Therefore, the present study demonstrates that

CH significantly inhibits the growth of MCF-7 human breast cancer cells in vitro, and it provides the underlying mechanism for the anticancer activity. CH suppressed the growth of breast cancer cells without significant toxicity, TPX-0005 making it a promising chemotherapeutic agent for breast cancer treatment; this is likely to be confirmed by further investigation.
