     FIELD OF INVENTION 
     The present invention is a class of oximes and amines which are muscarinic agonists, rendering them useful as pharmaceutical agents. More specifically, the compounds are azabicyclic and azacyclic oximes and amines. 
     BACKGROUND 
     Disorders of cognition are generally characterized by symptoms of forgetfulness, confusion, memory loss, attentional deficits, and/or, in some cases, affective disturbances. These symptoms may arise as a result of the general aging process and/or from organic brain disease, cerebrovascular disease, head injury, or developmental or genetic defects. 
     The general decrease in cognitive function which accompanies the aging process is well accepted. The same phenomenon has been observed and documented in many lower mammals, including those routinely employed in pharmacological testing programs for screening and predicting usefulness for particular drugs in higher animals, including humans. 
     Although disorders of cognition often accompany the general aging process, presenile and senile primary degenerative dementia are the most common accepted causes of mental deterioration in the elderly. It has been estimated that at least 10 percent of persons over 60 years of age will eventually suffer severe mental deterioration. A much larger number will experience cognitive decline of sufficient severity to impede their activities. 
     Many of the symptoms of cognitive disorders, especially impaired memory, are associated with decreased acetylcholine synthesis and the impairment of cholinoreceptive neurons. In the hippocampus and cerebral cortex of patients suffering from primary degenerative dementia, for example, the level of the enzyme choline acetyltransferase (CAT) can be reduced by as much as 90% (see Davies, et al., The Lancet 1976;2:1403; Perry, et al., J. Neurol, Sci. 1977;34:247-265; and White, et al., The Lancet 1977;1:668-670). 
     Since CAT catalyzes the synthesis of acetylcholine from its precursors choline and acetyl coenzyme A, the loss of CAT reflects the loss of cholinergic, or acetylcholine-releasing, nerve endings in the hippocampus and cerebral cortex. There is abundant evidence that cholinergic terminals in the hippocampus are critically important for memory formation. 
     The cholinergic hypothesis suggests that drugs which restore acetylcholine levels or which mimic the action of acetylcholine (i.e., are cholinomimetic) are effective in correcting this deficit in neurotransmitter chemical and provide treatment of the memory impairment symptom of cerebral insufficiency. Considerable biochemical, pharmacological, and electrophysiological evidence supports the hypothesis that deficits in the cholinergic system underlie geriatric cognitive dysfunction (see Peterson C., Gibson G. E., Neurobiol. Aging 1983;4:25-30). Aged humans and nonhuman primates with decreased cognition show improved memory when they are treated, for example, with acetylcholinesterase inhibitors such as physostigimine. These agents increase the available supply of synaptic acetylcholine by inhibiting its hydrolysis. 
     Aminopyridines such as 3,4-diaminopyridine ameliorate age-related cognitive deficits by increasing the release of acetylcholine from presynaptic nerve terminals, thus increasing synaptic acetylcholine (see Davis H.P., et al., Exp. Aging Res. 1983;9:211-214). 
     It has been known for some time that the natural alkaloid, muscarine, has the ability to act relatively selectively at autonomic effector cells to produce qualitatively the same effects as acetylcholine. Two alkaloids, pilocarpine and arecoline (the methyl ester of 1,2,5,6-tetrahydro-1-methyl-3-pyridinecarboxylic acid), have the same principal sites of action as muscarine and acetylcholine and are thus classified as having &#34;muscarinic&#34; action. Although these naturally occurring alkaloids are of great value as pharmacological tools, present clinical use is largely restricted to the use of pilocarpine as a miotic agent. 
     Recently it has been demonstrated that arecoline is effective in ameliorating some of the symptoms of cognitive disorders in patients clinically diagnosed as having presenile primary degenerative dementia. Significant improvement was observed in a test of picture recognition after administration of arecoline to patients in a double-blind study (see Christie, et al., Brit. J. Psychiatry 1981;138:46-50). 
     The use of cholinomimetic agents in multiple clinical trials has documented both the potential therapeutic utility of cholinergic agents and the high incidence of unwanted side effects (see Hollander E., et al., Brit. Med. Bull. 1986;42:97-100). Many of these unwanted side effects result from the nonselective stimulation of cholinergic receptors (of the muscarinic type) located throughout the body. Muscarinic receptors have been classified pharmacologically and at the molecular level into several subtypes (see Bonner T., Trends Pharmacol, Sci. 1989;(Suppl. on Subtypes of Muscarinic Receptors IV):11-15). The receptors responsible for the central cognition-enhancing effects of muscarinic cholinomimetic agents are generally defined as M 1  (pharmacological definition) or ml (molecular definition). Activation of peripheral M 2  and M 3  (or m2 and m3) receptors is thought to be responsible for the unwanted side effects of the currently available muscarinic agents (e.g., sweating, diarrhea, cramps, excessive salivation, etc). Thus, selective M 1  (or ml) muscarinic agonists hold the best promise for selective improvement of cognitive function without the occurrence of unwanted side effects.

In yet another aspect, the present invention provides a method of treating the symptoms of senile cognitive decline in the elderly characterized by decreased cerebral acetylcholine production or release comprising administering to a patient in need of such treatment of cholinergically effective amount of a compound as defined above in combination with a pharmaceutically acceptable carrier. 
     The compounds of the present invention may exist in either of two Z and E isomeric and enantiomeric forms. The present invention includes both forms of the compounds as well as mixtures of the Z and E forms. Illustratively Formulas Va and Vb depict the Z and E forms of the compounds of Formula I. Moreover, in those compounds in which there is a double bond in a carbon chain, both the Z and E forms of the olefins are included in the present invention. ##STR16## 
     The compounds of Formulas I, III, and IV are prepared by reacting a ketone of the following Formulas XII, XIII, and XIV with an amine of the formula NH 2  OR.HCl wherein R and R 3  have the meanings defined in Formulas I, II, III, and IV as depicted below: ##STR17## 
     In each of the above depicted reactions, typically methanol is used as the solvent and the reaction is carried out at room temperature. 
     The compounds of Formula II are prepared by reducing Formula I compounds by procedures well known in the art, for example, by treatment with sodium cyanoborohydride under controlled pH conditions. Therefore, not only are the compounds of Formula I pharmaceutically useful they are also useful as starting material to make pharmaceutically useful compounds. Similarly, the compounds of Formula I wherein R is hydrogen may be used to prepare compounds of Formula I wherein R is the group --C(═O)R 6 , The compounds of Formula V are prepared by reacting a ketone of the following Formula XV with a hydroxylamine (as the free base or salt) of the formula NH 2  OR wherein R has the meanings defined in Formula I as depicted below: ##STR18## 
     In the above depicted reaction, typically methanol is used as the solvent and the reaction is carried out at room temperature. 
     As discussed above, the compounds of Formulas I and V are prepared by reacting a ketone of the Formulas XII and XV, respectively, with hydroxylamine or an O-substituted hydroxylamine. Preferably, the ketones of Formulas XII and XV are prepared in accordance with Chart II provided herein wherein R 3  and n are as defined above. 
     As illustrated in Chart II, a protecting group is placed on the nitrogen of a dihydroxy-substituted piperidine (1a). The protecting group my be any of those known to those of skill in the art. Preferably, the protecting group is a carbamate or a benzyl group. The primary alcohol of the protected dihydroxysubstituted piperidine (2a) is then activated by the addition of tosyl chloride at about 0° C. 
     The resulting tosylated piperidine (3a) is then cyclized and the protecting group removed (alternatively, the protecting group can be removed and the (3a) cyclized). This step can involve using hydrogen and a 20% palladium on carbon catalyst in ethanol and heating; nevertheless, other procedures known to those of skill in the art which convert piperidine (3a) to intermediate (4a) can be employed. The resulting intermediate (4a) is obtained in racemic form. 
     The intermediate (4a) may be oxidized into the ketone of Formulas XII or XV (5a) i.e., by the Swern reaction, the resulting ketone (5a) being obtained in racemate form. Alternatively, the intermediate (4a) may be resolved into the 4R and 4S enantiomeric forms by the addition of tartaric acid or the like. Oxidation of the enantiomers results in enantiomeric ketones of Formulas XII and XIV (6a). 
     The salts of the final products are prepared by contacting the free base form of the compounds of this invention with a sufficient amount of the desired acid to produce the salt in the conventional manner. The free base forms may be regenerated, if desired, by treating the salt form with a base. For example, dilute aqueous solutions of such bases as sodium hydroxide, potassium carbonate, ammonia, and sodium bicarbonate maybe utilized for this purpose. 
     The free base forms of the compounds of this invention differ somewhat from their respective salt forms in such physical properties as melting point and solubility in polar solvents, but the salts are otherwise equivalent to their respective free acid or base forms for the purposes of the invention. 
     The starting materials represented by Formulas XII, XIII, XIV, and XV are known in the art or can be prepared by procedures generally known in the art (see, for example, Saunders J, et al., J. Chem, Soc., Chem. Comm. 1988:1618 and Snow R. J., Street L. J., Tet. Lett. 1989;30:5795). Also, the hydroxylamines represented by NR 2  OR are commercially available or may be prepared by procedures generally known in the art. For example, the amines or hydroxylaxnines can be prepared by reacting an N-hydroxyphthalimide with an appropriate alcohol and hydrolyzing the resultant intermediate using methylhydrazine. Similarly, the N-hydroxyphthalimide can be reacted with an appropriate aliphatic or alicyclic bromide. The examples and preparations set forth below illustrate the synthesis of the compound of this invention.

     General Procedure for the Preparation of Oximes of Formula V 
     1-Azabicyclo[2.2.1]heptan-3-one was prepared according to J. Chem. Soc., Chem. Comm. 1988:1618. 
     A solution of 1-azabicyclo[2.2.1]heptan-3-one (2 g, 18 mmol) and the substituted hydroxylamine (hydrochloride salt) (H 2  NOR-HCl; 18 mmol) in 10 mL methanol is stirred at room temperature for 18 hours. The reaction mixture is concentrated in vacuo. The residue is partitioned between CH 2  Cl 2  and saturated potassium carbonate. The organic phase is dried over anhydrous sodium sulfate and evaporated in vacuo. The residue is converted to its oxalate salt and recrystallized from ethanol to afford the desired oxime as a mixture of E and Z oximes. The two geometric isomers can be separated by column chromatography on silica gel (CH 2  Cl 2  :MeOH; 9:1). Using this procedure with the appropriate chiral ketone, the following compounds were prepared as the oxalate salts:

     The compounds of the present invention are centrally acting muscarinic agents and are thus useful as analgesic agents for the treatment of pain in mammals including man, as sleep aids, and as agents for treating the symptoms of senile dementia, Alzheimer&#39;s disease, Huntington&#39;s chorea, tardive dyskinesia, hyperkinesia, mania, or similar conditions of cerebral insufficiency characterized by decreased cerebral acetylcholine production or release. 
     The biological activity of compounds of the present invention was evaluated using a number of tests. The activity of compounds of this invention as central muscarinic binding site agonists and antagonists was measured. In the RQNB screening assay, which is described more fully by Mark Watson, et al. J. Pharmacol. Exp. Ther. 1986;237(2):411, rat cerebral cortex tissue was treated with radiolabeled quinuclidinyl benzilate, a known muscarinic antagonist. The concentrations of test compound required to inhibit 50% of the binding of this muscarinic antagonist were then determined. 
     Similarly, in the RCMD screening assay, described more fully by Vickroy T. W., et al., 1984;229(3):747, rat cerebral cortex tissue was treated with radiolabeled cis-methyldioxolane, a known muscarinic agonist. The concentrations of test compounds required to inhibit of the binding of this muscarinic agonist were then determined. These values are reported as IC 50  concentrations in Table 4 and demonstrate that the compounds of the present invention possess significant muscarinic activity.

     In therapeutic use as agents for treating pain or for treating cerebral insufficiency, the compounds utilized in the pharmaceutical method of this invention are administered to the patient at dosage levels of from 0.07 to 700 mg per day. For a normal human adult of approximately 70 kg of body weight, this translates into a dosage of from 0.01 to 100 mg/kg of body weight per day. The specific dosages employed, however, may be varied depending upon the requirements of the patient, the severity of the condition being treated, and the activity of the compound being employed. The per day. The specific dosages employed, however, may be varied depending upon the requirements of the patient, the severity of the condition being treated, and the activity of the compound being employed. The determination of optimum dosages for a particular situation is within the skill of the art. 
     For preparing pharmaceutical compositions from the compounds of this invention, inert, pharmaceutically acceptable carriers can be either solid or liquid. Solid form preparations include powders, tablets, dispersible granules, capsules, cachets, and suppositories. 
     A solid carrier can be one or more substances which may also act is diluents, flavoring agents, solubilizers, lubricants, suspending agents, binders, or tablet disintegrating agents; it can also be an encapsulating material. 
     In powders, the carrier is a finely divided solid which is in a mixture with the finely divided active component. In tablets, the active compound is mixed with the carrier having the necessary binding properties in suitable proportions and compacted in the shape and size desired. 
     For preparing suppositories, a low-melting wax such as a mixture of fatty acid glycerides and cocoa butter is first melted, and the active ingredient is dispersed therein by, for example, stirring. The molten homogeneous mixture is then poured into convenient sized molds and allowed to cool and solidify. 
     Powders and tablets preferably contain between about 5% to about 70% by weight of the active ingredient. Suitable carriers are magnesium carbonate, magnesium stearate, talc, lactose, sugar, pectin, dextrin, starch, tragacanth, methyl cellulose, sodium carboxymethyl cellulose, a low-melting wax, cocoa butter, and the like. 
     The term &#34;preparation&#34; is intended to include the formulation of the active compound with encapsulating material as a carrier providing a capsule in which the active component (with or without other carriers) is surrounded by a carrier, which is thus in association with it. In a similar manner, cachets are also included. 
     Tablets, powders, cachets, and capsules can be used as solid dosage forms suitable for oral administration. 
     Liquid form preparations include solutions suitable for oral or parenteral administration, or suspensions, and emulsions suitable for oral administration. Sterile water solutions of the active component or sterile solutions of the active component in solvents comprising water, ethanol, or propylene glycol may be mentioned as examples of liquid preparations suitable for parenteral administration. 
     Sterile solutions may be prepared by dissolving the active component in the desired solvent system, and then passing the resulting solution through a membrane filter to sterilize it or, alternatively, by dissolving the sterile compound in a previously sterilized solvent under sterile conditions. 
     Aqueous solutions for oral administration can be prepared by dissolving the active compound in water and adding suitable flavorants, coloring agents, stabilizers, and thickening agents as desired. Aqueous suspensions for oral use can be made by dispersing the finely divided active component in water together with a viscous material such as natural or synthetic gums, resins, methyl cellulose, sodium carboxymethyl cellulose, and other suspending agents known to the pharmaceutical formulation art. 
     Preferably, the pharmaceutical preparation is in unit dosage form. In such form, the preparation is divided into unit doses containing appropriate quantities of the active component. The unit dosage form can a packaged preparation, the package containing discrete quantities of the preparation, for example, packeted tablets, capsules, and powders in vials or ampoules. The unit dosage form can also be capsule, cachet, or tablet itself, or it can be the appropriate number of any of these packaged forms. ##STR83##
