The effects of acute or repeated administration of indole-pyruvic acid (IPA), a keto-analogue of tryptophan (TRP), were studied in various brain areas of rats by measuring the changes of 5-hydroxytryptamine (5-HT) and of norepinephrine (NE) content and metabolism. The analgesic

Structurally related secondary products are rather rarely shared by organisms from different kingdoms. Consequently, the evolution of biosynthetic pathways of defence metabolites between distantly related organisms has not been broadly investigated. Thiazolylindoles are found in Arabidopsis thaliana, as the phytoalexin

Plants have evolved a tremendous ability to respond to environmental changes by adapting their growth and development. The interaction between hormonal and developmental signals is a critical mechanism in the generation of this enormous plasticity. A good example is the
