PATENT DESCRIPTION
[0001]    The invention relates to novel compounds of the formula I. The invention also concerns related aspects including processes for the preparation of the compounds, pharmaceutical compositions containing one or more compounds of the formula I and especially their use as medicaments to treat or prevent malaria infections or to treat or prevent other protozoal diseases like sleeping sickness, Chagas disease, amebiasis, giardiasis, trichomoniasis, toxoplasmosis, and leishmaniasis. 
       BACKGROUND OF THE INVENTION 
       [0002]    Numerous serious diseases affecting humans as well as domestic and livestock animal are caused by protozoal organisms such as kinetoplastida, apicomplexa, anaerobic protozoa, microsporidia and  plasmodium , for example. The clinically most relevant of these diseases is malaria. 
         [0003]    Malaria is one of the most serious and complex health problems affecting humanity in the 21 st  century. The disease affects about 300 million people worldwide, killing 1 to 1.5 million people every year. Malaria is an infectious disease caused by four species of the protozoan parasite  plasmodium, P. falciparum  being the most severe of the four. All attempts to develop vaccines against  P. falciparum  have failed so far. Therefore, therapies and preventive measures against malaria are confined to drugs. Various classes of antimalarial drugs exist. The most widely used are the quinoline antimalarials, e.g. chloroquine which has been an especially effective drug for both prophylaxis and therapy. However, resistance to many of the currently available antimalarial drugs is spreading rapidly, threatening people in areas where malaria is endemic. Reports of multi-drug resistant strains of malaria parasites render the search for new antimalarial agents especially urgent. 
         [0004]      P. falciparum  enters the human body by way of bites of the female anophelino mosquito (it may also be transmitted by blood transfusion from asymptotic donors; almost all infected blood components including red cells, platelet concentrates, white cells, cryoprecipitates and fresh plasma can transmit malaria). The  plasmodium  parasite initially populates the liver, and during later stages of the infectious cycle reproduces in red blood cells. During this stage, the parasite degrades hemoglobin and uses the degradation products as nutrients for growth. 
         [0005]    The limitations of the current antiprotozoal chemotherapeutic arsenal underscore the need for new drugs in this therapeutic area. The present invention relates to the identification of novel low molecular weight, non-peptidic, non-quinoline compounds of formula I which are useful in the treatment and/or prevention of protozoal infections, especially in the treatment and/or prevention of malaria, in particular  plasmodium falciparum  malaria.

         [0312]    The compounds of the formula I of the present invention may be prepared according to the procedures described herein, especially as described in the experimental part. 
         [0313]    In general, all chemical transformations can be performed according to well-known standard methodologies as described in the literature or as described in the procedures below. 
       Preparation of Compounds of Formula I: 
     Method A: 
       [0314]    
       
                 
         
             
             
         
       
     
         [0315]    The Boc-protected aminoacid 1 can be coupled with a tetrahydroisoquinoline derivative 2 by the help of a coupling/activating reagent such as TBTU in a solvent such as DCM, at rt in the presence of a base such as DIPEA, to give the intermediate 3. Boc-deprotection is usually achieved by reacting 3 with TFA in DCM to give the amine intermediate 4. Reductive amination with an aldehyde derivative 5 in a solvent such as DCM and in the presence of a reducing reagent such as sodium triacetoxyborohydride gives the expected secondary amine intermediate 6. Compound 6 can be acylated by a carboxylic acid 7 by the help of a coupling/activating reagent such as TBTU in a solvent such as DCM, at rt in the presence of a base such as DIPEA, to give the final compounds 8 of formula I. 
         [0316]    The compounds of formula I can also be prepared via method B and according to Scheme 2.

         [0318]    Reductive amination of an amino-acid 9 with an aldehyde derivative 10 in a solvent such as MeOH and in the presence of a reducing reagent such as sodium borohydride gives the expected secondary amine intermediate 11. Compound 11 can be acylated by an acyl chloride 12 in a solvent such as DCM in the presence of a base such as DIPEA, to give the amide intermediate 14. 
         [0319]    The acyl chloride can be generated by reaction of the corresponding carboxylic acid 7 with oxalyl chloride in the presence of few drops of DMF and in a solvent such as DCM. Saponification of the ester function using methods known in the art such as treatment with a base such as NaOH in solvent mixtures such as methanol/water or ethanol/water followed by acylation of the resulting acid 15 with a 1,2,3,4-tetrahydroisoquinoline derivative 16 with the help of a coupling/activating reagent such as TBTU in a solvent such as DCM in the presence of a base such as DIPEA provides the final compounds 17 of formula I.

         [0875]    In vitro antimalarial activity:  Plasmodium falciparum  in vitro assay In vitro activity against erythrocytic stages of  P. falciparum  is determined using a [ 3 H] hypoxanthine incorporation assay. One strain resistant to chloroquine and pyrimethamine ( P. falciparum  K1) is used in the assays, and all test compounds are compared for activity with the standard drugs chloroquine (sigma C6628) and artemisinin (sigma-36, 159-3). Compounds are diluted in DMSO to 1 mM and added to parasite cultures incubated in RPMI 1640 medium without hypoxanthine, supplemented with HEPES (5.94 g/L), NaHCO 3  (2.1 g/L), neomycin (100 U/mL), Albumax (5 g/L) and washed human red cells at 2.5% hematocrit (0.3% parasitaemia). Seven serial doubling dilutions of each drug are prepared in 96-well microtitre plates and incubated in a humidifying atmosphere at 37° C.; 4% CO 2 , 3% O 2 , 93% N 2 . 
         [0876]    After 48 h, 50 μl of [ 3 H] hypoxanthine (0.5 μCi) is added to each well of a plate. The plates are incubated for a further 24 h under the same conditions. The plates are then harvested with a Betaplate cell harvester (Wallac) and washed with distilled water. The dried filters are inserted into a plastic foil with 10 mL of scintillation fluid, and counted in a Betaplate liquid scintillation counter. IC 50  values are calculated from sigmoidal inhibition curves using Microsoft Excel. Inhibition activities (IC 50  values) of the 254 exemplified compounds are in the range of 1-423 nM with an average of 257 nM with respect to the  Plasmodium Falciparum  strain K1.

       In Vivo Antimalarial Efficacy Studies 
       [0877]    In vivo antimalarial activity is assessed for groups of three female NMRI mice (20-22 g) intravenously infected on day 0 with  P. berghei  strain GFP-ANKA (0.2 mL heparinized saline suspension containing 2×10 7  parasitized erythrocytes). In control mice, parasitaemia typically rise to approximately 40% by day 3 after infection, and control mice die between day 5 and day 7 after infection. For the mice treated with compounds, the compounds are either formulated in an aqueous-gelatine vehicle with 3 mg/mL compounds or in tween 80/ethanol (7%/3%) with 5 mg/mL. 
         [0878]    Compounds are administered intraperitonealy or subcutaneously either as two consecutive twice-daily dosing (BID) (2×75 mg/kg BID, 24 and 48 hours after infection) or as four consecutive daily doses (4×10 mg/kg or 4×50 mg/kg, 3, 24, 48 and 72 hours after infection). With the double BID-dose regimen, 24 h after the last drug treatment, 1 μl tail blood is taken, resuspended in 1 mL PBS buffer and parasitemia determined with a FACScan (Becton Dickinson) by counting 100 000 red blood cells. Tail blood samples for the quadruple-dose regimen are processed on day 4 after infection. Activity is calculated as the difference between the mean value of the control and treated groups expressed as a percent relative to the control group. For parasetimias lower than 0.1%, the presence of parasites in the FACS gate is checked visually. The survival days of infected mice treated with compound is also recorded for each compound. Mice surviving for 30 days are checked for parasitemia and subsequently euthanized. A compound is considered curative if the animal survives to day 30 post-infection with no detectable parasites.
