preliminary studies of analogs of siderophores (microbial iron chelators) 2 and 20 that incorporate centers within the siderophore framework capable of generating potent electrophiles (iminium ions), hopefully after directed cellular recognition and uptake. Formation of N-aminals from trimelamol (3) and substituted hydroxamic acid 4 or 5was critical for the design and synthesis of the targets. In preliminary
当前,DNA指导的烷基化剂作为潜在的抗癌/抗微生物药物的作用受到广泛关注。临床上用作药物的大多数烷基化剂无特异性地破坏细胞中的DNA,这可能导致不良的毒性问题。通过靶向药物选择病原体或器官来最大程度地减少血清停留时间,可能会降低非选择性反应性的影响。本文介绍了铁载体(微生物铁螯合剂)2和20的类似物的合成和初步研究,这些类似物在铁载体框架内整合了能够产生强亲电试剂(亚胺离子)的中心,希望能在定向细胞识别和吸收后产生。由三甲蝶呤(3)和取代的异羟肟酸4或5形成N缩醛对于靶标的设计和合成至关重要。
