FROPARGYLAMINO INDAN DERIVATIVES AND PROPARGYLAMINO
TETRALIN DERIVATIVES AS BRAIN-SELECTIVE MAO INHIBITORS
This .application claims the benefit of U.S, Serial No.
10/085,674, filed February 27, 2002, the contents of which are hereby incorporated by reference.
Throughout this application, various references are referenced by short citations within parenthesis. Full citations for these references may be found at the end of the specification, immediately preceding the claims. These references, in their entireties, are hereby incorporated by reference to more fully describe the state of the art to which this invention pertains.
Field of the Invention The subject of this invention provides for derivatives of propargylaminoindans and propargylaminotetralins that are irreversible inhibitors of the enzyme monoamine oxidase A and/or B and also for prodrugs far the administration of these compounds. Such compounds may be useful in the treatment of Parkinson's disease, Alzheimer's disease, depression and other neurological disorders.
Background of the Invention The enzyme monoamine oxidase (MAO) plays an essential role in the metabolic degradation of important amine neurotransmitters including dopamine, serotonin and noradrenaline. Thus, agents that inhibit MAO are of potential therapeutic benefit for a variety of neurological disease indications, including Parkinson's disease, Alzheimer's~disease, depression, epilepsy, narcolepsy, amyotrophic lateral sclerosis (ALS), etc. (Szelnyi, I.; Bentue-Ferrer et al.; .Loscher et al.; White et al.; U.S.
Patent No. 5,744,500). Other diseases and conditions which have _7_ been associated with toxic levels of monoamine oxidase-B are memory disorders (The interaction of L-deprenyl and scopolamine on spatial learning/memory in rats), panic, post-traumatic stress disorder (PTSD), sexual dysfunction, attention deficit and hyperactivity syndrome (ADHD)(Potential applications for monoamine oxidase B inhibitors), attention deficit disorder (ICleywegt), and Tourette's syndrome (Treatment of Tourette's:
Overview).
Many inhibitors of MAO are chiral molecules (U~.S. Patent No.
5,744,500). Although one enantiomer often shows some stereoselectivity in relative potency towards MAO-A and -B, a given enantiomeric configuration is not always more selective than its isomer in discriminating between MAO-A and -B
(Hazelhoff et al., Naunyn-Schmeideberg's Arch. Pharmacol.).
MAO inhibitors can also be classified as reversible inhibitors which inhibit the enzyme by a competitive mechanism or as irreversible inhibitors which are generally mechanism based (suicide inhibitors) (Dostert). For example, moclobemide is a reversible MAO-A-specific inhibitor (Fitton et al.) developed as an anti-depressant. Likewise, rasagiline (U.S. Patent No.
5,744,500) and selegiline,(Chrisp et al.) are MAO-B-selective irreversible inhibitors.
Irreversible ,inhibitors have the advantage of lower, less frequent dosing since their MAO inhibition is not based directly on the drugs' pharmacokinetic behavior, but rather on the de novo regeneration of the MAO enzyme.
MAO also plays an essential role in the oxidative deamination of biogenic and food-derived amines, both in the central nervous system and in peripheral tissues.. MAO is found in two functional isoenzyme forms, MAO-A and MAO-B, each of which shows preferential affinity for substrates and specificity toward inhibitors. Thus, MAO-A preferentially oxidizes serotonin, noradrenaline and adrenaline, whereas MAO-B preferentially metabolizes phenylethylamine. Dopamine is a substrate fpr both forms of the enzyme(Szelenyi, I.).
N-Propargyl-(1R)-aminoindan is known to be a potent B-selective inhibitor of MAO (U. S. Patent No. 5,457,133). Various derivatives of this compound have been prepared and shown to have varying degrees of potency and selectivity for the inhibition of MAO-A andlor -B. There is no currently accepted theory explaining the effect of structure on the activity (SAR) of the various substituted propargylaminoindans.
The dopamine agonistic activity and MAO inhibitory properties of 7-(methyl-prop-2-ynylamino)-tetralin-2-of and 7-(methyl-prop-2-ynylamino)-tetralin-2,3-diol have been reported (Hazelhoff et al., Eur. J. Pharmacol.). The details of the synthesis of these compounds have not been published, however.
?0 6,7-di-0-benzoyl-2-aminotetralin has been reported as a prodrug of the dopaminergic agonist 6,7-di-hydroxy-2-aminotetralin (Horn et al.). However, no N-propargyl derivatives were reported and the compounds were not shown to have MAO inhibitory or neuroprotective activities.
7-(propyl-prop-2-ynylamino)-tetralin-2-of has been reported as an intermediate in the preparation .of 7-[(3-iodoallyl)-propylamino]-tetralin-2-ol. Only the latter has been pharmacologically characterized as D3-dopamine receptor ligand (Churnpradit et al.). No other N-alkyl substituents were described.
Florvall et al. report the preparation of amino acid-based prodrugs of amiflamine analogues. Amiflamine is a reversible MAO-A inhibitor. , PCT International Application No. PCT/US97/24155 concerns carbamate aminoindan derivatives, including propargylamines, as inhibitors of MAO-A and M.AO-B for the treatment of Alzheimer's disease and other neurological conditions. However, the compounds of PCT/US97/24155 are not selective for MAO over acetylcholinesterase ("AChE"). Thus, the compounds generally inhibit acetylcholinesterase along with MAO.
Acetylcholinesterase inhibition is a route implicated in certain neurological disorders, but is a different route from the route of MAO inhibition.
U.S. Patent No. 6,303,650 discloses derivatives of 1-aminoindan as selective MAO B inhibitors that additionally inhibit acetylcholinesterase. The reference teaches that its compounds can be used to treat depression, Attention Deficit Disorder (ADC), Attention Deficit and Hyperactivity Disorder (ADHD), Tourette's Syndrome, Alzheimer's Disease and other dementias such as senile dementia, dementia of the Parkinson's type., vascular~dementia and Lewy body dementia.
Many irreversible MAO inhibitors contain the propargyl amine functionality. This pharmacophore is responsible for the MAO
inhibitory activity of such compounds. Some propargylamines have been shown to have neuroprotective/neurorescue properties independent of their MAO inhibition activity (U.S. Patent No.
4,844,033; Krageten et al.).
PCT International Application No. PCTlIL96/00115 relates to pharmaceutical compositions comprising racemic, (S), and (R)-N-propargyl-1-aminoindan. (R)-N-propargyl-1-aminoindan selectively inhibits MAO-B in the treatment of Parkinson's disease and other neurological disorders(PCT/IL96/00115).
Derivatives of 1-aminoindan, including propargyl aminoindan, and their salts are described in many U. S . patents (U. S . . Patents No.
5,639,913, 5,877,221, 5,880,159, 5,877,218, 5,914,349, 5,994,408) and a PCT International Application (PCT/US95100245).
These references disclose racemic, R and S enantiomer~ of 1-aminoindan derivatives for the treatment of Parkinson's disease S and other neurological conditions (U. S. Patents No. 5,639,913, 5,87.7,221, 5,880,159, 5,877,218, 5,914,349, 5,994,408, PCT/US95/00245).
pCT International Application No. PCT/US97/24155 concerns 10. aminoindan derivatives, including propargyl aminoindan, as inhibitors of MAO-A and MAO-B for the treatment of Parkinson's disease and other neurological conditions. The publication reveals that the disclosed compounds exhibit a greater selectivity for MAO-A and MAO-B in the brain than in the liver 15 or intestine.
U.S. Patent No. 6,316,504 discloses that the R(+) enantiomer of N-propargyl-1-aminoindan is a selective irreversible inhibitor of MAQ-B. The patent indicates that (R)-20 N-propargyl-1-aminoindan is useful for the treatment of Parkinson's disease, a memory disorder, dementia, depression, hyperactive syndrome, an affective illness, a neurodegenerative disease, a neurotoxic injury, stroke, again ischemia, a head trauma injury, a spinal traumG injury, neurotrauma, 25 schizophrenia, an attention deficit disorder, , multiple sclerosis, and withdrawal symptoms.
European Patent No. 436492 discloses the R enantiomer of N-propargyl-1-aminoindan as a selective irreversible inhibitor of 30 MAO-B in the treatment of Parkinson's disease and other neurological conditions. Numerous U.S. patents also relate to the MAO B inhibition of (R) -N-propargyl-1-aminoindan and its use for treating patients suffering from Parkinson's Disease and other neurological disorders (U. S. Patents No. 5,387,612, 35 5,453,446, 5,457,13.3, 5,519,061, 5,532,415, 5,576,353, 5,668,181, 5,744,500, 5,786,390 and 5,891,923).
PCT International Application No. PCT/IL97/00205 disclpses 5-(-)-N-propargyl-1-aminoindan or a pharmaceutically acceptable salt thereof for the treatment of a neurological disorder of neurotrauma or for improving memory. The compounds were found to be neuroprotective, but not inhibitory of MAO-A or MAO-B
(PCT/IL97/00205).
U.S. Patent No. 5,486,541 provides N-propargyl-1-amonoindan monofluorinated in the phenyl ring as selective inhibitors. of MAO-B. These compounds are presented as useful in the.treatment of Parkinson's disease, memory disorders, dementia of the Alzheimer's type, depression and the hyperactive .syndrome in children.
Among.the many derivatives of propargylaminoindan mentioned in the prior art are hydroxy-propargylaminoindans. U.S. Patent No.
3,513,244 lists some racemic N-propargylamino indanols and tetralinols for use as antihypertensives. These compounds are not exemplified chemically and are not pharmacologically, characterized (U.S.'Patent No. 3,513,244).
N-propargylamino indanol also appears in E.P. 267024 as a hydrofluorene derivative, i.e., 3-amino-4-indanol (7-OH
fluorene). The hydrofluorene derivatives and salts in E.P.
267024 are employed as cerebral activators in.the treatment of anoxemia and hypoxemia. In addition, such derivatives help prevent arrhythmia and heart failure caused by lack of oxygen (E.P. 267024). The derivatives also act as antioxidants and cholinergic nerve system activating agents (E. P. 267024).

The subject invention thus discloses various derivatives and isomers of hydroxylated propargylamino indan and tetralin which have surprisingly varied potency and selectivity for MAO
inhibition. The subject invention also provides modifications of the hydroxy compounds which have surprisingly varied MAO
inhibitory properties depending upon the substitution pattern, however, the hydroxy compound is always a m~re potent inhibitor than the modified version. Thus, the modified version may be considered a prodrug of the more active hydroxy compound into which it will be metabolized in vivo.
In one embodiment of the invention, the prodrug compound is a carboxylic acid ester of the hydroxy compound. In another embodiment, the parent is a carbamate derivative of the hydroxy compound.
As discussed above, carbamate propargylamino indans and tetralins have been reported in PCT International Application No. PCT/US97/24155 as both MAO inhibitors and AchE inhibitors.
However, it is a further embodiment of this invention that such a prodrug compound will not be a potent inhibitor of AchE (ICS, >500 micromolar), and the ICSO for MAO-A inhibition of the corresponding hydroxy metabolite be at least 100 times more potent than the prodrug.
In one embodiment, the compounds are dihydroxy derivatives of propargylamino indan .or tetralin. These derivatives are expected to be antioxidants, as well as MAO inhibitors. In another embodiment, the subject invention provides ester prodrugs.
Thus, the subject invention provides esters or carbamat~es of propargylamino indanols, propargylamino indandiols, propargylamino tetralinols or propargylamino tetralindiols, and may be prepared by methods of esterification or carbamoylation of hydr~oxy compounds. Ester derivatives (Figur.e 1) when Ra equals hydrogen were prepared by reacting the propargylamino indanols with acyl chlorides in the presence of a strong organic acid such as trifluoroacetic acid or an acylation catalyst such as 4-dimethylaminopyridine (DMAP), with or without an inert orcranic solvent such as chloroform. Compounds when R3 equals hydrogen were prepared either by direct acylation as described above, or by first N-protecting the amine moiety, e.g. , by a tert-butoxycarbonyl (Boc) group, followed by acylation as above, and finally removing the protecting group. The preparation of compounds of the subject invention which are carbamates is described in PCT/US97/24155.
Propargylamino indanols may :be prepared by reacting amino indanols with propargyl bromide in a polar organic solvent such as N,N-dimethylacetamide or acetonitrile in the presence of a.
base such as potassium carbonate.

The subject invention thus discloses various derivatives and isomers of hydroxylated propargylamino indan and tetralin which have surprisingly varied potency and selectivity for MAO
inhibition. The subject invention also provides modifications of the hydroxy compounds which have surprisingly varied MAO
inhibitory properties depending upon the substitution pattern, however, the hydroxy compound is always a m~re potent inhibitor than the modified version. Thus, the modified version may be considered a prodrug of the more active hydroxy compound into which it will be metabolized in vivo.
In one embodiment of the invention, the prodrug compound is a carboxylic acid ester of the hydroxy compound. In another embodiment, the parent is a carbamate derivative of the hydroxy compound.
As discussed above, carbamate propargylamino indans and tetralins have been reported in PCT International Application No. PCT/US97/24155 as both MAO inhibitors and AchE inhibitors.
However, it is a further embodiment of this invention that such a prodrug compound will not be a potent inhibitor of AchE (ICS, >500 micromolar), and the ICSO for MAO-A inhibition of the corresponding hydroxy metabolite be at least 100 times more potent than the prodrug.
In one embodiment, the compounds are dihydroxy derivatives of propargylamino indan .or tetralin. These derivatives are expected to be antioxidants, as well as MAO inhibitors. In another embodiment, the subject invention provides ester prodrugs.
Thus, the subject invention provides esters or carbamat~es of propargylamino indanols, propargylamino indandiols, propargylamino tetralinols or propargylamino tetralindiols, and may be prepared by methods of esterification or carbamoylation of hydr~oxy compounds. Ester derivatives (Figur.e 1) when Ra equals hydrogen were prepared by reacting the propargylamino indanols with acyl chlorides in the presence of a strong organic acid such as trifluoroacetic acid or an acylation catalyst such as 4-dimethylaminopyridine (DMAP), with or without an inert orcranic solvent such as chloroform. Compounds when R3 equals hydrogen were prepared either by direct acylation as described above, or by first N-protecting the amine moiety, e.g. , by a tert-butoxycarbonyl (Boc) group, followed by acylation as above, and finally removing the protecting group. The preparation of compounds of the subject invention which are carbamates is described in PCT/US97/24155.
Propargylamino indanols may :be prepared by reacting amino indanols with propargyl bromide in a polar organic solvent such as N,N-dimethylacetamide or acetonitrile in the presence of a.
base such as potassium carbonate. N-Methyl, N-pr.oparaylamino indanols may be prepared by reductive alkylation of propargylamino indanols by methods known to those skilled in the art, e.g., with NaCNBH, and paraformaldehyde. Alternatively, N-methyl,N-propargylamino indanols were prepared by first methylating amino indanols either by NaCNBH3/paraformaldehyde or by ethyl formate followed by LiAlH~ reduction, and then reacting the N-methylamino indanols thus obtained with propargyl bromide as described above.
The N-propargyl derivatives of, inter alia, 3-amino-indan-4-ol, 1-amino-indan-4-ol, 3-amino-indan-5-of and 7-amino-5,6,7,8-tetrahydro-naphthalen-2-of were prepared.
Compounds of the subject invention with both R1 and Rz equal to OCOR4 (see Figure 2, compound numbered 9) were prepared by propargylation of 5,6-di-0-benzoyl-1-methylamino-1-indan (Figure 2, compound numbered 8), as described above. 5,6-Di-O-benzoyl-1-methylamino-1-indan (Figure 2, compound numbered 8) was prepared from 5;6-bis-benzyloxy-1-indanone 3 as follows:
1) reductive amination of the compound numbered 3 in Figure 2 as described above gave 5,6-bis-benzyloxy-1 indanyl)methylamine (Figure 2, compound numbered 4);
2) the compound numbered 4 in Figure 2 was debenzylated by catalytic hydrogenation and protected by the Boc group to give N-Boc-1-methylamino-indan-5,6-diol (Figure 2, compound numbered 6); and 3) Compound 6 in Figure 2 was esterified as described above and the protecting group removed as previously described to give 5,6-di-0-benzoyl-1-methylamino-1-indan (Figure 2, compound numbered 8).
The diester tetralin derivative numbered 12 (Figure 3) was prepared by esterification of the dihydr.oxy tetralin numbered 11 (Figure 3).

The reaction mixture was filtered, diluted with water (200 ml) and extracted with toluene (4 x 100 ml). The organic extracts were combined, dried and evaporated to dryness under reduced pressure. The residue was then subjected to flash column chromatography (hexane . EtOAc, 1:1).~ The free base was optionally converted to an acid addition salt.
Alternatively, the' propargylation reaction was run in acetonitrile at elevated temperature, e.g., 60°C ~or 4 hours.
The reaction mixture was then filtered, and the cake washed with acetonitrile. The combined layers were evaporated. to dryness, and the residue (brown oil) subjected to flash column chromatography (hexane : EtOAc, 2:1). The product (white solid) was thus obtained in 40 - 55 ~ yield.
Thus were prepared: (R)-3-prop-2-ynylamino-5-indanol mesylate, (S)-3-prop-2-ynylamino-5-indanol mesylate, 1-prop-2-ynylamino-4-indanol HC1, and 3-prop-2-ynylamino-4-indanol HC1.

EXAMPLE 7: INHIBITION OF MAO ACTIVITY IN VITRO
EXPERIMENTAL PROTOCOL
The MAO enzyme source was a homogenate of rat brain in 0.3 M
sucrose 1:20 w/v. The homogenate was pre-incubated with serial dilutions of the test compounds (Table 5) for 60 minutes at 37°C. 19C-labeled substrates (2-phenylethylamine, hereinafter PEA; 5-hydroxytryptamine, hereinafter 5-HT) were then added, and the incubation continued for a further 20 minutes (PEA?, or 30-45 minutes (5-HT) . In the case of PEA, the enzyme concentration was chosen so that not more than 10~ of the substrate was metabolized during the course of the reaction. The reaction was then stopped by addition of citric acid. Radioactivity indicates the production of 5-HT and~PER metabolites formed as a result of MAO activity. Activity of MAO in the sample was expressed as a percentage of control activity in the absence of test compounds after subtraction of appropriate blank values.
The activity determined using PEA as substrate is referred to as MAO-B, and that determined using 5-HT as MAO-A.
