Abstract A new series of 12-benzyl matrinic amide/ethanamide derivatives were synthesized from matrinine ( 1 ) and evaluated for their anti-HCV activity, taking compound 2 as the lead. SAR revealed that the introduction of a suitable substituent at the N ′-end of matrinic amide might greatly enhance the potency. Among them, matrinic acid 17 and N ′-substituted matrinic amides 18a – d exhibited promising
摘要以苦参碱(1)为原料合成了一系列新的12-苄基马尿酰胺/乙酰胺衍生物,并以化合物2为主要成分对其抗HCV活性进行了评价。SAR显示,在母体酰胺的N'端引入合适的取代基可能会大大增强药效。其中,马黛酸17和N'-取代的马黛酰胺18a – d表现出有希望的效价,微摩尔EC 50值范围从1.03μmol/ L至7.54μmol/ L,SI范围从66至132更好。化合物17在体内显示出出色的PK和安全性,证明了良好的类药物特性。因此,已经选择了它用于进一步研究,其优点是减少了诱导耐药性突变的机会。
