The paper represents a subsequent development of the Life Origination Hydrate Theory (LOH-Theory). It is shown that the natural amino-acids and primary proteins can originate together with DNAs in CH4-hydrate localizations from natural gas and niter; the thermodynamics and chemistry allow such reactions with no external energy sources.

A discussion of 1-hydroxypyranonaphthoquinones is presented that outlines the isolation and biological activity of the known naturally occurring members of this class of compounds. Synthetic approaches developed towards 1- hydroxypyranonaphthoquinones and analogues having potentially improved biological profiles are discussed with particular emphasis on the HRV 3C-protease inhibitor thysanone.

Recent developments in the field of biomimetic systems demand mechanical systems that are capable of delivering high power output per volume or mass. Volume changes within the conducting polymer layers are caused by the oxidation or reduction of the polymer. This volume change is the main source for actuators bending or deforming. Different actuator designs have been explored over the years to maximize bending, di Read More

Our research group has published numerous papers over the last seven years on the reductive Heck reactions of unsaturated N-substituted tricyclic imides which have possible biological activities. The hydroarylation reactions of unsaturated N-substituted tricyclic imides using palladium(II) acetate as a catalyst were studied to obtain a series of new exo-aryl(hetaryl)-substituted tricyclic imides under stereoselective access.

As one of the most popular green solvents and catalysts, ionic liquids have been applied to various application fields including separation and purification, electrochemistry, chemical reaction, cellulose dissolution and so on. However, its further development has been restrained by the preparation and recycling methods due to its unique structure and physical-chemical property. Based on the status, current researches Read More

The recent progress of Ramberg-Bäcklund reaction is reviewed both on the side of the reaction itself and its application in synthesis of functional organic molecules and natural products. In case of RB reaction itself, recent developments towards Meyer's modification and Hendrickson’s improvement are presented in detail, and then followed by new variants of Ramberg-Bäcklund rearrangements, including the epoxy-Ra Read More

Heme oxygenase-1 (HO-1) production is induced in many cell types in response to numerous stimuli, such as the presence of hemes and other oxidants, endotoxin, pro-inflammatory cytokines, or heavy metals, as well as inflammation, hypoxia, or hyperoxia. In addition, HO-1 and the subsequent metabolites of heme catabolism appear to play vital roles in the regulation of important biological responses, including infla Read More
