Abstract

The invention discloses an amicetin compound. The structural formula is shown in the formula I which is shown in the description, wherien R1 is H or shown in the description; R2 is H or OH; R3 is CH3or CH2CH3 or is shown in the description. The amicetin compound has the colon cancer resisting activity. The invention further discloses a preparation method of the amicetin compound. The preparationmethod comprises the steps that rice is fermented by marine actinomycete rice to obtain extracts, and the extracts are separated and purified by using the chromatographic technique to obtain the amicetin compound. Operation and implementation are facilitated. The invention further discloses application of the amicetin compound in preparing a drug for inhibiting colon cancer.

Description

technical field [0001] The invention relates to the technical field of marine microbial medicines, in particular to a friendmycin compound and its preparation method and application. Background technique [0002] In 1953, Amicetin was discovered for the first time from a soil-derived Streptomyces secondary metabolite. Researchers found that Amicetin had a good inhibitory effect on Escherichia coli and Mycobacterium tuberculosis, so it can be used as a A good potential prodrug for follow-up studies. [0003] Since then, researchers have successively discovered pyrimidine nucleoside compounds, such as cytosaminomycin, oxyplicacetin, streptcytosine, etc., from soil sources or from marine sources of Streptomyces. The structure of this nucleoside pyrimidine compound is similar, with a monosaccharide cytosine as the core, and the difference is that the substituent groups at the amino terminal of cytosine and the 4' position of the sugar ring are different. [0004] According to ...
