  Several cyclic dipeptides were synthesized by refluxing methanolic solution of dipeptide methyl esters in high yield and purity. Cyclic dipeptides prepared by the Fischer method, the Nitecki method, and the present methanol-reflux method were compared with respect to yield and optical purity. The methanol-reflux method usually gave good results. High-performance liquid chromatography was effectively applied to detect racemization.

• Synthetic studies on cyclic octapeptides: Yunnanin F and Hymenistatin

  Two biologically active cyclic peptides, Yunnanin F 8 and Hymenistatin 16 were synthesized and the structures were established on the basis of analytical, IR, NMR and mass spectral data. The newly synthesized compounds were screened for their antimicrobial and pharmacological activities. These cyclic octapeptides have shown moderate to good growth inhibition against bacterial strains and weak activity against fungal strains more than that of the standard drug against only Pseudoinonas aeruginosa but weak to moderate activity against remaining three bacterial strains. They have shown very weak activity against fungal strains. Yunnanin F possessed good anthelmintic activity while Hymenistatin possessed very low activity, but both showed moderate anti-inflammatory activity. (c) 2005 Elsevier SAS. All rights reserved.
