This review highlights the promising science that has arisen from the synthesis of novel azaheterocycles from isocoumarins. Specific topics include their synthesis and biological activity. Isocoumarins (1H-isochromen-1-ones) are promising synthons, in particular due to the presence of a deoxybenzoin fragment which opens up wide possibilities for synthetic transformations. The deoxybenzoin cycle is highly susceptible to the action of various nucleophilic agents; its oxygen atom participates in recyclization reactions under the action of N-nucleophiles where it is replaced by a nitrogen atom, making it possible to obtain isoquinolones via a reaction with ammonia, primary amines, hydroxylamine and benzodiazepinones via a reaction with hydrazine. We systematize literature data, including patents (about 60 publications in all), demonstrate the routes of 3-arylisocoumarins modification under the action of N-nucleophiles ? ammonia and primary amines, diamines, secondary amines, (het)arylamines, hydroxylamine, and hydrazines, and discuss the practical importance of these studies for medicinal chemistry.

Poly (ADP-ribose) polymerase (PARP), a nuclear enzyme activated by strand breaks in DNA, plays an important role in the colon injury associated with experimental colitis. The aim of the present study was to examine the effects of 5-aminoisoquinolinone (5-AIQ), a novel and potent inhibitor of PARP activity, in the development of experimental colitis. To address this question, we used an experimental model of colitis, induced by dinitrobenzene sulfonic acid (DNBS). Compared with DNBS-treated mice, mice treated with 5-AIQ (3 mg/kg i.p.) or 3-aminobenzamide (3-AB; 10 mg/kg i.p. twice a day) and subjected to DNBS-induced colitis experienced a significantly lower rate in the extent and severity of the histological signs of colon injury. DNBS-treated mice experienced diarrhea and weight loss. Four days after administration of DNBS, the mucosa of the colon exhibited large areas of necrosis. Neutrophil infiltration (determined by histology as well as an increase in myeloperoxidase [MPO] activity in the mucosa) was associated with an up-regulation of intercellular adhesion molecule-1 (ICAM-1). Immunohistochemistry for PAR showed an intense staining in the inflamed colon. On the contrary, the treatment of DNBS-treated mice with 5-AIQ or with 3-AB significantly reduced the degree of hemorrhagic diarrhea and weight loss caused by administration of DNBS. 5-AIQ also caused a substantial reduction in the degree of colon injury, in the rise in MPO activity (mucosa), in the increase in staining (immunohistochemistry) for PAR, as well as in the up-regulation of ICAM-1 caused by DNBS in the colon. Thus, 5-AIQ treatment reduces the degree of colitis caused by DNBS. We propose that 5-AIQ treatment may be useful in the treatment of inflammatory bowel disease. Springer-Verlag 2004.

93117-08-9, Name is 5-Aminoisoquinolin-1(2H)-one, belongs to isoquinoline compound, is a common compound. category: isoquinolineIn an article, once mentioned the new application about 93117-08-9.

Poly(ADP-ribose)polymerase-1 is an important target enzyme in drug design; inhibitors have a wide variety of therapeutic activities. A series of quinoline-8-carboxamides was designed to maintain the required pharmacophore conformation through an intramolecular hydrogen bond. 3-Substituted quinoline-8-carboxamides were synthesized by Pd-catalyzed couplings (Suzuki, Sonogashira, Stille) to 3-iodoquinoline-8-carboxamide, an efficient process that introduces diversity in the final step. 2-Substituted quinoline-8-carboxamides were prepared by selective Pd-catalyzed couplings at the 2-position of 2,8-dibromoquinoline, followed by lithium-bromine exchange of the intermediate 2-(alkyl/aryl)-8-bromoquinolines and reaction with trimethylsilyl isocyanate. The intramolecular hydrogen bond was confirmed by X-ray and by NMR. The SAR of the 3-substituted compounds for inhibition of human recombinant PARP-1 activity showed a requirement for a small narrow group. Substituents in the 2-position increased potency, with the most active 2-methylquinoline-8-carboxamide having IC50 = 500 nM (IC50 = 1.8 muM for 5-aminoisoquinolin-1- one (5-AIQ, a standard water-soluble inhibitor)).

Effects of 5-aminoisoquinolinone, a water-soluble, potent inhibitor of the activity of poly (ADP-ribose) polymerase, in a rodent model of lung injury

Poly (ADP-ribose) polymerase (PARP), a nuclear enzyme activated by strand breaks in DNA, plays an important role in the tissue injury associated with ischaemia-reperfusion injury and inflammation. The aim of the present study was to evaluate the effects of a novel and potent inhibitor of PARP activity on neutrophil recruitment in the acute inflammation induced by zymosan-activated plasma. Intra-thoracic administration of zymosan-activated plasma leads to an increase in neutrophil infiltration of the lung at 24 hr. The potent PARP inhibitor 5-aminoisoquinolinone (5-AIQ) reduced the degree of lung injury and attenuated the expression of P-selectin and ICAM-1 as well as the recruitment of neutrophils into the injured lung. The up-regulation/expression of P-selectin and ICAM-1 in human endothelial cells exposed to oxidative stress (peroxynitrite) or to a pro-inflammatory cytokine (tumor necrosis factor alpha, TNFalpha) was also attenuated by 5-AIQ. These findings provide the first evidence that the activation of PARS participates in neutrophil-mediated lung injury by regulating the expression of P-selectin and ICAM-1.

5-benzamidoisoquinolin-1-ones and 5-(omega-Carboxyalkyl)isoquinolin-1- ones as isoform-selective inhibitors of poly(ADP-ribose) polymerase 2 (PARP-2)

PARP-2 is a member of the poly(ADP-ribose) polymerase family, with some activities similar to those of PARP-1 but with other distinct roles. Two series of isoquinolin-1-ones were designed, synthesized, and evaluated as selective inhibitors of PARP-2, using the structures of the catalytic sites of the isoforms. A new efficient synthesis of 5-aminoisoquinolin-1-one was developed, and acylation with acyl chlorides gave 5-acylaminoisoquinolin-1-ones. By examination of isoquinolin-1-ones with carboxylates tethered to the 5-position, Heck coupling of 5-iodoisoquinolin-1-one furnished the 5-CH – CHCO2H compound for reduction to the 5-propanoic acid. Alkylation of 5-aminoisoquinolin-1-one under mildly basic conditions, followed by hydrolysis, gave 5-(carboxymethylamino)isoquinolin-1-one, whereas it was alkylated at 2-N with methyl propenoate and strong base. Compounds were assayed in vitro for inhibition of PARP-1 and PARP-2, using FlashPlate and solution-phase assays, respectively. The 5-benzamidoisoquinolin-1-ones were more selective for inhibition of PARP-2, whereas the 5-(?-carboxyalkyl)isoquinolin-1-ones were less so. 5-Benzamidoisoquinolin-1-one is the most PARP-2-selective compound (IC50(PARP-1)/IC50(PARP-2) = 9.3) to date, in a comparative study.

Inhibition of matrix metalloproteinase-2 by PARP inhibitors

Matrix metalloproteinase-2 (MMP-2), a ubiquitously expressed zinc-dependent endopeptidase, and poly(ADP-ribosyl) polymerase (PARP), a nuclear enzyme regulating DNA repair, are activated by nitroxidative stress associated with various pathologies. As MMP-2 plays a detrimental role in heart injuries resulting from enhanced nitroxidative stress, where PARP and MMP inhibitors are beneficial, we hypothesized that PARP inhibitors may affect MMP-2 activity. Using substrate degradation assays to determine MMP-2 activity we found that four PARP inhibitors (3-AB, PJ-34, 5-AIQ, and EB-47) inhibited 64 kDa MMP-2 in a concentration-dependent manner. The IC50 values of PJ-34 and 5-AIQ were in the high micromolar range and comparable to those of known MMP-2 inhibitors doxycycline, minocycline or o-phenanthroline, whereas those for 3-AB and EB-47 were in the millimolar range. Co-incubation of PARP inhibitors with doxycycline showed an additive inhibition of MMP-2 that was significant for 3-AB alone. These data demonstrate that the protective effects of some PARP inhibitors may include inhibition of MMP-2 activity.
