A new method for the oxidation of 1, 4-dihydropyridine derivatives by guanidinium nitrate in the presence of silica sulfuric acid under mild, heterogeneous and metal-free conditions
Abstract
In this paper, a new and convenient method is introduced for the oxidation of a variety of Hantzsch 1, 4-dihydropyridine derivatives to their corresponding pyridine compounds using guanidinium nitrate and silica sulfuric acid. The reactions were carried out in dichloromethane at [...]

Activity of 1,3-β-D-Glucanases and Expression of CG-GLU1
in the Mussel Crenomytilus grayanus
(Bivalvia) in Three Bays of the Sea of Japan
Abstract
The level of the specific activity of digestive enzymes and expression of their corresponding glucanase genes (Cg-glu1 ) were studied in Grays mussels, Crenomytilus grayanus, collected from the mussels' assemblages in different parts of Peter the Great Bay (northwestern part of the [...]- 8
