resistance remains an ongoing challenge. Our efforts in this regard continue to reveal new potential therapeutic agents with differing physicochemical properties while retaining the effective N,N-dichloroamine pharmacophore as the key antimicrobial warhead. In this Letter, we disclose agents containing polyol units as a water solubilizing group. These sulfonyl-polyol agents show broad spectrum bactericidal
不引起耐药性的抗微生物剂的发现和开发仍然是一个持续的挑战。我们在这方面的努力继续揭示出具有不同理化性质的新的潜在治疗剂,同时保留了有效的N,N-二氯胺药效基团作为关键的抗菌战斗部。在这封信中,我们公开了含有多元醇单元作为水溶性基团的试剂。这些磺酰基-多元醇剂显示出广谱的杀菌和杀病毒活性。这些化合物在中性pH值下对大肠杆菌的1h MBC值为16–512μg/ mL,对金黄色葡萄球菌为4–256μg/ mL ,1-h IC 50对腺病毒5的抗药性为4.5–32μM,对单纯疱疹病毒1的抗药性为0.7–3.0μM。先导化合物在组织培养物刺激性试验中进行测试,在测试的最高浓度下仅表现出最小的刺激性。
