Definitions
- the present invention relates to short peptides. More particularly, it relates to short peptides capable of selectively binding to receptors on cells.
- the identification of multiple receptors is particularly interesting in that many opioids exert a variety of effects including analgesia, addiction, respiratory depression, inhibition of gut transit, and cardiotoxicity. See e.g. , The Pharmacological Basis of Therapeutics, McMillan, pp. 496-536, New York (1980); Hruby et al., Med . Res . Rev. .9:343 (1989); and Zimmermann, et al., J. Med . Chem . 22:895 (1990). Recent work has suggested that opioid peptides may also be involved in pathological states, including cancer. As shown in Table 1, multiple opioid receptors are present on numerous tumor cell lines.
- opioids While the exact role played by opioid peptides in oncogenic events remains unknown, opioids have been found to alter cell function and growth [Slotkin et al. Life Sci . J2 :861 (1980); and Wilson et al. J. Pharmacol . Exp. Ther. 199:368 (1976)], to inhibit the growth of cultured neuroblastoma cells [Zagon et al. Brain Res . Bull . 2 ⁇ 25 (1981)], and to inhibit neuroblastoma tumor growth and prolong survival times, in an opioid antagonist sensitive manner, in mice with transplanted neuroblasto as, B-16 melanoma, MCF-7 breast cancer, human lung cancer cells and others [Zagon et al. Life Sci.
