The poly(ADP-ribose)polymerases (PARPs) catalyse the transfer of ADP-ribose units from the substrate NAD+ to acceptor proteins, biosynthesising polyanionic poly(ADP-ribose) polymers. A major isoform, PARP-1, has been the target for design of inhibitors for over twenty-five years. Inhibitors of the activity of PARP-1 have been claimed to have applications in the treatment of many disease states, including cancer, haemorrhagic shock, cardiac infarct, stroke, diabetes, inflammation and retroviral infection, but only recently have PARP-1 inhibitors entered clinical trial. Most PARP-1 inhibitors mimic the nicotinamide of NAD+ and the structure-activity relationships are understood in terms of the structure of the catalytic site. However, five questions remain if PARP-1 inhibitors are to realise their potential in treating human diseases. Firstly, the consensus pharmacophore is a benzamide with N – H conformationally constrained anti to the carbonyl – arene bond but this is also a “pharmacophore” for insolubility in water; can water-solubility be designed into inhibitors without loss of potency? Secondly, some potential clinical applications require tissue-selective PARP-1 inhibition; is this possible through pro-drug approaches? Thirdly, different diseases may require therapeutic PARP-1 inhibition to be either short-term or chronic; are there potential problems associated with chronic inhibition of this DNA-repair process? Fourthly, PARP-1 is one of at least eighteen isoforms; is isoform-selectivity essential, desirable or even possible? Fifthly, PARP activity can be inhibited in cells by inhibition of poly(ADP-ribose)glycohydrolase (PARG); will this be a viable strategy for future drug design? The answers to these questions will determine the future of disease therapy through inhibition of PARP.

4-Methyl- and 4-benzyl-5-aminoisoquinolin-1-ones are close analogues of the water-soluble PARP-1 inhibitor 5-AIQ. Their synthesis was approached through Pd-catalysed cyclisations of N-(2-alkenyl)-2-iodo-3-nitrobenzamides. Reaction of N,N-diallyl-2-iodo-3-nitrobenzamide with Pd(PPh3)4 gave a mixture of 2-allyl-4-methyl-5-nitroisoquinolin-1-one and 2-allyl-4-methylene-5-nitro-3,4-dihydroisoquinolin-1-one. N-Benzhydryl-N-cinnamyl-2-iodo-3-nitrobenzamide similarly gave 2-benzhydryl-4-benzyl-5-nitroisoquinolin-1-one and 2-benzhydryl-4-benzylidene-5-nitro-3,4-dihydroisoquinolin-1-one. The isomeric products are not interconvertible. A deuterium-labelling study indicated that the isomers were formed by different pathways: a pi-allyl-Pd route and the classical Heck route. The corresponding secondary amides N-allyl-2-iodo-3-nitrobenzamide and N-((substituted)-cinnamyl)-2-iodo-3-nitrobenzamide gave good yields of the required 4-methyl- and 4-((substituted)-benzyl)-5-nitroisoquinolin-1-ones, respectively, under optimised conditions (Pd(PPh3)4, Et3N, Bu4NCl, 150 C, rapid heating). Hydrogenation of the nitro groups gave 4-methyl- and 4-benzyl-5-aminoisoquinolin-1-ones, which were potent inhibitors of PARP-1 activity.

A class of poly(ADP-ribose) polymerase (PARP-1) inhibitors, the imidazobenzodiazepines, are presented in this text. Several derivatives were designed and synthesized with ionizable groups (i.e., tertiary amines) in order to promote the desired pharmaceutical characteristics for administration in ischemic injury. Within this series, several compounds have excellent in vitro potency and our computational models accurately justify the structure-activity relationships (SARs) and highlight essential hydrogen bonding residues and hydrophobic pockets within the catalytic domain of PARP-1. Administration of these compounds (5q, 17a and 17e) in the mouse model of streptozotocin-induced diabetes results in maintainance of glucose levels. Furthermore, one such inhibitor (5g, IC50=26 nM) demonstrated significant reduction of infarct volume in the rat model of permanent focal cerebral ischemia.

Poly(ADP-ribose) polymerase (PARP), a nuclear enzyme activated by strand breaks in DNA, plays an important role in the tissue injury associated with inflammation. The aim of our study was to evaluate the therapeutic efficacy of in vivo inhibition of PARP in an experimental model of lung injury caused by bleomycin administration. Mice subjected to intratracheal administration of bleomycin developed significant lung injury and apoptosis (measured by Annexin V coloration). An increase of immunoreactivity to nitrotyrosine and PARP, as well as a significant loss of body weight and mortality, was observed in the lung of bleomycin-treated mice. Administration of the two PARP inhibitors 3-aminobenzamide (3-AB) or 5-aminoisoquinolinone (5-AIQ) significantly reduced the 1) loss of body weight, 2) mortality rate, 3) infiltration of the lung with polymorphonuclear neutrophils (myeloperoxidase activity), 4) edema formation, and 5) histological evidence of lung injury. Administration of 3-AB and 5-AIQ also markedly reduced nitrotyrosine formation and PARP activation. These results demonstrate that treatment with PARP inhibitors reduces the development of inflammation and tissue injury events induced by bleomycin administration in the mice. Copyright

Tankyrases, an enzyme subfamily of human poly(ADP-ribosyl)polymerases, are potential drug targets especially against cancer. We have evaluated inhibition of tankyrases by known PARP inhibitors and report five cocrystal structures of the most potent compounds in complex with human tankyrase 2. The inhibitors include the small general PARP inhibitors Phenanthridinone, PJ-34, and TIQ-A as well as the more advanced inhibitors EB-47 and rucaparib. The compounds anchor to the nicotinamide subsite of tankyrase 2. Crystal structures reveal flexibility of the ligand binding site with implications for drug development against tankyrases and other ADP-ribosyltransferases. EB-47 mimics the substrate NAD+ and extends from the nicotinamide to the adenosine subsite. The clinical ARTD1 inhibitor candidate rucaparib was the most potent tankyrase inhibitor identified (24 and 14 nM for tankyrases), which indicates that inhibition of tankyrases would affect the cellular responses of this compound.

Poly(ADP-ribose)polymerase-1 (PARP-1) is an important target for drug design for several therapeutic applications. 5-Aminoisoquinolin-1-one (5-AIQ) is a highly water-soluble lead compound; synthetic routes to 3-substituted analogues were explored. Tandem Hurtley coupling of beta-diketones with 2-bromo-3-nitrobenzoic acid, retro-Claisen acyl cleavage and cyclisation gave the corresponding 3-substituted 5-nitroisocoumarins. Treatment with ammonia at high temperature and reduction with tin(II) chloride gave eleven target 3-substituted 5-AIQs, which were all soluble in water (>1% w/v) as their HCl salts. Most were more potent than 5-AIQ as inhibitors of PARP-1 and of PARP-2 in vitro, the most active being 5-amino-3-methylisoquinolin-1-one (PARP-1: IC 50 = 0.23 muM vs IC50 = 1.6 muM for 5-AIQ). Some rationalisation of the SAR was achieved through molecular modelling.
