Cytostatic activity of peptide extracts of medicinal plants on transformed A549, H1299, and HeLa Cells.

Biological activity of peptide extracts of medicinal plants was studied on transformed non-small-cell lung carcinoma A549 cells, lung cancer H1299 cells, and cervical cancer HeLa cells at various cell densities. Cell survival and proliferation were evaluated 72 h after treatment with extracts in concentrations of 0.05, 0.

Evaluation of antitumor activity of peptide extracts from medicinal plants on the model of transplanted breast cancer in CBRB-Rb(8.17)1Iem mice.

We studied antitumor effects of peptide extracts from plants on slowly growing mammary adenocarcinoma in CBRB-Rb(8.17)1Iem mice used as a model of breast cancer in humans. The antitumor effect of a single injection of the test peptides was evaluated by the delay of the appearance and growth of palpable breast cancer in mice over 4 weeks.
