The Biosynthetic Pathway of Indole-3-Carbaldehyde and Indole-3-Carboxylic Acid Derivatives in Arabidopsis1[W]
Indolic secondary metabolites play an important role in pathogen defense in cruciferous plants. In Arabidopsis (Arabidopsis thaliana), in addition to the characteristic phytoalexin camalexin, derivatives of indole-3-carbaldehyde (ICHO) and indole-3carboxylic acid (ICOOH) are synthesized from tryptophan via the intermediates indole-3-acetaldoxime and indole-3-acetonitrile. Based on feeding exper...

متن کاملPharmacological properties of some 3-substituted indole derivatives, a concise overview
Indole is a nitrogen-containing heterocycle. It is a very important motif in agriculture and pharmacy. Many compounds containing indole moiety has been isolated form nature. It is also an important part in natural alkaloids. Tryptophan is an amino acid which posses indole. 3-Sustituted indoles are the main group of its derivatives. Because the wide-spread application of 3-substituted indolic co...
متن کاملStudies on alkyl-xanthine derivatives. II. Pharmacokinetic and pharmacodynamic studies of a new bronchodilator, 1-methyl-3-propylxanthine (MPX).
A new xanthine derivative bronchodilator, 1-methyl-3-propylxanthine (MPX), and 1-methyl-3-butylxanthine (MBX) were synthesized. We evaluated their relaxant effects on tracheal smooth muscle isolated from guinea pigs and pharmacokinetic characteristics in rats using 1,3-dimethylxanthine (theophylline, TPH) as the reference drug. Dose-dependent relaxant effects were observed in the concentration ...
متن کاملHighly diastereoselective samarium diiodide induced cyclizations of new 3-substituted indole derivatives.
Herein, we describe the synthesis of new functionalized tricyclic and tetracyclic indole derivatives via samarium diiodide induced ketyl cyclizations. The intermediate samarium organyls were either protonated using different proton sources or alkylated with various electrophiles in a highly diastereoselective manner. The obtained products were subjected to further transformations leading to syn...
