Activation of the NC-H bond of Baylis-Hillman adducts of N-methylisatin with CAN/ROH

A facile method for activation of the NC-H bond of N-methylisatin and Baylis-Hillman adducts of N-methylisatin with cerium ammonium nitrate (CAN) and saturated and unsaturated alcohols is reported. Adducts bearing an ester group at the activated alkene afford functionalized ethers, while those with a nitrile afforded ethers and nitrated aromatic products in good yield.

Synthesis and in vitro cytotoxicity evaluation of isatin-pyrrole derivatives against HepG2 cell line

This paper reports the synthesis and in vitro cytotoxicity evaluation of isatin-pyrrole derivatives 5-8, obtained from the appropriate isatins with pyrrole, with good yields and purity. The product structures were confirmed through spectroscopy methods. Furthermore, the MTT assay on the human liver cancer HepG2 cell lines revealed moderate activity in all compounds, which was highest in sample 6 (IC50 0.47 μM). The anticancer activity was affiliated with the presence of a nitro group at C-5 and N-methyl of the isatin scaffold.

Synthesis of new spiroindolinones incorporating a benzothiazole moiety as antioxidant agents

3H-Spiro[1,3-benzothiazole-2,3′-indol]-2′(1′H)-ones 3a-c and 4a-e were synthesized from treating the 5-substituted 1H-indole-2,3-diones with 2-aminothiophenol in ethanol. The structures were confirmed by elemental analyses, spectrometry (IR, 1H NMR, 13C NMR, HSQC-2D and LCMS-APCI) and single crystal X-ray analysis. The new compounds were screened for their antioxidant activities such as the Fe3+/ascorbate system induced inhibition of lipid peroxidation (LP) in liposomes, trolox equivalent antioxidant capacity (TEAC), scavenging effect on diphenylpicryl hydrazine (DPPH{radical dot}), and reducing power. These compounds showed potent scavenging activities against DPPH{radical dot} and 2,2′-azino-bis(3-ethylbenzthiazoline-6-sulphonic acid) (ABTS{radical dot}+) radicals, reducing powers, and strong inhibitory capacity on lipid peroxidation. Compound 4a incorporating methyl both at R1 and R2 was found to be the most potent antioxidant described in this study. Compounds 3b and 4b were selected as representative compounds by the National Cancer Institute for screening against anticancer activity and these compounds were found to be cytotoxic against CNS cancer cell line SNB-75 in the primary screen.

Organocatalytic Asymmetric Synthesis of Cyclic Acetals with Spirooxindole Skeleton

An organocatalytic asymmetric synthesis of cyclic acetal with spirooxindole skeleton has been developed via a domino reaction between isatin and γ-hydroxy enones. Bifunctional squaramide catalyst with adamantyl motif was found to be the most effective for the cascade reaction. With 10 mol% of the catalyst, the desired products were obtained in 1.8:1 to 9:1 diastereo- and 86% to >99% enantioselectivities from a range of substituted isatins and γ-hydroxy enones. (Figure presented.).

Synthesis, anti-proliferative activity, theoretical and 1H NMR experimental studies of Morita–Baylis–Hillman adducts from isatin derivatives

Abstract: Quaternary or spirocyclic 3-substituted-3-hydroxy-2-oxindole is considered a privileged scaffold. In other words, it is a molecular core present on several compounds with a wide spectrum of biological activities. Among its precursors, activated ketones (isatin nucleus) can be used as interesting starting points to Morita–Baylis–Hillman adducts derivatives, a class of compounds with good cytotoxic potential. In this paper, we present the synthesis, anti-proliferative activity against lung cancer cell line and a theoretical conformational study of 21 of Morita–Baylis–Hillman adducts from isatin derivatives, by DFT quantum chemical calculations, followed by a SAR and QSAR analysis. Besides, an efficient synthetic protocol and good biological activity profile were highlighted interesting observations about 1H NMR experimental spectra, molecular modeling results and crystallographic data available.
