Abstract
The chemical and biological properties of anti-inflammatory marine natural products whose mechanism of action involves inhibition of phospholipase A2 (PLA2), an enzyme of key importance in the biosynthesis of proinflammatory chemical signals and mediators, has been reviewed. Remarkably, most marine natural products display a selective inhibition profile against secretory PLA2 enzymes, with little or null ability to interfere with cytosolic PLA2. Variabilin, a marine furano-terpene, appears to be a notable exception, endowed with a distinctive dual inhibitor profile towards both secretory and cytosolic PLA2 proteins.
Keywords: inflammation, sesterterpenoids, manoalide, pla2 enzymes, cacospongionolides, luffariellolides, petrosaspongiolides

Catalytic C-H bond activation as a tool for functionalization of heterocycles
The major topic is the functionalization of heterocycles through catalyzed C-H bond activation. The strategies based on C-H activation not only provide straightforward formation of C-C or C-X bonds but, more importantly, allow for the avoidance of pre-functionalization of one or two of the cross-coupling partners. The beneficial impact of ...read more
