Tetrahydropyrazolo[1,5-a]pyrimidine scaffold was identified as a hit series from a Mycobacterium tuberculosis (Mtb) whole cell high 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 at 100 mg/kg for 28 days. Thus, compound 9 is a potential candidate for inclusion in combination therapies for both drug-sensitive and drug-resistant TB.
四氢吡唑并[1,5-a]嘧啶骨架是在结核分枝杆菌(Mtb)全细胞高通量筛选(HTS)活动中鉴定出的一个有活性的系列。合成了该类别的一系列衍生物,以评估它们的构效关系(SAR)和构性关系(SPR)。化合物9在小鼠体内具有良好的药物代谢动力学特征,并在小鼠疗效模型中表现出强大的体内活性,以100mg/kg的剂量每天口服给药感染小鼠28天,可使Mtb的CFU减少3.5个对数。因此,化合物9是用于敏感和耐药结核病联合治疗的潜在候选药物。
