Problems solved by technology

However, so far, there are few reports on the use of this compound in anti-leukemia treatment research. Our research group has previously confirmed that 6S has a good anti-acute leukemia effect on human leukemia U937, Jurkat and HL-60 cell lines [6-S treatment of cervical cancer The medicinal use of cancer, leukemia and breast cancer, Chinese Invention Patent Publication No.: 101721397A]

Embodiment 1

[0018] Anti-leukemic effect of 6-shogaol in vitro

[0019] Take the cells in the logarithmic growth phase and inoculate 3×10 4 Cells / well were placed on a 96-well plate, and after 4-6 hours of growth, they were administered in groups as follows: Tumor cells were divided into groups without treatment and groups with treatment (concentration: 2.5-30 μM), with 5 or 6 tumor cells in each group. Duplicate wells, in which Salubrinal was pretreated for 1-2 hours, then added 6-shogaol and incubated for 6, 12 and 24 hours, added 20 μl MTT (tetrazolium salt) containing 0.5 mg / ml and incubated for 4 hours, added 100 μl triplex (10% SDS, 5% isobutanol, 0.012mol / L HCL) overnight (or detect after 4 hours in DMSO); place on a micro-oscillator to shake for 10 minutes, and then place on a microplate reader to detect the OD value at 570nm. Each experiment was repeated 3 times. see results figure 1 .

Embodiment 2

[0025] Effects of different concentrations of Salubrinal alone or in combination with 15 μM 6-shogaol on the viability of Jurkat cells

[0026] Take the Jurkat cells in the logarithmic growth phase, treat them according to the method in Example 1, and use different concentrations of Salubrinal (5, 10, 20, 40, 80 μM) alone or in combination with 15 μM 6-S to act on the cells for 12 and 24 hours (molar ratio 1:3-6:1), MTT evaluates cell viability. see results figure 2 .

[0027] from figure 2 We can obtain that Salubrinal at a concentration below 80 μM has no cytotoxic effect on leukemia Jurkat cells. When combined with 15 μM 6-shogaol, it has a significant increase in cytotoxicity and inhibits cell growth. At the same time, we found no concentration-dependent effect of Salubrinal combined with 15 μM 6-shogaol. This suggests that we use low concentration of Salubrinal can synergistically inhibit the proliferation of leukemia cells with 6-shogaol.

Embodiment 3

[0029] Effects of 5 μM Salubrinal and different concentrations of 6-S on the viability of leukemia Jurkat cells

[0030] According to the research basis of Example 3, we used 5 μM Salubrinal alone and or different concentrations (2.5, 5, 10, 15 μM) of 6S combinations (molar ratio of 2:1-1:3) to act on 3, 6, 12 and After 24 hours, the leukemia Jurkat cell viability was analyzed, and the MTT in Example 1 was also used to detect the change of cell viability. The results are shown in image 3 .

[0031] from image 3 The results showed that the 5μM Salubrinal and different concentrations (2.5, 5, 10, 15μM) of 6S composition were more significant than the cell viability reduction of 6S alone, suggesting that 5μM Salubrinal was different from the different concentrations (2.5, 5, 10, 15μM ) of 6S has obvious synergistic effect.

[0032] In order to further confirm the above-mentioned anti-proliferation effect, we detected the apoptosis rate of Jurkat cells treated with 5 μM Salub...

Abstract

The invention relates to the field of natural medicaments, and discloses a compound medicinal composition for treating acute lymphocytic leukemia. The compound medicinal composition is characterized by containing 6-shogaol and Salubrinal. The composition of the 6-shogaol and the Salubrinal can generate biological effect of high-dose 6-shogaol at low-dose compatibility so as to greatly reduce the clinical use dose of the 6-shogaol, reduce potential toxic or side effect, improve safety indexes of clinical treatment and obtain good clinical medicament development prospect.

Description

technical field [0001] The invention relates to the field of natural medicines, and discloses a compound pharmaceutical composition containing 6-shogaol and Salubrinal and its medical application. Background technique [0002] Acute lymphoblastic leukemia (ALL) is a serious and life-threatening progressive malignant disease. ALL accounts for 80% of acute leukemia in children, and the peak incidence is between 3 and 7 years old. ALL can also occur in adults and accounts for 20% of all adult leukemias. In recent years, the disease-free survival rate (DFS) of children with ALL has reached more than 80% [Reducing the dose of anthracycline antibiotics and head radiotherapy can improve the treatment of acute lymphoblastic leukemia in children: clinical reports from acute lymphoblastic leukemia-BFM 90 (Germany- Australia-Swiss Acute Lymphoblastic Leukemia Research Joint Center). Blood, 2000, 95 (11): 3310-3322. St Jude Children's Hospital's long-term treatment results for 11, 12 a...
