Design, synthesis and biological evaluation of 2-substituted 3-hydroxy-6-methyl-4H-pyran-4-one derivatives as Pseudomonas aeruginosa biofilm inhibitors
Drug-resistant bacteria associated with biofilm formation are rapidly on the rise, requiring novel therapeutic options to combat biofilm induced drug-resistance. In this study, a class of 3-hydroxy-2-(phenylhydroxy-methyl)-6-methyl-4H-pyran-4-one derivatives (1a-1e) were found by screening of an in-house compound library to be potential Pseudomonas aeruginosa biofilm inhibitors. Thirty one novel 2-substituted

ruthenium(II)-arene complexes coordinated to maltol-derived ligands were prepared and their anticanceractivity against human tumor cell lines was studied. In addition, their hydrolysis behavior and reaction with 5′-GMP was tested and compared to the parent compound chlorido[2-methyl-3-(oxo-κO)-pyran-4(1H)-onato-κO4](η6-p-cymene)ruthenium(II) (Ru-maltol). Improved stability and in vitroanticanceractivity at maintained
制备了与麦芽酚衍生的配体配位的有机金属钌(II)-芳烃配合物,并研究了其对人肿瘤细胞系的抗癌活性。此外,它们的水解的行为和与5'-GMP的反应进行了测试,并与母体化合物chlorido [2-甲基-3-(氧代- κ ö) -吡喃-4-(1 ħ)-onato-κ Ò 4] (η 6 - p -cymene)合钌(II)(RU-麦芽酚)。与Ru-麦芽酚复合物相比,在保持GMP结合能力的情况下,观察到了改善的稳定性和体外抗癌活性。
