  Drug to Genome to Drug: Discovery of New Antiplasmodial Compounds

  摘要：

  The dominant strategy for discovery of new antimalarial drugs relies on cell-free assays on specific biochemical pathways of Plasmodium falciparum . However, it appears that screening directly on the parasite is a more rewarding approach. The "drug to genome to drug" approach consists of testing a small set of structural analogues of a drug acting on human proteins that have plasmodial orthologues. Both man and plasmodium possess cyclic nucleotide phosphodiesterases (PDEs) that are key players of cell homeostasis. We synthesized and tested 40 analogues of tadalafil, a human PDE5 inhibitor, on P. falciparum in culture and obtained potent inhibitors of parasite growth. We discuss the structure-activity relationships, which support the hypothesis that our compounds kill the parasite via inhibition of plasmodial PDE activity. We also prove that antiplasmodial derivatives inhibit the hydrolysis of cyclic nucleotides of the parasite, validating the cAMP/cGMP pathways as therapeutic targets against Plasmodium falciparum .

  支架探索对新型双重作用组蛋白脱乙酰酶和磷酸二酯酶5抑制剂治疗阿尔茨海默氏病的影响

  摘要：

  一种同时抑制磷酸二酯酶5（PDE5）和组蛋白脱乙酰基酶（HDAC）的新型系统治疗方法已被证实是治疗阿尔茨海默氏病（AD）的一种潜在的新型治疗策略。最近报道了带有西地那非核心的同类双重抑制剂，铅分子7已经在AD动物模型中证明了这种策略。由于脚手架可能在主要活动，ADME-Tox分析以及知识产权中发挥关键作用，因此我们探索了其他脚手架（基于vardenafil和tadalafil的核心），并评估了它们对关键参数（例如主要活动，渗透性，毒性和体内（海马的药代动力学和功能反应），以鉴定具有不同化学型的潜在替代铅分子，以进行体内测试。
