In the present work, we have designed short chain α-helical linear and cyclic peptide from cecropin B having same charge, hydrophobicity, and helicity. The designed compounds were synthesized by using solution phase method. Elucidation of structure of newly synthesized peptides was done by proton nuclear magnetic resonance, Carbon-13 nuclear magnetic resonance, Fourier-transform infrared spectroscopy, Fast atom bombardment mass spectrometry, and elemental analysis. Furthermore, the 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltratrazolium bromide assay was performed for cytotoxicity of synthesized compounds against Dalton’s lymphoma ascites (DLA), Ehrlich’s ascites carcinoma (EAC), and Michigan Cancer Foundation-7 cell lines using 5-FU as a reference compound. Biological evaluation showed that short chain cyclicpeptides were more potent than linear peptides against EAC and DLA cell lines.
