We evaluated the antimicrobial activity of 25 monoketone curcuminoids (MKCs) against a representative panel of cariogenic bacteria in terms of their minimum inhibitory concentration (MIC) values. Curcumin A (10) displayed promising activity against Streptococcus mutans (MIC = 50 μg/ml) and Streptococcus mitis (MIC = 50 μg/ml) as well as moderate activity against S. sanguinis (MIC = 100 μg/ml), Lactobacillus
我们根据最低抑菌浓度 (MIC) 值评估了 25 种单酮类姜黄素 (MKC) 对一组有代表性的致龋菌的抗菌活性。姜黄素 A (10) 对变形链球菌 (MIC = 50 μg/ml) 和缓和链球菌 (MIC = 50 μg/ml) 显示出有前景的活性,以及对血链球菌 (MIC = 100 μg/ml)、干酪乳杆菌的中等活性(MIC = 100 μg/ml) 和唾液链球菌 (MIC = 200 μg/ml)。结果表明化合物 10 的活性高于其双β-二酮类似物。此外,化合物 3a(1,5-双(4-甲基苯基)戊烷-3-one)和 7b(1,5-双(4-溴苯基)戊烷-3-醇)对 S. mitis 具有中等活性(MIC = 100 μg/ml)和唾液链球菌(MIC = 200 μg/ml)。
