Several novel series of nitrile-containing fluoroquinolones with weakly basic amines are reported which have reduced potential for hERG (human ether-a-go-go gene) channel inhibition as measured by the dofetilide assay. The new fluoroquinolones are potent against both Gram-positive and fastidious Gram-negative strains, including Methicillin resistant Staphylococcus aureus and fluoroquinolone-resistant
据报道,几种新的含弱碱性胺类的含腈氟喹诺酮类药物具有减少的hERG(人醚-go-go-go基因)通道抑制作用的潜力,如多芬替利试验所测。新的氟喹诺酮类药物对革兰氏阳性和革兰氏阴性菌株均有效,包括耐甲氧西林的金黄色葡萄球菌和耐氟喹诺酮的肺炎链球菌。通过克隆形成性测试,几种类似物还显示出较低的人类遗传毒性潜力。具有良好的体外活性和体外安全性的化合物22和37(分别命名为PF-00951966和PF-02298732)在大鼠中也显示出良好的药代动力学特性。
