  • Patent number: 8420852
    Abstract: Phospholipase A2 (PLA2) forms are expressed in spinal cord whose inhibition induces a potent antihyperalgesia. PLA2 inhibitor compounds are provided that include a common motif consisting of a 2-oxoamide with a hydrocarbon tail and a four carbon tether. The compounds block Group IVA calcium dependent PLA2 (cPLA2) and/or Group VIA calcium independent PLA2 (iPLA2) and/or Group V secreted PLA2 (sPLA2). Pharmaceutical compositions of compounds having cPLA2 inhibitory activity (but not iPLA2 or sPLA2 inhibitory activity) are useful in treating multiple sclerosis, while compositions of compounds having sPLA2 inhibitory activity (as well as iPLA2 and CPLA2 activity) are useful in treating spinal cord injuries (with related functional recovery).

  • Publication number: 20100048727
    Abstract: Novel perfluoroketone compounds of formula [I] and [Ia] are described. Also described are uses thereof, such as for inhibition of phospholipase A2 activity. Therapeutic uses thereof are also described, such as for the treatment of neural conditions and/or inflammatory conditions, such as demyelinating (e.g., multiple sclerosis) and neural injury (e.g., spinal cord injury).

  • Publication number: 20060058225
    Abstract: The present invention provides methods of preventing and treating neural inflammatory or demyelinating disease, such as multiple sclerosis, via an inhibition of the activity or expression of phospholipase A2. The invention further relates to methods of identifying phospholipase A2 inhibitors and their use thereof for the prevention and/or treatment of neural inflammatory or demyelinating disease. An observed increase in the amount of phospholipase A2 in neural lesions in the EAE animal model system indicates that elevated phospholipase A2 activity or levels correlate with neural inflammatory or demyelinating disease. Therefore, in a further aspect the invention provides methods for the diagnosis and prognostication of neural inflammatory or demyelinating disease, such as multiple sclerosis.
