Abstract

The present invention relates to application of IMB5046 compound in the preparation of antineoplastic drugs. The antineoplastic drug is composed of, by weight, 0.1-99.9% of a compounds shown as a formula I and 0.1-99.9% of pharmaceutically acceptable excipients. The compound shown as formula I can inhibit the polymerization of tubulin and destroy microtubules within cells, has strong cytotoxic activity on tumor cells, especially drug-resistant cells, and can inhibit the growth of xenograft tumor in nude mice. The compound is a tubulin polymerization inhibitor with a novel structure, and has good prospects in developing into antineoplastic drug.

Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of medicine. More specifically, the present invention relates to the use of IMB5046 compound in the preparation of antitumor drugs. [0003] 【Background technique】 [0004] Microtubules are hollow tubular structures composed of 13 fibrils with a diameter of 22 to 25 nm. Each fibril is linearly arranged by tubulin dimers, which are composed of α and β globulins with similar structures. constitute. Microtubules are an important component of the cytoskeleton and play an important role in maintaining cell shape, cell division, intracellular transport and cell movement. During mitosis, microtubules form the spindle, which ensures proper alignment and precise segregation of chromosomes. Rapid spindle microtubule dynamics make cells during division particularly sensitive to microtubule inhibitors (Nat Rev Drug Discov, 2010, 9:790-803). Microtubule inhibitors alter the polymerization state and dynamics o...
