Definitions

  • the present invention relates to the use of novel N-[2-(N-formyl-N-hydroxy- amino)-ethyl]-arylamide compounds, and pharmaceutical compositions containing these compounds as peptide deformylase inhibitors.
  • Bacterial initiator methionyl tRNA is modified by methionyl tRNA formyltransferase (FMT) to produce formyl-methionyl tRNA.
  • FMT methionyl tRNA formyltransferase
  • f-Met formyl methionine
  • PDF or Def Polypeptide deformylase
  • PDF and MAP are both essential for bacterial growth, and PDF is required for MAP activity. This series of reactions is referred to as the methionine cycle (Figure 1)
  • FIG. 1 The methionine cycle.
  • polypeptide deformylase homologous genes have been found in bacteria, in chloroplast-containing plants, in mice and in human.
  • the plant proteins are nuclear encoded but appear to carry a chloroplast localization signal. This is consistent with the observation that chloroplast RNA and protein synthesis processes are highly similar to those of eubacteria. No information on protein expression of mammalian PDF gene homologs or functional role for such proteins has been demonstrated to date (Meinnel T. 2000, Parasitology Today, 16(4), 165-168).
  • Polypeptide deformylase is found in all eubacteria for which high coverage genomic sequence information is available. Sequence diversity among PDF homologs is high, with as little as 20% identity between distantly related sequences. However, conservation around the active site is very high, with several completely conserved residues, including one cysteine and two histidines which are required to coordinate the active site metal (Meinnel, T. et al, 1997, Journal of Molecular Biology, 267, 749-761). PDF is recognized to be an attractive anti-bacterial target, as this enzyme has been demonstrated to be essential for bacterial growth in vitro (Mazel, D. et al, EMBO J.
  • the present invention involves novel N-[2-(N-formyl-N-hydroxy- amino)-ethyl]-arylamides with bacterial polypeptide deformylase inhibiting activity represented by Formula (I) hereinbelow and their use as PDF inhibitors.
  • the present invention further provides methods for inhibiting PDF in an animal, including humans, which comprises administering to a subject in need of treatment an effective amount of a compound of Formula (I) as indicated hereinbelow.
  • A is a fused aromatic or aliphatic ring system consisting of five to seven atoms and incorporating zero to four heteroatoms, such that A may be optionally substituted with one, two, or three substituents selected from the group consisting of: optionally substituted alkyl or cycloalkyl of one to nine carbons, halo, alkoxy of one to nine carbons, hydroxy, amino, hydroxyalkyl of one to nine carbons, alkoxyalkyl, optionally substituted aryl or optionally substituted heteroaryl, carboxy, and alkoxycarbonyl, and X and Y are, independently, halo, hydroxy, or hydroxyalkyl of one to three carbons.
  • alkyl refers to an optionally substituted hydrocarbon group joined together by carbon-carbon bonds.
  • the alkyl hydrocarbon group may be linear, branched or cyclic, saturated or unsaturated.
  • aryl refers to an optionally substituted aromatic group with at least one ring having a conjugated pi-electron system, containing up to two conjugated or fused ring systems.
  • Aryl includes carbocyclic aryl, heterocyclic aryl and biaryl groups, all of which may be optionally substituted.
  • Preferred compounds of the present invention include:
  • compositions of the present invention are pharmaceutically acceptable salts and complexes.
  • Preferred are the hydrochloride, hydrobromide and trifluoroacetate salts.
  • the compounds of the present invention may contain one or more asymmetric carbon atoms and may exist in racemic and optically active forms. All of these compounds and diastereomers are contemplated to be within the scope of the present invention.
  • the compounds and processes of the present invention will be better understood in connection with the following synthetic schemes, which are merely illustrative of the methods by which the compounds of the invention may be prepared and are not intended to limit the scope of the invention as defined in the appended claims.
  • Aryl carboxylic acids (l) may be purchased or prepared by standard literature procedures. Conversion of (1) to the acid chloride and amination with the dimethyl acetal of aminoacetaldehyde provides the amide (2). Deprotection with 6NHC1 in THF and treatment of the resulting aldehyde (3) with hydroxylamine and sodium acetate in MeOH provides the oxime (4). Reduction of the oxime to the hydroxylamine (5) is accomplished with NaCNBH3 in MeOH under acidic conditions. Finally, N-formyl-N-hydroxylamine (I) is obtained by treatment of the hydroxylamine in pyridine with the mixed anhydride formed from formic acid and acetic anhydride.
  • the present compounds are useful for the treatment of bacterial infections including but not limited to respiratory tract infections and/or Gram positive infections.
  • Compounds of Formula (I) and their pharmaceutically acceptable salts may be administered in a standard manner for antibiotics, for example orally, parenterally, sub-lingually, dermally, transdermally, rectally, via inhalation or via buccal administration.
  • Compositions of Formula (I) and their pharmaceutically acceptable salts which are active when given orally can be formulated as syrups, tablets, capsules, creams and lozenges.
  • a syrup formulation will generally consist of a suspension or solution of the compound or salt in a liquid carrier for example, ethanol, peanut oil, olive oil, glycerine or water with a flavoring or coloring agent. Where the composition is in the form of a tablet, any pharmaceutical carrier routinely used for preparing solid formulations may be used.
  • any routine encapsulation is suitable, for example using the aforementioned carriers in a hard gelatin capsule shell.
  • any pharmaceutical carrier routinely used for preparing dispersions or suspensions may be considered, for example aqueous gums, celluloses, silicates or oils, and are incorporated in a soft gelatin capsule shell.
  • Typical parenteral compositions consist of a solution or suspension of a compound or salt in a sterile aqueous or non-aqueous carrier optionally containing a parenterally acceptable oil, for example polyethylene glycol, polyvinylpyrrolidone, lecithin, arachis oil or sesame oil.
  • a parenterally acceptable oil for example polyethylene glycol, polyvinylpyrrolidone, lecithin, arachis oil or sesame oil.
  • compositions for inhalation are in the form of a solution, suspension or emulsion that may be administered as a dry powder or in the form of an aerosol using a conventional propellant such as dichlorodifluoromethane or trichlorofluoromethane.
  • a typical suppository formulation comprises a compound of Formula (I) or a pharmaceutically acceptable salt thereof which is active when administered in this way, with a binding and/or lubricating agent, for example polymeric glycols, gelatins, cocoa-butter or other low melting vegetable waxes or fats or their synthetic analogs.
  • a binding and/or lubricating agent for example polymeric glycols, gelatins, cocoa-butter or other low melting vegetable waxes or fats or their synthetic analogs.
  • Typical dermal and transdermal formulations comprise a conventional aqueous or non-aqueous vehicle, for example a cream, ointment, lotion or paste or are in the form of a medicated plaster, patch or membrane.
  • the composition is in unit dosage form, for example a tablet, capsule or metered aerosol dose, so that the patient may administer a single dose.
  • Each dosage unit for oral administration contains suitably from 0.1 mg to 500 mg/Kg, and preferably from 1 mg to 100 mg/Kg, and each dosage unit for parenteral administration contains suitably from 0.1 mg to 100 mg/Kg, of a compound of Formula(I) or a pharmaceutically acceptable salt thereof calculated as the free acid.
  • Each dosage unit for intranasal administration contains suitably 1-400 mg and preferably 10 to 200 mg per person.
  • a topical formulation contains suitably 0.01 to 5.0% of a compound of Formula (I).
  • the daily dosage regimen for oral administration is suitably about 0.01 mg/Kg to 40 mg/Kg, of a compound of Formula(I) or a pharmaceutically acceptable salt thereof calculated as the free acid.
  • the daily dosage regimen for parenteral administration is suitably about 0.001 mg/Kg to 40 mg/Kg, of a compound of Formula (I) or a pharmaceutically acceptable salt thereof calculated as the free acid, the daily dosage regimen for intranasal administration and oral inhalation is suitably about 10 to about 500 mg/person.
  • the active ingredient may be administered from 1 to 6 times a day, sufficient to exhibit the desired activity.
  • S. aureus or E. coli PDF activity is measured at 25°C, using a continuous enzyme- linked assay developed by Lazennec & Meinnel, (1997) "Formate dehydrogenase- coupled spectrophotometric assay of peptide deformylase” Anal. Biochem. 244, pp.180- 182, with minor modifications.
  • the reaction mixture is contained in 50 uL with 50 mM potassium phosphate buffer (pH7.6), 15 mM NAD, 0.25 U formate dehydrogenase.
  • the substrate peptide, f-Met-Ala-Ser is included at the Kjyj concentration.
  • the reaction is triggered with the addition of 10 nM Def 1 enzyme, and absorbance is monitored for 20 min at 340 nm.
  • This panel consisted of the following laboratory strains: Staphylococcus aureus Oxford, Staphylococcus aureus WCUH29, Enterococcus faecalis I, Enterococcus faecalis 1, Haemophilus influenzae Ql, Haemophilus influenzae NEMO, Moraxella catarrhalis 1502,
