Owing to the strong Lewis acidity of ruthenium porphyrins, a commercial carbonyl ruthenium porphyrin and an amino acid hydrazide can assemble into a sandwich structure. The nature of such a structure is diagnostic of the absolute configuration of the amino acid by circular dichroism.
As analogues of D-cycloserine, the part structure of penicillin and D-D carboxypeptidase substrate of peptidoglycan of bacterial cell wall, D-alanine derivatives and their stereoisomers and D-alanyl-D-alanine derivatives and their stereoisomers (R1-Ala-R2, R1-Ala-Ala-R2 : R1=Z, H ; R2=NHNH2, NHCH3, NHCH2CH2OH) were synthesized. All compounds obtained did not show any antibacterial activity against Staphylococcus aureus, Sarcina lutea, Pseudomonas aeruginosa and Escherichia coli.

both optical isomers of amino acids and isolysergic acid were tested for effects on amine oxidases. There was little action on monoamine oxidase (MO). However, some of the amino acid hydrazides, such as L-leucylhydrazide, turned out to be very effective inhibitors of diamine oxidase (DO). In every instance there was a significant difference between the action of the two antipodes. In seven pairs of antipodal
