C3-arylated indazole and pyrazoles are privileged structural motifs in agrochemicals and pharmaceuticals. C-3 C-H arylation of (1H) indazole and pyrazole has been a significant challenge due to the poor reactivity of the C-3 position. Herein, we report a practical Pd(II)/Phen catalyst and conditions for direct C-3 arylation of indazole and pyrazole with ArI or ArBr without using Ag additives as...

In a previous study, we identified several structurally unrelated scaffolds of the Rho kinase inhibitor using pharmacophore information obtained from the results of a high-throughput screening and structural information from a homology model of Rho kinase. 1H-Indazole is one of the candidate scaffolds on which a new series of potent Rho kinase inhibitors could be developed. In this study, the d...

In the title compound, C(19)H(21)N(3)O(5)S·H(2)O, the central indazole system is essentially planar (r.m.s. deviation = 0.012 Å), while both the benzene ring and the mean plane defined by the non-H atoms of the ethyl propionic ester unit (r.m.s. deviation = 0.087 Å) are nearly perpendicular to the indazole plane, as indicated by the dihedral angles of 82.45 (8) and 75.62 (8)°, respectively. Con...

Recent drug discovery efforts are highly focused towards design and synthesis of small molecules of protein kinase C-β/AKt inhibitiors. 2 A wide ranges of heterocyclic ring systems has been studied for the development of novel chemical entities as lead molecules in the drug discovery paradigm. Indazole derivatives are one of the privileged structural fragments in medicinal chemistry having broa...

In the title compound, C16H14ClN3O4S, the six-membered ring of the indazole group is connected to a sulfonamide group. The indazole system is essentially planar, with the greatest deviation from the mean plane being 0.007 (2) Å. The dihedral angle between the two six-membered rings is 74.99 (9)°. The crystal structure exhibits inversion dimers in which mol-ecules are linked by pairs of N-H⋯O an...

A new series of spiropyrrolidine compounds containing indole/indazole moieties as side chains have been accomplished via a one-pot multicomponent synthesis. The method uses the 1,3-dipolar cycloaddition reaction between N-alkylvinylindole/indazole and azomethine ylides, prepared in situ from cyclic/acyclic amino acids. The 1,3-dipolar cycloaddition proceeds efficiently under thermal conditions ...

A series of 6-cyclic aliphatic amino-7-nitro-3,4-dihydroquinoline-2(1H)-ones were prepared and tested for platelet aggregation inhibitory effect, cardiotonic activity and chronotropic activity. These compounds appeared to show selective inhibitory activity against platelet aggregation. Among them, 6-(4-ethoxycarbonylpiperidino)-7-nitro-3,4-dihydroquinoline-2(1H)-one (22f) showed the most potent...

We disclose the development of a novel series of 2-phenyl-2H-indazole-7-carboxamides as poly(ADP-ribose)polymerase (PARP) 1 and 2 inhibitors. This series was optimized to improve enzyme and cellular activity, and the resulting PARP inhibitors display antiproliferation activities against BRCA-1 and BRCA-2 deficient cancer cells, with high selectivity over BRCA proficient cells. Extrahepatic oxid...

Tyrosine kinase fibroblast growth factor receptor (FGFR), which is aberrant in various cancer types, is a promising target for cancer therapy. Here we reported the design, synthesis, and biological evaluation of a new series of 6-(2,6-dichloro-3,5-dimethoxyphenyl)-4-substituted-1H-indazole derivatives as potent FGFR inhibitors. The compound 6-(2,6-dichloro-3,5-dimethoxyphenyl)-N-phenyl-1H-indaz...
