  Discovery and Optimization of Isoquinoline Ethyl Ureas as Antibacterial Agents

  摘要：

  Our strategy to combat resistant bacteria consisted of targeting the GyrB/ParE ATP-binding sites located on bacterial DNA gyrase and topoisomerase IV and not utilized by marketed antibiotics. Screening around the minimal ethyl urea binding motif led to the identification of isoquinoline ethyl urea 13 as a promising starting point for fragment evolution. The optimization was guided by structure-based design and focused on antibacterial activity in vitro and in vivo, culminating in the discovery of unprecedented substituents able to interact with conserved residues within the ATP-binding site. A detailed characterization of the lead compound highlighted the potential for treatment of the problematic fluoroquinolone-resistant MRSA, VRE, and S. pneumoniae, and the possibility to offer patients an intravenous-to-oral switch therapy was supported by the identification of a suitable prodrug concept. Eventually, hERG K-channel block was identified as the main limitation of this chemical series, and efforts toward its minimization are reported.

  Acute myeloid leukemia (AML) is characterized by fast progression and low survival rates, in which Fms-like tyrosine kinase 3 (FLT3) receptor mutations have been identified as a driver mutation in cancer progression in a subgroup of AML patients. Clinical trials have shown emergence of drug resistant mutants, emphasizing the ongoing need for new chemical matter to enable the treatment of this disease

  急性髓细胞性白血病（AML）的特征是进展快，生存率低，其中已将Fms样酪氨酸激酶3（FLT3）受体突变确定为AML患者亚组中癌症进展的驱动程序突变。临床试验已显示出耐药突变体的出现，强调了对新化学物质的持续需求，以使该疾病得以治疗。在这里，我们介绍了已知的PKA抑制剂异喹啉磺酰胺H-89作为FLT3抑制剂的类似物的发现和拓扑结构-活性关系（SAR）研究。令人惊讶地，我们发现SAR与在PKA中观察到的H-89的结合模式不一致。匹配的分子对分析导致鉴定出高活性的亚纳摩尔氮杂吲哚作为新型的FLT3抑制剂。
