Optimization of indirubin and indigo production in E.coli [PDF]

open access: yes, 2015
The goal of this thesis is to determine the conditions that give the highest yield of indigo and indirubin in recombinant E.coli. This E.coli has been transformed with a P450 gene from woad, an indigo producing plant. The conditions investigated were the

Spectroscopic studies on Isatin-3-Semicarbazone and Isatin-3-Thiosemicarbazone

open access: yesGlobal Journal of Pure and Applied Sciences, 2004
The configurations of semi-and thiosemicarbazone derivatives of isatin are assigned by means of 1H and 13C NMR Spectroscopy including NOE difference spectra, IR and electronic spectral data of these compounds are also reported and discussed. The electron impact (EI), fast atom bombardment (FAB) and negative ion chemical ionization (NICI) mass spectra ...

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

open access: yesMediators 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.

Asymmetric vinylogous Mukaiyama aldol reaction of isatins under bifunctional organocatalysis: Enantioselective synthesis of substituted 3-hydroxy-2-oxindoles [PDF]

open access: yes, 2018
A highly enantioselective organocatalytic vinylogous Mukaiyama aldol reaction of silyloxy dienes and isatins under bifunctional organocatalysis is presented. Substituted 3-hydroxy-2-oxindoles are synthesised in good yields and enantioselectivities. These

Design, synthesis and anticonvulsant activity of some new 5,7-dibromoisatin semicarbazone derivatives [PDF]

open access: yes, 2013
A series of 5,7-dibromoisatin semicarbazones have been synthesized in good yield, involving aryl urea and aryl semicarbazide formation. The structures of the synthesized compounds were confirmed on the basis of their spectral data. All the compounds were
