Definitions
- the invention belongs to the field of natural medicines and medicinal chemistry, relates to novel berbamine derivatives, in particular to diimidized derivatives of berbamine, to a method for preparing the same, a composition comprising the same, and a preparation thereof Use in anti-tumor drugs.
- Background technique
- Berbamine is also known as 6,6,7-trimethoxy-2,2,-dimethylberbaman-12-ol (6 5 6',7-trimethoxy-2,2' -dimethylberbaman-12-ol ) is a bisbenzylisoquinoline alkaloid extracted from Chinese herbal medicine Berberis. Xiao Yan
- Berbamine stimulates myeloblast proliferation and increases hematopoietic stem cell colony factor
- the content of (GCSF) promotes the proliferation of bone marrow hematopoietic stem cells and granulocyte progenitor cells, and differentiates into granulocyte cells and promotes the proliferation of leukocytes (Lin Chuanrong, et al., Clinical observation of leukocapac (pefamide) in the treatment of chemotherapy-induced leukopenia, Chinese patent medicine, 1994, 16 (7): 29).
- Berbamine inhibits the proliferation of prostate cancer PC-3 cells by inducing apoptosis and affecting the cell cycle in a time and concentration dependent manner. (Sun Peng et al, berberine induced apoptosis and mechanism of prostate cancer PC-3 cells, Chinese Journal of Experimental Surgery, 2007, 24 (8): 957).
- Berbamine has obvious proliferation inhibition effect and clear apoptosis-inducing effect on K562 cells in vitro, and it has a time-concentration-dependent relationship. In the tumor-bearing mice, berbamine also has a significant inhibitory effect on the growth of K562 cells. In particular, it can down-regulate the expression level of bcr/abl mRNA in tumor tissue cells. (Wu Dong et al., Experimental study on the effect of berbamine on K562 cells in vitro and in vivo, Chinese Journal of Experimental Hematology, 2005, 13 (3): 373). Berbamine inhibits cytotoxic T lymphocytes and promotes the activity of natural killer cells in vitro. It induces high levels of interleukin II in vitro and in vivo.
- IL-2 can avoid the side effects caused by high dose IL-2 treatment of tumors.
- berbamine has a good protective effect on the immune system of radiation-induced mice (Liu Xin et al., Immunomodulatory effects of berbamine on BALB/C mice, Journal of China Medical University, 1996, 25 (3): 229; Luo Chongnian et al. Inhibition of spleen cytotoxic sputum lymphocyte activity by berberine, Chinese Journal of Pharmacology and Toxicology, 1995, 9 (2): 159-160; Ge Mingzhu et al. Experimental study on the immunoprotective effects of mice, J. Immunol., 1998, 14 (4): 238).

- BBM Berylamine
- 6000 well-grown leukemia cells were inoculated into the wells of a 96-well cell culture plate.
- the culture broth was a 1640 cell culture medium containing 10% fetal bovine serum.
- Different concentrations of berbamines were added, mixed, and placed in a carbon dioxide (5% CO 2 ) cell incubator for 72 hours at 37 °C.
- the viable cell concentration was then determined by the MTT method.
- the cell viability was set to 100% in the control group (without compound treatment), and cell viability (%) and 72-hour leukemia cell growth inhibition concentration (72 h IC 5 value) were calculated.

- the culture solution was a DMEM high glucose cell culture medium containing 10% fetal calf serum. Place in a carbon dioxide (5% C0 2 ) cell incubator at 37 °C for 24 hours, then add different concentrations of berbamines, mix and continue to set carbon dioxide (5% C0 2 ) cell incubator 37 °C Cultivate for 72 hours. Then, the concentration of the living cells was measured by the MTT method, and the cell viability (%) after the action of the drug was calculated. In this experiment, the cell viability of the control group (without compound treatment) was set to 100%.
- Table 2 shows that the berbamine derivatives of the present invention are capable of inducing death of human solid tumor cells and inhibiting the growth of these tumor cells, and the activity of the berbamine derivatives of the present invention against solid tumor cells is markedly enhanced as compared with the small indamine itself, wherein the present invention
- the small imide compound (3) has a 6-fold increase in anti-PANC-1 (pancreatic cancer) activity and a 6-fold increase in anti-MCF-7 (breast cancer) activity, and is resistant to HepG2 (human hepatocellular carcinoma, HCC).
