BAC~GROUND OF THE INVENTION

l. Field of the Invention This invention relates to substituted l-aryl-3-piperazin- l'-yl prop~nones and 1-arvl-3-piperidin-1'-yl propanones. These coll,pou.lds are useful in the l,~ t of Al7hr.imL~r's Disease, neopl~stic disease, and ba~t~ or fungal i~ cli 2. Description of the R~l~t~ Art 0 Al7hrimer's Disease is a progressive neurodegenerative disorder affecting 7% of the population over 65 years of age and characterized clinically by progressive loss of intel1~ctu~l function. This in,pai"l.ent of function is caused by the presence of neuri~ic plaques in the ne~co l~.~ and the loss of ~l~sy~la~Llc m~l~cl~~cholinergic neurons. Neuritic plaques are composed of degcn~ lg axons and nerve terrnin~lc~ often surrounding an amyloid core and I5 usually containing reactive glial elements. Another characteristic pathologic feature of ~l7heimer's Disease is the neurofibrillary tangle, which is an intraneuronal mass which C~ ,o,lds to an accum~ tiQn of abnormally phosphorylated tau protein polymerized into fibrillar structures termed paired helical hl~m~onrs In addition, the neurofibrillary ~angle also contains highly phosphorylated neurofii~mrnt proteins. Even the earliest papers on .A17~ 'S
20 Disease were clear that both "senile" plaques and neurofibrillary tangles had to be present in ablln-i~nr,e to allow a post-mortem diagnosis of the disease. Before any un~iersr:~n~i;ng of the molecular nature of these ~LIuClul~;S was obtained, efforts were being made to understand the relationship ~el~n the ~lulllb~ of these lesions and the progression or severity of the ~lemrrln~
expr ienre~ by the patient. The limit~ion.c of silver staining were such that early workers in this 25 field were unable to appreciate the complexity of these abnormal ~illU~;IulGs (Ball, MJ, Neurobiol.
of Aging, 8: 564-565, I987). Although early at~G,llpls to correlate pathologic lesion counts with clinical S~ (JIlls generally yielded poor results, it was clear that the inri~lenre of lar_e llulll~ls of both type lesions were invariably associated with ~iemen~ia (Perry et al. J. ~eural Transmission, 24: 131-136, 1987; Alafuzoff, I., Acta Neuropath, 74: 209-225, 1987;

SUBSTlTUtE SHEET (RULE 26) CA 0220~86 1997-0~-16 Wll;~ ho"se et al, Prog. Clin. Biol. Res., 317: 131-142, 1989; Tomlincon~ NeuloyaLllol. Appl.
Neurobiol, 15: 491-512, 1989).
More recent work has allowed a clearer clefinition of the nature of the lesions stained by silver salts. "Senile" plaques are actually two distinct types of ~Llu-;LulcS. the cl~ccic~l plaques S described by Al7heimçr being composed of degenerating neuronal elements (neurites) ~ulluundillg a central core of amyloid, while the other so-called "diffuse" or "pli~lliLivc" plaque is usually a deposit of amyloid without a halo of de~ ;,.g neurites (Tagliavini,, et al, Neurosci.
Lett., 93, 191-196, 1988; Dickson, DW, et al, Am. J. Path., 132, 86-101, 1988). These ~Llu~_lul~,s are liffie-llt to ~ictin~llich from each other with silver stains or with the widely used 10 nuor~,scc.,L dye, thioflavin S. Early attempts, using silver staining, at correlations bCL..~,.,ll plaque number and extent of ~1~ .. l ;~ as well as some more recent studies using thioflavin S, were flawed by this inability to define what type of plaque was being counted (Hansen, LA, et al, Neurology, 38, 48-54, 1988; ~t7.m~n, R, et al, Ann. Neurol., 23, 138-144, 1988). This bcco.l..,s very obvious in recent studies, which have corlcictently l~polL~d that amyloid plaques 15 can be found in large nu~ in the brains of the lllaJol;Ly of the very elderly (over 80 years), and are only rarely ~ccoci~ted with clem~nti~ when present without evidence of de~ul .a~il,g n~lritç5 (Davies, L, et al, Neurology, 38, 1688-1693, 1988; Delaere, P, et al, Nc~lusci. Lett., 116, 87-93, 1990; Dickson, DW, et al, Neurobiol. Aging, 13, 179-189, 1991).
The counting of neurofibrillary tangles also fails to give an ~cur~t~ picture of the extent 20 of neurofibrillary degeneration. Again, the presence of large numbers of tangles is invariably associated with a profound dçmtonti~, and some index of disease severity can be gained from tangle counts (Tomlinson, BE, Neul~palllol. Appl. Neurobiol., 15, 491-512, 1989; Delaere, P, et al, Acta Ne~l,u~atll., 77, 645-653, 1989). Electron mi~luscuy~ first revealed that tangles were cc.lll~osed of masses of paired helical fil~m~-,nt~ (PHF) filling the cytoplasm of neurons (Terry, 25 RD, et al, pages 145-155, In CIBA Fol-n~tion Symposium on ~ c;ll~'s Disease and Related Con-1ition~ Ed. by Wolstenholme, GEW, O'Conner, M, J and A Churchill, London, 1970).
These studies also clearly showed that degenerating neurites also co-,lai-,cd PHF, a fact only widely appreciated much later, when the use of antibodies to PHF became common (Wolozin, BL, et al, Sciçnre, 232, 648-650, 1986). Thus, both the plaques and the tangles of Al~ c 's SUBSTITUTE SHE-tT (RULE 26) Disease contain PHF. The use of antibodies to PHF also revealed the widespread presence of these paired helical fil~mentc in neuronal processes (Brun, A, Prog. Clin. Biol. Res., 317, 285-293, 1989~. Thus, the presence of PHF is much more widespread than was first s~lcpecte,l and is today concidered to be an infliratinn of a widespread neuronal disease, of which the neuritic 5 plaque and the neurr~fibrill~ry tangle are only the most obvious signs (McKee, AC, et al, Ann.
Neurol., 30, 156-165, 1991). It has been ectim~ted that as much ~s 90% of the PHF in the cortex of the average ~l,l.e~ . case is present in neuronal ~ ce,sses r~ther than in the plaque or tangle (Wolozin, BL, Ann. Neurol., 22, 521-526, 1987). Much of the early and indeed the present confusion with regard to ~ gnosic and severity of ~17~ f ~ 'S Disease comes from the 10 failure to a~l, ciale the complexity of the pathology in this disease. ~Ithough the oc~ tnce of si~ni~r~nt ~ 0~ of PHF in the brain is always ~cso~ tr~ with severe Citl,.f -,l;~ (Hyman, BT, Current Opinions in Neurology and Neurosurgery, S, 88-93, 1992). These results suggest that good coll~laLions can be obtailled bcL~ I the conce ~ JII of PHF proteins (COIllf.l;ll~f S referred to as ,A~ e;--~"'S Disease ~ccoci~d Proteins or ADAP) in the cerebr31 cortex and the degree of 5 tl~ n~;~ measured prior to the death of the patient (Gh~nb~ i, HA~ et al, JAMA, 263, 2907-2910, 1990).
It is noted that the terminology used to describe the abnormal protein complexescGIll~)osing the fibrillar pathology in Alzheimer's Disease can be confusing. PHF is a morphological Aecign~ti~n, describing abnormal fil~ment.c found in neurofihrill~ry tangles. An '~0 abnormal protein species migr~tinP at 68 kDa, elc~,llopho.cucally, and observed on immlmt blots of tissue from AD brains was termed A68 (Wolozin, B, et al, Science,232, 648-650, 1986). A
protein complex shown to be specific for AD by immnnochemical analyses was design~t~7 ~l~h~im~r~s Disease ~coci~le~l Protein or by the acronym, ADAP (Ghanbari, HA, et al, JAMA, 263, 2907-2910, 1990). It is now known that A68 and ADAP, when viewed by the electron r 2~ microscope, are PHFs. These PHFs have been further shown to contain, primarily, the microtubule-~ccoci~rt~(l protein, tau. Hence, the terms A68, ADAP, PHF and PHF-tau are often used int~l~h~l-ge~hly. Thus, they are meant to be interch~n~l~ herein.
A series of important studies have suggested that the progression of ~l7h~im~r's Disease can be defined pathologically by careful n~ulu~n~lo~ studies of large nU~11~1S of brains from SUBSTITUTE SHEET (RlJLE 26) WO 96/160~2 PCT/US95114987 elderly hl1m~ns, (Braak, H, et al, Neurosci. Lett., 103, 24-28, 1989; Braak, H, et al, Ntulu~alh. and Applied Neurobiol., lS, 13-26, 1989; Braak, H, et al, Acta Nc.llupdlll., 82, 239-259, 1991; Braak, H, et al, European Neurology, 33, 403-408, 1993). The Braak's focus is almost entirely on the dc~, elu~ ,l of neurofihnll~ry pathology, which begins in the ~ ,. h; . .~l S cortex perhaps years before the clinical signs of the disease are app~cnt. The progression of A~ F ;~ 'S Disease is thought to be soll~ l,at unllc~ , in the sense that the disease ~ ,a3eS
by the involvement of more and more neurons in the formation of PHF, in an ~n~tomic sequence which is to some extent pre~iirt~hl~. In the initial stages, only those neurons of the ~ \lo,~
cortex contain PHF, in latçr stages, neurons of the CA1 and CA2 pyramidal layer of the 10 hippocampus contain these StluCLul~,S, and still later, neurons of the ~ccoci~tinn cortex begin to show evidence of PHF forrnation. Clearly, pl~,.lLion of PHF formation even after the process is underway in the hippocampus could limit the disease to this brain region, at which point clinical problems are co, r; r~ to some loss of short terrn Ill~.llul y. Patients first seek help at a stage when PHF pathology is largely limited to the l~i~oc~ll~us (Berg, L, et al, pages 9-25, in 15 Al,l.~ 's Disease, Eds., Terry, RD; K~r7rn~n, R; Bick, Kl. Raven Press, New York, 1994).
To prevent the pr~ ion of ~l7l.. ~ 's Disease at this point would clearly be a major benefit to the patient (Davies, P, pages 327-334, in Al,l.- ;...- 's Disease, Eds., Terry, RD; ~t7m~n, R;
Bick, KL. Raven Press, New York, 1994; Kh~rh~tllri~n ZS, et al, pages 445-454, in ,,'s Disease, Eds., Terry, RD: K~t7m~n, R; Bick, KL. Raven Press, New York, 1994).
Attempts to cl~lr-.,.. ;n~ the mol~ocul~r nature of the PHF were h~~ lc;d at first by an approach which attempted to purify PHF from isolated neurofibrillary tangles. Once h~cc,l~ulaL~d into the llla ;lulllolecular CO~1CA that is the tangle, PHFs become eAI-~.llely difficult to soll-bili7.o for protein analysis. The microtubule-acsoci~t~ protein tau appears to be a major ~nri~eniC c~ n~llt of PHF. The repeat region of microtubule-~c~oci~ 1 protein tau forms part 25 of the core of the paired helical fil~m~nt of ~I,l.. ;...-, 's Disease (Goedert, M, et al, Proc. Nat'l.
Acad. Sci., 8S, 4051-4055, 1988; Wischik, CM, et al, Proc. Nat'l. Acad. Sci., 85, 4506-4510, 1988).
The involvement of prolein phosphorylation in the fr)rm~tion of PHF has been su~esteA
by a variety of studies which have shown that tau in PHF is hy~ hf ~l~hs~ ylated (Kosik, KS, et SUBSTITUTE SHEET (RULE 26) WO 96116052 PCT/US95tl4987 al, Ann. Med., 21, 109-112, 1989; Goedert, M, Trends in Neuroscienres~ 16, 460-465, 1993;
Iqbal, K, et al, Act Neurobiologiae E~ t,.li!c~ 53, 325-335, 1993). There is su~ h,~, evidence that several other ~rolcins, especi~lly neurofil~mrntc and other ll.icluL-~L ule ~soci~trd proteins (MAPs) are also hy~ ho ,~hr~ylat~d in the brains of patients with ~1,1.~ IIIF~- 's Disease .~ S (Lovestone, S, et al, Current Opinions in Neurology and ~ u:,ul~,.,,y, S, 883-888, 1992).
In 1985, a monoclonal antibody ALZ50 was raised (produced by hybridoma cell lineATCC No. HB9205) that recognized a 68 kDa polypeptide (termed A68) in imm--nnb1Ots of the vulnerable brain regions in AD, but not in control brains, (Wolozin, B, et al, Science,232, 648-650, 1986). T.. nohi~loc~ .. ;r~l analysis with this anti'oody in~'ir~.rçd an intense reaction with 10 neurofibrill~ry tangles and. in later cA~ illJ~nls, with the PHF's, as well. The discovery of A68 was the first report of a bioçhrmically ~ ...i.,e~ abnormal protein species ~ccoci~t~fl with the fibrillar pathology in AD.
In o~her iaboratories in 198~5, monoc~onal and polyclonal antibodies recognizing the microtubule-associated protein, tau, were shown to react with neurofibrillary tangles, and 15 subsequently, with PHFs (Grundke-Iqbal, I, et al, Proc. Nat'l,. Acad. Sci., 83, 4913-4917, 1986; Kosik, KS, et al, Proc. Nat'l. Acad. Sci., 83, 4044-4048, 1986). Furthermore, biocl....,;~l analyses of the ~lutGase-resistant "core" of the PHF d~ oll~L,attd the ~lesencG of peptides cont~ining the tau selluence, (Goedert, M, et al, Proc. Nat'l. Acad. Sci., 85, 4051-4055, 1988; Wischik, CM, et al. Proc. Nat'l. Acad. Sci., 85, 4506-4510, 1988). ~cldition~lly~
20 monoclonal antibodies, whose epiLol,eS sp~nnr-l the tau molecule, all were shown to react with neurofibrillary tangles in AD brain (Kosik, KS, et al, Neuron, 1, 817-825, 1988). Much later, it was ~letermin~l that the ALZ50 antibody reacts with the e~ cllle amino terrninus of the tau mrJlecllle (Goedert, M, et al, Neurosciçnr,e Letters, 126, 149-154, 1991).
In 1990, in an attempt to purify A68, a more readily soluble ~ Ou~lion of PHFs was 25 isolated (Greenberg, S and Davies, P, Proc. Nat'l. Acad. Sci., 87, 5827-5831, I990).
Tmml~nnblots of these ~,~uclulcs in~ir~tçd that three closely migrating cleclluyhulclic species, the slowest migrating of which was ca. 68 kDa in size, all reacted with ALZ50 and tau antibodies (Lee, V, et al, Science, 251, 675-678, 1991). This in~ic~tç~l that the A68 complex of proteins SUBSTITUTE Sl IEET (RULE 26) WO 96~16052 PCT/US95/14987 is, to a large extent, coll.yo3ed of the tau protein. This polymerized form of tau was shown over the years to be in a hyy~hn~l~horylated state.
Other monoçlon~l antibodies raised against human PHF l,l~aldlions are the antibodies PHF-1 and TG3. While these antibodies display robust affinity for paired helical fil~m~-5 ~ alalions~ they only have trace l-,aclivily towards normal adult tau. Further studies revealed that the mo~oclon~l antibody PHF-1 has a reduced affinity for PHF which has been treated with alkaline phosphatase or hy~LunLIulic acid, thereby suggesting that this antibodv recognized a ph~spl.o.ylat.,d epitope(s) in paired helical fil~m~n-c These pho~yllolylated ~,piluyCS (recogniæd by PHF-1) reside within the C-tçrTnin~l fragment of the tau protein, at serine 396 and 404 10 (Trojanowski, J.Q., et al, Clin. Neurosci., 1, 184-191, 1993). The epitope(s) l~cûg-li~cd by TG3 has not been mapped yet.
To date, it has not been possible to c ?ncictently induce the fo~nation of ~l71,f ;."f -like e~iluyes either in vivo or in vitro. Hence~ there is a need for an assay for the ric~r , l l;l~ on of tau protein, paired helical fil~mf ntc and ..,fcl-~-;cmc involved with ~17hçimf r's Disease. There is 15 further a need for an assay suitable for S~ ling for drugs which may prevent or decrease Al,l.~ . 's Disease activity.

SUBSTITUTE SHEET (RULE 26) SUMMARY OF THE INVENTION
The co~ -ds of this invention and an al,Lil yscl~otic agent, chlo~ r are active in an assay indicative of the potential of certain drugs to inhibit a h:~llm~rk trait of ~ 's Disease. Further, chlol~ e is shown herein to be capable of treating and/or preventing 5 ~l7hçim~r~s Disease. Const.lu~ iy~ the compounds of this invention are useful for treating and/or ~.c~".Lillg the disease.
The human neurobl~ctom~ MSNla cell line G~ 5CS the plvt~;ns known to be involvedin PHF formation (inclllfling tau, other MAPs and neurofil~mf nt plc,Le;~,s, and thus is a cell line in which ~l7llf ;...l 's Disease e~iLo~e,s can be G~ ,ssGd. (Arias et al, J. Ne.,-~he,ll., 61: 673-10 682, 1993; Vincent et al, J. Nc.~ ., 62: 715-723, 1994).
Immunohistochemi~ ~l st~inin~ of brains from normal and Alzheimer's Disease (AD)patients using the monoclonal antibodies PHF-1 and TG3 inrii~pr~s that these monoclonal antibodies specificallv stain c~ of AD brain, but not normal brain (hgure 1). C`onrlitions were est~klich~od which led to hyperphosphorylation of the proteins known to be involved in 15 PHF formation. Using monoclonal antibodies PHF-1 and TG3 generated to human PHF
aldtions, the effects of a variety of manipulations of the pho5phorylation state of these proteins were tested. These tests c~luilcd that most of the aLncl ,lldl c~ilo~es l~,co~ cd by these monoclonal antibodies in the human ~l7h~imer brain should be gcll~ tcd in the MSNla cells.
The llc~ nr of MSNla cells with okadaic acid and other selecte~ inhibitors of protein 20 phosphatases has been found to generate the epitopes associated with these ~l~h~im~:r brain specifi. monoslona! antibodies, thereby meeti;.g, the re4ui~cil.c.its described above. These e~i~s are either absent or present at a very low level in ~Illllc~Lt~d MSNla cells.
The AD specifi~ity of the PHF-l and TG3 ~ntiho~ s was also demonstrated using anELISA assay. Shown in Figure 2A are bar graphs (percent of AD) of the ELISA
25 immllnoreactivity of brain plc~dlions (AD or normal) to either PHF-1 or TG3. Shown in Figure 2B are bar graphs (percent of MSN+) of the ELISA immnnoreactivity of MSNla cell Jaldlions (minus or plus okadaic acid) to either PHF- 1 or TG3. The MSNla cell ~ ~dlions plus vs minus okadaic acid closely parallel the AD vs normal brain l,lep~ ;o~c This clearly shows the relationship belv~ecn disease pathology (i.e. AD brain) and what is recognized by the SUBSTITUTE SHEET (RULE 26) CA 0220~x6 1997-0~-16 WO 96116052 PcrluS95/14987 antibodies in the MSNla in vilro cell culture assay. The cell culture system according to the LiOIl in which ~.p;~f,S C~ af`~ tiC of PHF can be readily ge~ tf -i and sul: s~ y l~eeo~ i by the specific ~1~1.. ;,.... brain specifie antibodies provides an assay suitable for screening cu~ oullds for their ability to block the ~luJI~ l;ol. of these pi~osL.hfj ylated c~itupcs.
PHF tau protein has lower affinity for microtubules as colllpdlcid to normal tau protein, which is likely the result of the abnf)rm~l pho~ .ulylatiûn (Lindwall et al, J. Biol. Chem., 259:
5301-5305, 1984). As a co..se~l~le..ce, microtubule ~lest~kili7~tion occurs which i~telr~..,s with illll,c,lia.ll neuronal ~lucesses such as rapid axonal Llansl,uli and, subsequently, this process leads to the follllaLiol. of PHF and the neurofibrillary tangles (Bancher, et al, Brain Res., 477, 10 90-99, 1989). Thus, inhibition of the ~ iul,l;on of the abnorrnal phosphorylated PHF f~)iL~)e S
will i~ .r~.e with and/or prevent the fO..l-atioll of PHF. Since PHF formation is a major feature of 1~ f l pathology, the development of co~ ol"~ds that intu.rcl~ with all or part of this process inhibit or prevent the ~lu~ ion of this disease.
The invention provides co-l-yuul-ds of formula I:

The colll~ullds of forrnula I inhibit and/or prevent the formation of abnornallyphosphorylated epi~opes on PHF tau. Through inhibitory il~L~ ~acLions of the phosphorvlation events associated with the forrnation of PHF tau and other proteins involved in PHF ~",~I;Ol"
one can rno~ te the ~çmhly of tnicrotubules, thereby affecting neuronal processes such as rapid axonal transport, thus preventing the forrnation of PHF and the production of the 15 neurofih ill~ry tangles. Thus, the co",~ou,~ds of the present invention are lhc. .~ 11y useful in various neurodeg.--.~ aLive disorders such as ~ ;".t~ s Disease.

Phosphorylated sites on the PHFs found in 10 neurofibrill~ry tangles and abnormal neurites are detected by AD-specific antibodies, such as TG3 and PHF-1, in the brains of AD pati~ntc and not in normal or other neuro~eg,~ e disease controls (cf. Figure 1, 2A). In the MSNla cell culture model (cf. Figure 2B, 3), these ly phosphorylated PHF sites are also rlet~cted by these ~ntihodies Th~.~r...~, the Ih~a~ lic activitv of the co~ c of the invention was ~csecsed by the 15 ability of these agents to affect the ~-u.lu~,Lion of abr-orm~lly phosphorvlated c~ u~ues p~Li~ to the production of PHFs of AD, utili7ing a human neuroblastoma cell line (MSNla) in the presence of the protein phosphatase inhibitor, okadaic acid (OKA). As described above, chlo~ olllazine, a clinically used antipyschotic, prevents production of the aberrantly phosphorylated PHF c~ ûl)es and, hence, the production of PHFs, thereby preventing AD. As 20 shown in Figures 2B and 3, and in Table 2, chlc,ll,lu.,,~7ine is effective in inhibiting the production of these aberrant phosphorylated epitopes in the MSNla cell culture model as det~ h~cd by the prevention of the imm~lnoreactivity ~ccoci~no~l with PHF antibodies such as TG3 which was utilized in the l~o~ ;Live clinical analysis.
