  • Patent number: 6849602
    Abstract: The invention provides a method of alleviating neuropathic pain in a subject by administering a neuropathic pain alleviating amount of prosaposin receptor agonist to the subject. The invention also provides a method of inhibiting the onset of neuropathic pain in a subject by administering neuropathic pain alleviating amount of prosaposin receptor agonist to the subject. The present invention also provides prosaposin receptor agonists and the use of these agonists for stimulating neurite outgrowth, inhibiting neural cell death, promoting myelination and inhibiting neural demyelination.

  • Patent number: 6458357
    Abstract: Retro-inverso peptide analogs derived from the active neurotrophic region of saposin C. The saposin C-derived peptides (prosaptides) induce neurite outgrowth in vitro, prevent programmed cell death, induce myelination and have an analgesic effect. They are useful in the treatment of central and peripheral nervous system disorders and pain management. The retro-inverso peptides are significantly more resistant to metabolic degradation than the corresponding non-inverted peptides.

    Abstract: Retro-inverso peptide analogs derived from the active neurotrophic region of saposin C which include the amino acid sequence LLEENNDL (all D-amino acids) (SEQ ID NO: 4). These peptides induce neurite outgrowth in vitro, prevent programmed cell death, induce myelination and have an analgesic effect. They are useful in the treatment of central and peripheral nervous system disorders and neuropathic pain.

  • Patent number: 5700909
    Abstract: Prosaposin and peptide derivatives derived therefrom will promote neurite outgrowth in vitro. A peptide consensus sequence was determined by comparing the active neurite outgrowth-inducing saposin C peptide sequence with that of various hematopoietic and neuropoietic cytokines. These cytokine-derived peptides will promote the same processes as their corresponding cytokines. In addition, prosaposin and saposin C promote increased nerve cell myelination ex vivo.
