For a peptide to act as part of the host defense system or to be of pharmaceutical interest, high antimicrobial activity must be combined by low hemolytic activity. Our results indicated that the antimicrobial activity increased with increasing charge and polar angle, with charge of ＋4 and polar angle of 140° exhibiting the highest antibacterial and membrane permeabilizing activity. Higher hydrophobicity and hydrophobic moment correlated with increased hemolytic activity, thus decreasing selectivity dramatically.
