摘要
背景:特权基序在广泛的生物活性化合物中反复出现,这些化合物可达到不同的药物靶标和途径,并可能成为接触被忽视疾病领域潜在候选人的合适起点。 当前用于治疗这些疾病的疗法是基于缺乏所需功效,负担得起的合成方法并允许产生抗性菌株的方法的药物。 由于缺乏财务回报,只有极少数的制药公司一直在投资研究被忽视疾病的新疗法。 方法:基于2002年至2016年的文献检索,我们讨论了在对某些被忽略的疾病有效的化合物中,六个邻位特异的化合物(特别是邻苯二甲酰亚胺,靛红,吲哚,硫代半碳酰胺,噻唑和噻唑烷酮)如何特别出现。 结果:观察到人们尤其关注南美锥虫病,疟疾,结核病,血吸虫病,利什曼病,登革热,非洲昏睡病(人类非洲锥虫病-HAT)和弓形虫病。 可以证实,在ND中,抗锥虫活性和抗疟原虫活性是搜索最多的。 此外,硫半脲部分似乎是用途最广且经常探索的支架。 同样,在ND领域也已探索了邻苯二甲酰亚胺,靛红,噻唑和噻唑烷酮核。 结论:某些描述的化合物似乎是有前途的候选药物,而另一些可能代表了对新的先导化合物的研究的宝贵启示。
关键词: 特有的结构,邻苯二甲酰亚胺,isatine,吲哚,thiosemicarbazone,噻唑,噻唑烷酮抗原虫化学疗法,利什曼原虫病,疟原虫,锥虫,抗寄生虫药。
