BioAssay: AID 270051

Displacement of [3H]strychnine from strychnine-sensitive glycine receptor in rat spinal cord

A novel class of 3-demethoxy-3-glycosylaminothiocolchicines (7) was prepared and tested for muscle relaxant activity. The syntheses were performed starting from the new 3-amino-3-demethoxythiocolchicine (5) prepared in good yield from 3-O-demethylthiocolchicine (1c) using the Buchwald-Hartwig reaction. The condensation of 5 with a series of pentose and hexose sugars (6) gave a series of more ..

Title: 3-demethoxy-3-glycosylaminothiocolchicines: Synthesis of a new class of putative muscle relaxant compounds.

Abstract: A novel class of 3-demethoxy-3-glycosylaminothiocolchicines (7) was prepared and tested for muscle relaxant activity. The syntheses were performed starting from the new 3-amino-3-demethoxythiocolchicine (5) prepared in good yield from 3-O-demethylthiocolchicine (1c) using the Buchwald-Hartwig reaction. The condensation of 5 with a series of pentose and hexose sugars (6) gave a series of 3-demethoxy-3-glycosylaminothiocolchicines (7). Their preparation was accomplished by adapting and improving a previous procedure for the preparation of N-arylglycosylamines. In particular, replacing traditional heating with microwave irradiation represents the key improvement of the process. The biological activity of the 3-demethoxy-3-glycosylaminothiocolchicines (7) was evaluated on GABA and strychnine-sensitive glycine receptors present in rat brain and spinal cord.
