Abstract:
Bioerodible poly(ortho esters) useful as orthopedic implants or vehicles for the sustained delivery of pharmaceutical, cosmetic and agricultural agents from dioxane-based di(ketene acetals). Block copolymers contain these bioerodible poly(ortho esters). These block copolymers have both hydrophilic and hydrophobic blocks. They form micelles in aqueous solution, making them suitable for encapsulation or solubilization of hydrophobic or water-insoluble materials; and they also form bioerodible matrices for the sustained release of active agents.
Abstract:
Improved CRF antagonist peptides have the formula: ##STR1## wherein R.sub.30 is Cys or Glu; R.sub.33 is Cys, Lys or Orn; provided that when R.sub.30 is Cys, R.sub.33 is Cys and when R.sub.30 is Glu, R.sub.33 is Lys or Orn. The N-terminus may be extended by Asp-Leu-Thr. Lys may be substituted for Arg.sup.23 and its side chain connected by a lactam bridge to Glu.sup.20 to form a dicyclic peptide. Specific CRF antagonists disclosed include (cyclo 30-33) [D-Phe.sup.12, Nle.sup.21,38, Glu.sup.30, Lys.sup.33 ]rCRF(12-41); (cyclo 30-33) [D-Phe.sup.12, Nle.sup.21,38, Glu.sup.30, Orn.sup.33 ]rCRF(12-41), (cyclo 30-33) [D-Phe.sup.12, Nle.sup.21,38, Cys.sup.30,33 ]rCRF (12-41) and (bicyclo 20-23,30-33) [D-Phe.sup.12, Nle.sup.21,38, Lys.sup.23,33, Glu.sup.30 ]-rCRF(12-41).
Abstract:
The present invention is directed to a method for testing the susceptibility of a mammal to inflammatory diseases which comprises the steps of:administering to a mammal a compound selected from the group consisting of Type 1 mineralocorticoid receptor antagonists, opiate antagonists, estrogen antagonists or mixed estrogen agonists/antagonists, progesterone agonists; or a combination of an estrogen antagonist with one or a combination of a Type I glucocorticoid receptor antagonist, a Type II glucocorticoid agonist or a progesterone agonist which is effective in stimulating the hypothalamic-pituitary-adrenal (HPA) axis; andmeasuring the level of at least one hormone secreted by the hypothalamus, pituitary or adrenal glands of said mammal.The present invention is also directed to methods of treating inflammatory diseases.
Abstract:
Several known members of the corticotropin releasing factor (CRF) family have been synthesized and tested, including human and rat CRF which have the formula: H-Ser-Glu-Glu-Pro-Pro-Ile-Ser-Leu-Asp-Leu-Thr-Phe-His- Leu-Leu-Arg-Glu-Val-Leu-Glu-Met-Ala-Arg-Ala-Glu-Gln- Leu-Ala-Gln-Gln-Ala-His-Ser-Asn-Arg-Lys-Leu-Met-Glu- Ile-Ile-NH.sub.2. Peptides are herein disclosed that are potent competitive antagonists of CRF in mammals. One which has been found to be particularly potent is: H-D-Phe-His-Leu-Leu-Arg-Glu-Val-Leu-Glu-Nle-Ala- Arg-Ala-Glu-Gln-Leu-Ala-Gln-Gln-Ala-His-Ser-Asn- Arg-Lys-Leu-Nle-Glu-Ile-Ile-NH.sub.2. One that has shown particularly prolonged duration of potency is: H-D-Phe-His-Leu-Leu-Arg-Glu-Val-Leu-Glu-Nle-Ala- Arg-Ala-Glu-Gln-Leu-Ala-Gln-Gln-Ala-His-Ser-Asn- Arg-Lys-CML-Nle-Glu-Ile-Ile-NH.sub.2. These antagonists or pharmaceutically or veterinarily acceptable salts thereof, dispersed in a pharmaceutically or veterinarily acceptable liquid or solid carrier, can be administered to mammals, including humans, to achieve a prevent elevation of ACTH, .beta.-endorphin, .beta.-lipotropin, other products of the pro-opiomelanocortin gene and corticosterone levels and/or a lowering of brain mediated responses to stress over an extended period of time. They may also be used to affect mood, memory and learning, as well as diagnostically.
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
Abstract:
New compositions and their method of use for treating cardiovascular diseases primarily due to arteriosclerosis and atherosclerosis. These new compositions are prepared from a base Ringers injection to which is added a B-complex, hydrochloric acid, sodium ascorbate, pyridoxine hydrochloride, magnesium sulfate, adrenal cortex, magnesium chloride, thiamine, heparin sodium, calcium gluconate and calcium d-saccharate. Additional embodiments of the solution composition are also disclosed containing niacin, vitamin B.sub.12, ether, algae and amino acids. The compositions are useful in removing plaques from the interior walls of the arteries and veins, thereby improving blood supply to body tissues.
Abstract:
Novel peptides of ACTH activity, having a complete ACTH sequence from the N-terminal amino acid at least to the sixteenth amino acid, but containing optionally other amino acids in the place of the individual amino acids of the ACTH sequence, and always containing an Alpha -aminooxy acid in the place of the first amino acid have been prepared by deblocking the appropriate protected peptide derivatives. The new compounds, as well as their acid addition salts, derivatives or complexes possess potent ACTH activities and are resistant to enzymatic decomposition. They can be used in therapy with great advantages.

Abstract:
A HORMONOALY-ACITVE REACTION PRODUCT OF A PEPTIDIC HORMONE SUCH AS BOVINE GROWTH HORMONE, INSULIN, VASOPRESSIN, ADRENOCORTICOTROPIC HORMONE, AND THE LIKE, WITH A COPOLYMER OF AN OLEFINICALLY UNSATURATED POLYCARBOXYLIC ACID AND AN OLEFIN. THE HORMONE IS COVALENTLY BOUND TO THE POLYMER THROUGH AN AMINO, HYDROXYL, OR SULFHYDRYL GROUP OF THE HORMONE WHICH IS NOT ESSENTIAL FOR HORMONAL ACITIVITY. THESE PRODUCTS HAVE IMPROVED STABILITY, ARE SUBSTANTIALLY ODORLESS AND COLORLESS, AND HAVE PROLONGED ACITIVITY WHEN CONTRASTED WITH THE NATIVE HORMONE.
