In the present study, a series of 2-(3'-substituted-2'-hydroxypropylamino)pyridines were synthesized and characterized by IR, 1H-NMR and elemental analysis. The compounds were investigated for anticonvulsant (150, 300 mg/kg) and cardiac activity. 2-(3'-Diethylamino-2'-hydroxypropylamino)pyridine 3 was found to exhibit the highest anticonvulsant activity. 2-(3'-Dimethylamino-2'-hydroxypropylamino)pyridine 2 and 2-[3'-(4''-nitrophenylamino)-2'-hydroxypropylamino]pyridine 6 were found to exhibit negative ionotropic activity. 2-(3'-Dimethylamino-2'-hydroxypropylamino)pyridine 2, 2-[3'-(4''-nitrophenylamino)-2'-hydroxypropylamino]pyridine 6 and 2-(3'-piperidino-2'-hydroxypropylamino)pyridine 8 were found to antagonize exhibit beta-adrenergic activity.

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.

Reduction-oxidation factor-1 or apurinic/apyrimidinic endonuclease 1 (Ref-1/APE1) is a crucial redox-sensitive activator of transcription factors such as NF-κB, HIF-1α, STAT-3 and others. It could contribute to key features of ocular neovascularization including inflammation and angiogenesis; these underlie diseases like neovascular age-related macular degeneration (nAMD). We previously revealed a role for Ref-1 in the growth of ocular endothelial cells and in choroidal neovascularization (CNV).

Translation initiation, which involves numerous protein factors and coordinated control steps, represents the most complicated process during eukaryotic translation. However, the roles of eukaryotic translation initiation factor (eIF) in filamentous fungi are not well clarified. In this study, we investigated the function of eIF2Bα in Aspergillus oryzae, an industrially important filamentous fungus.

AtbZIP69 overexpression in wheat significantly enhanced drought and low nitrogen tolerance by modulating ABA synthesis, antioxidant activity, nitrogen allocation, and transporter gene expression, boosting yield. In this study, we generated wheat plants with improved low nitrogen (LN) and drought tolerance by introducing AtbZIP69, a gene encoding a basic leucine zipper domain transcription factor, into the wheat cultivar Shi 4056. AtbZIP69 localized to the nucleus and activated transcription.
