Abstract
The first synthesis of 1-(β-D-glucopyranosyl)brassinin, 1-(β-D-glucopyranosyl)brassenin A, 1-(β-D-glucopyranosyl)brassenin B and 9-(β-D-glucopyranosyl)cyclobrassinin, nucleoside analogs derived from indole phytoalexins, was achieved by linear approach, using the 1-(2,3,4,6-tetra-O-acetyl-β-D-glucopyranosyl)indole-3-carbaldehyde as a starting compound. Antiproliferative and antimicrobial activity of synthesized compounds against murine leukaemia tumor cell line L1210 and selected bacteria and fungi was examined and compared with the corresponding phytoalexin aglycons.
