Activity Information
| Cell Line | Disease | Cancer Classified | Activity | Assay | Testing Time | Literature |
|---|---|---|---|---|---|---|
| HeLa | Human papillomavirus-related endocervical adenocarcinoma | Carcinoma | 80% Cytotoxicity at 4 µM Approx | MTT assay | 24 h | 1 |

Hemolytic Activity Not available
Normal (non-cancerous) Cytotoxicity Not available
Target Not available
Affinity Not available
Mechanism In addition to rapid membrane-permeabilizing capacities, the peptides can also induce the programmed cell death of cancer cells via both mitochondrial pathway and death receptor pathway, without inducing non-specific immunogenic responses.
