Definitions

  • This invention relates to a method of presenting pharma ⁇ ceutically active peptides, particularly receptor bloc ers and i munogenic peptides, in cyclodextrin compositions.
  • Cyclodextrins are cyclic molecules containing six or more ⁇ -D-glucopyranose units linked together at the 1,4 positions.
  • the 2-hydoxypropyl- ⁇ -cyclodextrin (HPCD) has been used for stabilization and solubilization of various compounds,
  • 35 does not disclose the solubilization of peptides in cyclodex ⁇ trin.
  • TP-5 is effective in blocking the stimulation of smooth muscle contraction caused by the neurotoxin (+)-anatoxin-a (ANTX) .
  • ANTX is a bicyclic a ine exotoxin produced by the blue-green algae, Anabaena flos-a ⁇ uae, and has been found to cause death to livestock and waterfowl.
  • the toxin acts by depolarizing blockade of neuromuscular transmission. Such depolarization results in respiratory paralysis.
  • the action of ANTX has been ascribed to its potent nicotinic cholinergic agonist activities in skeletal muscle and mammalian skeletal muscle and the central nervous system.
  • ANTX can also cause cardiovascular aberrations by activation of nicotinic receptors in the adrenal medulla and sympathetic ganglia.
  • the antagonist effect of TP-5 has been attributed to its ability to block nicotinic receptors in a noncompetitive manner.
  • compositions containing cyclodextrin complexes of peptides particularly synthetic peptides and peptides of £ 40 amino acids.
  • Such peptides are particularly useful for administration as receptor agonists, receptor antagonists, and as vaccines.
  • the compositions of the invention provide improved means for delivery of such peptides.
  • peptides especially peptides of about three to 20 amino acids, are unstable in low concentrations and tend to loose biological activity. While Brewster describes the value of preparing formulations of cyclodextrin and regulatory proteins to avoid conformational changes, there is no sugges ⁇ tion therein that cyclodextrin would be useful for increasing stability of small peptides such as thymopentin.
  • the instant invention improves methods of administration of peptides to the ucosa of mammals in need of treatment with effective peptides.
  • the invention provides a means of formulating peptides to avoid loss of efficacy and to facilitate delivery of the active peptides to the reactive site.
  • the method has been exemplified using the synthetic peptides corresponding position 32-36 of thymopoietin and known as TP-5 (Arg-Lys-Asp-Val-Tyr) . While the hydroxypropyl cyclodextrin has been exemplified, other cyclodextrins, including mixed cyclodextrins, may be used in the method of the invention.
  • TP-5 (10" 2 M) was synthesized as describe in Chiang, et al, Life Sci 49; (1991) PL13-19 and was made up in various percentages of HPCD dissolved in sterile water. Mixtures were stirred for about one hour. The solutions were then maintained at room tempera- ture. Control solutions of TP-5 dissolved in sterile water without HPCD were also prepared in the same manner. The two sets of solutions were stored at ambient room temperatures (25°C) for 14 months. Aliquots were removed monthly for stability testing.
  • TP-5 The stability study was performed by assaying the ability of the TP-5 solutions to counteract the stimulation of contraction of guinea pig ileum by ANTX. Guinea pig ileum contraction stimulated by ANTX was performed as reported in Chiang, et al. (supra) . The final concentration of TP-5 for use was obtained by diluting with Krebs-Ringer buffer.
  • EXAMPLE I Aqueous solution of 2-hydroxy- ⁇ -cyclodextrin (HPCD) were prepared at concentration of 2.5%, 5.0%, 10%, 15%, 20%, 25% and 30% (w/v) . TP-5 was added in sufficient amounts to provide a final molarity of 10 "2 molar solution of TP-5.
  • IC 50 values of the inhibition by TP-5 of guinea-pig ileum contraction stimulation by ANTX at 3 x 10 "5 N was compared using freshly made 10_ 2 molar solutions of TP-5 and similar concentrations of TP-5 in 5%, 15% and 20% solutions of HPCD which had been stored for 14 months at ambient temperature to determine relative activity. The results are shown as mean + s.e. of four separate experiments as indicated in Table I TABLE I
  • a composition containing 0.5 mg TP-5 is administered intraperitoneally to rabbits to provide protection against ANTX.
  • Formulations may be administered for up to 4 days. Dosage range for thymopentin may vary from 1 ⁇ g/kg/day to 1 g/kg/day. It is, of course, understood that smaller animals will require higher dosage per kilogram than larger mammals.
  • Formulations of active agents in HPCD for administration may be prepared using any pharmaceutically appropriate solvent, including water, isotonic saline, glucose, or saline.
  • the formulations may be administered orally in the form of liquid bolus, or may be administered as lyophilized powders or tablets. When provided as lyophilized powders, many of the compositions may be administered nasally for inhalation.
  • Compositions of the invention may be administered parenterally by, for example intramuscular, subcutaneous or intraperitoneal routes. Solutions of the cyclodextrin inclusion complexes can be administered to the mucosa by any means appropriate such as by nasal spray, buccal tablet or sublingually as drops.
  • the site of administration will be governed, in many instances, by the site of effective response. For example, it is often advantageous to administer immunogenic peptides to the mucosa.
  • peptides could be formulated in a similar manner.
  • Such peptides include splenopentin (SP-5) having the structure Arg-Lys-Glu-Val-Tyr. This peptide is effective for inducing T-cell differentiation and for modulation of neuromus- cular transmission.
  • SP-5 splenopentin
  • DSIP delta sleep inducing peptide
  • vasoactive intestinal peptide VIP
  • biotinyl-VIP from human, porcin, chick, rat or other sources, having the sequence His-Ser-Asp-Ala-Val-Phe-Thr-Asp-Asn-Tyr-Thr-Arg-Leu- Arg-Lys-Gln-Met-Ala-Val-Lys-Tyr-Leu-Asn-Ser-Ile-Leu-Asn-NH j for prevention for cell killing by human immunodeficiency virus (Nature 335; 639-642 (1984)) and for pharmacological treatment of tissues involving neuromuscular transmission (Arch, int.
  • the peptide HG165-178 representing the sequence 165.-178 of gpl20 is represented by the sequence Asn-Ile-Ser-Thr-Ser-Ile-Arg-Gly-Lys-Val-Gln-Lys- Gln-Lys-Glu-Tyr, which is analogous to sequences in snake neurotoxins and rabies virus glycoprotein is conjugated to a keyhole limpet hemocyanin (KLH) and can be, thereafter, encapsulated in cyclodextrin to prevent the binding of viruses, toxins, viral coatings and gpl20 to cells. (See FEBS Letters 311; 115-118 (1992)).
  • KLH keyhole limpet hemocyanin
  • the methods of the invention should be particularly considered to stabilize peptides containing asparytyl, asparaginyl and glycine residues.
