As a continuation of the recently communicated discovery of oximinoarylsulfonamides as potent inhibitors of HIV-1 aspartyl protease, compounds bearing pyridylmethyl substituents at P3 were designed and synthesized. Potent analogs in this series provided low single-digit nanomolar EC50 values against both wild-type HIV and resistant mutant virus (A17), attenuated some 3- to 12-fold in the presence of
作为最近传达的氧亚氨基芳基磺酰胺作为HIV-1天冬氨酰蛋白酶的有效抑制剂的发现的继续,设计并合成了在P3带有吡啶基甲基取代基的化合物。该系列中的强效类似物对野生型HIV和抗性突变病毒(A17)均具有较低的个位数纳摩尔EC50值,在50%的人血清中可减弱约3至12倍。当与等量的利托那韦(每只5mg / kg)在大鼠中共同给药时,该系列化合物的药代动力学结果显示良好至极好的暴露,平均AUC> 8 microg h / mL。狗的相似剂量导致血浆水平显着降低(平均AUC <2 microg h / mL)。3-吡啶基甲基类似物30的总体暴露最佳(大鼠AUC = 7.1微克h / mL,狗AUC = 4.9微克h / mL),但是,
