Objective:
To investigate the main chemical components and the anti-inflammatory activity of extracts of Adelia ricinella L. aerial parts.
Methods:
Three extracts obtained by soxhlet extraction and ethanol/water mixtures were evaluated in their chemical composition by UPLC-DAD-MS/MS. The in vitro anti-inflammatory activity of the prepared extracts was assessed through three different assays: COX-1 and COX-2 enzymatic inhibition, cell-based COX assays on RAW264.7 macrophages (ATCC) measuring the COX-2 protein expression by Western blot and the measurement of the PGE2 concentration in the supernatants of the culture medium. Also was determinate the effect of the three extracts on the RAW 264.7 cell viability.
Key Findings:
Few differences in the phytochemical profile were found between the three prepared extracts, identifying a blend of thirteen flavonoids derived from luteolin and apigenin, with orientin as main constituent. Plant extracts (alcoholic and aqueous) did not affect the macrophage cell viability (IC50 > 256 μg/ml) and significantly reduced COX-1 and COX-2 enzyme activities. Additionally, COX-2 expression and PGE2 release were suppressed after 24 h of LPS stimulation and treatment with plant extracts (8-64 µg/ml).
Conclusions:
A. ricinella extracts showed the ability to reduce the inflammatory effect exerted by LPS in murine macrophages. However, further studies should confirm their anti-inflammatory activity.

01:30Adrenergic Agonists: Therapeutic Uses
Emergency and Intensive Care Unit (ICU) applications: Pressor agents increase blood pressure, heart rate, and contractility in shock and organ failure situations. Dopamine can induce vasodilation and stimulate adrenoceptors. Endogenous catecholamines are effective in treating cardiogenic shock. α2-agonists like clonidine can reverse anesthesia-induced hypertension.

01:25Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...
