3 August 2026.
We report a heterogeneous double hydrogen bond/photoredox synergistic catalysis, wherein the flexibility and spatial orientation of catalytic centers, rather than catalyst activity, play a dominant role in catalytic performance. ABSTRACT Catalyst activity is typically the primary priority in designing a catalytic system. The higher catalyst activity is
