Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to a fused ring diimide derivative, its preparation method and use, belonging to the field of medicinal chemistry. BACKGROUND
[0002] Diimide compounds are an important class of substances in the field of medicinal chemistry, and have many pharmacological activities of interest.
[0003] When diimide is further fused with some fused rings, a unique planar structure can be formed, the molecular volume is greatly reduced, and it can be embedded between the base pairs of DNA double helix, causing the DNA double helix to unwind, thus having unique application value for cell proliferative diseases such as cancer. The fused ring fused with diimide can be various fused rings with conjugated unsaturated structure, which can be carbocyclic or heterocyclic, such as naphthalene, anthracene, pyridine carbazole, etc. There are many reports of antitumor activity of many of these compounds, but few compounds have entered the clinical stage.
[0004] Amonofide is a representative compound among them, and its molecular structure is fused with diimide ring to form a planar structure, which is reported to have cytotoxic activity against colon cancer, lung cancer, gastric cancer, esophageal cancer, leukemia and other cancer cells.

[0129] Example 22: Study of the Anti-tumor Activity of the Compound of Formula I
[0130] Purpose of the test: to test the anti-proliferative activity of the compounds of the application on various tumor cells.
[0131] Test compounds: compounds I-01, I-02, I-03, I-04, I-05, I-08, I-10, I-12, I-15, I-17, I-18, I-20 of the present application; positive drug amonofide; and comparative compounds 1d, 1. Compound 1d is "1d" in the literature Journal of Cancer Molecules, 2010, 5(2): p 41-47, and compound 1 is "compond 1" in the literature Journal of Experimental Therapeutics and Oncology, 2005, 5: p 15-22, both of which are prepared according to the literature method; and positive drug amonofide is from the market.
[0132]
[0133] Test cells: human colon cancer cells (HT-29, COLO 205), human lung cancer cells (NCI-H460, A549), human leukemia cells (HL-60, U-937).
[0134] Test method: Each tumor cell is operated. The cells are cultured at 37°C in the culture medium for 24 hours for standby. The cells in the exponential growth phase are taken, treated with trypsin to prepare a cell suspension, the cell suspension is centrifuged, and then the cell precipitate is resuspended in a small amount of fresh culture medium as a stock cell solution. The stock solution is diluted to the required cell concentration. Each cell concentration is shown in Table 1:
[0135] Table 1: Concentration of each tumor cell
[0136]
[0137]
[0138] Take a 96-well plate, set up a blank control group, a cell control group, and a compound group. The blank control group is added with only 10% PBS per well, and the cell control group and the compound group are added with 100 μL of the above-mentioned concentration of cells per well, and filled with 200 μL of 10% PBS. The plate is placed in an incubator overnight. The compound group is added with 100 μL of each test compound at different dilution concentrations, and the compound dilution concentrations are shown in Table 2.
[0139] Table 2: Dilution concentration of test compound
[0140] SEQ ID NO Concentration of compound (μM) 1 2 3 4 5 6 7 8 1 200 2 66.7 3 22.2 4 7.41 5 2.47 6 0.823 7 0.274 8 0.0914
[0141] After the completion of the addition, the plate was placed in an incubator for 96 hours, 22 μL of Alarmblue (SIGMA R7017) was added to each well, and the plate was returned to the incubator for another 4 hours. After removal, the plate was shaken for 10 seconds, and the fluorescence value of each well was recorded at 530 / 590 nm.
[0142] The above operation was repeated 3 times.
[0143] The Prism 7 software was used to calculate the IC 50 value of each test compound. The IC 50 values were divided into different grades according to their magnitude, i.e., SS: < 1 μM; S: 1-5 μM; A: 5-10 μM; B: 11-20 μM; C: 21-50 μM; D: 51-100 μM; E: > 100 μM. The main results are shown in Table 3:
[0144] Table 3: IC 50 grade of the inhibitory effect of the compounds on tumor cells
[0145]
[0146]
[0147] From the test results, it can be seen that the anti-tumor activity of the compounds of the present application is better than that of the positive drug, amonofide, as a whole. By comparing the compounds of the present application with similar compounds, it can be seen that the inhibitory activity of the compounds of the present application on tumor cells is significantly better than that of compound 1d and compound 1 as a whole. In particular, for colon cancer cells, the activity of some preferred compounds (e.g., compounds I-03, I-04) is more than 50 times that of similar compounds.
[0148] Compound 1d and compound 1 are both structural modifications of amonofide, and the modification is made at the right alkylamino position of amonofide, but in the test case of the present application, the overall anti-tumor activity is not as good as that of amonofide. The difference in activity between the compound of formula I of the present application and compound 1d and compound 1 suggests that in the modification of the right alkylamino of amonofide, the introduction of a heteroatom (R1) and the separation of the heteroatom (R1) and the heteroatom (R2) connected to the right carbonyl group with a carbon chain or a carbon ring are very important for the improvement of activity.
[0149] The present application has been described in detail above with general description and specific embodiments. Modifications or improvements can be made to the present application by those skilled in the art on the basis of the present application, and these modifications or improvements made without departing from the spirit of the present application are all within the scope of the present application.
