  Exploring Left-Hand-Side substitutions in the benzoxazinone series of 4-amino-piperidine bacterial type IIa topoisomerase inhibitors

  摘要：

  An SAR survey at the C-6 benzoxazinone position of a novel scaffold which inhibits bacterial type IIa topoisomerase demonstrates that a range of small electron donating groups (EDG) and electron withdrawing groups (EWG) are tolerated for antibacterial activity. Cyano was identified as a preferred substituent that affords good antibacterial potency while minimizing hERG cardiac channel activity. (C) 2011 Elsevier Ltd. All rights reserved.

  isolates, but suffer from potent hERG inhibition (IC50= 3 μM for 1). We now disclose the finding that new analogues of 1 with an N-linked cyclic amide moiety attached to the ethyl bridge, such as 24m, retain the broad-spectrum antibacterial activity of 1 but show significantly less hERG inhibition (IC50= 31 μM for 24m) and higher free fraction than 1. One optimized analogue, compound 24l, showed moderate

  新型的细菌II型拓扑异构酶的非氟喹诺酮抑制剂（DNA促旋酶和拓扑异构酶IV）对于开发不受靶标介导的氟喹诺酮类交叉耐药性影响的新型抗菌剂具有重要意义。具有通过碳与乙基桥连接的双环芳族部分的氨基哌啶，例如1，通常显示出强效的广谱抗菌活性，包括对喹诺酮类耐药的菌株，但受到强的hERG抑制作用（IC 50 = 3μM/ 1） 。我们现在公开的发现是，新的1的类似物具有连接到乙基桥的N-连接的环状酰胺部分，例如24m，保留了其的广谱抗菌活性。1，但显示出显着更少的hERG抑制作用（24 m时IC 50 = 31μM）和高于1的游离分数。一种优化的类似物化合物24l在狗的大腿感染模型中在狗中表现出中等清除率，并且有望抵抗金黄色葡萄球菌。
