A series of new ligands has been prepared that incorporate electron-poor aromatic moieties (dpqMe and dpqPh chromophores) into tetraazacyclododecane or triazacyclononane based complex structures, and the time-dependent photophysical properties of their Eu(iii) and Tb(iii) complexes evaluated for the selective and rapid ratiometric analysis of urate in diluted serum solution, together with mechanistic studies probing the nature of the intermediate exciplex and the excited state dynamics using transient absorption spectroscopy.

Natural compounds' derivatives as lead structures could effectively solve plant disease problems. In this article, amide compounds and amide ester compounds were synthetized through ferulic acid as the parent nucleus structure, and their biological activities in vitro and in vivo were evaluated. Compound 1q was screened out as the one with the best activity performance toward Xanthomonas axonopodis pv.

Focal cortical dysplasia (FCD) II is a cortical malformation characterized by cortical architectural abnormalities, dysmorphic neurons, with or without balloon cells. Here, we systematically explored the pathophysiological role of the GATOR1 subunit NPRL3 variants including a novel mutation from iPSCs derived from one FCD II patient. Three FCD II children aged 0.

Sesamol (SES) and linalool (LIN) are aromatic compounds that have neuroprotective effects. The main purpose of this study is to evaluate the anxiolytic activity of LIN and SES co-treatment on Swiss albino mice and analyze its possible mechanism through in silico study. In this sense, the mice were given the gamma-aminobutyric acid type A receptors (GABA) agonist diazepam (DZP; 3 mg/kg, p.

Ferroptosis is regarded as a promising cancer therapeutic target. As a major bioactive compound from traditional Chinese medicine (TCM) herb Aiton, oxymatrine (OMT) can depress inflammatory factors, reduce iron deposition, and suppress the hub gene or protein expression involved in ferroptosis and inflammation. Additionally, OMT can control collagen deposition in the liver and has a therapeutic effect on liver cancer.

Inhibition of Bruton's tyrosine kinase (BTK) has proven to be highly effective in the treatment of B-cell malignancies such as chronic lymphocytic leukemia (CLL), autoimmune disorders, and multiple sclerosis. Since the approval of the first BTK inhibitor (BTKi), Ibrutinib, several other inhibitors including Acalabrutinib, Zanubrutinib, Tirabrutinib, and Pirtobrutinib have been clinically approved. All are covalent active site inhibitors, with the exception of the reversible active site inhibitor Pirtobrutinib.
