CyPep-1 is a novel cationic lytic peptide with antitumor activity. It exerts potent cytotoxicity by interacting with the negatively charged membranes of cancer cells. CyPep-1 demonstrates strong cell lytic activity against cancer cells both in vitro and in vivo, making it useful for researching solid tumors.

CyPep-1 (0-40 μg/mL；15-360 分钟) 以剂量和时间依赖性方式对肿瘤细胞系具有毒性，而对正常细胞系的影响较小。

CyPep-1 (瘤内注射；1200 µg；单剂量) 在乳腺癌小鼠模型呈现出抗肿瘤功效。
