A series of 11 new pyridoxine-based structural analogs of saccharumoside-B were obtained using original synthetic approach. Antitumor activity of these compounds against nine human tumor cell lines (MCF-7, MDA-MB-231, A-498, SNB-19, M-14, NCI-H322M, HCT-115, HCT-116, and PC-3) was studied, and cytotoxic activity to three normal (HEK-293, Chang Liver, and MSC) cell lines was evaluated. Among the synthesized compounds, 12d, 12e, 13b, 13d, 13e, and 14 exhibited the highest antitumor activity, comparable to that of camptothecin and doxorubicin, but with significantly increased selectivity toward tumor cells.

Method For Producing Low Molecular Weight Aromatic Lignin-Derived Compounds
-
, (2019/04/08)
The present invention relates to a method for producing one or more low molecular weight aromatic lignin-derived compounds. The method preferably comprises providing lignocellulosic material, subjecting the lignocellulosic material to a pulping process, separating pulp to provide a substantially pulp-free process stream comprising a modified lignin-derived component, isolating the modified lignin-derived component, subjecting the isolated modified lignin-derived component to a decomposition step comprising oxidative cracking (cracking and oxidizing) or reducing under the influence of a catalyst or electro-oxidation, and subjecting the resulting products to an isolation step, to provide a low molecular weight aromatic lignin-derived compound. Said compound may be further modified, e.g. by annulation. The inventive method preferably comprises further oxidizing said compound to a redox active compound. Additionally, the present invention relates to compounds obtainable by the inventive method and to an assembly for carrying out the inventive method. Furthermore, the present invention refers to a method for providing an existing pulp and/or paper manufacturing plant with said assembly.

C–H-Activation approach towards the core structure of the alkaloid γ-lycorane
Mishra, Vivek Kumar,Ravikumar, Ponneri C.,Maier, Martin E.
, p. 6499 - 6509 (2016/09/23)
With a view towards the synthesis of lycorane-like structures several N-(pivaloyloxy)benzamides were reacted with cyclohexa-1,3-diene in presence of a rhodium(III) catalyst which resulted via C–H activation in the corresponding tetrahydrophenanthridinones
An alternate method for the synthesis of 2-aryl/alkyl-5-bromo-7-methoxy benzofurans; application to the synthesis of Egonol, Homoegonol, and analogs via Heck reaction
More, Kishor R.,Mali
, p. 7496 - 7504 (2016/11/11)
We herein report the general, versatile, and convenient method for the synthesis of 2-arly/alkyl-5-bromo-7-methoxy benzofurans from easily available o-Vanillin in five steps. These benzofurans was successfully converted into biological active natural products Egonol, Homoegonol, and analogous on applying Heck reaction using ethyl/methyl acrylate in the presence of palladium catalyst.
