  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 .

  A method to access totally new analogues of tadalafil was explored, The Buchwald reaction was adapted and used to replace the methyl group of tadalafit by various aryl groups. Inhibition potencies on PDE5 of these analogues were determined and proved to be comparable to the one of tadalafil. Using the same route, compounds with the same level of activity but improved water solubility were produced by introducing a pyridine or a pyrimidine ring. This original route also opens access to new unpatented compounds. (c) 2006 Elsevier Ltd. All rights reserved.
