Disclosed are the general structural formula of LQC-Y as well as the synthesis and use thereof. Pharmacological experiments demonstrated the marked antitumor effect of such compounds. Single day administration of LQC-Y3 to mice at a maximum dose of 6000 mg/kg showed no toxicity response during the 14-day continuous observation period, indicating the high safety of the compounds, and can be used to prepare medicaments for preventing and treating carcinomas such as liver cancer, lung cancer. (General structural formula of LQC-Y) R represents steroid compounds such as cholic acid, deoxycholic acid, ursodeoxycholic acid, chenodeoxycholic acid, and hyodeoxycholic acid; triterpenoid compounds such as oleanolic acid, ursolic acid, pachymic acid, glycyrrhetinic acid and glycosides thereof; emodic acid, emodin and other mono-substituted or poly-substituted structures of anthraquinone core; baicalein, baicalin and other flavone-like compounds; shikimic acid, mono-substituted shikimic acid or poly-substituted shikimic acid; geniposidic acid and other iridoid acid derivatives; paeonol, curcumin and structureal derivatives thereof.
