Selective inhibition of cyclic AMP-dependent protein kinase by isoquinoline derivatives

A large series of isoquinoline derivatives was synthesised including derivatives of isoquinoline, isoquinolino[3,4-c]furazan, 1,2-dihydro-1-oxoisoquinoline, 6-oxopyrimido[1 ,2-b]isoquinoline, benzo[c][1,8]-naphthyridine, pyrazino[2,3-c]isoquinoline and benzimidazoe[2,1 -a]isoquinoline as well as further structurally related isoquinoline derivatives and pyrido-2,3-furazans. Representatives of all of these classes of isoquinolines are potent and selective inhibitors of the cyclic AMP-dependent protein kinase (PKA) catalytic subunit (cAK) from rat liver, The most effective cAK inhibitors are a series of 1,3-di-substituted and 1,3,4-tri-substituted isoquinolines (IC50 values 30 – 50 nM) (compounds A1, A2, A3, A4 and A5) and 2-ethylcarboxy-3-amino-5,6-dihydro-6-oxobenzo[c] [1 8]naphthyridine (El) (IC50 0.08 mu M) Compounds A1-A5 inhibit cAK in a fashion that is competitive with respect to ATP as substrate, The isoquinoline inhibitors A1-A5 are ineffective or very poor inhibitors of wheat embryo Ca2+-dependent protein kinase (CDPK) and rat brain Ca2+-dependent protein kinase C (PKC), chicken gizzard myosin light chain kinase (MLCK) and potato tuber cyclic nucleotide-binding phosphatase (Pase), E1 is a moderately effective inhibitor of CDPK and PKC (IC50 values 30 and 61 mu M, respectively), The bisisoquinoline-1 (2H)-one compound B7 inhibits cAK, CDPK, PKC and MLCK (IC50 values 8, 95, 24 and 7 mu M, respectively) as does J1 [2-(p-bromophenyl)pyrrolo[2,3-c]isoquinoline-5(4H)-one] (IC50 values 2, 50, 44 and 7 mu M, respectively), The very potent isoquinoline-derived cAK inhibitors found here involve substitution of the N-containing isoquinoline ring system and these inhibitors show high specificity for cAK.

Cytotoxic isoquinoline quinones from sponges of the genus Petrosia

Bioassay-guided fractionation of two Philippine sponges of the genus Petrosia has resulted in the isolation of the novel natural product cribrostatin 7 (1) and the known compounds renierone (2) and O-demethylrenierone (3). The structures of these isoquinoline quinones were determined by interpretation of spectroscopic data. Compounds 1, 2 and 3 were cytotoxic against the HCT 116 human colon carcinoma cell line with IC50 values of 45, 24 and 34 mug/mL, respectively.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 17557-76-5 is helpful to your research. HPLC of Formula: C14H12N2O4.

Total Syntheses of Telisatin A, Telisatin B and Lettowianthine

Treatment of 1-(2-bromoarylmethyl)-3,4-dihydroisoquinolines with oxalyl chloride and triethylamine gave 1-(2-bromophenyl)-5,6-dihydropyrrolo[2, 1-a]isoquinoline-2,3-dione derivatives, for example, 1-(2-bromophenyl)-5,6-dihydro-8,9-dimethoxypyrrolo[2, 1-a]isoquinoline-2,3-dione.

Synthesis and reactivity of some imidazo-, triazolo- and tetrazolo-isoquinoline derivatives

1-Acetylimino-3-methyl-1H-isochromene-4-carbonitrile, 1, reacts with glycine ethyl ester under basic conditions to give an imidazo[2,1-a]isoquinoline derivative, while reaction with hydrazine hydrate in 1,4-dioxane, with further chemistry, provides access to [1,2,4]triazolo[5,1-a]isoquinoline, [1,2,4]triazolo[3,4a]isoquinoline and tetrazolo[5,1-a]isoquinoline analogs. Benzene ring nitration and radical bromination of substituent methyl groups were investigated in the four tricycles, with some different positional reactivities being found. Two bromomethyl derivatives so produced were oxidised; ethyl 2-bromomethyl-6-cyano-5-methylimidazo[2,1-a]isoquinoline-3-carboxylate gave the anticipated ethyl 6-cyano-2-formyl-5-methylimidazo[2,1-a]isoquinoline-3-carboxylate (which reacted further with hydrazine to form a new system, 8,9-dihydro-6-methyl-8-oxopyridazino[4′,5′:4,5]imidazo[2,1-a]isoquinoline-5-carbonitrile), while 5-bromomethyl-2-methyl[1,2,4]triazolo[5,1-a]isoquinoline-6-carbonitrile unexpectedly gave directly another new system, 5,6-dihydro-5-hydroxy-2-methyl-7H-pyrrolo[3,4-c][1,2,4]triazolo[5,1-a]isoquinolin-7-one.

Synthesis of the new furo[3,2-h]isoquinoline alkaloid, TMC-120B from Aspergillus ustus

A total synthesis of a new furo[3,2-h]isoquinoline alkaloid TMC120-B (2), isolated from Aspergillus ustus together with two related compounds, has been completed in sixteen steps. The key step is the synthesis of the appropriate 3,7,8-trisubstituted isoquinoline framework (23) based on a thermal electrocyclic reaction of the 1-aza 6 pi-electron system involving the benzene double bond. In addition, the microwave assisted electrocyclic reaction of this system was newly performed.

Palladium-Catalyzed C-H Oxidation of Isoquinoline N-Oxides: Selective Alkylation with Dialkyl Sulfoxides and Halogenation with Dihalo sulfoxides

A novel palladium-catalyzed C?H oxidation of isoquinoline N-oxides has been developed for regioselectively synthesizing substituted isoquinolines. The method represents the first example of using dialkyl sulfoxides as the alkyl sources for the construction of 1-alkylated isoquinolines. Moreover, the regioselective halogenation of isoquinoline N-oxides is also successful using dihalo sulfoxides as the halide sources.

Direct 1,4-difunctionalization of isoquinoline

The synthesis of 1,4-disubstituted isoquinoline derivatives was achieved in one step starting from isoquinoline. The process involved a nucleophilic addition in 1-position followed by an electrophilic trapping in 4-position. Interesting features were noted when C2Cl6 was used as the electrophile since different compounds could be isolated selectively only by adjusting the reaction parameters. (C) 2009 Elsevier Ltd.
