4-Substituted 5-nitroisoquinolin-1-ones from intramolecular Pd-catalysed reaction of N-(2-alkenyl)-2-halo-3-nitrobenzamides

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 pie-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 degree 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

Developing structure-activity relationships from an HTS hit for inhibition of the Cks1-Skp2 protein-protein interaction

Structure-activity relationships have been developed around 5-bromo-8-toluylsulfonamidoquinoline 1 a hit compound in an assay for the interaction of the E3 ligase Skp2 with Cks1, part of the SCF ligase complex. Disruption of this protein-protein interaction results in higher levels of CDK inhibitor p27, which can act as a tumor suppressor. The results of the SAR developed highlight the relationship between the sulfonamide and quinoline nitrogen, while also suggesting that an aryl substituent at the 5-position of the quinoline ring contributes to the potency in the interaction assay. Compounds showing potency in the interaction assay result in greater levels of p27 and have been shown to inhibit cell growth of two p27 sensitive tumor cell lines.

Studies on anti-Helicobacter pylori agents. Part 1: Benzyloxyisoquinoline derivatives

The synthesis and optimization of the anti-Helicobacter pylori activity of a novel series of benzyloxyisoquinoline derivatives that was discovered by a random screening process, are described. In the in vitro assay, compound 10c containing a 3-acetamido-2,6-dichlorobenzyl substituent was found to have extremely potent activity against H. pylori and no activity against other common bacteria. The anti-H. pylori activity of 10c was superior to that of amoxicillin (AMPC) (1) and clarithromycin (CAM) (2). However, 10c did not show in vivo efficacy in a mouse infection model; a feature attributed to the lack of strong bactericidal activity at short contact times. (C) 1999 Elsevier Science Ltd.

A novel high-efficiency white hyperbranched polymer derived from polyfluorene with green and red iridium(III) complexes as the cores

A new kind of single triple-color hyperbranched polymer PF-Ir(ppy)2(pytzph)m-Ir(piq)2(pytzph)n was designed and synthesized, in which green and red iridium(III) complexes acted as cores and blue polyfluorene acted as backbone. PF-Ir(ppy)2(pytzph)m-Ir(piq)2(pytzph)n (m = 5, n = 5 and m = 25, n = 5) had higher quantum efficiency than PF-Ir(piq)2(pytzph)5. The energy transfer from green core bis(2-phenylpyridine)[3-(2-pyridyl)-5-phenyl-1,2,4-triazole]iridium(III) [Ir(ppy)2(pytzph)] with high triplet energy level (ET = 2.58 eV) to red core bis(1-phenylisoquinolinato)[3-(2-pyridyl)-5-phenyl-1,2,4-triazole]iridium(III) [Ir(piq)2(pytzph)] (ET = 2.12 eV) could realize by intermediate poly(9,9-dioctylfluorene) (PF) segments. A typical single emitting-layer device with the configuration of ITO/PEDOT:PSS (40 nm)/PF-Ir(ppy)2(pytzph)m-Ir(piq)2(pytzph)n (80 nm)/TPBi (40 nm)/LiF (0.8 nm)/Al (100 nm) was fabricated. Among the white polymers, PF-Ir(ppy)2(pytzph)5-Ir(piq)2(pytzph)5 exhibited excellent electroluminescent properties with a Commission Internationale Ed I’eclairage (CIE) coordinate of (0.32, 0.34) and a maximum luminous efficiency of 11.49 cd/A.

3,7-Disubstituted-1,2,3,4-tetrahydroisoquinolines display remarkable potency and selectivity as inhibitors of phenylethanolamine N- methyltransferase versus the alpha2-adrenoceptor(1a)

3-Hydroxymethyl-1,2,3,4-tetrahydroisoquinoline (4) is a more selective inhibitor (PNMT K(i) = 1.1 muM, alpha2 K(i) = 6.6 muM, selectivity (alpha2 K(i)/PNMT K(i)) = 6.0) of phenylethanolamine N-methyltransferase (PNMT, EC 2.1.1.28), with respect to its alpha2-adrenoceptor affinity, than is 3-methyl- 1,2,3,4-tetrahydroisoquinoline (2; PNMT K(i) = 2.1muM, alpha2 K(i) = 0.76 muM, selectivity = 0.36) or 1,2,3,4-tetrahydroisoquinoline (1, THIQ; PNMT K(i) = 9.7 muM, alpha2 K(i) = 0.35 muM, selectivity = 0.036). Evaluation of the O- methyl ether derivative of 4 suggested that the 3-hydroxymethyl substituent might be involved in a hydrogen-bond donor-type of interaction at a sterically compact region in the PNMT active site. The directionality of the steric bulk tolerance at both the PNMT active site and the alpha2-adrenoceptor appears to be the same. Since the presence of a hydrophilic electron- withdrawing substituent (such as NO2, SO2CH3, or SO2NH2) at the 7- position of THIQ reduced the binding affinity toward the alpha2-adrenoceptor, we investigated the combination of both a hydrophilic electron-withdrawing 7- substituent and a 3-alkyl substituent on a THIQ nucleus. A synergistic effect in increasing the PNMT-inhibitory potency of the THIQ nucleus and reducing the affinity toward the alpha2-adrenoceptor was observed with this 3,7- disubstitution. Remarkably, 7-aminosulfonyl-3-hydroxymethyl-THIQ (12; PNMT K(i) = 0.34 muM, alpha2 K(i) = 1400 muM, selectivity = 4100) displayed a 23- 680-fold enhanced selectivity over the parent compounds 27 (SK and F 29661; PNMT K(i) = 0.55 muM, alpha2 K(i) = 100 muM, selectivity = 180) and 4 selectivity = 6.0) and is thus the most selective PNMT inhibitor yet reported.

Sterically Encumbered Tetraarylimidazolium Carbene Pd-PEPPSI Complexes: Highly Efficient Direct Arylation of Imidazoles with Aryl Bromides under Aerobic Conditions

A series of sterically encumbered tetraarylimidazolium carbene Pd-PEPPSI complexes were conveniently prepared and fully characterized. These sterically encumbered Pd-PEPPSI complexes act as active precatalysts for the direct arylation of imidazoles with aryl bromides under aerobic conditions. The catalytic performance of Pd-PEPPSI complexes in cross-coupling processes is investigated. Under the optimal protocols, the cross-coupling reactions regioselectively produced C5-arylation products in moderate to excellent yields, which could tolerate a wide range of functional aryl bromides.
