The compounds are ethylene derivatives which are inhibitors of histamine activity, in particular, inhibitors of H-2 histamine receptors. A compound of this invention is 1-nitro-2-methylamino-2-[2-((4-methyl-5-imidazolyl)methylthio)-ethylamino] ethylene.
The compounds are substituted thioalkyl-, aminoalkyl- and oxyalkyl-guanidines which are inhibitors of histamine activity.
这些化合物是取代的硫代烷基、氨基烷基和氧烷基胍,它们是组胺活性的抑制剂。

The invention provides the use of enzymes derived from plants in biocatalysis. The regio- and stercoselective introduction of an oxygen group into an unactivated organic compound is still a largely unresolved challenge to organic chemistry (Faber, 2000). We have shown that enzymes of Asteraceae species are capable of converting with high regio- and stereospecificity for example sesquiterpene olefins to commercially interesting products.
