Description: PHARMACEUTICALLY ACTIVE COMPOUNDS AND METHODS OF USE This application is a continuation-in-part of copending U.S. application serial number 08/601 ,992, filed February 15, 1996, which application is incorporated herein by reference. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to pharmaceuticially active compounds, including certain substituted indolinyl (and derivatives thereof), 1,2,3,4-tetrahydroquinolinyl (and derivatives thereof), 1,2,3,4-tetrahydroisoquinolinyl, benz[cd] indolinyl and 5,6- dihydrophenanthridinyl compounds, and methods of treatment and pharmaceutical compositions that utilize or comprise one or more such compounds. Compounds of the invention are particularly useful for the treatment or prophylaxis of neurological injury and neurodegenerative disorders. 2. Background Nerve cell death (degeneration) can cause potentially devastating and irreversible effects for an individual and may occur e.g. as a result of stroke, heart attack or other brain or spinal chord ischemia or trauma. Additionally, neurodegenerative disorders involve nerve cell death (degeneration) such as Alzheimer's disease, Parkinson's disease, Huntington's disease, Amyotrophic Lateral Sclerosis, Down's Syndrome and Korsakoff s disease. Therapies have been investigated to treat nerve cell degeneration and related disorders, e.g. , by limiting the extent of nerve cell death that may otherwise occur to an individual. See, e.g., N. L. Reddy et al., J. Med. Chem. , 37:260-267 (1994); and WO 95/20950. The compound MK-801 has exhibited good results in a variety of in vivo models of stroke. See B. Meldrum, Cerbrovascular Brain Metab. Rev. , 2:27-57 (1990); D. Choi, Cerbrovascular Brain Metab. Rev. , 2: 105-147 (1990). See also Merck Index, monograph 3392, 11th ed., 1989. For example, MK-801 exhibits good activity in mouse audiogenic tests, a recognized model for evaluation of neuroprotective drugs. See, e.g., M. Tricklebank et al., European Journal of Pharmacology, 167: 127-135 (1989); T. Seyfried, Federation Proceedings, 38(10):2399-2404 (1979). However, MK-801 also has shown toxicity and further clinical development of the compound is currently uncertain. See J. W. Olney et al., Science, 244: 1360-1362 (1989); W. Koek et al., J. Pharmacol. Exp. Ther. , 252:349-357 (1990); F.R. Sharp et al. , Society for Neuroscience Abstr. , abstr. no. 482.3 (1992). It thus would be highly desirable to have new neuroprotective agents, particularly agents to limit the extent or otherwise treat nerve cell death (degeneration) such as may occur with stroke, heart attack or brain or spinal cord trauma, or to treat neurodegenerative disorders such as Alzheimer's disease, Parkinson's disease, Huntington's disease, Amyotrophic Lateral Sclerosis, Down's Syndrome and Korsakoffs disease.

Compounds of the invention can be prepared by the reaction of a suitable precursor compound, e.g. indolinyl (or derivative thereof) compound, 1,2,3,4- tetrahydroquinolinyl (or derivative thereof) compound, 1,2,3,4-tetrahydroisoquinolinyl compound, benz[cd] indolinyl compound, 5,6-dihydrophenanthridinyl compound, 2,3,4,5-tetrahydro-[l,5]-benzothiazepine compounds (or derviative thereof, e.g. where X is other atom), 2a,3,4,5-tetrabenz[cd]indoline compound, 5,6,11,12- tetrahydrodiben[b,fjazocine compound, etc. (depending on whether a compound of Formulae I, I", II, II", III, IV, V, VI, VII, VIII or IX respectively, is being prepared) with a preformed alkyl or aryl cyanamide (see S.R. Safer, et al., J. Org. Chem. , 13:924 (1948)) or the corresponding N-substituted alkyl or aryl cyanamide. Typically, a salt of the amine (e.g. an HCI salt) is reacted with the cyanamide. More particularly, compounds the invention can be suitably prepared by reaction of an appropriate indolinyl (or derivative thereof) salt (to prepare compounds of Formulae I, I', I", la, Iaa or lb), 1,2,3, 4-tetrahydroquinolinyl (or derivative thereof) salt (to prepare compounds of Formulae H, II", Ila, Ilaa or lib), 1,2,3,4- tetrahydroisoquinolinyl salt (to prepare compounds of Formulae HI, Ilia, πiaa or iπb), benz[cd]indolinyl salt (to prepare compounds of Formulae IV, IVa, IVaa or IVb), or 5,6-dmydrophenanthridinyl salt (to prepare compounds of Formulae V, Va, Vaa or Vb) or other appropriate salt such as salts of above mentioned precursor compounds (to form compounds of Formulae VI-IX) with a substituted cyanamide in a suitable solvent such as toluene, chlorobenzene or the like under an inert atmosphere such as argon or nitrogen as exemplified in the Scheme below. The reaction solution is then heated e.g. from about 110° to 120°C for 2 to about 16 hours until reaction completion, e.g. as indicated by thin layer chromatography. The reaction solution is then cooled to room temperature, and the solvent is then removed under reduced pressure to provide the desired compound of the invention. The crude product then can be purified by recrystallization and/or column chromatography, e.g. by elution one or more times on silica gel (e.g., 60-200 mesh, 50x w/w) with suitable solvents. See Example 2 which follows for exemplary conditions. The indolinyl (or derivative thereof), 1,2,3,4-tetrahydroquinoline (or derivative thereof), 1,2,3,4-tetrahydroisoquinoline, benzfcd] indolinyl or 5,6- dihydrophenanthridinyl ot other presursor such as those mentioned above (for Formulae VI-IX) and cyanamide reagents with appropriate substiments are commercially available or can be readily prepared by known procedures. For example, the cyanamide starting material can be synthesized from the correspondingly substituted amine by treatment with cyanogen bromide (BrCN) in a suitable solvent such as dry ethyl ether or toluene at reduced temperatures (e.g. 0°C) or room temperature. As exemplified in the Scheme below, the amine to be reacted with cyanogen bromide is substimted with the R moiety as defined above for Formulae I, I" , II, II", HI, IV, V, VI, VII, VIII or IX (in the Scheme, that R moiety is exemplified as phenyi which may be ring-substituted by groups R, and R 2 ). Thus, various R groups of compounds of Formula I through IX (Which includes Formulae I" and II") can be provided by use of suitable substituted amines that are reacted with BrCN, such as e.g. substimted and unsubstimted anilines as shown in the Scheme, substimted and unsubstituted 1-naphmylamine, 2-naphthylamine, acenaphthylamine, etc. R 1 groups other than hydrogen of compounds of Formulae I through IX can be readily provided by reaction of a substituted cyanamide with a suitable nucleophile such as a halide reagent (e.g., a substituted or unsubstimted alkyl or alkenyl iodide or bromide). Thus, as exemplified in the Scheme below, the aryl cyanamide is reacted with NaH in a solvent of tetrahydrofuran and reacted with the iodide reagent R , such as substimted or unsubstituted methyl, ethyl, propyl, butyl, etc. iodide, an alkenyl iodide, etc. Also, compounds of the invention having an R 1 group of methyl can be prepared by reaction of a mono-substituted amine (e.g., an aniline, naphthylamine or acenaphthylamine) with formic acid followed by treatment with lithium aluminum hydride to provide the corresponding methyl- substimted cyanamide (e.g., C 6 H 5 N(CH 3 )CN from unsubstimted aniline). Alkylsulfinyl-substituted or alkylsulfonyl-substituted reagents, that can provide correspondingly substituted compounds of the invention as described above, can be provided by oxidation (e.g. , H 2 O 2 ) of alkylthio-substituted reagents. See for instance Example 46 which follows. While the Scheme depicts preparation of compounds of Formula I, the same procedures can be employed to prepare compounds of Formulae I', II, II", III, IV, V, VI, VII, VIII or IX by use of a 1,2, 3, 4- tetrahydroquinolinyl (or derivative thereof) salt, 1,2,3,4-tetrahydroisoquinolinyl salt, benz[cd]indolinyl salt or 5,6- dihydrophenanthridinyl salt or other corresponding salt for compounds of Formulae VI through IX, respectively, in place of the indolinyl salt shown in the Scheme. SCHE E Compounds of Formula II where R and R 1 are each hydrogen can be prepared by reaction of 1,2,3,4-tetrahydroquinoline compound with cyanamide. R 2 substiments can be provided by reaction of a substituted or unsubstituted quinoline compound with a Grignard reagent followed by hydrogenation to provide the substimted 1,2,3,4- tetrahydroquinoline compound. See Example 3 which follows for an exemplary procedure. See also Examples 41 and 42 which follow. Compounds of Formulae I", H" and VI where X is -S(O)- or -S(O) 2 - can be prepared by oxidation (e.g. with H 2 O 2 and/or with sodium periodate) of the corresponding preformed compounds where the ring member X is -S-. See for instance Example 47 which follows. The amine starting materials are commercially available and/or can be readily prepared. For example, benz[cd]indoline and 5,6-dihydrophenanthridine reagents can be prepared treatment of a benz[cd]indo-2(lH)-one compound or 5,6- dihydrophenanthridinone compound with a base such as diborane in a suitable solvent such as tetrahydrofuran. See Example 1 which follows for exemplary conditions. Chiral compounds of the invention may be used as optically enriched or racemic mixtures. An optically enriched mixture contains substantially more (e.g. about 60%, 70%, 80% or 90% or more) of one enantiomer or diastereoisomer than the other stereoisomers. Optically enriched mixtures can be obtained by known procedures, e.g. , column chromatography using an optically active binding material or formation of a salt using an optically active material, particularly an optically active acid. Particularly preferred optically enriched mixtures include sulfinyl-containing compound of the invention, e.g. compounds of Formulae I", II" or VI where X is -S(O)-, or compounds having having an alkylsulfinyl or other sulfinyl substiment. Such optically active mxtures of sulfmyl-containing compounds can be readily prepared, e.g. by column chromatography using an optically active binding material. As discussed above, the present invention includes methods for treating preventing certain neurological disorders, including the consequences of stroke, heart attack and traumatic head or brain injury, epilepsy or neurodegenerative diseases comprising the administration of an effective amount of one or more compounds of the invention to a subject including a mammal, particularly a human, in need of such treatment. In particular, the invention provides methods for treatment and/or prophylaxis of nerve cell death (degeneration) resulting e.g. from hypoxia, hypoglycemia, brain or spinal cord ischemia, brain or spinal cord trauma, stroke, heart attack or drowning. Typical candidates for treatment include e.g. heart attack, stroke and/ or persons suffering from cardiac arrest neurological deficits, brain or spinal cord injury patients, patients undergoing major surgery such as heart surgery where brain ischemia is a potential complication and patients such as divers suffering from decompression sickness due to gas emboli in the blood stream. Candidates for treatment also will include those patients undergoing a surgical procedure involving extra- corporal circulation such as e.g. a bypass procedure. The invention in particular provides methods for treatment which comprise administration of one or more compounds of the invention to a patient that is undergoing surgery or other procedure where brain or spinal cord ischemia is a potential risk. For example, carotid endarterectomy is a surgical procedure employed to correct atherosclerosis of the carotid arteries. Major risks associated with the procedure include intraoperative embolization and the danger of hypertension in the brain following increased cerebral blood flow, which may result in aneurism or hemorrhage. Thus, an effective amount of one or more compounds of the present invention could be administered pre-operatively or peri-operatively to reduce such risks associated with carotid endarterectomy, or other post-surgical neuorological deficits. The invention further includes methods for prophylaxis against neurological deficits resulting from e.g. coronary artery bypass graft surgery and aortic valve replacement surgery, or other procedure involving extra-corporal circulation. Those methods will comprise administering to a patient undergoing such surgical procedures an effective amount of one or more compounds of the invention, typically either pre- operatively or peri-operatively. The invention also provides methods for prophylaxis and treatment against neurological injury for patients undergoing myocardial infarction, a procedure that can result in ischemic insult to the patient. Such methods will comprise administering to a patient undergoing such surgical procedure an effective amount of one or more compounds of the invention, typically either pre-operatively or peri-operatively. Also provided are methods for treating or preventing neuropathic pain such as may experienced by cancer patients, persons having diabetes, amputees and other persons who may experience neuropathic pain. These methods for treatment comprise adirjinistration of an effective amount of one or more compounds of the invention to a patient in need of such treatment. The invention also provides methods for treatment and prophylaxis against retinal ischemia or degeneration and resulting visual loss. For example, a compound of the invention can be administered parenterally or by other procedure as described herein to a subject a suffering from or susceptible to ischemic insult that may adversely affect retinal function, e.g. , significantly elevated intraocular pressures, diseases such as retinal artery or vein occlusion, diabetes or other ischemic ocular- related diseases. Post- ischemic administration also may limit retinal damage. The invention also includes methods for treating and prophylaxis against decreased blood flow or nutrient supply to retinal tissue or optic nerve, or treatment or prophylaxis against retinal trauma or optic nerve injury. Subjects for treatment according to such therapeutic methods of the invention may be suffering or susceptible to retinal ischemia that is associated with atherosclerosis, venous capillary insufficiency, obstructive arterial or venous retinopthies, senile macular degeneration, cycstoid macular edema or glaucoma, or the retinal ischemia may be associated with a tumor or injury to the mammal. Intravitreal injection of a compound of the invention also may be a preferred administration route to provide more direct treatment to the ischemic retina. The invention also provides methods for treatment of a subject suffering from shingles as well as treatment of a person suffering from or susceptible to migraines, particularly to alleviate the pain and discomfort associated with those disorders. These methods comprise administration of an effective amount of one or more compounds of the invention to a patient in need of treatment. The invention further provides a method of treating Korsakoff s disease, a chronic alcoholism-induced condition, comprising administering to a subject including a mammal, particularly a human, one or more compounds of the invention in an amount effective to treat the disease. Compounds of the invention are anticipated to have utility for the attenuation of cell loss, hemorrhages and/or amino acid changes associated with Korsakoff s disease. As discussed above, the invention also includes methods for treating a person suffering from or susceptible to cerebral palsy, emesis, narcotic withdrawal symptoms and age-dependent dementia, comprising administering to a subject including a mammal, particularly a human, one or more compounds of the invention in an amount effective to treat the condition. As discussed above, preferred compounds of the invention in a standard anticonvulsant in vivo audiogenic test, such as the audiogenic mouse assay of Example 48 which follows, where DBA/2 mice about 20-23 days old are injected intraperitoneally with a test compound 30 minutes prior to being placed in a bell jar with exposure to auditory stimulus of 12KHz sine wave at 110-120 db. References herein in vivo "audiogenic assay" are intended to refer to that protocol. Generally preferred compounds exhibit 20% or more inhibition (relative to subjects treated with vehicle control only) at a dose of 20 mg/kg, more preferably about 50% or more or 70% or more inhibition at a dose of 20 mg/kg in such an in vivo audiogenic assay. As discussed above, activity in the audiogenic assay has been recognized as indicative that a test compound has neuroprotective properties. See, e.g. , M. Tricklebank et al., European Journal of Pharmacology, supra; T. Seyfried, Federation Proceedings, supra. The invention also provides methods for determining binding activity of compounds of the invention as well as in vitro and in vivo binding activity diagnostic methods using one or more radiolabelled compounds of the invention, e.g., a compound of the invention that is labeled with 125 I, tritium, 32 P, "Tc, or the like, preferably 12S I. For instance, a compound of the invention having a phenyi or other aryl substiment that is ring substituted with one or more 125 I groups can be administered to a mammal and the subject then scanned for binding of the compound. Specifically, single photon emission computed tomography ("SPECT") can be employed to detect such binding. Such an analysis of the mammal could e.g. aid in the diagnosis and treatment of acute cerebral ischemia. That is, a labeled compound of the invention will selectively bind to ischemic tissue of e.g. a subject's brain to differentiate between ischemic and non- ischemic tissue and thereby assess trauma or other injury to the brain. Accordingly, the invention includes compounds of the invention that contain a radiolabel such as 125 I, tritium, 32 P, "Tc, or the like, preferably 125 I. Such radiolabelled compounds can be suitably prepared by procedures known in the synthesis art. For example, a compound of the invention having an aromatic group, such as phenyi, that has a bromo or chloro ring substituent can be employed in an exchange labeling reaction to provide the corresponding compound having an 125 I ring substiment. Compounds of the invention may be used in therapy in conjunction with other medicaments. For example, for treatment of a stroke victim or a person susceptible to stroke, one or more compounds of Formulae I, II, III, IV or V, or one or compounds of Formulae I", II", VI, VII, VIII or IX, may be suitably administered together with a pharmaceutical targeted for interaction in the blood clotting mechanism such as streptokinase, tPA, urokinase and other agents that lyse clots. Also, one or more compounds of the invention may be administered together with agents such as heparin and related heparin-based compounds, acenocoumarol or other known anticoagulants. The compounds of this invention can be administered intranasally, orally or by injection, e.g. , intramuscular, intraperitoneal, subcutaneous or intravenous injection, or by transdermal, intraocular or enteral means. The optimal dose can be determined by conventional means. Compounds of the present invention are suitably administered to a subject in the protonated and water-soluble form, e.g. , as a pharmaceutically acceptable salt of an organic or inorganic acid, e.g., hydrochloride, sulfate, hemi-sulfate, phosphate, nitrate, acetate, oxalate, citrate, maleate, mesylate, etc. Compounds of the invention can be employed, either alone or in combination with one or more other therapeutic agents as discussed above, as a pharmaceutical composition in mixture with conventional excipient, i.e. , pharmaceutically acceptable organic or inorganic carrier substances suitable for parenteral, enteral or intranasal application which do not deleteriously react with the active compounds and are not deleterious to the recipient thereof. Suitable pharmaceutically acceptable carriers include but are not limited to water, salt solutions, alcohol, vegetable oils, polyethylene glycols, gelatin, lactose, amylose, magnesium stearate, talc, silicic acid, viscous paraffin, perfume oil, fatty acid monoglycerides and diglycerides, petroethral fatty acid esters, hydroxymethyl-cellulose, polyvinylpyrrolidone, etc. The pharmaceutical preparations can be sterilized and if desired mixed with auxiliary agents, e.g., lubricants, preservatives, stabilizers, wetting agents, emulsifiers, salts for influencing osmotic pressure, buffers, colorings, flavorings and/or aromatic substances and the like which do not deleteriously react with the active compounds. For parenteral application, particularly suitable are solutions, preferably oily or aqueous solutions as well as suspensions, emulsions, or implants, including suppositories. Ampules are convenient unit dosages. For enteral application, particularly suitable are tablets, dragees or capsules having talc and/or carbohydrate carrier binder or the like, the carrier preferably being lactose and/or corn starch and/or potato starch. A syrup, elixir or the like can be used wherein a sweetened vehicle is employed. Sustained release compositions can be formulated including those wherein the active component is protected with differentially degradable coatings, e.g., by microencapsulation, multiple coatings, etc. Intravenous or parenteral administration, e.g., sub-cutaneous, intraperitoneal or intramuscular administration are preferred. The compounds of this invention are particularly valuable in the treatment of mammalian subjects, e.g. , humans, to provide neuroprotective therapy and/or prophylaxis. Typically, such subjects include those afflicted with neurodegenerative diseases such as Parkinson's disease, Huntington's disease, Amyotrophic Lateral Sclerosis, Alzheimer's disease, Down's Syndrome and Korsakoff s disease. Also suitable for treatment are those subjects suffering from or likely to suffer from nervous system dysfunctions resulting from, for example, epilepsy or nerve cell degeneration which is the result of hypoxia, hypoglycemia, brain or spinal chord ischemia or brain or spinal chord trauma. As discussed above, typical candidates for treatment include heart attack, stroke, brain or spinal cord injury patients, patients undergoing major surgery where brain or spinal cord ischemia is a potential complication and patients such as divers suffering from decompression sickness due to gas emboli in the blood stream. It will be appreciated that the actual preferred amounts of active compounds used in a given therapy will vary according to the specific compound being utilized, the particular compositions formulated, the mode of application, the particular site of administration, etc. Optimal administration rates for a given protocol of administration can be readily ascertained by those skilled in the art using conventional dosage determination tests conducted with regard to the foregoing guidelines. In general, a suitable effective dose of one or more compounds of Formulae I, II, III, IV or V, or one or compounds of Formulae I", II", VI, VII, VIII or IX, particularly when using the more potent compound(s) of Formulae I, II, III, IV or V, or one or compounds of Formulae I", II", VI, VII, VHI or IX, will be in the range of from 0.01 to 100 milligrams per kilogram of bodyweight of recipient per day, preferably in the range of from 0.01 to 20 milligrams per kilogram bodyweight of recipient per day, more preferably in the range of 0.05 to 4 milligrams per kilogram bodyweight of recipient per day. The desired dose is suitably administered once daily, or several sub-doses, e.g. 2 to 4 sub-doses, are administered at appropriate intervals through the day, or other appropriate schedule. Such sub-doses may be administered as unit dosage forms, e.g. , containing from 0.05 to 10 milligrams of compound(s) of Formulae I, II, III, IV or V, or one or compounds of Formulae I" , II", VI, VII, VIII or IX, per unit dosage, preferably from 0.2 to 2 milligrams per unit dosage. Compounds of the invention also should be useful as rubber accelerators. See U.S. Patent No. 1,411,713 for a discussion of rubber accelerator applications.

EXAMPLE 48: In vivo Anticonvulsant activity in the DBA/2 mouse model (Mouse audiogenic assay) The in vivo potency of compounds of the invention is exemplified by data summarized in the Table I below and obtained pursuant to the following protocol. Compounds were tested for their effectiveness in preventing seizures in DBA/2 mice which have a unique sensitivity to auditory stimulation. Exposure to loud high- frequency sounds can trigger seizure activity in these -tnimals. This sensitivity develops from postnatal day 12 and peaks around day 21 and slowly diminishes as the animals mature. The unusual response to auditory stimulation in this strain of mouse is believed to be due to a combination of early myelination (causing an unusually low excitatory threshold) and delayed development of inhibitory mechanisms. Mice were injected intraperitoneally with the compound specified in Table I below or with vehicle control, 30 minutes prior to being placed in a bell jar and turning on the auditory stimulus (12 KHz sine wave at 110-120 db). Administered doses are specified in Table I as milligram of compound per kilogram bodyweight of mouse. The auditory stimulus was left on for 60 seconds and mice reactions were timed and recorded. Percentage inhibition was determined with reference to vehicle controls. Results are shown in the Table I below. "FB" refers to free base. Table I Table I (Cont.) This invention has been described in detail with reference to preferred embodiments thereof. However, it will be appreciated that those skilled in the art, upon consideration of this disclosure, may make modifications and improvements within the spirit and scope of the invention.
