through-put screening (HTS) campaign. A series of derivatives of this class were synthesized to evaluate their structure-activity relationship (SAR) and structure-property relationship (SPR). Compound 9 had a promising in vivo DMPK profile in mouse and exhibited potent in vivo activity in a mouse efficacy model, achieving a reduction of 3.5 log CFU of Mtb after oral administration to infected mice once a day
从结核分枝杆菌(Mtb)全细胞高通量筛选(HTS)活动中鉴定了四氢吡唑并[1,5-a]嘧啶支架是一个热门系列。合成了这类的一系列衍生物,以评估它们的结构-活性关系(SAR)和结构-性质关系(SPR)。化合物9在小鼠中具有有希望的体内DMPK谱,并且在小鼠功效模型中表现出有效的体内活性,在以100 mg / kg的剂量每天口服一次给予感染小鼠28天后,实现了Mtb的3.5 log CFU降低。因此,化合物9是药物敏感性和耐药性TB的联合疗法中潜在的候选药物。
