Study of Some Bidentate Schiff Bases of Isatin as Corrosion Inhibitors for Mild Steel in Hydrochloric Acid Solution

International Journal of Electrochemical Science, 2012
The effect of Schiff base compounds, namely, ethylenediamine bis-isatin (EDBI), hexane 1,4-diamine bis-isatin (HDBI) and thiocarbohydrazide bis-isatin (TCBI) were investigated by gravimetric, potentiodynamic polarization, electrochemical impedance ...

Condensation of Indole with Isatin over AlCl₃/Mesoporous Aluminosilicate

Indonesian Journal of Chemistry, 2015
Aluminium chloride immobilized on mesoporous aluminosilicate was investigated as catalysts in the condensation of isatin with indole. AlCl3/mesoporous aluminosilicate (AlCl3/AM) catalysts were prepared by impregnation of 1, 5, 10 and 15 wt% AlCl3 on the ...

ELECTROLYTIC REDUCTION OF ISATIN AND ITS DERIVATIVES. Ⅱ.: REDUCTION OF N-METHYL ISATIN [PDF]

N-methyl-isatin can be reduced by the same process as in the case of isatin only by controlling the conditions as follows: (1) It is reduced to N-methyl-dioxyindol with lead cathode suspended in 20% dilute sulphuric acid solution.

N-Alkyl-Substituted Isatins Enhance P2X7 Receptor-Induced Interleukin-1β Release from Murine Macrophages

Mediators of Inflammation, 2016
Extracellular adenosine 5′-triphosphate (ATP) activates the P2X7 receptor channel to induce the rapid release of the proinflammatory cytokine, interleukin- (IL-) 1β, from macrophages. Microtubule rearrangements are thought to be involved in this process.

Molecular docking and synthesis of N-alkyl-isatin-3-imino aromatic amine derivatives and their antileishmanial and cytotoxic activities

Research in Pharmaceutical Sciences
Background and purpose: Isatin derivatives have excited attention due to their biological attractions, especially, anticancer properties. Isatin analogs such as semaxanib and sunitinib were exposed to tyrosine kinase inhibitory properties.

Thiazolidinedione–Isatin Conjugates via an Uncatalyzed Diastereoselective Aldol Reaction on Water

, 2014
An uncatalyzed aldol reaction of N-substituted thiazolidinediones with isatin derivatives has been developed "on water" to afford a new class of pharmacologically important thiazolidinedione-isatin conjugates in excellent yields and ...

Evaluation of the Antibacterial Activity of Isatin against Campylobacter jejuni and Campylobacter coli Strains

Applied Microbiology
Antibiotic resistance, particularly against fluoroquinolones and macrolides, has emerged globally among thermophilic Campylobacters (Campylobacter jejuni and Campylobacter coli), giving rise to concerns about the efficacy of antibiotic treatment of these

THE SYNTHESIS OF NEW SPIROLACTONES FROM SUBSTITUTED ISATINS [PDF]

Chemistry Journal of Moldova: General, Industrial and Ecological Chemistry, 2015
Interaction of N-ethyl isatin 3 with dimethyl acetylenedicarboxylate in the presence triphenylphosphine has led to good selectivity of methyl 1'-ethyl-4-methoxy-2',5-dioxo-5H-spiro[furan-2,3'-indoline]-3-carboxylate 4 formation.
