Supercritical CO2 selectively extracted a series of 4-alkyl and 4-phenyl 5,7-dihydroxycoumarins from Mesua ferrea blossoms. Chemical modifications of the isolated compounds allowed us to confirm the structures elucidated by spectroscopic means and to prepare new derivatives amenable to SAR studies and potential pharmaceutical development. Biological investigations towards the screening on a number
超临界 CO2 从 Mesua ferrea 花中选择性提取了一系列 4-烷基和 4-苯基 5,7-二羟基香豆素。分离化合物的化学修饰使我们能够确认通过光谱手段阐明的结构,并制备适合 SAR 研究和潜在药物开发的新衍生物。对许多细菌菌株和恶性疟原虫进行筛选的生物学研究确定了化合物 1-9 作为弱抗原生动物剂和对耐药革兰氏阳性菌株的强效抗菌剂。
