Syntheses of Phoyunbenes A‐D and Thunalbene for their Anti‐Inflammatory Evaluation

Abstract

Simple and efficient first syntheses of phoyunbenes A‐D and thunalbene have been developed using Horner–Wadsworth–Emmons reaction as a key step. Later, their anti‐inflammatory effects were investigated in lipopolysaccharide‐induced RAW‐264.7 macrophages. The results revealed that phoyunbenes A‐D and thunalbene showed weak inhibitory activities without cytotoxicity on the production of nitric oxide (NO) which is an important inflammatory mediator.

Mechanistic Model for Deactivation of Direct Internal Reforming Catalysts in Molten Carbonate Fuel Cells

“…During operation electrolyte is transported to the catalyst by creep from the electrode or by deposition of electrolyte vapor. The deactivation in the presence of electrolyte is widely believed to be caused by electrolyte aided sintering, coverage of catalyst surface, blockage of pores, and metal oxides solution formation [1][2][3][4][5][6] . Activity of a catalyst pellet is modeled by considering the physical properties (porosity, surface area) of the pellet.…”
