The present invention relates to Indenoisoquinolinone Analogs, compositions comprising an effective amount of an Indenoisoquinolinone Analog and methods for treating or preventing an inflammatory disease, a reperfusion injury, diabetes mellitus, a diabetic complication, reoxygenation injury resulting from organ transplantation, an ischemic condition, a neurodegenerative disease, renal failure, a vascular disease, a cardiovascular disease, cancer, a complication of prematurity, cardiomyopathy, retinopathy, nephropathy, neuropathy, erectile dysfunction or urinary incontinence, comprising administering to a subject in need thereof an effective amount of an Indenoisoquinolinone Analog.
Erectile dysfunction (“ED”) is a significant male-health issue. While estimating its prevalence is difficult, estimates range from about 15 million to 30 million sufferers worldwide.
The etiology of erectile dysfunction can be multiple, and can include mechanical trauma to the nerves (such as during prostatectomy), or it can be due to diabetes mellitus, cardiovascular diseases, induced by radiation, certain drugs, or advanced age.
Urinary incontinence affects people of all ages and levels of physical health, both in health care settings and in the community at large. Persons suffering from urinary incontinence can be predisposed to also having urinary-tract infections, pressure ulcers, perineal rashes and urosepsis. Psychosocially, urinary incontinence can be associated with embarrassment, social stigmatization, depression and a risk of institutionalization (Herzo et al., Annu. Rev. Gerontol. Geriatr. 9:74 (1989)).
An inflammatory disease, such as arthritis, colitis, and autoimmune diabetes, typically manifests itself as a disorder distinct from that associated with a reperfusion injury, e.g., stroke and heart attack, and can clinically manifest itself as a different entity. However, there can be common underlying mechanisms between these two types of disorders. Specifically, inflammatory disease and reperfusion injury can induce proinflammatory cytokine and chemokine synthesis which can, in turn, result in production of cytotoxic free radicals such as nitric oxide and superoxide. NO and superoxide can react to form peroxynitrite (ONOO−) (Szabó et al., Shock 6:79-88, 1996).
The ONOO−-induced cell necrosis observed in inflammatory disease and in reperfusion injury involves the activation of the nuclear enzyme poly (ADP-ribose) polymerase (PARP). Activation of PARP is thought to be an important step in the cell-mediated death observed in inflammation and reperfusion injury (Szabó al, Trends Pharmacol. Sci. 19:287-98, 1998).
A number of PARP inhibitors have been described in the art. See, e.g., Banasik et al., J. Biol. Chem., 267:1569-75, 1992, and Banasik et al., Mol. Cell. Biochem., 138:185-97, 1994; WO 00/39104; WO 00/39070; WO 99/59975; WO 99/59973; WO 99/11649; WO 99/11645; WO 99/11644; WO 99/11628; WO 99/11623; WO 99/11311; WO 00/42040; Zhang et al., Biochem. Biophys. Res. Commun., 278:590-98, 2000; White et al, J. Med. Chem., 43:4084-4097, 2000; Griffin et al., J. Med. Chem., 41:5247-5256, 1998; Shinkwin et al., Bioorg. Med. Chem., 7:297-308, 1999; and Soriano et al., Nature Medicine, 7:108-113, 2001. Adverse effects associated with administration of PARP inhibitors have been discussed in Milan et al., Science, 223:589-591, 1984.
Indenoisoquinolinone compounds have been previously discussed in the art. For example, cytotoxic non-camptothecin topoisomerase I inhibitors are reported in Cushman et al., J. Med. Chem., 43:3688-3698, 2300 and Cushman et al., J. Med. Chem. 42:446-57, 1999; indeno[1,2-c]isoquinolines are reported as antineoplastic agents in Cushman et al., WO 00/21537; and as neoplasm inhibitors in Hrbata et al., WO 93/05023.
Syntheses of indenoisoquinolinone compounds have been reported. For example, see Wawzonek et al., Org. Prep. Proc. Int., 14:163-8, 1982; Wawzonek et al., Can. J. Chem., 59:2833, 1981; Andoi et al, Bull. Chem. Soc. Japan, 47:1014-17, 1974; Dusemund et al., Arch. Pharm (Weinheim, Ger.), 3 17:381-2, 1984; and Lal et al., Indian J. Chem., Sect. B, 38B:33-39, 1999.
There remains, however, a need in the art for compounds useful for treating or preventing an inflammatory disease, a reperfusion injury, diabetes mellitus, a diabetic complication, reoxygenation injury resulting from organ transplantation, an ischemic condition, a neurodegenerative disease, renal failure, a vascular disease, a cardiovascular disease, cancer, a complication of prematurity, cardiomyopathy, retinopathy, nephropathy, neuropathy, erectile dysfunction or urinary incontinence.

The Indenoisoquinolinone Analog and other anticancer agent can act additively or synergistically. A synergistic combination of an Indenoisoquinolinone Analog and the other anticancer agent, might allow the use of lower dosages of one or both of these agents and/or less frequent administration of the agents to a subject with cancer. The ability to utilize lower dosages of one or both of the Indenoisoquinolinone Analog and other anticancer agent and/or to administer the agents less frequently can reduce any toxicity associated with the administration of the agents to a subject without reducing the efficacy of the agents in the treatment of cancer. In addition, a synergistic effect might result in the improved efficacy of these agents in the treatment of cancer and/or the reduction of any adverse or unwanted side effects associated with the use of either agent alone.
In one embodiment, the administration of an effective amount of an Indenoisoquinolinone Analog and an effective amount of another anticancer agent inhibits the resistance of a cancer to the other anticancer agent. In one embodiment, the cancer is a tumor.

The Indenoisoquinolinone Analogs can be administered to a subject that has undergone or is currently undergoing one or more additional anticancer therapies including, but not limited to, surgery, radiation therapy, or immunotherapy, such as cancer vaccines.
In one embodiment, the invention provides methods for treating or preventing cancer comprising administering to a subject in need thereof an effective amount of an Indenoisoquinolinone Analog to treat or prevent cancer and another anticancer therapy including, but not limited to, surgery, radiation therapy, or immunotherapy, such as a cancer vaccine.
In one embodiment, the other anticancer therapy is radiation therapy.
In another embodiment, the other anticancer therapy is surgery.
In still another embodiment, the other anticancer therapy is immunotherapy.
In a specific embodiment, the present methods for treating or preventing cancer comprise administering an effective amount of an Indenoisoquinolinone Analog and radiation therapy. The radiation therapy can be administered concurrently with, prior to, or subsequent to the Indenoisoquinolinone Analog, in one embodiment at least an hour, five hours, 12 hours, a day, a week, a month, in another embodiment several months (e.g., up to three months), prior or subsequent to administration of the Indenoisoquinolinone Analog.
Where the other anticancer therapy is radiation therapy, any radiation therapy protocol can be administered depending upon the type of cancer to be treated. For example, but not by way of limitation, X-ray radiation can be administered; specifically, high-energy megavoltage (radiation of greater that 1 MeV energy) can be administered for deep tumors, and electron beam and orthovoltage X-ray radiation can be administered for skin cancers. Gamma-ray emitting radioisotopes, such as radioactive isotopes of radium, cobalt and other elements, can also be administered.
Additionally, the invention provides methods of treatment of cancer comprising administering an Indenoisoquinolinone Analog as an alternative to chemotherapy or radiation therapy where the chemotherapy or the radiation therapy results in a negative side effect in the subject being treated. The subject being treated can, optionally, be treated with another anticancer therapy such as surgery, radiation therapy, or immunotherapy.
The Indenoisoquinolinone Analogs can also be administered in vitro or ex vivo, such as for the treatment of certain cancers, including, but not limited to leukemias and lymphomas, such treatment involving autologous stem cell transplants. This can involve a process in which the subject's autologous hematopoietic stem cells are harvested and purged of all cancer cells, the subject's remaining bone-marrow cell population is then eradicated via the administration of an Indenoisoquinolinone Analog and/or radiation, and the resultant stem cells are infused back into the subject. Supportive care can be subsequently provided while bone marrow function is restored and the subject recovers.
The Indenoisoquinolinone Analogs are useful for treating or preventing erectile dysfunction. Erectile dysfunction includes an inability to achieve or maintain a full erection, specifically that which is sufficient to achieve or maintain sexual intercourse. The inability can be a total inability, an inconsistent ability, or a tendency to maintain only a brief erection. Erectile dysfunction includes idiopathic erectile dysfunction, as well as that which can result, for example, from trauma, including mechanical trauma, specifically that resulting from surgery, to the nerves (such as during prostatectomy); diabetes mellitus; a cardiovascular disease, including atherosclerosis; radiation; or certain drugs. The erectile dysfunction can also be age-related.
In one embodiment, the erectile dysfunction results from prostate surgery.
In a further embodiment, the erectile dysfunction results from prostate nerve injury.
The Indenoisoquinolinone Analogs are also useful for treating or preventing urinary incontinence. Urinary incontinence can result, for example, from trauma, including mechanical trauma, specifically during childbirth or that resulting from surgery, to the nerves (such as during prostatectomy or gynecological surgery); diabetes mellitus; a cardiovascular disease, including atherosclerosis; radiation; or certain drugs. The urinary incontinence can also be age-related.
In one embodiment, the subject in need of urinary incontinence treatment or prevention is male.
In one embodiment, the subject in need of urinary incontinence treatment or prevention is female.
The Indenoisoquinolinone Analogs are also useful for treating or preventing a complication of prematurity. Examples of complications of prematurity include, but are not limited to, retinopathy, hyaline-membrane disease and necrotizing enterocolitis.
The Indenoisoquinolinone Analogs are also useful for treating or preventing cardiomyopathy.
The Indenoisoquinolinone Analogs are also useful for treating or preventing retinopathy.
The Indenoisoquinolinone Analogs are also useful for treating or preventing nephropathy.
The Indenoisoquinolinone Analogs are also useful for treating or preventing neuropathy.
Due to their activity, the Indenoisoquinolinone Analogs are advantageously useful in veterinary and human medicine. As described above, the Indenoisoquinolinone Analogs are useful for treating or preventing a Condition in a subject in need thereof.
The Indenoisoquinolinone Analogs can be administered in amounts that are effective to treat or prevent a Condition in a subject in need thereof.
When administered to a subject, the Indenoisoquinolinone Analogs can be administered as a component of a composition that comprises a physiologically acceptable carrier or vehicle. The present compositions, which comprise an Indenoisoquinolinone Analog, can be administered orally. The Indenoisoquinolinone Analogs can also be administered by any other convenient route, for example, by infusion or bolus injection, by absorption through epithelial or mucocutaneous linings (e.g., oral, rectal, or intestinal mucosa) and can be administered together with another biologically active agent. Administration can be systemic or local. Various delivery systems are known, e.g., encapsulation in liposomes, microparticles, microcapsules and capsules.
Methods of administration include, but are not limited to, intradermal, intramuscular, intraperitoneal, intravenous, subcutaneous, intranasal, epidural, oral, sublingual, intracerebral, intravaginal, transdermal, rectal, by inhalation, or topical, specifically to the ears, nose, eyes, or skin. In some instances, administration will result in the release of an Indenoisoquinolinone Analog into the bloodstream.
In one embodiment, the Indenoisoquinolinone Analogs are administered orally.
In other embodiments, it can be desirable to administer the Indenoisoquinolinone Analogs locally. This can be achieved, for example, and not by way of limitation, by local infusion during surgery, topical application, e.g., in conjunction with a wound dressing after surgery, by injection, by means of a catheter, by means of a suppository or enema, or by means of an implant, said implant being of a porous, non-porous, or gelatinous material, including membranes, such as sialastic membranes, or fibers.
In certain embodiments, it can be desirable to introduce the Indenoisoquinolinone Analogs into the central nervous system or gastrointestinal tract by any suitable route, including intraventricular, intrathecal, and epidural injection, and enema. Intraventricular injection can be facilitated by an intraventricular catheter, for example, attached to a reservoir, such as an Ommaya reservoir.
Pulmonary administration can also be employed, e.g., by use of an inhaler of nebulizer, and formulation with an aerosolizing agent, or via perfusion in a fluorocarbon oar, synthetic pulmonary surfactant. In certain embodiments, the Indenoisoquinolinone Analogs can be formulated as a suppository, with traditional binders and excipients such as triglycerides.
In another embodiment Indenoisoquinolinone Analogs can be delivered in a vesicle, specifically a liposome (see Langer, Science 249:1527-1533 (1990) and Treat or prevent et al., Liposomes in Therapy of Infectious Disease and Cancer 317-327 and 353-365 (1989)).
In yet another embodiment, the Indenoisoquinolinone Analogs can be delivered in a controlled-release system or sustained-release system (see, e.g., Goodson, in Medical Applications of Controlled Release, supra, vol. 2, pp. 115-138 (1984)). Other controlled or sustained-release systems discussed in the review by Langer, Science 249:1527-1533 (1990) can be used. In one embodiment a pump can be used (Langer, Science 249:1527-1533 (1990); Sefton, CRC Crit. Ref. Biomed. Eng. 14:201 (1987); Buchwald et al., Surgery 88:507 (1980); and Saudek et al., N. Engl. J. Med. 321:574 (1989)). In another embodiment polymeric materials can be used (see Medical Applications of Controlled Release (Langer and Wise eds., 1974); Controlled Drug Bioavailability, Drug Product Design and Performance (Smolen and Ball eds., 1984); Ranger and Peppas, J. Macromol. Sci. Rev. Macromol. Chem. 2:61 (1983); Levy et al., Science 228:190 (1935); During et al., Ann. Neural. 25:351 (1989); and Howard et al., J. Neurosurg. 71:105 (1989)).
In yet another embodiment a controlled- or sustained-release system can be placed in proximity of a target of the Indenoisoquinolinone Analogs, e.g., the spinal column, brain, skin, lung, or gastrointestinal tract, thus requiring only a fraction of the systemic dose.
The present compositions can optionally comprise a suitable amount of a pharmaceutically acceptable excipient so as to provide the form for proper administration to the subject.
Such pharmaceutical excipients can be liquids, such as water and oils, including those of petroleum, animal, vegetable, or synthetic origin, such as peanut oil, soybean oil, mineral oil, sesame oil and the like. The pharmaceutical excipients can be saline, gum acacia, gelatin, starch paste, talc, keratin, colloidal silica, urea and the like. In addition, auxiliary, stabilizing, thickening, lubricating, and coloring agents can be used. In one embodiment, the pharmaceutically acceptable excipients are sterile when administered to a subject. Water is a useful excipient when the Indenoisoquinolinone Analog is administered intravenously. Saline solutions and aqueous dextrose and glycerol solutions can also be employed as liquid excipients, specifically for injectable solutions. Suitable pharmaceutical excipients also include starch, glucose, lactose, sucrose, gelatin, malt, rice, flour, chalk, silica gel, sodium stearate, glycerol monostearate, talc, sodium chloride, dried skim milk, glycerol, propylene, glycol, water, ethanol and the like. The present compositions, if desired, can also contain minor amounts of wetting or emulsifying agents, or pH buffering agents.
The present compositions can take the form of solutions, suspensions, emulsion, tablets, pills, pellets, capsules, capsules containing liquids, powders, sustained-release formulations, suppositories, emulsions. aerosols, sprays, suspensions, or any other form suitable for use. In one embodiment, the composition is in the form of a capsule (see e.g. U.S. Pat. No. 5,698,155). Other examples of suitable pharmaceutical excipients are described in Remington's Pharmaceutical Sciences 1447-1676 (Alfonso R. Gennaro eds., 19th ed. 1995), incorporated herein by reference.
In one embodiment, the Indenoisoquinolinone Analog is formulated in accordance with routine procedures as a composition adapted for oral administration to human beings. Compositions for oral delivery can be in the form of tablets, lozenges, aqueous or oily suspensions, granules, powders, emulsions, capsules, syrups, or elixirs for example. Orally administered compositions can contain one or more agents, for example, sweetening agents such as fructose, aspartame or saccharin; flavoring agents such as peppermint, oil of wintergreen, or cherry; coloring agents; and preserving agents, to provide a pharmaceutically palatable preparation. Moreover, where in tablet or pill form, the compositions can be coated to delay disintegration and absorption in the gastrointestinal tract thereby providing a sustained action over an extended period of time. Selectively permeable membranes surrounding an osmotically active driving an Indenoisoquinolinone Analog are also suitable for orally administered compositions. In these latter platforms, fluid from the environment surrounding the capsule is imbibed by the driving compound, which swells to displace the agent or agent composition through an aperture. These delivery platforms can provide an essentially zero order delivery profile as opposed to the spiked profiles of immediate release formulations. A time-delay material such as glycerol monostearate or glycerol stearate can also be useful. Oral compositions can include standard excipients such as mannitol, lactose, starch, magnesium stearate, sodium saccharin, cellulose, and magnesium carbonate. In one embodiment, the excipients are of pharmaceutical grade.
In another embodiment, the Indenoisoquinolinone Analogs can be formulated for intravenous administration. Typically, compositions for intravenous administration comprise sterile isotonic aqueous buffer. Where necessary, the compositions can also include a solubilizing agent. Compositions for intravenous administration can optionally include a local anesthetic such as lignocaine to lessen pain at the site of the injection. Generally, the ingredients are supplied either separately or mixed together in unit dosage form, for example, as a dry lyophilized-powder or water-free concentrate in a hermetically sealed container such as an ampule or sachette indicating the quantity of active agent. Where the Indenoisoquinolinone Analogs are to be administered by infusion, they can be dispensed, for example, with an infusion bottle containing sterile pharmaceutical grade water or saline. Where the Indenoisoquinolinone Analogs are administered by injection, an ampule of sterile water for injection or saline can be provided so that the ingredients can be mixed prior to administration.
Indenoisoquinolinone Analogs can be administered by controlled-release or sustained-release means or by delivery devices that are well known to those of ordinary skill in the art. Examples include, but are not limited to, those described in U.S. Pat. Nos. 3,845,770; 3,916,899; 3,536,809; 3,598,123; 4,008,719; 5,674,533; 5,059,595; 5,591,767; 5,120,548; 5,073,543; 5,639,476; 5,354,556; and 5,733,556, each of which is incorporated herein by reference in its entirety. Such dosage forms can be useful for providing controlled- or sustained-release of one or more active ingredients using, for example, hydropropylmethyl cellulose, other polymer matrices, gels, permeable membranes, osmotic systems, multilayer coatings, microparticles, liposomes, microspheres, or a combination thereof to provide the desired release profile in varying proportions. Suitable controlled- or sustained-release formulations known to those skilled in the art, including those described herein, can be readily selected for use with the active ingredients of the invention. The invention thus encompasses single unit dosage forms suitable for oral administration such as, but not limited to, tablets, capsules, gelcaps, and caplets that are adapted for controlled- or sustained-release.
In one embodiment a controlled- or sustained-release composition comprises a minimal amount of an Indenoisoquinolinone Analog to treat or prevent the Condition over a period of time. Advantages of controlled- or sustained-release compositions include extended activity of the drug, reduced dosage frequency, and increased subject compliance. In addition, controlled- or sustained-release compositions can favorably affect the time of onset of action or other characteristics, such as blood levels of the Indenoisoquinolinone Analog, and can thus reduce the occurrence of adverse side effects.
Controlled- or sustained-release compositions can initially release an amount of an Indenoisoquinolinone Analog that promptly produces the desired therapeutic or prophylactic effect, and gradually and continually release other amounts of the Indenoisoquinolinone Analog to maintain this level of therapeutic or prophylactic effect over an extended period of time. To maintain a constant level of the Indenoisoquinolinone Analog in the body, the Indenoisoquinolinone Analog can be released from the dosage form at a rate that will replace the amount of Indenoisoquinolinone Analog being metabolized and excreted from the body. Controlled- or sustained-release of an active ingredient can be stimulated by various conditions, including but not limited to, changes in pH, changes in temperature, concentration or availability of enzymes, concentration or availability of water, or other physiological conditions or compounds.
The amount of the Indenoisoquinolinone Analog that is effective in the treatment or prevention of a Condition can be determined by standard clinical techniques. In addition, in vitro or in vivo assays can optionally be employed to help identify optimal dosage ranges. The precise dose to be employed can also depend on the route of administration, and the seriousness of the condition being treated and can be decided according to the judgment of the practitioner and each subject's circumstances in view of, e.g., published clinical studies. Suitable effective dosage amounts, however, range from about 10 micrograms to about 5 grams about every 4 hours, although they are typically about 500 mg or less per every 4 hours. In one embodiment, the effective dosage is about 0.01 mg, 0.5 mg, about 1 mg, about 50 mg, about 100 mg, about 200 mg, about 300 mg, about 400 mg, about 500 mg, about 600 mg, about 700 mg, about 800 mg, about 900 mg, about 1 g, about 1.2 g, about 1.4 g, about 1.6 g, about 1.8 g, about 2.0 g, about 2.2 g, about 2.4 g, about 2.6 g, about 2.8 g, about 3.0 g, about 3.2 g, about 3.4 g, about 3.6 g, about 3.8 g, about 4.0 g, about 4.2 g, about 4.4 g, about 4.6 g, about 4.8 g, and about 5.0 g, every 4 hours. Equivalent dosages can be administered over various time periods including, but not limited to, about every 2 hours, about every 6 hours, about every 8 hours, about every 12 hours, about every 24 hours, about every 36 hours, about every 48 hours, about every 72 hours, about every week, about every two weeks, about every three weeks, about every month, and about every two months. The effective dosage amounts described herein refer to total amounts administered; that is, if more than one Indenoisoquinolinone Analog is administered, the effective dosage amounts correspond to the total amount administered.
Compositions can be prepared according to conventional mixing, granulating or coating methods, respectively, and the present compositions can contain, in one embodiment, from about 0.1% to about 99%; and in another embodiment from about 1% to about 70% of the Indenoisoquinolinone Analog by weight or volume.
The dosage regimen utilizing the Indenoisoquinolinone Analog can be selected in accordance with a variety of factors including type, species, age, weight, sex and medical condition of the subject; the severity of the condition to be treated; the route of administration; the renal or hepatic function of the subject; and the specific Indenoisoquinolinone Analog employed. A person skilled in the art can readily determine the effective amount of the drug useful for treating or preventing the Condition.
An Indenoisoquinolinone Analog can be administered in a single daily dose, or the total daily dosage can be administered in divided doses of two, three or four times daily. Furthermore, an Indenoisoquinolinone Analog can be administered in intranasal form via topical use of suitable intranasal vehicles, or via transdermal routes, using those forms of transdermal skin patches well known to those of ordinary skill in that art. To be administered in the form of a transdermal delivery system, the dosage administration can be continuous rather than intermittent throughout the dosage regimen. Other illustrative topical preparations include creams, ointments, lotions, aerosol sprays and gels, wherein the concentration of Indenoisoquinolinone Analog ranges from about 0.1% to about 15%, w/w or w/v.
The Indenoisoquinolinone Analogs can be assayed in vitro or in vivo for the desired therapeutic or prophylactic activity prior to use in humans. Animal model systems can be used to demonstrate safety and efficacy.
The present methods for treating or preventing a Condition in a subject in need thereof can further comprise administering another prophylactic or therapeutic agent to the subject being administered an Indenoisoquinolinone Analog. In one embodiment, the other prophylactic or therapeutic agent is administered in an effective amount. The other prophylactic or therapeutic agent includes, but is not limited to, an anti-inflammatory agent, an anti-renal failure agent, an anti-diabetic agent, and anti-cardiovasculare disease agent, an antiemetic agent, a hematopoietic colony stimulating factor, an anxiolytic agent, and an analgesic agent.
In one embodiment, the other prophylactic or therapeutic agent is an agent useful for reducing any potential side effect of an Indenoisoquinolinone Analog.

In one embodiment, the Indenoisoquinolinone Analog can be administered prior to, concurrently with, or after an anti-inflammatory agent, or on the same day, or within 1 hour, 2 hours, 12 hours, 24 hours, 48 hours or 72 hours of each other.
In another embodiment, the Indenoisoquinolinone Analog can be administered prior to, concurrently with, or after an anti-renal failure agent, or on the same day, or within 1 hour, 2 hours, 12 hours, 24 hours, 48 hours or 72 hours of each other.
In still another embodiment, the Indenoisoquinolinone Analog can be administered prior to, concurrently with, or after an anti-diabetic agent, or on the same day, or within 1 hour, 2 hours, 12 hours, 24 hours, 48 hours or 72 hours of each other.
In yet another embodiment, the Indenoisoquinolinone Analog can be administered prior to, concurrently with, or after an anti-cardiovascular disease agent, or on the same day, or within 1 hour, 2 hours, 12 hours, 24 hours, 48 hours or 72 hours of each other.
In a further embodiment, the Indenoisoquinolinone Analog can be administered prior to, concurrently with, or after an antiemetic agent, or on the same day, or within 1 hour, 2 hours, 12 hours, 24 hours, 48 hours or 72 hours of each other.
In another embodiment, the Indenoisoquinolinone Analog can be administered prior to, concurrently with, or after a hematopoietic colony stimulating factor, or on the same day, or within 1 hour, 2 hours, 12 hours, 24 hours, 48 hours, 72 hours, 1 week, 2 weeks, 3 weeks or 4 weeks of each other.
In still embodiment, the Indenoisoquinolinone Analog can be administered prior to, concurrently with, or after an opioid or non-opioid analgesic agent, or on the same day, or within 1 hour, 2 hours, 12 hours, 24 hours, 48 hours or 72 hours of each other.
In yet another embodiment, the Indenoisoquinolinone Analog can be administered prior to, concurrently with, or after an anxiolytic agent, or on the same day, or within 1 hour, 2 hours, 12 hours, 24 hours, 48 hours or 72 hours of each other.
Effective amounts of the other prophylactic or therapeutic agents are well known to those skilled in the art. However, it is well within the skilled artisan's purview to determine the other prophylactic or therapeutic agent's optimal effective amount range. In one embodiment of the invention, where another prophylactic or therapeutic agent is administered to a subject, the effective amount of the Indenoisoquinolinone Analog is less than its effective amount would be where the other prophylactic or therapeutic agent is not administered. In this case, without being bound by theory, it is believed that Indenoisoquinolinone Analogs and the other prophylactic or therapeutic agent act synergistically to treat or prevent a Condition.
In one embodiment, the other therapeutic or prophylactic agent is an anti-inflammatory agent.

1H-NMR spectra were obtained using Varian 300 MHz spectrophotometer and chemical shifts (6) are reported in parts per million (ppm). 1H-NMR spectra were obtained using DMSO-d6 or CDCl3 as solvents. Analytical thin layer chromatography (TLC) was performed using TLC plates pre-coated with silica gel 60 F-254. Compounds were visualized with short wavelength UV light. All final compounds were characterized on the basis of 1H-NMR or mass-spectrometry (MS) data. Homophthalic anhydride, 2-methyl-3-bromobenzoic acid, benzonitrile, and 3-methyl-4-bromobenzoic acid were obtained commercially (Sigma-Aldrich Corp., St. Louis, Mo.).
2 mL of concentrated sulfuric acid were added to a solution of 3-bromo-2-methylbenzoic acid (20 g, 93 mmol) in methanol (150 mL). The resultant mixture was refluxed for 6 hours. Methanol was removed under reduced pressure, and the residue was dissolved in a mixture of chloroform (100 mL) and saturated solution of Na2CO3 (100 mL). The organic layer was separated and washed with brine, dried over Na2SO4 and concentrated to provide methyl 3-bromo-2-methylbenzoate (21.1 g). 1H NMR spectrum (in DMSO-d6): δ 7.79 (d, J=8.0 Hz, 1H); 7.69 (d, J=7.9 Hz, 1H); 7.23 (t, 1H); 3.82 (s, 3H).
To a flask was added methyl 3-bromo-2-methylbenzoate (21 g, 91.7 mmol), potassium hexacyanoferrate (II) trihydrate (9.7 g, 22.9 mmol), Na2CO3 (9.7 g, 91.7 mmol) and Pd(OAc)2 (102 mg) in N,N-dimethylacetamide (100 mL). The flask's atmosphere was evacuated and replaced with nitrogen, and the reaction mixture heated at 120° C. for 10 hours. The reaction mixture was cooled to room temperature and diluted with ethyl acetate (150 mL). The resultant slurry was filtered and washed thoroughly with ethyl acetate (2×50 mL). The combined filtrate was washed with brine and water, dried over Na2SO4 and evaporated under reduced pressure. The residue obtained after the concentration was purified using flash chromatography (ethyl acetate-hexanes (1:9) as the eluent) to provide methyl 3-cyano-2-methylbenzoate (11.2 g, 70% yield). 1H NMR spectrum (in DMSO-d6): δ 8.03 (d, J=8.1 Hz, 1H); 7.98 (d, J=7.9 Hz, 1H); 7.49 (t, 1H); 3.84 (s, 3H); 2.65 (s, 3H).
A suspension of methyl 3-cyano-2-methylbenzoate (10.6 g, 60.5 mmol), NBS (16.2 g, 90.7 mmol) and azobisisobutyronitrile (AIBN) (100 mg) in tetrachloromethane (200 mL) was refluxed under nitrogen atmosphere for 6 hours. TLC analysis indicated the complete consumption of methyl 3-cyano-2-methylbenzoate (TLC solvent: 10% ethyl acetate in hexane). The reaction mixture was filtered and washed with chloroform (3×20 mL). The combined filtrate and washings were concentrated under reduced pressure. The residue was washed through a short column of silica gel using 10% ethyl acetate in hexanes as an eluent. The eluent was concentrated and the resultant product dried under vacuum overnight to provide 15.1 g of methyl 2-bromomethyl-3-cyanobenzoate (98% yield). 1H NMR spectrum (in DMSO-d6): δ 8.15 (d, J=8.0 Hz, 1H); 8.12 (d, J=7.9 Hz, 1H); 7.67 (t, 1H); 5.04 (s, 2H); 3.89 (s, 3H).
A mixture of methyl 2-bromomethyl-3-cyanobenzoate (14.1 g, 55.5 mmol) and homophthalic anhydride (22.5 g, 138.8 mmol) in acetonitrile (150 mL) was stirred at room temperature. A solution of triethylamine (23.2 mL) in acetonitrile (100 mL) was added dropwise over the period of 1 hour. After the completion of addition, the resultant suspension was refluxed for 4 hours. The reaction mixture was then cooled to room temperature and filtered. The resultant solid was washed thoroughly with acetonitrile (100 mL) and ethanol (2×100 mL) and dried in vacuum oven at 50° C. to provide methyl 5,6-dihydro-5-oxo-11-H-indeno[1,2-c]isoquinoline-10-carboxylate was obtained in 81% yield (13.1 g). 1H NMR spectrum (in DMSO-d6): δ 12.21 (s, 1H); 8.20 (m, 2H); 7.83 (d, J=7.5 Hz, 1H); 7.71 (m, 2H); 7.47 (m, 2H); 4.07 (s, 2H); 3.89 (s, 3H).
Fine powder of methyl 5,6-dihydro-5-oxo-11-H-indeno[1,2-c]isoquinoline-10-carboxylate (11.3 g, 28.8 mmol) was suspended in THF (150 mL) and stirred at room temperature. A 2M solution of Lithium aluminium hydride (LAH) in THF (39 mL) was added slowly to the stirred suspension. After the complete addition, the mixture was stirred at room temperature for 6 hours, then cooled to 0° C. The reaction mixture was quenched with dropwise addition of ethyl acetate (50 mL). During the quenching the reaction temperature was kept below 50° C. The reaction mixture was poured into 1N HCl solution (200 mL) and stirred for 1 hour. The resultant solid was collected by filtration, washed with 1N HCl solution (20 mL) and ethyl acetate, and dried in a vacuum oven overnight to provide 10-hydroxymethyl-5,6-dihydro-5-oxo-11-H-indeno[1,2-c]isoquinoline in 93% yield (9.5 g). 1H NMR spectrum (in DMSO-d6): δ 12.28 (s, 1H); 8.23 (d, J=8.1 Hz, 1H); 7.89 (m, 1H); 7.73 (m, 2H); 7.45 (m, 1H); 7.36 (m, 2H); 5.22 (d, J=5.1 Hz, 1H), 4.68 (d, 2H); 3.85 (s, 2H).
Fine powder of 10-hydroxymethyl-5,6-dihydro-5-oxo-11-H-indeno[1,2-c]isoquinoline (7.3 g, 27.7 mmol) was suspended in THF (150 mL). A solution of PBr3 (83 mL, 1M in dichloromethane) was added dropwise at room temperature. After the complete addition, the resultant mixture was stirred overnight and quenched by addition of water (150 mL). The suspension was stirred for 1 hour and filtered. The resultant solid was washed with water (2×100 mL) and ethyl acetate (2×100 mL) and dried in a vacuum oven to provide 110-Bromomethyl-5,6-dihydro-5-oxo-11-H-indeno[1,2-c]isoquinoline in 81% yield. 1H NMR spectrum (in DMSO-d6): δ 12.31 (s, 1H); 8.23 d, J=7.5 Hz, 1H); 7.95 (m, 1H); 7.75 (m, 2H); 7.45 (m, 2H); 4.87 (s, 2H); 3.97 (s, 2H).

The ability of an illustrative Indenoisoquinolinone Analog to inhibit PARP and prevent peroxynitrite induced cytotoxicity can be demonstrated using methods described in Virag et al., Br. J. Pharmacol. 1999, 126(3):769-77; and Immunology 1998, 94(3):345-55.
The potency of inhibition of purified PARP enzyme can be subsequently determined for selected Indenoisoquinolinone Analogs, and the potency is compared with that of 3-aminobenzamide, a prototypical benchmark PARP inhibitor. The assay is performed in 96 well ELISA plates according to instructions provided with a commercially available PARP inhibition assay kit (for example, from Trevigen, Gaithersburg, Md.).
Using an in vitro, oxidant-stimulated thymocyte assay (described, in detail, in Virag et al., Immunology 94(3):345-55, 1998), an illustrative Indenoisoquinolinone Analog can be tested for its ability to prevent the oxidant-induced suppression of the viability of the cells and as such, this assay represents an in vitro model of reperfusion related cell death in ischemic organs.
The effect of an illustrative Indenoisoquinolinone Analog can be determined using a systemic inflammatory model induced by bacterial lipopolysaccharide (LPS), which is reported to be responsible for causing reperfusion injurys and inflammatory diseases such as septic shock and systemic inflammatory response syndrome in animals (see Parrillo, N. Engl. J. Med., 328:1471-1478 (1993) and Lamping, J. Clin. Invest. 101:2065-2071 (1998).
The efficacy of an illustrative Indenoisoquinolinone Analog in a mouse model of ischemic and reperfused gut can be determined according to the method described in Liaudet et al., Shock 2000, 14(2):134-41.
In another set of experiments, the effect of an illustrative Indenoisoquinolinone Analog in a rat model of middle cerebral artery occlusion/reperfusion can be assayed as described in Abdelkarim et al, Int. J. Mol. Med. 2001, 7(3):255-60.
PARP inhibitors and PARP deficiency are known to reduce the development of diabetes mellitus and the incidence of diabetic complications. The anti-diabetic effect of an illustrative Indenoisoquinolinone Analog can be determined using a single high-dose streptozotocin model of diabetes mellitus, which can be used as conducted as described in Mabley et al., Br. J. Pharmacol. 2001, 133(6):909-9; and Soriano et al., Nat. Med. 2001, 7(1): 108-13. Briefly, 160 mg/kg streptozotocin is injected to mice treated with vehicle (control) or with an illustrative Indenoisoquinolinone Analog intraperitoneally (3 mg/kg) and 3 days later blood sugar levels are determined using a blood glucose meter.
Experiments are conducted in male Sprague-Dawley rats according to previously published methods for forceps-induced nerve crush injury and erectile function measurements (Rehman, J., et al., Urology 51:640-644, 1998; Sezen, S. F., et al., Int. J. Impot. Res. 14:506-12, 2002). Subjects are anesthetized with Phenobarbital. The prostate of the subjects is exposed and the cavernosal nerve is clipped on either side with a forceps to induce mechanical injury (crush). This rat model mimics the nerve injury that develops during human male prostatectomy, leading to nerve injury and subsequent erectile dysfunction. Subjects are studied 2 weeks after the injury. Two groups of subjects are used, one group treated with vehicle and one group treated with an illustrative Indenoisoquinolinone Analog. The illustrative Indenoisoquinolinone Analog is injected at 30 mg/kg i.v. immediately before the crush injury, and on the following day at the same dose. Thereafter, for 12 days, subjects are treated with 60 mg/kg of the illustrative Indenoisoquinolinone Analog intraperitoneally. At 2 weeks, subjects are re-anesthetized and measured for mean arterial blood pressure (MAP) and intracavernosal pressure (ICP). Cavernosal nerve stimulation is conducted at 5 and 7.5 V using a square pulse stimulator for 30 msec. ICP is determined as the area under curve (mmHg×sec). In addition, IPC/MAP ratios are determined.
Demonstration of Indenoisoquinolinone Analogs' ability to inhibit PARP and prevent peroxynitrite induced cytotoxicity was shown using methods described in Virag et al., Br. J. Pharmacol. 1999, 126(3):769-77; and Immunology 1998, 94(3):345-55. The murine RAW macrophages (ATCC, American Type Culture Collection, Manassas, Va.) were grown in RPMI 1650 (Invitrogen Life Technologies; Carlsbad, Calif.) medium supplemented with 10% heat-inactivated FBS, 2 mM L-glutamine, and 100 U/ml of penicillin and streptomycin. Cells, between passages 5 and 15, were seeded at a density of 250,000 cells/well in 12 well plates and allowed to grow 48 hours before use. Growth medium was changed on the day of use. Cells were treated with an Indenoisoquinolinone Analog diluted in a growth medium supplemented with 10% fetal bovine serum (FBS) for 1 hour prior to the addition of hydrogen peroxide (0.5 mM) for a further 25 minutes. For the measurement of PARP activity, media was removed and replaced with 0.5 ml of the assay buffer (56 mM HEPES-pH 7.5, 28 mM KCl, 28 mM NaCl, 2 mM MgCl2, 0.01% digitonin, and 0.5 μCi/ml of 3H-NAD+) for 20 minutes. After aspirating the assay buffer, cells were lysed and transferred to eppendorf tubes containing 250 μl of 50% ice-cold trichloroacetic acid (TCA), which were then placed at 4° C. for 4 hours. Samples were centrifuged at 10,000 g for 10 minutes and supernatant removed. The pellets were washed twice with 500 μl of ice-cold 5% w/v TCA. The pellets were then solubilized in 250 μl of NaOH (0.1 M) containing 2% SDS overnight at 37° C. and the PARP activity was then determined by measuring the radioactivity incorporated using a Wallac scintillation counter. The solubilized protein (250 μl) was mixed with 5 ml of scintillation fluid (ScintiSafe Plus, Fisher Scientific) before being counted for 3 minutes. EC50 values were determined from a dose-response curve.
