Abstract

The first general methods for the synthesis of 1-substituted trithiagermatranes (3) have been developed using the reaction of tris-(2-mercaptoethyl)amine with trimethoxygermyl compounds (5), sesquioxides (6) and sesquisulfides(7). These newly prepared compounds were found to have the capacity to relieve pain, thus indicating them to have strong inhibitory activity toward a decomposition enzyme for enkephalin which is an opioid peptide in a living body.
