The present invention relates to (a) novel organogermanium compounds represented by the general formula (1) ##STR1## (R.sub.1 to R.sub.6 are independently a hydrogen atom or a lower alkyl group; X is a halogen atom; and Y.sub.1 and Y.sub.2 are independently a hydroxyl group or a group chemically equivalent thereto) or by the general formula (2) ##STR2## (R.sub.1 to R.sub.6 are independently a hydrogen atom or a lower alkyl group, and Z is an oxygen atom or a sulfur atom), (b) processes for producing the above organogermanium compounds, and (c) an agent for inhibiting the activity of opioid peptide-degrading enzyme, containing the above organogermanium compounds as an active ingredient.
                            本发明涉及(a)由一般式(1)表示的新型
