Due to low availability of zinc and copper in calcareous soils and the antagonism of these nutrients with each other, the study of their effects on growth and chemical composition of rice seems to have great importance. Also, the relations among different chemical forms of Zn and Cu and plant responses are very important, which can be used in investigation of antagonisms of these nutrients as w...
In the process of screening for squalene synthase inhibitors from microbial fermentation products we have isolated a novel compound, named schizostatin (Fig. 1), from the culture broth of the mushroom, Schizophyllum commune SANK 17785. Schizostatin inhibited rat liver microsomal squalene synthase dose dependently and the IC50 value was 0.84 microM. The inhibition was competitive with respect to...
As a continuous research for discovery of new COX-2 inhibitors, chemical synthesis, in vitro biological activity and molecular docking study of a new group of 1, 4-dihydropyridine (DHP) derivatives were presented. Novel synthesized compounds possessing a COX-2 SO2Me pharmacophore at the para position of C-4 phenyl ring, different hydrophobic groups (R1) at C-2 position and alkoxycarbonyl groups...
This article describes thermal input/concentration output systems processed by chemical reactions. Various sophisticated inputs can be converted into concentration outputs through the double-helix formation of helicene oligomers exhibiting hysteresis. The include high or low temperature, cooling heating state, slow fast and history. basis for properties reactions includes reversibility out equi...
