Abstract Doxorubicin (DOX) is widely used in cancer treatment but the dose‐related toxicity of DOX on organs including liver limit its use. Therefore, there great interest combining with natural compounds antioxidant properties to reduce and increase drug efficacy. Esculetin a coumarin derivative biological encompassing anti‐inflammatory activities. In light these properties, this study was meticulously crafted investigate potential esculetin preventing doxorubicin (DOX)‐induced hepatotoxicity Sprague‐Dawley rats. The rats were divided into total six groups: control group, group (administered at cumulative dose 5 mg/kg intraperitoneally every other day for 2 weeks), E50 50 day), E100 100 day) combined groups (DOX + E100) which administered together DOX. treatments, both alone combination E50, manifested reduction catalase (CAT mRNA) levels comparison group. Notably, enzymatic activities superoxide dismutase (SOD), CAT, glutathione peroxidase (GPx) witnessed significant decreases treated Moreover, induced statistically elevation malondialdehyde (MDA) levels, coupled concurrent decrease (GSH) levels. Additionally, molecular docking studies conducted. However, further are needed confirm hepatoprotective precisely elucidate mechanisms action.

This research aims to design and synthesize novel derivatives of Cefuroxime evaluate their antibacterial effectiveness in comparison decrease resistance. Schotten Baumann's reaction synthesizes anhydride from acyl chlorides carboxylate anion. sodium was reacted with benzoyl chloride, 4-bromobenzoyl 4-nitrobenzoyl chloride make derivatives. The were characterized using spectral analysis. Antimicrobial activity, cytotoxicity, in-silico molecular docking nine different class (Penicillin Binding Proteins) PBPs, ADMET analysis assessed for the analogs. Three molecules, Cef-1, Cef-2, Cef-3, are synthesized In various organisms, outperformed antimicrobial activity. many Cef-1 has highest zone inhibition. Cef-3 inhibit Klebsiella pneumoniae better than Cef-2 Cefuroxime. greatest Cef-2-induced inhibition Salmonella Typhimurium 29.33 ± 0.47 mm. Significant susceptibility test activity observed lower inhibitory concentration (12.5 μg/ml) compared across species. Compound cytotoxicity is low, according research. consensus scores show that all bind cefuroxime. According results study, strongest correlation PBP1a, PBP2a, PBP3, PBP4, PBP6, whereas a stronger association PBP1b, PBP2b, PBP2x, PBP5. Like greater affinity PBP2x. Docking indicated drugs bound Cefuroxime, indicating superior efficacy. studies showed oral bioavailability increased by increasing lipophilicity score 0.17 cefuroxime 0.11.
