[0002] Pyrroloindole compounds possess potent antitumor, antibacterial, anti-inflammatory, analgesic, and gastric ailment-relieving effects. On the other hand, due to the strong electron-withdrawing properties and stable carbon-fluorine bonds of trifluoromethyl groups, they can significantly modulate the acidity, lipophilicity, permeability, and metabolic stability of the parent compound.

[0130] Example 4
[0131] The fluoromethyl-substituted pyrroloindole compound 3 synthesized in this invention can undergo a series of reactions to synthesize further derivatives, thus demonstrating its important application value in organic synthesis. For example, fluoromethyl-substituted pyrroloindole compound 3 can undergo Friedel-Crafts acylation, protonation, and β-H elimination in the presence of polyphosphoric acid to obtain product 4.
[0132] The process of synthesizing compound 4a from compound 3oa is as follows:
[0133]
[0134] Add 3oa (70.9 mg, 0.2 mmol) and polyphosphoric acid (PPA, 20.2 mg) to a reaction tube, then seal the tube and place it in an oil bath at 120 °C for 1 hour in air. After the reaction, cool the resulting mixture to room temperature, neutralize with saturated sodium bicarbonate aqueous solution, and extract with ethyl acetate. Combine the organic phases, dry, concentrate under reduced pressure, and separate by silica gel column chromatography (petroleum ether / ethyl acetate = 20 / 1) to give a yellow solid product 4a (30.3 mg, 45%). The characterization data of this compound are as follows: 1 H NMR (600MHz, CDCl3): δ8.59(d,J=7.8Hz,1H),7.95(d,J=7.8Hz,1H),7.75(d,J=7.2Hz,1H),7. 63(t,J=7.2Hz,1H),7.49(t,J=7.8Hz,1H),7.47-7.43(m,2H),7.34(s,1H),7.26-7.22(m,2H). 13 C{ 1H}NMR (150MHz, CDCl3): δ186.8,138.8,136.4,134.2,132.3,131.9,131.2, 130.9,130.1,129.1,127.7,125.2,124.1,123.3,122.7,121.3,119.60(q, 2 J C-F =40.5Hz), 119.58(q, 1 J C-F =265.8Hz), 111.8. 19 F NMR(565MHz,CDCl3):δ-59.44(s).HRMS(ESI)m / z:[M+Na] + Calcd for C 20 H 10 F3NNaO 360.0607; Found 360.0599.

[0146] Example 6
[0147] The anticancer activity of the compounds provided in this invention was evaluated using CCK8 analysis and through cell antiproliferative activity studies.
[0148] The specific method is as follows: First, cells were seeded at a density of 5000 cells per well into 96-well plates containing 100 μL of culture medium per well, and incubated overnight at 37°C and 5% CO2. The next day, 100 μL of the test compound diluted with culture medium (concentration 0.03 nM–30 μM) was added to each well, and the cells were then incubated at 37°C and 5% CO2 for 72 hours. Then, 10 μL of CCK8 was added to each well, and the 96-well plate was incubated at 37°C for 2 hours. The absorbance was measured at 450 nm using an EnVision multilatelbel Reader (PerkinErmer) (with 630 nm as the reference wavelength), and the IC50 was calculated using GraphPad Prism 6.0 software. 50 Values. All experiments were performed with three parallel samples and repeated three times. Hela and A-549 cancer cells were selected as the research subjects, and 5-fluorouracil (5-FU) was used as a positive control.
