Definitions
- the present invention relates to substituted amino ketone compounds and salts thereof, hereinafter referred to as amino ketones, and to the use of the compounds for the preparation of a medicament for the in vivo inhibition of DP IV and/or DP IV- like enzymes.
- the invention relates especially to the use of the compounds for the preparation of a medicament for the treatment of impaired glucose tolerance, glucosuria, hyperlipidaemia, metabolic acidosis, diabetes mellitus, diabetic neuropathy and nephropathy and of sequelae caused by diabetes mellitus in mammals, for the treatment of metabolism-related hypertension and of cardiovascular sequelae caused by hypertension in mammals, for the prophylaxis or treatment of skin diseases and diseases of the mucosae, autoimmune diseases and inflammatory conditions, and for the treatment of psychosomatic, neuropsychiatric and depressive illnesses, such as anxiety, depression, sleep disorders, chronic fatigue, schizophrenia, epilepsy, nutritional disorders, spasm and chronic pain.
- psychosomatic, neuropsychiatric and depressive illnesses such as anxiety, depression, sleep disorders, chronic fatigue, schizophrenia, epilepsy, nutritional disorders, spasm and chronic pain.
- Dipeptidyl peptidase IV is a post-proline (to a lesser extent post-alanine, post-serine or post-glycine) cleaving serine protease found in various tissues of the body including kidney, liver, and intestine, where it removes dipeptides from the N- terminus of biologically active peptides with a high specificity when proline or alanine form the residues that are adjacent to the N-terminal amino acid in their sequence.
- DP IV Dipeptidyl peptidase IV
- DP IV was originally believed to be the only membrane-bound enzyme specific for proline as the penultimate residue at the amino-terminus of the polypeptide chain.
- DP IV-like enzymes which are identified so far, are e.g.
- fibroblast activation protein ⁇ dipeptidyl peptidase IV ⁇ , dipeptidyl aminopeptidase-like protein, N-acetylated ⁇ -linked acidic dipeptidase, quiescent cell proline dipeptidase, dipeptidyl peptidase II, attractin and dipeptidyl peptidase IV related protein (DPP 8), DPL1 (DPX, DP6) and DPL2, and are described in the review articles by Sedo & Malik (Sedo & Malik, Dipeptidyl peptidase IV-like molecules: homologous proteins or homologous activities?
- DP IV-like enzymes are disclosed in WO 01/19866, WO 02/34900 and WO02/31134.
- WO 01/19866 discloses novel human dipeptidyl aminopeptidase 8 (DPP8) with structural und functional similarities to DP IV and fibroblast activation protein (FAP).
- WO 02/34900 discloses a novel dipeptidyl peptidase 9 (DPP9) with significant homology to the amino acid sequences of DP IV and DPP8.
- WO 02/31134 discloses three DP IV-like enzymes, DPRP1 , DPRP2 and DPRP3. Sequence analysis revealed that DPRP1 is identical to DPP8 as disclosed in WO 01/19866, that DPRP2 is identical to DPP9 and that DPRP3 is identical to KIAA1492 as disclosed in WO 02/04610.
- DP IV is responsible for inactivating glucagon-like peptide-1 (GLP-1 ) and glucose-dependent insulinotropic peptide also known as gastric-inhibitory peptide (GIP). Since GLP-1 is a major stimulator of pancreatic insulin secretion and has direct beneficial effects on glucose disposal, in WO 97/40832 and US 6,303,661 inhibition of DP IV and DP IV-like enzyme activity was shown to represent an attractive approach for treating non-insulin-dependent diabetes mellitus (NIDDM).
- NIDDM non-insulin-dependent diabetes mellitus
- DP IV and DP IV-like enzyme activity for cleaving such substrates in vivo can serve to suppress undesirable enzyme activity effectively both under laboratory conditions and in pathological conditions of mammals.
- Diabetes mellitus type II also diabetes of old age
- hyperglycaemia and its associated causes and sequelae are treated according to the current state of the art by administering insulin (for example material isolated from bovine pancreas or also material obtained by genetic engineering) to those affected, in various forms of administration.
- DPIV-inhibitors may be useful for the treatment of impaired glucose tolerance and diabetes mellitus (International Patent Application, Publication Number WO 99/61431 , Pederson RA et al, Diabetes. 1998 Aug; 47(8): 1253-8 and Pauiy RP et al, Metabolism 1999 Mar; 48(3):385-9).

- low molecular weight dipeptidyl peptidase IV inhibitors are agents such as tetrahydroisoquinolin-3-carboxamide derivatives, N-substituted 2-cyanopyrroles and -pyrrolidines, N-(N'-substituted glycyl)-2-cyanopyrrolidines, N- (substituted glycyl)-thiazoldines, N-(substituted glycyl)-4-cyanothiazoldines, amino- acyl-borono-prolyl-inhibitors and cyclopropyl-fused pyrrolidines.
- Inhibitors of dipeptidyl peptidase IV are described in US 6,011 ,155; US 6,107,317; US 6,110,949; US 6,124,305; US 6,172,081 ; WO 99/61431 , WO 99/67278, WO 99/67279, DE 198 34 591 , WO 97/40832, DE 196 16 486 C 2, WO 98/19998, WO 00/07617, WO 99/38501 , WO 99/46272, WO 99/38501 , WO 01/68603, WO 01/40180, WO 01/81337, WO 01/81304, WO 01/55105, WO 02/02560 and WO 02/14271, WO 02/076450, WO 02/051836, EP 02290755.4 and WO 02/38541, the teachings of which are herein incorporated by reference in their entirety concerning these inhibitors, their uses, definition and their production.
- the problem of the invention is therefore to provide new compounds for the treatment of, for example, impaired glucose tolerance, glucosuria, hyperlipidaemia, metabolic acidosis, diabetes mellitus, diabetic neuropathy and nephropathy and of sequelae caused by diabetes mellitus in mammals, metabolism-related hypertension and cardiovascular sequelae caused by hypertension in mammals, for the prophylaxis or treatment of skin diseases and diseases of the mucosae, autoimmune diseases and inflammatory conditions, and for the treatment of psychosomatic, neuropsychiatric and depressive illnesses, such as anxiety, depression, sleep disorders, chronic fatigue, schizophrenia, epilepsy, nutritional disorders, spasm and chronic pain, and a simple method for the treatment of those diseases.

- Peptide mimetics per se are known to a person skilled in the art. They are preferably defined as compounds which have a secondary structure like a peptide and optionally further structural characteristics; their mode of action is largely similar or identical to the mode of action of the native peptide; however, their activity (e.g. as an antagonist or inhibitor) can be modified as compared with the native peptide, especially vis a vis receptors or enzymes. Moreover, they can imitate the effect of the native peptide (agonist).
- Examples of peptide mimetics are scaffold mimetics, non-peptidic mimetics, peptoides, peptide nucleic acids, oligopyrrolinones, vinylogpeptides and oligocarbamates. For the definitions of these peptide mimetics see Lexikon der Chemie, Spektrum Akademischer Verlag Heidelberg, Berlin, 1999.
- the aim for using these mimetic structurs is increasing the activity, increasing the selectivity to decrease side effects, protect the compound (drug) against enzymatical degradation for prolongation of the effect.
- the endogenous (or additionally exogenously administered) insulinotropic peptides GIP ⁇ . 42 and GLP-1 -36 (or GLP-1 7-37 or analogues thereof), for example, are broken down to a lesser degree by DP IV or DP IV-like enzymes.
- the compounds of the present invention lower or inhibit the activity of DP IV or DP IV-like enzymes at least by about 10, preferably about 50, more preferably about 75, 90 or 100% and prolong the half live of their substrates in a mammal by at least about 2fold, preferably about 3fold, more preferably about 4fold, 5fold or higher relative to the absence of the compound and hence the reduction in the concentration of those peptide hormones and their analogues is reduced or delayed.
- the invention is based, therefore, on the finding that a reduction of the DP IV or DP IV-like enzyme activity in the bloodstream results in influencing of the blood sugar level.
- the compounds of the present invention are therefore useful for the treatment of impaired glucose tolerance, glucosuria, hyperlipidaemia, metabolic acidosis, diabetes mellitus, diabetic neuropathy and nephropathy and of sequelae caused by diabetes mellitus in mammals.
- the compounds of the present invention lower or inhibit the degradation of other substrates of DP IV or DP IV-like enzymes and are therefore useful for the treatment of metabolism-related hypertension and of cardiovascular sequelae caused by hypertension in mammals, for the prophylaxis or treatment of skin diseases and diseases of the mucosae, autoimmune diseases and inflammatory conditions, and for the treatment of psychosomatic, neuropsychiatric and depressive illnesses, such as anxiety, depression, sleep disorders, chronic fatigue, schizophrenia, epilepsy, nutritional disorders, spasm and chronic pain.
- psychosomatic, neuropsychiatric and depressive illnesses such as anxiety, depression, sleep disorders, chronic fatigue, schizophrenia, epilepsy, nutritional disorders, spasm and chronic pain.
- the oral administration of the high-affinity, low-molecular-weight enzyme inhibitors of the invention is a more cost-effective alternative, for example, to invasive surgical techniques in the treatment of pathological symptoms.

All pharmaceutically acceptable acid addition salt forms of the compounds of the present invention are intended to be embraced by the scope of this invention
- the compounds according to this invention may accordingly exist as enantiomers. Where the compounds possess two or more chiral centers, they may additionally exist as diastereomers. It is to be understood that all such isomers and mixtures thereof are encompassed within the scope of the present invention. Furthermore, some of the crystalline forms of the compounds may exist as polymorphs and as such are intended to be included in the present invention. In addition, some of the compounds may form solvates with water (i.e. hydrates) or common organic solvents, and such solvates are also intended to be encompassed within the scope of this invention.
- the compounds, including their salts, can also be obtained in the form of their hydrates, or include other solvents used for their crystallization.
- the invention accordingly relates to inhibitors of dipeptidyl peptidase IV (DPIV) and DP IV-like enzyme activity and to their use for lowering the blood sugar level below the glucose concentration characteristic of hyperglycaemia in the serum of a mammal.

- the compounds of the present invention may be used in the form prodrugs.
- these prodrugs can be used as inhibitors of DP IV and DP IV-like enzymes and it is possible to define the site of their action, the time of onset of their action and the duration of action precisely.
- Upon administration such prodrugs are cleaved, for example by suitable enzymes, and the active inhibitors are released.
- the active inhibitors can be released both by chemical and enzymatic mechanisms.
- esterases, proteases and peptidases serve to release the active inhibitors from the prodrugs according to the invention.
- esterases, proteases, etc. are disclosed, for example, in WO 97/45117, US 5433955, US 5614379 and US 5624894.
- Preferred proteases are aminopeptidases, dipeptidyl aminopeptidases, endoproteases, and endopeptidases.
- Especially preferred proteases for the release of the active inhibitors from the prodrugs of the present invention are aminopeptidase N, aminopeptidase P, pyroglutaminyl aminopeptidase, dipeptidyl peptidase IV and dipeptidyl peptidase IV- like enzymes.
- the released active inhibitors can interact with the DP IV and DP IV-like enzymes.
- the above-mentioned insulinotropic peptides are broken down to a lesser degree and the effectiveness of insulin is thereby increased.
- the present invention uses the concept to stabilize unstable inhibitors by masking them in prodrug form.
- the properties of the active inhibitors according to the invention can be designed in such a way that the deactivation time of the DP IV-inhibitors e.g. by intramolecular cyclisation after their release from the prodrugs, is definable. ln particular, the prodrugs of the compounds of the invention are advantageous in that the active inhibitors of DP IV and DP IV-like enzymes are released according to individual patients' needs.
- a prodrug of a compound of the invention interacts with a DP IV molecule or a aminopeptidase N molecule, it is cleaved by these enzymes and the active inhibitor is released.
- the active inhibitor will inhibit DP IV and/or DP IV-like enzymes so that DP IV itself cannot cleave any further compounds for a defined time.
- the remaining prodrugs are not degraded during this defined time and thus, constitute an inhibitor reservoir until the concentration of DP IV molecules or aminopeptidase N molecules rises again or active inhibitor molecules are eliminated or inactivated.
- prodrugs has the further advantage that each organism will release exactly that amount of active inhibitor that is necessary to inhibit that amount of DP IV molecules, which is present in the body of the respective organism.

- the compounds according to the present invention are transported through the mucosa of the small intenstine without delay, for example simultaneously with nutrient intake. Moreover, the site of action, at which the active DP IV-inhibitors are released can also be controlled by the structure of the prodrugs.
- the compounds of the present invention are useful in lowering or inhibiting DP IV and DP IV- like enzyme activity at least by about 10, preferably about 50, more preferably about 75, 90 or 100% and prolong the half live of their substrates in a mammal by at least about 2fold, preferably about 3fold, more preferably about 4fold, 5fold or higher relative to the absence of the compound and hence the reduction in the concentration of those peptide hormones and their analogues is reduced or delayed.
