Human African trypanosomiasis is causing thousands of deaths every year in the rural areas of Africa. In this manuscript we describe the optimization of a family of phtalazinone derivatives. Phosphodiesterases have emerged as attractive molecular targets for a novel treatment for a variety of neglected parasitic diseases. Compound 1 resulted in being a potent TbrPDEB1 inhibitor with interesting activity
非洲人类锥虫病每年在非洲农村地区造成数千人死亡。在此手稿中,我们描述了酞菁酮衍生物家族的优化。磷酸二酯酶已成为一种有吸引力的分子靶标,可用于治疗多种被忽视的寄生虫病。化合物1导致作为一种有效的抑制剂TbrPDEB1用针对令人感兴趣的活性布氏锥虫在表型筛选。在急性体内小鼠疾病模型中对衍生物1进行了研究,但不幸的是,由于代谢稳定性低,它没有显示出任何功效。我们报道了结构修饰,以实现具有改善的代谢稳定性的化合物,同时保持针对TbrPDEB1和布氏锥虫。化合物14在小鼠和人微粒体中表现出良好的微粒体稳定性,并为以后的工作提供了良好的起点。
