In the title compound, C(16)H(13)N(5)O(3)S·CH(4)O, the dihedral angle between the isatin unit and the 2-methyl-phenyl group is 41.81 (2)° and intra-molecular N-H⋯O and N-H⋯N hydrogen bonds occur, generating S(6) and S(5) rings, respectively. In the crystal, polymeric chains arise as a result of N-H⋯O, O-H⋯S and C-H⋯O inter-actions.

Fe-MIL-101-isatin-Schiff-base-Co was synthesized and applied as a catalyst for Ullmann-type, Buchwald–Hartwig, Hirao, Hiyama Mizoroki–Heck cross-coupling reactions of aryl halides.

The title compound, C(19)H(18)N(4)O(3) [systematic name: (RS)-1-benzyl-3-hy-droxy-3-(2-imino-3-methyl-5-oxoimidazolidin-4-yl)-2,3-dihydro-1H-indol-2-one], was prepared as a racemate (RR and SS) by the aldol condensation of N-benzyl-isatin with creatinine in the presence of sodium acetate in acetic acid. The r.m.s. deviation of the isatin ring system is 0.033 Å. The benzyl group is disordered ov...

Nowadays, cancer is one of the main reasons of death between nations caused by different elements such as presence of mutagenic and cancer causing materials in the environment. Isatin and Carbon nanotubes can be used to deliver their cargoes to cells and organs. The potential use of them to treat several types of cancer, with minimal or no toxic effects to normal cells. In the present study, 1,...

In the present work, some new 5-[2(3)-dialkylamino alkoxy] Indole 2, 3-diones were prepared from 5-hydroxy isatin. A mixture of 5-hydroxy isatin, dialkylamino alkylhalide in alcoholic potassium hydroxide was stirred at room temperature for 6 hours to get the 5-[2(3)dialkylamino alkoxy] Indole 2,3-diones. The structures of the products were characterized by IR, NMR, MASS Spectral studies. All th...

In the title compound, C(16)H(13)ClN(4)OS, the isatin ring system is oriented at dihedral angles of 10.60 (7) and 72.60 (3)° with respect to the thio-semicarbazide and 2-chloro-benzyl groups, respectively. The near planarity of the isatin and thio-semicarbazide groups [r.m.s. deviations of 0.0420 and 0.0163 Å, respectively] is reinforced by intra-molecular N-H⋯O and N-H⋯N hydrogen bonds, which ...

The aim of the present study is to synthesize the oxovanadium complex of the V3+ ion with isatin sciff bases. Spectroscopic methods have been used to confirm these models of complexation and to understand the structures of the species formed in methanolic solution. We also have isolated a complex of Vanadium (III) with isatin schiff bases in the solid phase.

We have recently identified a new class of compounds that selectively kill cells that express P-glycoprotein (P-gp, MDR1), the ATPase efflux pump that confers multidrug resistance on cancer cells. Several isatin-beta-thiosemicarbazones from our initial study have been validated and a range of analogues synthesized and tested. A number demonstrated improved MDR1-selective activity over the lead,...
