DESCRIPTION
FUSED PYRIDAZINE DERIVATIVE COMPOUNDS AND
DRUGS CONTAINING THESE COMPOUNDS AS THE ACTIVE INGREDIENT
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) (RY) ay m yon he
A
(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"
Lereinafer) *c varicus proteins such as histones, DNA-polymerases and DNA- topoisomerases, erc.
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-13-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 efc.), diabetes, shock, extrapyramidal disease (7IPS., 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 efc.), inflammatory diseases (inflammatory bowel disease, multiple sclerosis, arthritis or lung injury efc.), 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.
As PARP inhibitor, for example, in the specification of W000/44726, it is described that 2H-phthalazin-1-one derivatives represented by formula (A) 0
