Two series of ten chalcones and ten aurones, where ferrocene replaces the C ring and with diverse substituents on the A ring were synthesized. The compounds were tested against two antibiotic-sensitive bacterial strains, E. coli ATCC 25922 and S. aureus ATCC 25923, and two antibiotic-resistant strains, S. aureus SA-1199B and S. epidermidis IPF896. The unsubstituted compound and those with methoxy substitution showed an inhibitory effect on all bacterial strains at minimum inhibitory concentrations ranging between 2 and 32 mg L−1. For four of these compounds, the effect was bactericidal, as opposed to bacteriostatic. The corresponding organic aurones did not show growth inhibition, underscoring the role of the ferrocene group. The methoxy-substituted aurones and the unsubstituted aurone also showed low micromolar (IC50) activity against MRC-5 non-tumoral lung cells and MDA-MB-231 breast cancer cells, suggesting non-specific toxicity.
合成了两个系列的十种
查耳酮和十种醛酮,其中
二茂铁取代了 C 环,A 环上的取代基多种多样。这些化合物针对两种抗生素敏感菌株(大肠杆菌 A
TCC 25922 和
金黄色葡萄球菌 A
TCC 25923)和两种抗生素耐药菌株(
金黄色葡萄球菌 SA-1199B 和表皮葡萄球菌 IPF896)进行了测试。未取代的化合物和甲氧基取代的化合物对所有细菌菌株都有抑制作用,最低抑制浓度为 2 至 32 mg L-1。其中四种化合物具有杀菌作用,而不是抑菌作用。相应的有机醛酮没有显示出生长抑制作用,这突出了
二茂铁基团的作用。甲氧基取代的醛酮和未取代的醛酮对 MRC-5 非肿瘤肺细胞和
MDA-MB-231 乳腺癌细胞也显示出较低的微摩尔(IC50)活性,表明其具有非特异性毒性。
