Embodiment 1

[0062] Example 1: In vitro biological activity evaluation of naphthalimide-polyamine derivative 6c and cyclosporine A (CsA) combined use

[0063] Test one:

[0064] Human liver cancer cells HepG2 and SMMC-7721 in the logarithmic growth phase were respectively taken, and the cancer cells were digested with trypsin, centrifuged at a speed of 1000r / min for 5 minutes, the supernatant was discarded, suspended in the complete medium, and the number of cells was counted by a hemocytometer. Density is 8×10 3 The inoculum amount of cells / well was inoculated in a 96-well plate, and after 24 hours of adherent growth, naphthalimide-polyamine derivative 6c, cyclosporine A (CsA) was added alone or in combination. The final concentration of single drug is CsA (5 μM), CsA (10 μM), CsA (20 μM), 6c (5 μM), 6c (10 μM), 6c (20 μM); the final concentration of combined drug is 6c (5 μM) + CsA (5 μM), 6c(5μM)+CsA(10μM), 6c(5μM)+CsA(20μM), 6c(10μM)+CsA(5μM), 6c(10μM)+CsA(10μM), 6c(10μM)+CsA(20μM), ...

Embodiment 2

[0089] Example 2: In vivo biological activity evaluation of naphthalimide-polyamine derivative 6c and cyclosporine A (CsA) combined use

[0090] Test nine:

[0091] H22 liver cancer cells from mice (Balb / c mice) were extracted from the abdominal cavity, centrifuged at 1000r / min for 5 minutes, the supernatant was discarded, and washed with pre-cooled saline until no blood remained, usually three times. Each mouse (the mouse is 6 weeks old and weighs about 20g) was inoculated with H22 cells in the tail vein, and the number of cells was 2×10 6. Tumor-bearing mice were divided into four groups, namely blank control group, naphthalimide-polyamine derivative 6c (2mg / kg / day) group, cyclosporin A (CsA, 25mg / kg / day) group and combined Medication group (6c2mg / kg / day+CsA 25mg / kg / day). Naphthalimide-polyamine derivative 6c was administered by tail vein injection, and cyclosporin A (CsA) was administered by intragastric administration for 12 consecutive days. After the experiment, acco...

Abstract

The invention belongs to the technical field of medicinal chemistry, and particularly relates to application of naphthalimide-polyamine derivative combined cyclosporine A in preparation of antitumor drugs. According to the application, a naphthalimide-polyamine derivative and cyclosporine A are combined for use, and the application of the naphthalimide-polyamine derivative and cyclosporine A in preparation of antitumor drugs is provided. Test results prove that compared with a single drug group, the drug combination can significantly inhibit in-vivo metastasis of liver cancer cells and significantly improve the antitumor activity of the single drug group. Meanwhile, compared with a single drug group, the survival rate of tumor-bearing mice can be improved through combined administration. After drug combination, the dosages of the naphthalimide-polyamine derivative and the cyclosporine A can be remarkably reduced, the anti-tumor effect is remarkably improved, and the toxicity to normal hepatocytes is lower than that of liver cancer cells. Combined medication of cyclosporine A and the naphthalimide-polyamine derivative 6c can become a new method for treating liver cancer patients.

Description

technical field [0001] The invention belongs to the technical field of medicinal chemistry, and in particular relates to the application of naphthalimide-polyamine derivatives combined with cyclosporine A in the preparation of antitumor drugs. Background technique [0002] Liver cancer is a malignant tumor of the liver, which is divided into primary liver cancer and secondary liver cancer. Liver cancer is one of the most common malignant tumors and the leading cause of cancer death. Liver cancer can be caused by chronic infection with diseases such as hepatitis B (HBV), hepatitis C (HCV), nonalcoholic steatohepatitis (NASH), or alcoholic steatohepatitis (ASH). Most liver cancers are found in patients with long-term inflammatory liver damage and cirrhosis, and are usually diagnosed at advanced stages. At present, there are few targeted therapy drugs for liver cancer. Therefore, there is an urgent need to explore new and effective therapeutic strategies. [0003] Cyclospor...
