Description:
Antimicrobial Agents This invention relates to the use of a class of tertiary amino compounds as antimicrobial agents, particularly as antibacterial or antifungal agents and to novel members of that class per se, and to pharmaceutical compositions comprising such compounds.

Background to the Invention Many classes of antibacterial agents are known, including the penicillins and cephalosporins, tetracyclines, sulfonamides, monobactams, fluoroquinolones and quinolones, aminoglycosides, glycopeptides, macrolides, polymyxins, lincosamides, trimethoprim and chloramphenicol. The fundamental mechanisms of action of these antibacterial classes vary.

Bacterial resistance to many known antibacterials is a growing problem.

Accordingly there is a continuing need in the art for alternative antibacterial agents, especially those that have mechanisms of action fundamentally different from the known classes.

Amongst the Gram-positive pathogens, such as Staphylococci, Streptococci, Mycobacteria and Enterococci, resistant strains have evolved/arisen which makes them particularly difficult to eradicate. Examples of such strains are methicillin resistant Staphylococcus aureus (MRSA), methicillin resistant coagulase negative Staphylococci (MRCNS), penicillin resistant Streptococcus pneumoniae and multiply resistant Enterococcus faecium.

Recently there has been an emergence of vancomycin-resistant strains of enterococci (Woodford N. , 1998. Glycopeptide-resistant enterococci: a decade of experience. Journal of Medical Microbiology. 47: 849-62). Vancomycin-resistant enterococci are particularly hazardous in that they are frequent causes of hospital based infections and are inherently resistant to most antibiotics. Vancomycin

works by binding to the terminal D-Ala-D-Ala residues of the cell wall peptidoglycan precursor. The high-level resistance to vancomycin is known as VanA and is conferred by a genes located on a transposable element which alter the terminal residues to D-Ala-D-lac thus reducing the affinity for vancomycin.

In view of the rapid emergence of multidrug-resistant bacteria, the development of antibacterial agents with novel modes of action that are effective against the growing number of resistant bacteria, particularly the vancomycin resistant enterococci and beta-lactam antibiotic-resistant bacteria, such as methicillin- resistant Staphylococcus aureus, is of utmost importance.

Many classes of antifungal agents are known, including amphotericin B, azoles and triazoles. The fundamental mechanisms of action of these antifungal classes may vary but fungal resistance to these compounds is a growing problem.

There is an increased awareness of the morbidity and mortality associated with infections by resistant fungal pathogens such as Candida e. g. C. albicans, C. parapsilosis, C. krusei, C. glabrata and C. tropicalis ; and Aspergillus e. g. A. fumigatus, A. terreus and A. niger, Cryptococcus e. g. C. neoformans ; Scedosporium e. g. S. prolificans, and Fusarium species (Canuto et. al. 2002.

Antifungal drug resistance to azoles and polyenes. Lancet Infection and Disease 2; 550-563). Accordingly, there is a continuing need in the art for alternative antifungal agents, especially those that have mechanisms of action fundamentally different from the known classes.

Brief Description of the Invention This invention is based on the finding that certain tertiary amines have antimicrobial activity and makes available a new group of antimicrobial agents. It has been found that the compounds with which this invention is concerned are antibacterial with respect to a range of bacteria, of both the Gram-positive and Gram-negative types. Many of the compounds of the invention show activity against bacteria responsible for infections of the gastro-intestinal tract, such as

Enterococci, and/or against those responsible for respiratory infections, such as Streptococcus pneumoniae and/or Haemophilus influenzae, and/or those usually described as hospital acquired infections, such as Staphylococcus aureus and/or against yeasts responsible for fungal infections.

While the mechanism of action of the compounds with which the invention is concerned may be of some interest, it is their overall antimicrobial effect which makes them useful, and the invention is therefore not limited by any theory of their action.

Assay Methods The following bacterial and yeast strains were used: Bacillus subtilis 168CA, Candida albicans ATCC 90028, Enterococcus faecalis ATCC 29212, Escherichia coli ATCC 25922, Haemophilus influenzae ATCC 49247, Pseudomonas aeruginosa 101021, Saccharomyces cerevisiae MYA-658, Staphylococcus aureus MS 601055 and Streptococcus pneumoniae ATCC 49619.

M ! Cs were determined by the broth microdilution method (National Committee for Clinical Laboratory Standards. 2000. Methods for dilution antimicrobial susceptibility tests for bacteria that grow aerobically ; approved standard-5th ed. ). Microtitre plates containing the test compounds (standard concentration range : 0. 125-64 tg/mi) were inoculated with a starting inoculum of 5x105 cfu/ml.

Mueller-Hinton broth (Oxoid) was used for all non-fastidious organisms. S. pneumoniae and H. influenzae were grown in brain heart infusion (Sigma) supplemented with 5% horse serum and 2 mg of NAD per litre (H. influenzae).

The MIC was defined as the lowest concentration of compound inhibiting visible growth.

For S. cerevisiae and C. albicans, Sabouraud dextrose broth (Sigma) was used.

Microtitre plates containing the test compounds were inoculated with 1: 100 dilutions of cultures at an absorbance at 600 nm (A600) of 0. 09. S. cerevisiae and C. albicans were incubated at 30°C for 44-48 h and at 37°C for 28 h, respectively. The MIC was defined as the lowest concentration of compound inhibiting visible growth. The IC50 was defined as a reduction in A600 of #50% compared to A600 of a culture grown in the absence of compound.

Activities were scored as'A'if the MIC was single digit eg. <8 microgrammes/ml, 'B'if the MIC was 16 to 64 microgrammes/ml and'C'if the MIC was greater than 64 microgammes/ml. The data set in the above table is data collected from B. subtilis, E. coli and S. cerevisiae tests. IC50 values were used to evaluate effects of compounds on the growth of yeast.
