Aminopyridyl/Pyrazinyl Spiro[indoline-3,4'-piperidine]-2-ones As Highly Selective and Efficacious c-Met/ALK Inhibitors.

ABSTRACT: A series of novel aminopyridyl/pyrazinyl-substituted spiro[indoline-3,4'-piperidine]-2-ones were designed, synthesized, and tested in various in vitro/in vivo pharmacological and antitumor assays. 6-[6-Amino-5-[(1R)-1-(2,6-dichloro-3-fluorophenyl)ethoxy]-3-pyridyl]-1'-methylspiro[indoline-3,4'-piperidine]-2-one (compound 5b or SMU-B) was identified as a potent, highly selective, well-tolerated, and orally efficacious c-Met/ALK dual inhibitor, which showed pharmacodynamics effect by inhibiting c-Met phosphorylation in vivo and significant tumor growth inhibitions (>50%) in GTL-16 human gastric carcinoma xenograft models.

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.

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.

Facile synthesis of functionalized spiro[indoline-3,2'-oxiran]-2-ones by Darzens reaction.

Project description:A series of functionalized spiro[indoline-3,2'-oxiran]-2-ones was efficiently synthesized by Darzens reaction of phenacyl bromides with isatins both with N-alkyl groups and without N-substituent in the presence of potassium carbonate as a base catalyst. When two equivalents phenacyl bromides were used in the reaction, the N-substitution reaction of isatin also finished with the formation of spiro-oxirane-oxindoles.

3',4'-Dihydro-2'H-spiro[indoline-3,1'-isoquinolin]-2-ones as potential anti-cancer agents: synthesis and preliminary screening.

Project description:Both tetrahydroisoquinolines (THIQs) and oxindoles (OXs) display a broad range of biological activities including anti-cancer activity, and are therefore recognized as two privileged scaffolds in drug discovery. In the present study, 24 3',4'-dihydro-2'H-spiro[indoline-3,1'-isoquinolin]-2-ones, designed as molecular hybrids of THIQ and OX, were synthesized and screened in vitro against 59 cell lines in the NCI-60 screen. Twenty compounds displayed weak to moderate inhibition of cell proliferation; among them, three compounds displayed at least 50% inhibition of cell proliferation. The compounds appeared to target primarily renal cell cancer lines; however, leukaemia, melanoma, non-small cell lung cancer, prostate, ovarian and even breast cancer cell lines were also affected. Therefore, this class of spirooxindoles may provide useful leads in the search for new anti-cancer agents.
