AI Article Synopsis

  • Five new lignanamides and ten known amides were extracted from the roots' chloroform extract, with new compounds identified through NMR and mass spectrometry.
  • The absolute configuration of one compound was determined using ECD experiments and quantum mechanical calculations.
  • The anti-inflammatory effects of these compounds were tested on macrophages, showing that all reduced nitric oxide levels, while one compound did not significantly affect IL-10 levels, indicating potential anti-inflammatory properties.

Article Abstract

Five new lignanamides (-) and ten known amides (-) were isolated from the chloroform extract of roots. The structures of the new compounds were elucidated via analysis of NMR spectroscopic and mass spectrometry data and known structures by comparison with data from the literature. Compound had its absolute configuration established through ECD experiments, NMR calculations and quantum mechanical calculations. The anti-inflammatory activity of compounds (-) was assessed on RAW 264.7 macrophages. All the tested compounds reduced nitric oxide levels. In the cytokine quantification assays, only compound did not significantly reduce IL-10 levels. Moreover, compounds - and also reduced IL-1β levels. These results suggest the anti-inflammatory potential of these compounds.

is known for its potential antioxidant and anti-inflammatory properties, attributed to triterpenes, flavonoids, and tannins. This study aimed to optimise the extraction process for aerial parts of using vortex extraction. A Box-Behnken experimental design coupled with response surface methodology was employed to evaluate the effects of three independent variables: sample-to-solvent ratio, velocity, and temperature.

Chrysoeriol: a natural RANKL inhibitor targeting osteoclastogenesis and ROS regulation for osteoporosis therapy.

Naunyn Schmiedebergs Arch Pharmacol

The Key Laboratory of Spine and Spinal Cord Disease of Jiangxi Province, Nanchang, 330006, China.

Chrysoeriol (CHE) is a naturally occurring compound with established anti-inflammatory and anti-tumor effects. This study examines its potential role in regulating osteoclast differentiation and activity, both of which are crucial for bone remodeling. Computational docking revealed high binding affinity between CHE and RANKL, specifically at the Lys-181 residue of RANKL, suggesting potential inhibitory interactions on osteoclastogenesis.

Metabotropic glutamate (mGlu) receptors are candidate drug targets for therapeutic intervention in Parkinson's disease (PD). Here we focused on mGlu3, a receptor subtype involved in synaptic regulation and neuroinflammation. mGlu3 mice showed an enhanced nigro-striatal damage and microglial activation in response to 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP).

Pathogenic mechanisms of immune checkpoint inhibitor (ICI)-associated retinal and choroidal adverse reactions.

Am J Ophthalmol

January 2025

Department of Ophthalmology and Visual Sciences, Kellogg Eye Center, University of Michigan, Ann Arbor, MI. Electronic address:

Purpose: To summarize and categorize postulated mechanisms of immune checkpoint inhibitor (ICI)-mediated retinal and choroidal inflammation and discuss resulting implications for evaluation and management of these adverse reactions.

Design: Targeted literature review with interpretation and perspective Methods: We performed a review of selected literature describing immune-mediated retinal and choroidal adverse reactions associated with ICI therapy, synthesizing and categorizing the likely underlying pathogenic mechanisms. Based on these mechanistic categories, we provide perspective on a rational approach to the evaluation of patients with ICI-associated inflammatory disorders of the retina and choroid.

This study aimed to define the antitumor effect of ethanolic extract of Pistacia vera leaves (PEE) toward breast cancer both in vitro and in vivo using dimethyl-benz(a)anthracene (DMBA)-induced breast tumor in adult female rats. PEE showed a potent antioxidant effect toward both DPPH (1,1-diphenyl-2-picrylhydrazyl) and ABTS (2,2'-azino-bis(3-ethylbenzthiazoline-6-sulphonic acid) radicals with IC values of 72.6 and 107.
