Description
TITLE OF THE INVENTION
SUBSTITUTED PERIMIDINONES AS NEUROTENSIN ANTAGONISTS
INTRODUCTION OF THE INVENTION
This invention is concerned with a method of treating disease states mediated by neurotensin by the administration to a patient in need of treatment of a therapeutically effective amount of a neurotensin antagonist which is a substituted pyrimidinone of structural formula I:
As neurotensin antagonists these compounds find utility in the treatment of CNS dysfunctions such as psychoses, depression, cognitive dysfunction, such as Alzheimer's disease, anxiety, tardive dyskinesia, drug dependency, panic attack and mania.
The neurotensin antagonist property also imparts to the compounds utility in GI disorders such as gastroesophageal reflux disorder (GERD), irritable bowel syndrome, diarrhea, cholic, ulcer, GI tumors, dyspepsia, pancreatitis, esophagitis and gastroparesis. The known ability of neurotensin to release mast cell histamine indicates that antagonists will be useful in the treatment of allergic and inflammatory conditions.
BACKGROUND OF THE INVENTION
Neurotensin (NT) is a tridecapeptide hormone (pGlu-Leu-Tyr-Glu-Asn-Lys-Pro-Arg-Arg-Pro
Tyr-Ile-Leu-OH), originally isolated from the bovine hypothalamus [Carraway, R. and Leeman, S. E., J.
Biol. Chem.,248, 6854 (1973)], has subsequently been shown to be distributed in the brain [Uhl, G. R., ffe al., Proc. Natl. Acad. Sci. USA, 74, 4059-4063 (1977)), gastrointestinal tract [ 1). Kitabgi, P.,
Carraway, R. and Leeman, S. E., J. Biol. Chem., 251, 7053 (1976); 2). Caraway, R., Kitabgi, P., and
Leeman, S. E., J. Biol. Chem., 253, 7996 (1978); 3).
llelmstadler, V., Tadgner, C., Feurle, G. E. and
Frossman, W. G., Histochemistry, 53, 35-41 (1977)] and pancreas [Feurle, G. E. and Niestroj, S.,
Pancreas, 6, 202-207 (1991) and references cited therein] of various animals including human [Mai, J.
K., et al., Neuroscience, 22, 499-524 (1987)1.
Although the physiological role of neurotensin has not yet been clearly understood, this endogenous peptide participates in a wide spectrum of central.

Hormone Res., 38, 93-132 (1982)] biological functions.
Neurotensin is also known to release mast cell histamine, indicating that antagonists will be useful in the treatment of allergic and inflammatory conditions, as well. [See, Rossei, S.S. and Miller,
R.J., Life Sci., 31, 509-516 (1982) and Kurose, M.
and Saeki, K., Eur. J. Pharmacol., 76, 129-136 (1981).]
Neurotensin, like most other peptides, is unable to cross the blood-brain barrier (BBB).
However, certain peripheral effects of neurotensin have been observed after central administration of the peptide [Prange, A. J. and Nemeroff, C. B.,
Annal. NY Acad. Sciences, 400, 368-391 (1982)]. The direct application of neurotensin into the brain causes hypothermia, potentiation of barbiturate induced sedation, catalepsy, antinociception, blockade of psychostSimulant-induced locomotor activity and reduced food consumption. In the central nervous system (CNS), neurotensin behaves as a neurotransmitter or neuromodulator [1) Uhl, G. R.
and Snyder, S. H., Eur. J. Pharmacol., 41,'89-91 (1977); 2) Uhl, G. R., Annal. NY Acad. Sciences, 400, 132-149 (1982)], and has been shown to have close anatomical and biochemical associations with the dopaminergic (DA) system [Nemeroff, C. B.,-et al.
Annal. NY Acad. Sciences, 406, 330-344 (1982)].
Neurotensin increases the synthesis and the turnover of DA in rat brain. Acute and chronic treatment with clinically efficacious antipsychotic drugs (e.g., haloperidol, chloropromazine) have consistently demonstrated an increase in neurotensin concentrations in the nucleus accumbens and striatum while phenothiazines that are not antipsychotics did not produce this increase. Behaviorally, neurotensin, after central administration, mimics the effects of systemically administered neuroletics. However, unlike classical neuroleptics (which primarily act on
D2 receptors), neurotensin fails to bind to dopamine receptors or inhibit cAMP accumulation following DA receptor activation. Neurotensin does not block the stereotypy induced by DA agonists.The post-mortem studies of patients with schizophrenia showed an increase in the level of neurotensin in the Brodman's area 32 of human brain [Nemeroff, C. B., et. al.,
Science., 221, 972-975 (1983) and references cited therein], which suggest possible roles of neurotensin in the pathophysiology of this disease.
Neurotensin receptors have also been implicated in
Parkinsonrs disease and progressive supranuclear palsy [Chinaglia, GS et al., Neuroscience, 39, 351-360 (1990)].
Of the total body neurotensin in many mammalian species, more than 80% is present in the gastrointestinal tract, especially in the distal small' intestine in the endocrine like N-cells. In the gut, neurotensin stimulates pancreatic secretion [Sakamoto, T.,et al, Surgery, 96, 146-53 (1984)], inhibits gastric acid secretion and gastric emptying [ Blackburn, A. M., Lancet, 1, 987-989 (1980)].
Neurotensin also stimulates the growth of small intestinal mucosa in an isolated defunctional loop of jejunum, which suggests a direct systemic effect of neurotensin in the gut. In addition, neurotensin can stimulate pancreatic exocrine secretion in mammals [Iwatsuki, K.,.et al., Clin. Expt. Pharmacol.
Phvsiol., 18, 475-481 (1991) and references cited therein].
From the structural work, it is evident that the biological activity of neurotensin resides within the carboxy terminal five or six amino acid residues.- The C-terminal hexapeptide NT8-13 has displayed full biological activity of the tridecapeptide. In contrast, all amino terminal partial sequences are essentially inactive [Leeman, S. E. and Carraway, R.
E., Annal. NY Acad. Sciences, 400, 1-16 (1982)]. The
C-terminal COOH group and two Arg residues are essential for the biological activity of NT8-13 as well as neurotensin. L-amino acids are required at positions-9,10,11 and 13, and only Arg8 can be replaced by D-Arg without loss of any activity. At the position-ll, an aromatic amino acid is essential.
Similarly, alkyl side-chains of Ilex2 and Leul3 are also necessary for Pull biological activity [Kitabgi,
P., Annal. NY Acad. Sciences, 400, 37-53 (1982)].
Most of the analogues of neurotensin examined generally behaved as agonists. However, two analogues
D-Trpll-NT and Tyr(Me)11-NT have displayed partial antagonist activity tRioux, F. R.,et al., Eur. J.
Pharmacol., 66, 373-379 (1980)).
The compounds useful in the novel method of treatment of this invention are known in the art having been published in European Patent Application
EP 419,048 (Merck & Co., Inc.) on March 27, 1991, where they are alleged to be angiotensin II receptor antagonists useful in the treatment of hypertension and ocular hypertension.
Although there are reports of peptidic neurotensin antagonists, they are unstable and not orally active and none are clinically available.
There are no reports of nolf-peptidic neurotensin antagonists.
Now with this invention there are provided non-peptidic neurotensin antagonists.

Treaty as International Application WO 9115479 (Merck & Co.). The above mentioned application discloses the compounds of this invention where they are alleged to be angiotensin II receptor antagonists useful in the'treatment of hypertension and ocular hypertension.
The reactions are performed in a solvent appropriate to the reagents and materials employed and suitable for the transformation being effected. It is understood by those skilled in the art of organic synthesis that the functionality present on the heterocycle and in the reactants being employed should be consistent with the chemical transformations being conducted. Depending upon the reactions and techniques employed, optimal yields may require changing the order of synthetic steps or use of protecting groups followed by deprotection.
The compounds useful in the novel method treatment of this invention form salts with various inorganic and organic acids and bases which are also within the scope of the invention. Such salts include ammonium salts, alkai metal salts like sodium and potassium salts, alkaline earth metal salts like the calcium and magnesium salts, salts with organic bases; e.g., dicyclohexylamine salts, N-methyl-Dglucamine, salts. with amino acids like arginine,.
lysine, and the like. Also, salts with organic and inorganic acids may be prepared; e.g., HC1, HBr,
H2S04, H3P04, methanesulfonic, toluenesulfonic, maleic, fumaric, camphorsulfonic.
The salts can be formed by conventional means,such as by reacting the free acid or free base forms of the product with one or more equivalents of the appropriate base or acid in a solvent or medium in which the salt is insoluble, or in a solvent such as water which is then removed in vacuo or by freeze-drying or by exchanging the cations of an existing salt for another cation on a suitable ion exchange resin.
