  Development of potent and selective Plasmodium falciparum calcium-dependent protein kinase 4 (PfCDPK4) inhibitors that block the transmission of malaria to mosquitoes

  摘要：

  Malaria remains a major health concern for a large percentage of the world's population. While great strides have been made in reducing mortality due to malaria, new strategies and therapies are still needed. Therapies that are capable of blocking the transmission of Plasmodium parasites are particularly attractive, but only primaquine accomplishes this, and toxicity issues hamper its widespread use. In this study, we describe a series of pyrazolopyrimidine- and imidazopyrazine-based compounds that are potent inhibitors of PfCDPK4, which is a calcium-activated Plasmodium protein lcinase that is essential for exflagellation of male gametocytes. Thus, PfCDPK4 is essential for the sexual development of Plasmodium parasites and their ability to infect mosquitoes. We demonstrate that two structural features in the ATPbinding site of PfCDPK4 can be exploited in order to obtain potent and selective inhibitors of this enzyme. Furthermore, we demonstrate that pyrazolopyrimidine-based inhibitors that are potent inhibitors of the in vitro activity of PfCDPK4 are also able to block Plasmodium falciparum exflagellation with no observable toxicity to human cells. This medicinal chemistry effort serves as a valuable starting point in the development of safe, transmission-blocking agents for the control of malaria. (C) 2014 Elsevier Masson SAS.

  Development of an Orally Available and Central Nervous System (CNS) Penetrant Toxoplasma gondii Calcium-Dependent Protein Kinase 1 (TgCDPK1) Inhibitor with Minimal Human Ether-a-go-go-Related Gene (hERG) Activity for the Treatment of Toxoplasmosis

  摘要：

  New therapies are needed for the treatment of toxoplasmosis, which is a disease caused by the protozoan parasite Toxoplasma gondii. To this end, we previously developed a potent and selective inhibitor (compound 1) of Toxoplasma gondii calcium-dependent protein kinase 1 (TgCDPK1) that possesses antitoxoplasmosis activity in vitro and in vivo. Unfortunately, 1 has potent human ether-a-go-go-related gene (hERG) inhibitory activity, associated with long Q-T syndrome, and consequently presents a cardiotoxicity risk. Here, we describe the identification of an optimized TgCDPK1 inhibitor 32, which does not have a hERG liability and possesses a favorable pharmacokinetic profile in small and large animals. 32 is CNS-penetrant and highly effective in acute and latent mouse models of T. gondii infection, significantly reducing the amount of parasite in the brain, spleen, and peritoneal fluid and reducing brain cysts by >85%. These properties make 32 a promising lead for the development of a new antitoxoplasmosis therapy.

  Toxoplasmosis is a disease of prominent health concern that is caused by the protozoan parasite Toxoplasma gondii. Proliferation of T. gondii is dependent on its ability to invade host cells, which is mediated in part by calcium-dependent protein kinase 1 (CDPK1). We have developed ATP competitive inhibitors of TgCDPK1 that block invasion of parasites into host cells, preventing their proliferation. The presence of a unique glycine gatekeeper residue in TgCDPK1 permits selective inhibition of the parasite enzyme over human kinases. These potent TgCDPK1 inhibitors do not inhibit the growth of human cell lines and represent promising candidates as toxoplasmosis therapeutics.
