Embodiment 1

[0023] Embodiment 1 synthetic compound 1

[0024] Synthesis of Step 1 Compound II

[0025]

[0026] Dissolve 1.0 g of indole-3-carbaldehyde in 15 mL of tetrahydrofuran, then add 0.5 g of sodium hydrogen to the above solution, stir at room temperature for 5 h, then add 1.5 g of benzenesulfonyl chloride, and continue stirring for 8 h. TLC monitoring. After the reaction was completed, water was added to the reaction liquid to quench the reaction, and then extracted with ethyl acetate-water, the ethyl acetate layer was dried with anhydrous sodium sulfate, and the solution was concentrated to obtain 1.7 g of solid compound II. Yield 86.5%.

[0027] The obtained compound II is identified by nuclear magnetic resonance spectrum and mass spectrometry, and the identification results are:

[0028] 1 H NMR (CDCl 3 )δ10.13(s,1H),8.29(m,2H),8.01(m,3H),7.64(t,1H),7.54(t,2H),7.46-7.37(m,2H).MS(ESI )m / z Calcd.For[M+H] + :286.1; found: 286.1.

Abstract

The invention relates to a 2-(indol-3-yl)-pyridinoimidazole. The chemical structure of the 2-(indol-3-yl)-pyridinoimidazole is represented by formula (I), and R<1> in the formula (I) is a 4-quinolyl group, a 4-isoquinolyl group, a 4-2-methylpyridyl group, a 4-2-methoxypyridyl group or a 4-fluorophenyl group. The 2-(indol-3-yl)-pyridinoimidazole can inhibit tumor cell proliferation, and provides anew inhibitor for inhibiting the tumor cell proliferation.

Description

technical field [0001] The invention relates to organic compounds, in particular to 2-(indol-3-yl)-pyridimidazole 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. [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 formation to inhibit the entry of cancer cells into G2 / M phase and eventually lead to apoptosis of cancer cells. Therefore, tub...
