The aim of this study was to synthesize three nitro substituted chalcones and to evaluate their anti-inflammatory activity in the model of carrageenan induced edema in rats. The nitro chalcone were prepared by aldol condensation using of mechanical agitation and environmentally friendly solvents with 72-73% yields in approximately 2h. The three structures were evaluated on biological activity at dose of 200mg/kg and they showed anti-inflammatory protective effect by both oral and intraperitoneal administration, this effect was time dependent.

We aimed to investigate the wound-healing, antioxidant, and anti-inflammatory effects of pterostilbene (PTS) on human gingival fibroblasts (GF). Different concentrations of PTS were applied to GFs and cell viability was evaluated by MTT assay. GFs were stimulated by lipopolysaccharide (LPS) and the study groups were determined as LPS, LPS + 1 μM PTS, LPS + 10 μM PTS, and control.

Parkinson's disease (PD) stands as the sec most prevalent incapacitating neurodegenerative disorder characterized by deterioration of dopamine-producing neurons in the substantia nigra. Coenzyme Q10 (CoQ10) has garnered attention as a potential antioxidant, anti-inflammatory agent and enhancer of mitochondrial complex-I activity. This study aimed to examine and compare the effectiveness of liposomal and non-encapsulated CoQ10 in rotenone induced-PD mouse model over a 21-day treatment duration.

The blood flow, when restored clinically following a myocardial infarction (MI), disrupts the physiological and metabolic equilibrium of the ischemic myocardial area, resulting in secondary damage termed myocardial ischemia-reperfusion injury (MIRI). Reactive oxygen species (ROS) generation and inflammatory reactions stand as primary culprits behind MIRI. Current strategies focusing on ROS-scavenging and anti-inflammatory actions have limited remission of MIRI.

Flavonoids such as silibinin, hesperetin, and phloretin exhibit well-documented biological activities, including anti-inflammatory, cytoprotective, anticarcinogenic, and antioxidant effects. However, their clinical application remains limited due to challenges such as poor aqueous solubility, low bioavailability, and restricted intestinal absorption, which can significantly reduce their pharmacological efficacy. This review analyzed patents related to innovative pharmaceutical technologies for flavonoids.

Macrophages play a crucial role in the immune response during allograft rejection in organ transplantation. Therefore, our study aimed to explore the genomic features of macrophages in mouse heart transplants and use single-cell RNA sequencing to investigate Galectin-9 (Gal-9, Lgals9), a lectin that can mediate the activation and differentiation of immune cells through ligand-receptor interactions, and the effects of its regulation in transplantation. We discovered a new subset of macrophages called "Myoz2+ macrophages", which specifically expressed genes related to myocardial contraction.
