Ascorbic acid (AA) and 6-chloro-6-deoxy ascorbic acid (6-Cl-AA) show potential as antitumor agents. These compounds inhibited the growth of various cancer cells, including chemotherapy-resistant types, suggesting their use in cancer treatment.

Area of Science:

  • Biochemistry
  • Oncology
  • Pharmacology

Background:

  • Ascorbic acid (AA) is recognized for its role in preventing and suppressing cancer.
  • Previous studies indicate AA can inhibit tumor cell growth both in vitro and in vivo.

Purpose of the Study:

  • To investigate the effects of ascorbic acid (AA) and 6-chloro-6-deoxy ascorbic acid (6-Cl-AA) on the proliferation of various human and mouse cancer cell lines.
  • To evaluate the potential of these compounds as antitumor agents, particularly against drug-resistant cancer cells.

Main Methods:

  • In vitro testing of AA and 6-Cl-AA on human cell lines (lung fibroblasts, ovarian, colon, laryngeal, cervical, breast adenocarcinomas) and mouse cell lines (fibroblasts, melanoma).
  • Assessment of drug resistance in specific cell lines (HEp2VA3, Helacis, SK-BR-3-Dox).

  • In vivo experiments using solid melanoma B16 tumors to confirm inhibitory effects.

    • Main Results:

    • Both AA and 6-Cl-AA arrested the growth of HeLa, SK-BR-3, SK-BR-3-Dox, L929, and Mel B16 cells.
    • 6-Cl-AA demonstrated stronger suppression of HeLacis, SK-BR-3-Dox, and Mel B16 cell proliferation compared to AA.
    • AA showed activity only against HT-29 cells, while 6-Cl-AA's inhibitory effect was confirmed in vivo on melanoma B16 tumors.

    Conclusions:

    • Ascorbic acid and 6-chloro-6-deoxy ascorbic acid exhibit potential as antitumor agents.
    • These compounds are particularly promising against specific tumor cells, including those resistant to chemotherapy.
