In vitro | Selectivity. | A549, HT29 and LoVo cells or P388 and KB cells. |
Kahalalide F displayed selectivity against solid tumor cell lines with IC50 values of 2.5, 0.25 and < 1.0 µg/ml against A549, HT29 and LoVo, respectively, while IC50 values against P388 and KB cells were 10 and > 10 µg/ml, respectively. |

In vitro | Efficacy. | Various prostate and breast cancer cell lines, as well as cell lines derived from normal human tissues. |
Kahalalide F displayed potent cytotoxic activity against various prostate and breast cancer cell lines (DU145, LNCaP, SKBR3, BT474 and MCF7) with IC50 values ranging from 0.07 (PC3) to 0.28 µM. However, non-tumor human cell lines derived from various origins (MCF10A, HUVEC, HMEC-1 and IMR90) were 5- to 40-fold less sensitive, with IC50 values of 1.6 to 3.1 µM. |

In vitro | Activity. | PC3 cells incubated with kahalalide F at 0.25 or 0.5 µM for 12 to 48 h and analyzed by flow cytometry, and PC3 cells incubated with 0.5 µM for 2 to 24 h followed by DNA analysis by agarose gel electrophoresis. |
No hypodiploid peak (characteristic of apoptosis) nor arrest in any phase of the cell cycle for PC3 cells was observed and there was no evidence of a ladder typical of the DNA degradation caused by apoptosis. |

In vitro | Toxicity. | Murine-derived cardiac (H9 c2 (2-1)), skeletal muscle (L8), liver (AML-12), kidney (NRK-52E), and myelogenous stem (FDC-P1) cells exposed to kahalalide F. |
LD50 values against H9 c2 (2-1), L8, AML-12, NRK-52E and FDC-P1 cells were 5 mM, 0.6 mM, 0.17 µM, 1.6 µM and 14 µM, respectively. |

In vitro | Toxicity. | Immunohistochemical method to determine viability of neural cells after kahalalide F exposure. |
At 10 µM, kahalalide F was toxic to CNS neurons, but spared astrocytes, sensory and motor neurons in the spinal cord. |
