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.

胜肽要扮演宿主免疫机制的一部分或要成为新型态的抗生素不仅要有强大的抗菌活性还需要有高度的选择性，由本实验的结果发现，当抗菌胜肽的正电荷及极性角度增加时，胜肽之抗菌活性会随之增加，当抗菌胜肽的电荷为＋4而极性角度为 140°时，胜肽有最强之抗菌能力及膜渗透活性；而随著胜肽疏水性以及疏水性矩的增加，会增加溶血活性，结果反而降低了抗菌胜肽的选择性。
