Description
The cross reference of related application
The application requires to enjoy in the right of priority of the GB 0519957.5 of the U.S. Provisional Application sequence number 60/620,060 of application on October 19th, 2004 and application on September 30th, 2005, at this its full content is incorporated herein by reference.
Invention field
Put it briefly, the present invention relates to the CRF receptor antagonist and by to there being this class antagonist of warm-blooded mammals administration that needs to treat the method for disease.
Background of invention
First kind of corticotropin releasing factor(CRF) (CRF) is isolating by the sheep hypothalamus, and through being accredited as 41-amino acid peptide (people such as Vale, Science 213:1394-1397,1981).After this separated the CRF sequence of people and rat, they are identical after measured, but 7 CRF (Rivier etc., Proc.Natl.Acad.Sci.USA 80:4851,1983 that are different from sheep are arranged in its 41 amino-acid residues; People such as Shibahara, EMBO J.2:775,1983).
Found that CRF can cause internal secretion, nerve and function of immune system generation great shift.It is believed that CRF is the major physiological conditioning agent (people such as Vale who is discharged thyroliberin (" ACTH "), beta-endorphin and other pro-opiomelanocortin (" POMC ") derived peptide by prepituitary gland basic (basal) and irritability, Science 213:1394-1397,1981).In brief, it is believed that CRF is by being distributed widely in brain (people such as DeSouza, Science 224:1449-1451,1984), hypophysis (people such as DeSouza, Methods Enzymol.124:560,1986 in conjunction with a kind of; People such as Wynn, Biochem.Biophys.Res.Comm.110:602-608,1983), suprarenal gland (people such as Udelsman, Nature 319:147-150,1986) and spleen (Webster, E.L., and E.B.DeSouza, Endocrinology 122:609-617,1988) the plasma membrane acceptor in and start its biological effect.CRF acceptor and a kind of GTP-binding proteins matter coupling (Perrin etc., Endocrinology 118:1171-1179,1986), the latter mediates the increase (Bilezikjian that cAMP produces in the CRF-stimulated cells, L.M. and W.W.Vale, Endocrinology 113:657-662,1983).Now from rat (Perrin etc., Endo 133 (6): 3058-3061,1993) and human brain (Chen etc., PNAS 90 (19): 8967-8971,1993; Vita etc., FEBS 335 (1): 1-5,1993) acceptor of having cloned CRF.This acceptor is a kind of 415 amino acid whose protein that have, and wherein comprises seven membrane spaning domains.Identity between rat and the human sequence comparison shows that they have the homology (97%) of height on amino acid levels.
Except in the generation that stimulates ACTH and POMC, having the effect, it is believed that CRF can also coordinate much at stress internal secretion, autonomic response (autonomic) and behavior reaction (behavioralresponses), thereby may relate to the physiopathology of affective disorder.In addition, it is believed that in the contact of CRF between immunity, nervus centralis, internal secretion and cardiovascular systems it is a kind of media (people such as Crofford, J.Clin.Invest.90:2555-2564,1992 of key; People such as Sapolsky, Science 238:522-524,1987; People such as Tilders, Regul.Peptides 5:77-84,1982).In a word, one of seemingly critical central nervous system neurotransmitter of CRF, and integrate body to stress general reaction in played decisive role.
Directly to brain use the caused behavior of CRF, physiology and internal secretion reaction be exposed to stress the environment viewed reacting phase of Mammals down same.For example, cause behavior activation (people such as Sutton to intracerebral ventricle injection CRF, Nature 297:331,1982), continuous activation (people such as Ehlers appears in electroencephalogram, Brain Res.278:332,1983), the sympathoadrenal medullary substance approach (people such as Brown that is upset, Endocrinology 110:928,1982), heart rate and elevation of blood pressure (people such as Fisher, Endocrinology110:2222,1982), oxygen consumption increases people such as (, Life Sciences 30:207,1982) Brown, stomach and intestine are movable to be changed (people such as Williams, Am.J.Physiol.253:G582,1987), food consumption is suppressed (people such as Levine, Neuropharmacology 22:337,1983), sexual behaviour changes (people such as Sirinathsinghji, Nature 305:232,1983), and immunologic function suffer damage (people such as Irwin, Am.J.Physiol.255:R744,1988).Clinical data shows in addition, and in dysthymia disorders, anxiety relative disease and anorexia nervosa, brain may excessive secretion CRF (DeSouza, Ann.Reports in Med.Chem.25:215-223,1990).Therefore, clinical data shows that the CRF receptor antagonist may have been represented the depression and/or the anxiolytic medicament of a class novelty, can be used for treating the neuropsychiatric disorders (neuropsychiatric disorders) that shows as the CRF excessive secretion.
First-generation CRF receptor antagonist is that the peptide class is (referring to people such as for example Rivier, U.S. Patent number 4,605,642; People such as Rivier, Science 224:889,1984).Although these peptide proofs CRF receptor antagonist can weaken the pharmacological reaction to CRF really, peptide class CRF receptor antagonist still has the common disadvantage of peptide therapeutics, promptly comprises deficient in stability and limited Orally active.
Comprise have pyrazolo-the CRF antagonist of the compound of [1,5a]-pyrimidine nuclear is open in following patent and open application: WO9729109, US6313124, WO9803510, WO9938868, WO9808847, JP2000038350, EP1097709 and US6664261.In addition, among the JP10101671 of this nuclear in the application WO9535298 of anodyne, in the application JP10101672 of adenosine potentiator,, open in the application WO2001023387 of neuropeptide Y 1 antagonist, in the application WO2000044754 of accumulation of fat inhibitor and in the application WO2003101993 of hepatitis c viral replication inhibitor at nitric oxide synthase inhibitors.
Because CRF has the The above physiological meaning, therefore exploitation has significant CRF receptor-binding activity and biological activity small molecules that can antagonism CRF acceptor remains desired destination.This class CRF receptor antagonist will can be used for treating internal secretion, spirit and neurological disorder or disease, generally comprise and illness that stress be relevant.
Although realizing having obtained obvious improvement aspect the CRF adjusting by using the CRF receptor antagonist, this area still needs effective small molecules CRF receptor antagonist.Equally also need to contain the pharmaceutical composition of this class CRF receptor antagonist, and relate to its using method, for example be used for the treatment of and illness that stress be relevant.The present invention has finished these needs, and other relevant advantage also is provided.
