Herein we report on the semisynthesis and biological evaluation of β-amino alcohol derivatives of the natural product totarol and other simple aromatic systems. All β-amino alcohol derivatives of totarol exhibited higher antiplasmodial activity than totarol [IC50: 11.69 μM (K1, chloroquine and multi-drug resistant strain), and 11.78 μM (D10, chloroquine sensitive strain)]—12e was the most active [IC50:
在这里,我们报告天然产物totarol和其他简单芳香体系的β-氨基醇衍生物的半合成和生物学评估。甲苯酚的所有β-氨基醇衍生物均具有比甲苯酚更高的抗血浆活性[IC 50:11.69μM (K1,氯喹和多药耐药菌株),而11.78μM(D10,对氯喹敏感的菌株)] — 12e活性最高[ IC 50:0.63μM(K1)和0.61μM(D10)]。苯基和萘基β-氨基醇衍生物的活性远低于其相应的totarol当量。相比于恶性疟原虫的D10菌株,大多数拓他酚的β-氨基醇衍生物对K1的活性更高。的趋势类似于已建立的芳基-氨基醇抗疟药甲氟喹的逆关系。已显示所选化合物会影响红细胞形态,抑制红细胞入侵并触发CQ积累。
