چکیده
The structure of the title compound, C11H7NO2, is isotypic to that of its homologue, 1-octylindoline-2,3-dione [Qachchachi et al. (2013 ▶). Acta Cryst. E69, o1801]. The indoline ring and the two carbonyl O atoms are approximately coplanar, the largest deviation from the mean plane being 0.021 (1) Å for one of the O atoms. The mean plane through the fused ring system is nearly perpendicular to the propynyl group, as indicated by the N-C-C-C torsion angle of 77.9 (1)°. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds and π-π inter-actions between benzene rings [inter-centroid distance = 3.5630 (10) Å], forming a three-dimensional structure.

The mol-ecule of the title compound, C(18)H(12)N(2)O(4), is situated on a crystallographic centre of symmetry. The mol-ecule has a zigzag structure, with two parallel symmetry-related indoline-2,3-dione fragments linked by an ethyl-ene group at each N atom. In the crystal, the mol-ecules stack in columns along the b axis. There are two such columns in the structure. The mol-ecules within each c...

There are two independent mol-ecules in the asymmetric unit of the title compound, C10H8INO2, which differ in the degree of planarity. The iodo-indoline-2,3-dione skeleton of mol-ecule 1 is essentially planar [mean deviation = 0.003 (2) Å for the nine non-H atoms of the indoline core, with a maximum deviation of 0.033 (1) Å for the I atom]. The I atom and O atom in the 3-position of mol-ecule 2...

In the present study a series of Schiff bases of indoline-2,3-dione were synthesized and investigated for their Mtb gyrase inhibitory activity. Promising inhibitory activity was demonstrated with some of these derivatives, which exhibited IC(50) values ranging from 50-157 mM. The orientation and the ligand-receptor interactions of such molecules within the Mtb DNA gyrase A subunit active site w...
متن کاملSynthesis and biological evaluation of novel indoline-2,3-dione derivatives as antitumor agents.
A new series of 1,5-disubstituted indolin-2,3-diones was synthesized and their inhibition of the growth of a human acute promyelocytic leukemia (HL-60) cell line was evaluated. These compounds had promising inhibition of HL-60 cell growth in vitro. Results indicated that compounds with a benzyl substituent at the N-1 position on the indolin-2,3-dione ring had more potent antiproliferative activ...
