Definitions
- the present invention relates to the field of cyano-(substituted) methylenepiperidinophenyl oxazolidinones having antibacterial activity against Gram-positive and Gram-negative bacteria. While not being bound to any theory, it is thought that the antibacterial activity is based on the their ability to inhibit bacterial ribonucleoprotein through differential binding at single/multiple ribonucleoprotein sites.
- the invention also relates to processes for making the compounds, to pharmaceutical compositions containing the compounds and to methods of using the compounds including treating bacterial infections with the compounds.
- Oxazolidinones represent a novel chemical class of synthetic antimicrobial agents. Following a chequered historical development since about the early-1980s, a watershed event took place with the clinical ' development and release for medical use in the late 2000s of the first representative, Linezolid, of this class 1 ' 2
- This advance enabled the profiling of the unique properties of the members of this class, which is that they display activity against important Gram-positive human and veterinary pathogens including methicillin-resistant Staphylococcus aureus (MRSA), vancomycin resistant enterococci (VRE) and ⁇ -lactam resistant Streptococcus pneumoniae (PRSP).
- MRSA methicillin-resistant Staphylococcus aureus
- VRE vancomycin resistant enterococci
- PRSP ⁇ -lactam resistant Streptococcus pneumoniae
- the oxazolidinones also show activity against Gram-negative aerobic bacteria and Gram- positive and Gram-negative anaerobes .
- oxazolidinones have also surfaced. They are inactive against Enterobacteriaceae 4 . They are generally bacteriostatic and do not display activity at a useful level against aerobic fastidious Gram-negative pathogens, as well as Gram-negative anaerobes. Moreover their potency for atypical respiratory pathogens such as Mycoplasma pneumoniae, M. hominis, Ureaplasma Urealyticium and Chlamydia species is of a borderline range which could result into unacceptable clinical efficacy for the treatment of respiratory tract infections 3 .
- Linezolid is shown to have two targets in cells for its inhibitory effects. It binds to the 50S subunit within domain V of the 23S or RNA peptidyl fransferase center near the interface with the 30S subunit, thereby blocking the formation of the tMet-tRNA-ribosome-mRNA ternary complex. In addition, linezolid associates with the nascent 50S particle and stops the assembly process 7 .
- oxazolidinones are bacteriostatic, as indeed are most other agents that inhibit bacterial protein synthesis, there is a strong likelihood that resistance can emerge under selective pressure during therapy, specially for infections which require a bactericidal therapy to be used.
- the significant concern related to this class of antibacterials is attributed to this essentially bacteriostatic effect against their prime target pathogens such as staphylococci, enterococci and pneumococci. It is pertinent to quote from the Adis R&D insight report (Document 013296 dated December 27, 2001) that an oxazolidinone AZD 2563 under clinical development is described to be "ineffective against linezolid-resistant S. pneumoniae".
- the present invention describes a novel series of oxazolidinones which display increased potency, and incorporate bactericidal activity, in contrast to the earlier-described bacteriostatic activity, against Linezolid-sensitive/-resistant strains, thus indicating a differential binding at the conventional site/s of the ribonucleoprotein and/or targeting multiple such receptor sites.
- a study of literature-described oxazolidinones and the novel compounds of the present invention has enabled the identification of newer / additional structural motifs of the oxazolidinone class, novel and non-obvious from the prior art, which support the activity against the Linezolid-sensitive/-resistant pathogens.
- oxazolidinones displaying such bactericidal activity or useful activity against Linezolid-sensitive/-resistant or other oxazolidinone-resistant microbial pathogens.
