    A series of new chalcones containing fluoro atom at B ring have been designed, synthesized, and evaluated to be antiproliferative activity against a panel of human tumor cell lines. Some of the analogs (8, 9, 12, 45, 46 and 48) displayed powerful antiproliferative effects to certain human tumor cells, but all of them were devoid of any cytotoxicity towards the normal HEK 293. Acridine orange staining data supported that the cytotoxic and antiproliferative effects of the synthesized analogs on tumor cells are mediated through apoptosis. The compounds 12 and 46 manifested concentration-dependent antiproliferative activity in human hepatocellular carcinoma cell lines using an xCELLigence assay. The structures and antiproliferative activity relationship were further supported by in silico molecular docking study of the compounds against tubulin protein which suggests our compounds interference to cell division.

    Unlocking nature's potential: anticancer potential of Helichrysum sanguineum (L.) Kostel on breast cancer cells and its chemical composition
    (Taylor & Francis Ltd, 2024) Yabalak, Erdal; Bahadirli, Nadire Pelin; Yetkin, Derya; Yaldiz, Fadile Defne; Turkseven, Cagatay Han
    Helichrysum sanguineum (L.) Kostel (H. sanguineum), a member of the Asteraceae family, has been traditionally employed for various medicinal purposes owing to its rich phytochemical composition. This study investigates the anticancer properties of various extracts of H. sanguineum (ethanol, acetonitrile, hexane, and chloroform) against breast cancer cells, shedding light on its chemical constituents and their potential therapeutic effects. In vitro assays demonstrate the profound inhibitory effects of H. sanguineum extract on human fibroblast and breast cancer cells. Furthermore, we elucidate the underlying mechanisms of action, revealing its ability to induce apoptosis and cell cycle arrest in breast cancer cells. The cytotoxicity and apoptosis outcomes in breast cancer cells varied across different extracts, yet no adverse effects were observed on healthy cells at equivalent concentrations. Furthermore, all extracts initially promoted breast cancer cell proliferation, with the chloroform extract notably reducing cancer cell proliferation even at low concentrations. GC-MS analysis identifies the major chemical constituents of the extract, including flavonoids, terpenoids, and phenolic compounds, which likely contribute to its anticancer activity. Our findings highlight the potential of H. sanguineum extract as a natural agent for breast cancer treatment and the need for further exploration of its mechanisms and clinical applications.
