Four diastereoisomers of cyclo(-Asp-Val-): inconsistency of their properties with the proposed structure of cairomycin A.
نویسندگان
چکیده
The four diastereoisomers of cyclo(-Asp-Val-) were synthesized to compare with a proposed structure of cairomycin A. Their antimicrobial activities were determined against both Gram-positive and Gram-negative bacteria. The physico-chemical properties of the isomers were characterized by mp, 1H NMR, IR, FAB-MS, and solubility in solvents, which were different from those reported for cairomycin A.
