Abstract

The invention relates to 7-(trimethoxyphenyl)-pyrrolo[2,3-d]pyrimidine. The chemical structure of the compound is shown in a following formula (a), wherein R<1> is selected from 3-indolyl, 4-methylphenyl, phenyl, 4-methoxyphenyl, 4-trifluoromethoxyphenyl, 4-fluorophenyl, 5-(1-methylindazolyl), 6-indolyl, 3-methylphenyl, 3,4-dimethylphenyl, 5-(1-methylindolyl), 3-(1-methylindolyl), 6-(1-methylindolyl), 4-N,N-dimethylphenyl, 4-(1-methylpyrazolyl), 4-vinylphenyl, 3-(1-hydroxymethylindolyl), 3-fluoro-4-methoxyphenyl, 3-amino-4-methoxyphenyl, 3-(1-Boc indolyl) and 4-hydroxymethylphenyl. The 7-(trimethoxyphenyl)-pyrrolo[2,3-d]pyrimidine disclosed by the invention can inhibit tumor cell proliferation and tubulin aggregation and can enable a cell cycle to be stay in a G2 / M period, so that a noveltubulin inhibitor is provided for inhibiting tumor cell proliferation.

Description

technical field [0001] The invention relates to organic compounds, in particular to pyrrolopyrimidine compounds, which can inhibit tumor proliferation and can be used for treating tumors. Background technique [0002] Malignant tumor is the most serious type of disease that endangers human health. Its incidence rate is second only to cardiovascular and cerebrovascular diseases, and it is the second largest "killer" of human health. the first place. Therefore, finding and developing new drugs for treating tumors is a major issue at present. Since microtubules play a key role in the proliferation and division of tumor cells, tubulin is an ideal target for antitumor drugs. [0003] Microtubules play important roles in various cellular processes, including spindle formation, cell shape maintenance and intracellular transport. The function of microtubules in cell mitosis makes them attractive targets for anticancer drugs. Microtubule-targeting agents disrupt microtubule format...
