The invention belongs to the technical field of
medicinal chemistry, and particularly relates to a series of 15-membered ring quadruple
lactone derivatives with neoantimycin mother
nucleus structures, a preparation method of the 15-membered ring quadruple
lactone derivatives and application of the 15-membered ring quadruple
lactone derivatives in antitumor drugs, wherein the 15-membered ring quadruple lactone derivatives are generated by feeding chemical precursors in the
fermentation process of
streptomyces S.conglobatusATCC 31005. The compound is a fifteen-membered ring quadruple lactone derivative, the C-2 position of the derivative is connected with a
carbonyl group or a hydroxyl group, the C-4 position and the C-9 position are substituted by aliphatic chains with different lengths, and the C-6 position of the derivative is connected with a
benzoic acid group containing F atoms or hydroxyl groups. The compounds have obvious tumor
cell proliferation inhibition activity on
colorectal cancer cells and
lung cancer cells, the inhibition activity is equivalent to that of a control
drug oxaliplatin, and the compounds have weak
toxicity on non-
cancer cell strains. A novel
lead compound is provided for research and development of novel antitumor drugs, and the compound is expected to be developed into a tumor inhibitor.
