As part of an ongoing effort to develop new thalidomide analogues as antiinflammatory lead-candidates, this paper describes the synthesis and antiinflammatory activity of novel N-phenyl-phthalimide functionalized derivatives (4a-d, 5a,b, 6a,b). The target compounds were assayed in an acute lung inflammatory model and all compounds were able to inhibit TNF-alpha production and subsequent neutrophil recruitment in the LPS-acute lung inflammatory model.

Phenylketonuria is a genetic disorder characterized by high phenylalanine levels, the main toxic metabolite of the disease. Hyperphenylalaninemia can cause neurological impairment. In order to avoid this symptomatology, patients typically follow a phenylalanine-free diet supplemented with a synthetic formula that provides essential amino acids, including L-carnitine.

Introduction/objectives: Sjogren's syndrome (SS) is a chronic inflammatory and difficult-to-treat autoimmune disease. Timosaponin AIII (TAIII), a plant-derived steroidal saponin, effectively inhibits cell proliferation, induces apoptosis, and exhibits anti-inflammatory properties. This study explored the mechanisms of action of TAIII in SS treatment by studying gut microbiota and short-chain fatty acids (SCFAs) using fecal metabolomics.

Emerging evidence highlights the significance of peripheral inflammation in the pathogenesis of Parkinson's disease (PD) and suggests the gut as a viable therapeutic target. This study aimed to explore the neuroprotective effects of the probiotic formulation VSL#3 and its underlying mechanism in a PD mouse model induced by MPTP. Following MPTP administration, the striatal levels of dopamine and its metabolites, as along with the survival rate of dopaminergic neurons in the substantia nigra, were significantly reduced in PD mice.

Selenium is an essential element with various industrial and medical applications, hence the current considerable attention towards the genesis and utilization of SeNPs. SeNPs and other nanoparticles could be achieved via physical and chemical methods, but these methods would not only require expensive equipment and specific reagents but are also not always environment friendly. Biogenesis of SeNPs could therefore be considered as a less troublesome alternative, which opens an excellent window to the selenium and nanoparticles' world.

We have recently shown that fluoxetine (FX) suppressed polyinosinic-polycytidylic acid-induced inflammatory response and endothelin release in human epidermal keratinocytes, via the indirect inhibition of the phosphoinositide 3-kinase (PI3K)-pathway. Because PI3K-signaling is a positive regulator of the proliferation, in the current, highly focused follow-up study, we assessed the effects of FX (14 µM) on the proliferation and differentiation of human epidermal keratinocytes. We found that FX exerted anti-proliferative actions in 2D cultures (HaCaT and primary human epidermal keratinocytes [NHEKs]; 48- and 72-h; CyQUANT-assay) as well as in 3D reconstructed epidermal equivalents (48-h; Ki-67 immunohistochemistry).
