  • This is a Divisional of U.S. application Ser. No. 10/505,012 filed Aug. 18, 2004, which is a 371 of PCT Application No. PCT/JP03/01694, Feb. 18, 2003, which claims priority from Japanese Application No. 2002-42259 filed on Feb. 19, 2002 and 2002-199673 filed on Jul. 9, 2002. The above-noted applications are incorporated herein by reference in their entirety.
    • TECHNICAL FIELD
  • The present invention relates to fused pyridazine derivative compounds.
  • More particularly, the present invention relates to
  • (1) pyridazine derivative compounds represented by formula (I)
  • Figure US20080261947A1-20081023-C00002
  • (wherein all symbols have the same meanings as described below), or pharmaceutically acceptable salts thereof,
    (2) a process for preparing thereof, and
    (3) an agent comprising the same as an active ingredient.
    • BACKGROUND ART
  • Poly(ADP-ribose)polymerase (abbreviated as PARP hereinafter), which is a nuclear enzyme activated by DNA strand breaks, plays a role in the transfer reaction of ADP-ribose moiety from nicotinamide adenine dinucleotide (abbreviated as NAD+ hereinafter) to various proteins such as histones, DNA-polymerases and DNA-topoisomerases, etc.
  • DNA strand breaks caused by Peroxynitrite (ONOO−) and oxygen radicals lead to overactivation of PARP (PARP is activated up to 100 times when Zn finger domain of PARP binds to DNA with nicks.). It is thought that overactivation of PARP causes depletion of NAD+, which is essential for electron transport system, and consequently depletion of ATP, leading to energy failure, ultimately resulting in cell death. (The suicide hypothesis of PARP activation: Free Radic. Biol Med., 21, 855 (1996); TIPS., 19, 287 (1998)). Therefore, it is considered that PARP inhibitor is useful as inhibitor of cell death.
  • Since caspase-3, which is one of interleukin-1β-converting enzyme family, specifically cleaves PARP as the substrate (Cell., 81, 801 (1995)), it is suggested PARP is associated with apoptosis.
  • It is reported that 3-aminobenzamide and nicotinamide generally known as inhibitors of PARP are useful for inhibition of cell death and improvement of diseases on various models of ischemic diseases (cerebral, myocardial, intestinal, skeletal muscular or retinal ischemia etc.), inflammatory diseases (arthritis, inflammatory bowel disease or multiple sclerosis etc.), diabetes, shock, extrapyramidal disease (TIPS., 19, 287 (1998); Eur J. Pharmacol., 350, 1 (1998)) and hyperalgesia (Pain, 72, 355 (1997)) in vitro, in vivo and in PARP knockout mouse. And it is reported that PARP inhibitor is useful as an antiretroviral drug such as an anti HIV drug (Biochem. Biophys. Res. Commum., 180, 504 (1991)), a sensitizer of anticancer therapy (Radiat. Res., 126, 367 (1991); Br. J. Cancer., 72, 849 (1995)) or an immunosuppressant (Int. J. Immunopharmac., 17, 265 (1995)).
  • PARP inhibitor is useful for prevention and/or treatment of various diseases, for example, ischemic diseases (cerebral infarction, myocardial infarction, reperfusion injury or postoperative injury etc.), inflammatory diseases (inflammatory bowel disease, multiple sclerosis, arthritis or lung injury etc.), neurodegenerative disorders (extrapyramidal disease, Parkinson's disease, Alzheimer's disease, muscular dystrophy or lumbar spinal canal stenosis etc.), glaucoma, diabetes, diabetic complication, shock, head trauma, spinal cord injury, renal failure, hyperalgesia or blood flow obstruction etc. And it is useful as an antiretroviral drug such as an anti HIV drug, a sensitizer of anticancer therapy or an immunosuppressant.

  • The method of amidation is known. For example, it includes the method
  • (1) an acyl halide,
  • (2) via a mixed acid anhydride,
  • (3) using a condensing agent.
  • These methods are explained as follows.
  • (1) The method via an acyl halide may be carried out, for example, by reacting carboxylic acid with an acyl halide (e.g., oxalyl chloride or thionyl chloride etc.) in an organic solvent (e.g., chloroform, methylene chloride, diethyl ether or tetrahydrofuran) or without a solvent at −20° C. to reflux temperature. And then the obtained acyl halide derivative may be reacted with amine in an inert organic solvent (e.g., chloroform, methylene chloride, diethyl ether or tetrahydrofuran) in the presence of tertiary amine (e.g., pyridine, triethylamine, dimethylaniline or dimethylaminopyridine etc.) at 0 to 40° C. As an alternative, the obtained acyl halide derivative may be reacted in an organic solvent (dioxane, tetrahydrofuran) using an alkaline aqueous solution (e.g., sodium bicarbonate, sodium hydroxide) at 0 to 40° C.
  • (2) The method via a mixed acid anhydride may be carried out, for example, by reacting carboxylic acid with an acyl halide (e.g., pivaloyl chloride, tosyl chloride or mesyl chloride) or an acid derivative (ethyl chloroformate or isobutyl chloroformate) in an organic solvent (e.g., chloroform, methylene chloride, diethyl ether, tetrahydrofuran) or without a solvent, in the presence of tertiary amine (e.g., pyridine, triethylamine, dimethylaniline or dimethylaminopyridine) at 0 to 40° C. And then the obtained mixed acid anhydride derivative may be reacted with amine in an organic solvent (e.g., chloroform, methylene chloride, diethyl ether or tetrahydrofuran), at 0 to 40° C.
  • (3) The method using a condensing agent may be carried out, for example, by reacting carboxylic acid with amine in an organic solvent (e.g., chloroform, methylene chloride, dimethylformamide, diethyl ether or tetrahydrofuran) or without a solvent, in the presence or absence of tertiary amine (e.g., pyridine, triethylamine, dimethylaniline or dimethylaminopyridine), using a condensing agent (e.g., 1,3-dicyclohexyl carbodiimide (DCC), 1-ethyl-3-[3-(dimethylamino)propyl]carbodiimide (EDC), 1,1′-carbodiimidazole (CDI), 2-chloro-1-methylpyridinium iodide, or 1-propanephosphonic acid cyclic anhydride (PPA)), in the presence or absence of 1-hydroxybenzothiazole (HOBt), at 0 to 40° C.
  • The reaction described in (1), (2) and (3) may be carried out under an inert gas (e.g., argon, nitrogen) to avoid water in order to obtain a preferable result.
  • The removal of the protective group may be carried out by following method.
  • The reaction for removing the protective group for carboxyl, hydroxyl, amino, amidino or guanidino is well known, including, for example, the following:
  • (1) alkali hydrolysis,
  • (2) deprotection under acidic condition,
  • (3) deprotection through hydrogenolysis,
  • (4) silyl deprotection.
  • These methods are explained as follows.
  • (1) The deprotection through alkali hydrolysis may be effected, for example, in an organic solvent (e.g., methanol, tetrahydrofuran, dioxane) by the use of an alkali metal hydroxide (e.g., sodium hydroxide, potassium hydroxide, lithium hydroxide), an alkaline earth metal hydroxide (e.g., barium hydroxide, calcium hydroxide) or a carbonate (e.g., sodium carbonate, potassium carbonate), or an aqueous solution thereof or their mixture, at 0 to 40° C.
  • (2) The deprotection under acidic condition may be effected, for example, in an organic solvent (e.g., dichloromethane, chloroform, dioxane, ethyl acetate, anisole) with an organic solvent (e.g., acetic acid, trifluoroacetic acid, methanesulfonic acid, p-toluenesulfonic acid) or an inorganic acid (e.g., hydrochloric acid, sulfuric acid) or their mixture (hydrogen bromide/acetic acid), at 0 to 100° C.
  • (3) The deprotection through hydrogenolysis may be effected, for example, in a solvent (e.g., ether-type (e.g., tetrahydrofuran, dioxane, dimethoxyethane, diethyl ether), alcohol-type (e.g., methanol, ethanol), benzene-type (e.g., benzene, toluene), ketone-type (e.g., acetone, methyl ethyl ketone), nitrile-type (e.g., acetonitrile), amide-type (e.g., dimethylformamide), water, ethyl acetate, acetic acid, or mixed solvent of two or more of these), in the presence of a catalyst (e.g., palladium-carbon, palladium-black, palladium hydroxide, platinum oxide, Raney nickel), in a normal-pressure or increased-pressure hydrogen atmosphere or in the presence of ammonium formate, at 0 to 200° C.
  • (4) The silyl deprotection may be effected, for example, in a water-miscible organic solvent (e.g., tetrahydrofuran, acetonitrile) by the use of tetrabutylammonium fluoride, at 0 to 40° C.
  • The carboxyl-protective group includes, for example, methyl, ethyl, t-butyl and benzyl.
  • The hydroxyl-protective group includes, for example, methoxymethyl, 2-tetrahydropyranyl, t-butyldimethylsilyl, t-butyldiphenylsilyl, acetyl and benzyl.
  • The amino, amidino and guanidino-protective group includes, for example, benzyloxycarbonyl, t-butoxycarbonyl, trifluoroacetyl, 9-fluorenylmethoxycarbonyl and trimethylsilyl.
  • The carboxyl, hydroxyl, amino, amidino or guanidino-protective group may be any others than those mentioned above, capable of being readily and selectively removed, and are not specifically defined. For example, those described in T. W. Greene, Protective Groups in Organic Synthesis, 3rd edition, Wiley, New York, 1999 may be used.
  • The intended compounds of the invention may be readily produced through selective use of the deprotecting reaction, which could be readily understood by anyone skilled in the art.
