The reaction of 2-(2-phenylethynyl)aniline with acetone in presence of [IrCp*Cl(2)](2) has previously been found to yield a vinyl indole derivative and not the indole expected to form following a hydroamination reaction. Experimental data, including labelling studies, isolation and solid state structure determination of a reaction intermediate together with DFT calculations were used to develop...

In spinocerebellar ataxia type 17 (SCA17), the expansion of a translated CAG repeat in the TATA box binding protein (TBP) gene results in a long polyglutamine (polyQ) tract in the TBP protein, leading to intracellular accumulation of aggregated TBP and cell death. The molecular chaperones act in preventing protein aggregation to ameliorate downstream harmful events. In this study, we used Tet-O...

An indole hydrazone has successfully been synthesized employing Schiff base reaction conditions starting from 4,6-dimethoxy-2,3-diphenylindole-7-carbaldehyde with hydrazine hydrate. The of this compound acetone yielded based imine compound. structure targeted was identified by mass and 1H spectroscopy along single crystal X-ray diffraction technique. Also, bromination bis-indole N-bromo succini...

A series of indole-based aryl(aroyl)hydrazone analogs of antiplatelet indole-3-carboxaldehyde phenylhydrazone were synthesized by the Schiff base formation reaction and their antiplatelet activity was assessed using human platelet rich plasma. The platelet concentrate was obtained using a two-step centrifugation protocol and ADP, arachidonic acid and collagen were used as inducers of platelet a...

In the title indole derivative, C22H21NO4, the dihedral angle between the benzene and pyrrole rings of indole moiety is 1.8 (1)°. The plane of the 4-meth-oxy-phenyl ring is oriented with a dihedral angle of 60.7 (1)° with respect to the plane of the indole moiety. The mol-ecular packing is stabilized by C-H⋯O hydrogen bonds which form a V-shaped chain arrangement along the bc plane of the unit ...

The title compound, C(12)H(13)NO(4), was prepared as a precursor to an indole derivative with possible anti-mitotic properties. The mol-ecule is very nearly planar; the maximum deviation of any non-H atom from the mean plane of the indole ring is 0.120 (3) Å for each of two meth-oxy C atoms. The pairs of mol-ecules related by the inversion centre at (0,0,) are connected by two symmetry-equivale...

In the title indole derivative, C20H18ClNO2, the chloro-phenyl ring is almost perpendicular to the indole moiety, making a dihedral angle of 87.6 (1)°. The mol-ecular packing is stabilized by C-H⋯π inter-actions, which form a C(9) chain motif along [10-1]. In addition, there are weak π-π inter-actions [centroid-centroid distance 3.851 (1) Å] between the chains, involving inversion-related chlor...
