The invention provides a 1-methyl-6-oxyindole-2-
formamide derivative as well as a preparation method and application thereof, and belongs to the field of
drug synthesis, the
structural formula of the 1-methyl-6-oxyindole-2-
formamide derivative is shown as a general formula I: # imgabs0, R1 is selected from # imgabs1, # imgabs2, # imgabs3, G = C or N, R2 is selected from a group consisting of 1, 2, 3, 4, 5, 6, 7, 8, 8, 9, 10, 12, 13, 14, 16, 17, 17, 17, 17, 17, 17, 17, 17, 17, 17, 17, 17, 17, 17, 17, 17, 17, 17, 17, 17, 17, 17, 17, 17, 17, 17, 17, 17, 17, 17 W = C or N. The 1-methyl-6-oxoindole-2-
formamide mother
nucleus group with
biological activity contained in the compound is further chemically modified to generate a plurality of compounds with higher
biological activity, so that the wide application of the compounds in biological medicines and the development prospect of pharmaceutical preparations are expanded. The compound can significantly inhibit proliferation of
breast cancer,
liver cancer,
pancreatic cancer, gastric
cancer,
lung cancer,
esophageal cancer,
cervical cancer,
multiple myeloma, diffuse large B-
cell lymphoma and other cells at a low dosage (nanomole), and can effectively inhibit STAT3
protein phosphorylation, which shows that the compound has a prospect of being developed into antitumor drugs.
