Definitions
- This invention relates to the use of hydroxamic acid derivatives as antibacterial agents.
- bacterial pathogens are classified as either Gram-positive or Gram- negative. Many antibacterial agents (including antibiotics) are specific against one or other Gram-class of pathogens. Antibacterial agents effective against both Gram- positive and Gram-negative pathogens are therefore generally regarded as having broad spectrum activity.
- antibacterial agents including the penicillins and cephalosporins, tetracyclines, sulfonamides, monobactams, fluoroquinolones and quinolones, aminoglycosides, glycopeptides, macrolides, polymyxins, lincosamides, trimethoprim and chloramphenicol.
- penicillins and cephalosporins including the penicillins and cephalosporins, tetracyclines, sulfonamides, monobactams, fluoroquinolones and quinolones, aminoglycosides, glycopeptides, macrolides, polymyxins, lincosamides, trimethoprim and chloramphenicol.
- penicillins and cephalosporins tetracyclines
- sulfonamides monobactams
- fluoroquinolones and quinolones aminoglycosides
- glycopeptides
- MRSA methicillin resistant Staphylococcus a ⁇ reus
- MRCNS methicillin resistant coagulase negative Staphylococci
- Streptococcus pneumoniae and multiply resistant Enterococcus faecium.
- Pathogenic bacteria are often resistant to the aminoglycoside, ⁇ -lactam (penicillins and cephalosporins), and chloramphenicol types of antibiotic. This resistance involves the enzymatic inactivation of the antibiotic by hydrolysis or by formation of inactive derivatives.
- the ⁇ -lactam (penicillin and cephalosporin) family of antibiotics are characterised by the presence of a ⁇ -lactam ring structure. Resistance to this family of antibiotics in clinical isolates is most commonly due to the production of a "penicillinase" ( ⁇ -lactamase) enzyme by the resistant bacterium which hydrolyses the ⁇ -lactam ring thus eliminating its antibacterial activity.
- 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 peptidioglycan 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.
- the natural antibiotic actinonin (see for example J.C.S Perkin I, 1975, 819) is a hydroxamic acid derivative of Structure (A):
- the matlystatin group of compounds share a number of structural similarities with actinonin. Both are peptidic molecules with functional hydroxamic acid metal binding groups (Ogita et al., J. Antibiotics. 45(11 ):1723-1732; Tanzawa et al., J. Antibiotics. 45(11 ): 1733-1737; Haruyama et al., J. Antibiotics. 47(12): 1473-1480; Tamaki et al., J. Antibiotics. 47(12):1481-1492).
- hydroxamic acid derivatives have previously been disclosed as inhibitors of matrix metalloproteinases (MMP), enkephalinase, angiotensin and other natural enzymes which play various roles in several human disease states.
- MMP matrix metalloproteinases
- enkephalinase enkephalinase
- angiotensin and other natural enzymes which play various roles in several human disease states.
- WO 98/11063 and WO 99/46241 disclose the use of certain ester and thioester compounds containing a hydroxamic acid group as inhibitors of the proliferation of rapidly dividing tumour cells, and claim that use together with a class of such esters and thioesters perse.
- This invention is based on the finding that a subset of the ester and thioester compounds containing a hydroxamic acid group with which WO 98/11063 and WO 99/46241 are concerned have antibacterial activity, against members of the Gram-positive and/or Gram-negative classes.
- the isolation and characterisation of PDF has been facilitated by an understanding of the importance of the metal ion in the active site (Groche et al., Biophys. Biochem. Res. Commun., 246:324-6, 1998).
- the Fe 2+ form is highly active in vivo but is unstable when isolated due to oxidative degradation (Rajagopalan et al., J. Biol. Chem. 273:22305-10, 1998).
- the Ni 2+ form of the enzyme has specific activity comparable with the ferrous enzyme but is oxygen-insensitive (Ragusa et al., J. Mol. Biol. 1998, 280:515-23, 1998).
- the Zn 2+ enzyme is also stable but is almost devoid of catalytic activity (Rajagopalan et al., J. Am. Chem. Soc. 119:12418-12419, 1997).
