  • Patent number: 5413797
    Abstract: ACTH polymeric controlled release systems are described wherein the ACTH retains good biological activity and is released over an extended period of time following administration by injection. In the preferred embodiment, the ACTH polymeric microspheres are made using very cold temperatures to freeze the polymer-ACTH mixtures into polymeric microspheres with very high retention of biological activity and material. Sustained release of biologically active ACTH is achieved when the microspheres are tested in vitro, extending over a period of greater than one day to several months. Altered release can be achieved by inclusion of degradation modifiers, pore forming agents, and stabilizers of the ACTH.

  • Patent number: 5209920
    Abstract: Inbred Lewis (LEW/N) female rats develop an arthritis in response to Group A streptococcal cell wall peptidoglycanpolysaccharide (SCW) which mimics human rheumatoid arthritis. Histocompatible Fischer (F344/N) rats, on the other hand, do not develop arthritis in response to the same SCW stimulus. To evaluate this difference in inflammatory reactivity between the two strains, the function of the hypothalamic-pituitary-adrenal axis and its ability to modulate the development of the inflammatory response was studied. It has been found that, in contrast to F344/N rats, LEW/N rats had markedly impaired plasma ACTH and corticosterone responses to SCW, recombinant human Interleukin-1 alpha (IL-1 alpha), the serotonin agonist, quipazine, and synthetic rat corticotropin-releasing hormone (CRH). In addition, LEW/N rats compared to F344/N rats had smaller adrenal glands and larger thymuses. Treatment of LEW/N rats with replacement doses of dexamethasone decreased the severity of their SCW-induced arthritis.

  • Patent number: 5132111
    Abstract: Agonists and antagonists of rCRF are disclosed that exhibit good binding affinity to CRF receptors. One exemplary agonist is: H-Ser-Gln-Glu-Pro-Pro-Ile-Ser- Leu-Asp-Leu-Thr-Phe-His-Leu-Leu-Arg-Glu-Met-Leu-Glu-Met- Ala-Arg-Ala-Glu-Gln-Glu-Ala-Glu-Gln-Ala-Ala-Leu-Asn-Arg- Leu-Leu-Leu-Glu-Glu-Ala-NH.sub.2. In the agonists, one or more of the first five N-terminal residues may be deleted or may be substituted by a peptide up to 10 amino acids long. A number of other substitutions may also be made throughout the chain. Similar peptides which function as CRF antagonists are created by deleting the first 7, 8 or 9 N-terminal residues. These analogs are coupled to a cytotoxin, such as gelonin, by a dialdehyde or the like, e.g., glutaraldehyde. The conjugates may be used to eliminate CRF Target Cells, and thus to regulate secretion of ACTH, .beta.-lipotropin and the like.

  • Patent number: 5043321
    Abstract: A method for alleviating stress induced immunosuppression is accomplished by application of low doses of ANF[1-28] or other ANF analogs having intact N-terminal sequences. Atrial natriuretic factors (ANFs) with intact N-terminal sequences are shown to be effective inhibitors of CRF 41-stimulated ACTH secretion when the ANFs are present in low concentrations. ANF[1-28] significantly inhibited ACTH release stimulated by 1-5 nM CRF. At the most effective concentration of 100 pM, ACTH release was inhibited by 40.1% (p<0.001). This effect was manifested after three hours, but not after only one half or one hour of incubation. Conversely, ANF[5-28], at concentrations of 10 to 10,000 pM, had no effect on ACTH secretion after one half, one, or three hours. ANF[1-11] weakly inhibited ACTH secretion at concentrations of 100 pM and 1000 pM. Again, three hours of incubation was required to manifest these effects.
