ABSTRACT: In the title compound C(37)H(32)Cl(2)N(2)O(4), the unsubstituted pyrrolidine ring shows a twist conformation whereas the substituted pyrrolidine ring shows an envelope conformation. The dimeth-oxy benzene ring is perpendicular to the tetra-lone ring, making a dihedral angle of 89.94?(5)°. Mol-ecules are linked into centrosymmetric dimers by N-H?O hydrogen bonds and the crystal structure is stabilized by C-H?? inter-actions and C-H?O hydrogen bonds. One meth-oxy group is disordered over two positions with the site occupancy factors of 0.84?(2) and 0.16?(2).

Synthesis of functionalized spiro[indoline-3,4'-pyridines] and spiro[indoline-3,4'-pyridinones] via one-pot four-component reactions.

Project description:In the presence of triethylamine as catalyst, the one-pot four-component reactions of arylamines, methyl propiolate, isatin and malononitrile afforded the functionalized spiro[indoline-3,4'-pyridine] derivatives in good yields. Similar reactions with ethyl cyanoacetate successfully afforded the functionalized spiro[indoline-3,4'-pyridines] and spiro[indoline-3,4'-pyridinones] as the main products according to the structures of the arylamines and other primary amines.

Novel Functionalized Spiro [Indoline-3,5'-pyrroline]-2,2'dione Derivatives: Synthesis, Characterization, Drug-Likeness, ADME, and Anticancer Potential.

Project description:A highly stereo-selective, one-pot, multicomponent method was chosen to synthesize the novel functionalized 1, 3-cycloaddition spirooxindoles (SOXs) (4a-4h). Synthesized SOXs were analyzed for their drug-likeness and ADME parameters and screened for their anticancer activity. Our molecular docking analysis revealed that among all derivatives of SOXs (4a-4h), 4a has a substantial binding affinity (∆G) -6.65, -6.55, -8.73, and -7.27 Kcal/mol with CD-44, EGFR, AKR1D1, and HER-2, respectively. A functional study demonstrated that SOX 4a has a substantial impact on human cancer cell phenotypes exhibiting abnormality in cytoplasmic and nuclear architecture as well as granule formation leading to cell death. SOX 4a treatment robustly induced reactive oxygen species (ROS) generation in cancer cells as observed by enhanced DCFH-DA signals. Overall, our results suggest that SOX (4a) targets CD-44, EGFR, AKR1D1, and HER-2 and induces ROS generation in cancer cells. We conclude that SOX (4a) could be explored as a potential chemotherapeutic molecule against various cancers in appropriate pre-clinical in vitro and in vivo model systems.

3',7',7'-Trimethyl-1'-phenyl-5',6',7',8'-tetra-hydro-spiro-[indoline-3,4'-(1H,4H-pyrazolo-[3,4-b]chromene)]-2,5'-dione.

Project description:The title spiro-oxindole compound, C(26)H(23)N(3)O(3), was prepared by the reaction of isatin, 3-methyl-1-phenyl-2-pyrazolin-5-one and 5,5-dimethyl-cyclo-hexane-1,3-dione in an ethanol solution. The fused cyclo-hexene ring adopts an envelope conformation. The dihedral angle between the aromatic and pyrazoline rings is 23.70?(8)°. An intra-molecular C-H?O inter-action occurs. The crystal structure is stabilized by N-H?N hydrogen-bonding inter-actions, leading to a zigzag chain along the b axis.

1-Benzyl-4',5'-diphenyl-piperidine-3-spiro-3'-pyrrolidine-2'-spiro-3''-indoline-4,2''-dione.

Project description:The asymmetric unit of the title compound, C(34)H(31)N(3)O(2), consists of two independent mol-ecules which differ slightly in the orientations of the phenyl rings with respect to the pyrrolidine ring. In both mol-ecules, the piperidin-4-one ring adopts a chair conformation, whereas the pyrrolidine ring adopts an envelope conformation in one of the mol-ecules and a twisted conformation in the other. An intra-molecular C-H?O hydrogen bond is observed. The crystal packing is stabilized by inter-molecular N-H?O hydrogen bonds and C-H?? inter-actions.

5,6-Dimeth-oxy-4',5'-diphenyl-indane-2-spiro-3'-pyrrolidine-2'-spiro-3''-indoline-1,2''-dione.

Project description:In the title compound, C(33)H(28)N(2)O(4), the central pyrrolidine ring adopts a half-chair conformation. Both the indolinone and indanone groups are twisted, with their five-membered rings adopting a half-chair and an envelope conformation, respectively.

Intra-molecular C-H⋯O hydrogen bonds stabilize the mol-ecular conformation. In the crystal, pairs of inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers. The dimers are inter-connected into ribbons propagating along [110] via weak inter-molecular C-H⋯O hydrogen bonds. Weak inter-molecular C-H⋯π and π-π [centroid-centroid distance = 3.6509 (11) Å] inter-actions are also observed.
